Increasing the success of community transfer when creating species-rich meadows using green hay strewing

Wilkes, Alison January 2017 (has links)
Methods of increasing the number, diversity and evenness of plant species establishing in species-rich meadows created or enhanced with green hay from a semi-natural source meadow were studied. Three experiments were conducted on grasslands in Birmingham and Herefordshire: (i) Comparisons of species and community transfer resulting from green hay being strewn in consecutive years onto a glyphosated receiver meadow. (ii) The effect on species-richness of introducing green hay into a species-rich created meadow. (iii) The effect of different levels of disturbance in combination with grazing on the introduction of species into an existing created species-rich meadow. Strewing hay twice resulted in vegetation containing more species and species with higher frequencies compared with haying once. Hay strewing increased the number of species in an existing species-rich sward and also increased the frequency and abundance of existing species. Source species frequency, flowering/seed set date and established life strategy had an important influence on species transfer. In general, species that did not transfer were those found at low frequencies in MG5 Cynosurus cristatus – Centaurea nigra community meadows and with stress-tolerance as part of their life strategy. There was a statistically significant three-way interaction between haying, grazing and disturbance. As several terrestrial orchid species are associated with this habitat type, techniques and media for axenic seed germination and propagation of a selected local MG5 meadow orchid species (Dactylorhiza fuchsii) were assessed. Comparisons were made of two media types in combination with mycorrhizae and a source of complex carbohydrates. Of these, oats medium with fungi produced significantly higher germination rates than other tested media. Oats medium also proved the most suitable medium for protocorms when replated, producing the greatest increase in protocorm length compared with Western medium after 15 weeks of growth.

Využití procesu vysokotlaké hydrolýzy kyselinou dusičnou při produkci bioplynu ze sena / The application of the process of high-pressure hydrolysis with nitric acid at the production of biogas from hay

VANĚK, Zbyněk January 2012 (has links)
This thesis deals with the technology of the high pressure hydrolysis with nitric acid (HNO3) in biogass production from the hay. The theoretical part is focused on the basic information about the acid hydrolisis. Much attention is ingaged in the lignocellulosic materials and methods of their treatment.The hay was crushed, pelleted and subsequently subjected the acid hydrolysis in the high-pressure hydrolyzer (UV CZ 21314) at pressures (0,475 MPa, 0,934 MPa, 1,611 MPa). As the hydrolysis reagent was used highly concentrated (65%) nitric acid (HNO3). The pressure was achieved in the hydrolyzer by the steam in temparature of 190°C, the residence time of the phytomass in the machine was 500s. Based on the mapping process with wide CO2 production were selected the interesting areas, which were subsequently carried out detailed mapping process using batch simulations at CH4 production. After the mathematical interpolation of the maxima the values were used in the economic analysis, that fully respects the technological possibilities and legislative constraints.

Oito ovelhas da raça Santa Inês, após um período de adaptação de 45 dias recebendo 50% de feno de alfafa e 50% de silagem de milho, foram distribuídas ao acaso em dois tratamentos: o primeiro consistiu de animais que receberam feno de alfafa (C3-FA) e o segundo, dos animais que receberam apenas silagem de milho (C4-SM). Para mensurar o turnover de carbono (substituição isotópica) nas fezes e sangue em determinado intervalo de tempo, foi utilizada a função exponencial do tempo. Apenas os valores isotópicos das fezes atingiram o patamar de equilíbrio, indicando valores de meia-vida de 1,2 e 1,0 dias para os tratamentos C3-FA e C4-SM, respectivamente. Já no sangue, o tempo de coleta dos dados (104 dias) foi insuficiente para encontrar o patamar de equilíbrio isotópico, indicando uma troca de carbono lenta. De acordo com os resultados deste estudo, pode-se concluir que o sangue apresenta turnover lento indicando o sinal isotópico de dietas antigas; e as fezes, turnover rápido, indicadas para refletir dietas recentes, próximas da fase de avaliação / The aim of this work was to evaluate the carbon turnover and half-life on feces and blood sheep, fed on C3 and C4 plants, using the stable isotopes technique. Eight Santa Ines sheep, after 45 days as adjustment period receiving 50% of alfalfa hay and 50% of corn silage, were randomly assigned to two treatments: the first one the animals fed on alfalfa hay (C3-FA) and the second one the animals fed on only corn silage (C4-SM). The time exponential function was used to measure the carbon turnover (isotope substitution) on feces and blood in a certain period of time. Only the isotope feces values reached the plateau value, indicating half-life of 1.2 and 1.0 days for C3-FA and C4-SM treatment, respectively. The data collection time (104 days) for blood was not enough to find a plateau isotope, indicating a slow carbon exchange. So we can infer that the blood has a slow turnover, indicating isotopic signal of ancient diets; and the feces showed a fast turnover, being used to reflect recent diet, next to the evaluation period

Enhancing the Cooling Capacity of Roof Ponds Using Polyethylene Band Filter

January 2013 (has links)
abstract: With the desire of high standards of comfort, huge amount of energy is being consumed to maintain the indoor environment. In US building consumes 40% of the total primary energy while residential buildings consume about 21%. A large proportion of this consumption is due to cooling of buildings. Deteriorating environmental conditions due to excessive energy use suggest that we should look at passive designs and renewable energy opportunities to supply the required comfort. Phoenix gets about 300 days of clear sky every year. It also witnesses large temperature variations from night and day. The humidity ratio almost always stays below the 50% mark. With more than six months having outside temperatures more than 75 oF, night sky radiative cooling promise to be an attractive means to cool the buildings during summer. This technique can be useful for small commercial facilities or residential buildings. The roof ponds can be made more effective by covering them with Band Filters. These band filters block the solar heat gain and allow the water to cool down to lower temperatures. It also reduces the convection heat gain. This helps rood ponds maintain lower temperatures and provide more cooling then an exposed pond. 50 μm Polyethylene band filter is used in this study. Using this band filter, roof ponds can be made up to 10% more effective. About 45% of the energy required to cool a typical residential building in summer can be saved. / Dissertation/Thesis / M.S.

Aimed to study the recommendation of soy cultivation techniques for the Pernambuco Agreste. The experiment was conducted in field conditions during the growing season of 2013, the Federal Rural University of Pernambuco, Academic Unit of Garanhuns. The effect of the presence and absence of fitoestimulante was observed in different crop densities (12, 14, 18 and 22 plants per meter) is also carried cut at 45 days after emergence. Was installed in a randomized block design, split plot (4x2) schema. The density of 22 pl.m-1 promotes initial growth of plants. Density of 14 pl.m-1 estimulate ® increases the yield. Density of 22 pl.m-1 without estimulate® enhances biological productivity, the rate of crop growth and yield of straw. 12 pl.m-1 with estimulate® favors the harvest index. When done cutting, planting density of 22 pl.m-1 promotes germination speed index and the presence of estimulate ® increases the first count, biomass productivity at the time of harvest, final biomass and total biomass of soybean matched against the absence of stimulating® increases grain yield, harvest index and grain filling rate, this density. The densities of 14 and 18 pl.m-1 estimulate® reduces the mortality of plants. The use of estimulate® stimulates the growth of the crop and straw yield a density of 22 pl.m-1. / No agreste pernambucano, a produção de soja pode trazer grandes benefícios financeiros para os produtores locais e contribuição significativa na atividade leiteira por meio de seu emprego como fonte alternativa de proteína para o rebanho, mas a ausência de aparato tecnológico e incentivo técnico para sua produção faz com que essa leguminosa não seja explorada. Objetivou-se estudar a recomendação de técnicas de cultivo em soja para o Agreste pernambucano. O experimento foi conduzido em condições de campo, no ano agrícola de 2013, na Universidade Federal Rural de Pernambuco, Unidade Acadêmica de Garanhuns. O efeito da presença e da ausência do fitoestimulante foi observado em diferentes densidades de cultivo (12, 14, 18 e 22 plantas por metro) e também realizado o corte aos 45 dias após emergência. Foi instalado em delineamento de blocos ao acaso, em esquema de parcela subdividida (4x2). A densidade de 22 pl.m-1 favorece o crescimento inicial de plantas. Na densidade de 14 pl.m-1 o estimulate® aumenta a produtividade de grãos. Na densidade de 22 pl.m-1 sem estimulate® favorece a produtividade biológica, a taxa de crescimento da cultura e o rendimento de palha. 12 pl.m-1 com estimulate® favorece o índice de colheita. Quando realizado o corte, a densidade de cultivo de 22 pl.m-1 favorece o índice de velocidade de germinação e a presença do estimulate® aumenta a primeira contagem, produtividade de biomassa na ocasião do corte, a biomassa final e a fitomassa total de soja em contra partida, a ausência do estimulante® aumenta a produtividade de grãos, índice de colheita e taxa de enchimento de grãos, nesta densidade. Nas densidades de 14 e 18 pl.m-1 o estimulate® reduz a mortandade de plantas. O uso do estimulate® estimula o crescimento da cultura e rendimento de palha na densidade de 22 pl.m-1.

Made available in DSpace on 2017-07-10T17:48:01Z (GMT). No. of bitstreams: 1 Michele_Pasqualotto.pdf: 1033333 bytes, checksum: 74dd4a169bab4794a14ac5626c6548a3 (MD5) Previous issue date: 2014-02-28 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The present study aimed to evaluate the intensity of conditioning of plants Tifton 85 with use of Mower Conditioner with free swinging flail fingers and storage times on the curve of dehydration, occurring fungus, nutritional value and in vitro digestibility of dry matter of hay Tifton 85. During the dehydration of the plants was also evaluated gas exchange. The dehydration curve was determined in the whole plant in ten times to the baling. The zero time corresponded to the plant before the cut, held 11h00 hour and other collects were made 8h00, 10h00, 14h00 and 16h00 hours. The experimental design was randomized blocks with two intensity of conditioning (high and low) and tem times of sampling, with five replicates. For the determination of gas exchange during the dehydration Tifton85 Evaluations were performed on mature leaves, situated in the upper middle third of each branch before the cutting and were performed each hour, for 4 hours. We used a portable meter infrared gas analyzer IRGA (6400 at). The variables analyzed were (A) photosynthesis, (gs) stomata conductance, (C) internal CO2 concentration, (E) sweating, (EUA) efficiency of water use, (EUAi) intrinsic efficiency to the water use. Subsequently the determination of fungi present in green plants and hay, where the grass samples were collected at the time of cutting , baling in, 30, 60 and 90 days of storage was made. It was observed that the dehydration of Tifton 85 was held in 49 hours, who is considered an ideal time for drying hay and differences between intensities of conditioning about on dry matter were taken during dehydration, but equaled the end of process. Gas exchanges were more intense before the cut, and, after cutting were decreasing to cease within 4 hours. The dry matter (DM) is smaller on the time when cutting when compared to other storage times. The crude protein did not differ between the intensity of conditioning or storage times staying on average 121.65 g kg-1. The lowest values of acid detergent insoluble protein (PIDA) were obtained with low intensity of conditioning after 30 days of storage, 64.8 g kg -1 DM. The contente of neutral detergent fiber (NDF), didn´t result no difference both to the time before the cut as to intensity of conditioning of Tifton 85. The in vitro digestibility of dry matter (DM) of Tifton 85 did not differ on the times of storage evaluated or difference on the intensities of conditioning. In samples collected during the storage period up to 90 days after dehydration was not detected the presence of fungi, with less than 30 colony forming units (CFU) per plate count. The use of mowers Conditioners in diferente intensities of injury does not accelerate the time of dehydration plants Tifton 85. Proper drying and storage under favorable conditions do not favor the growth of fungi in Tifton 85 / O presente estudo objetivou avaliar a intensidade de condicionamento de plantas de capim Tifton 85 com uso de segadeira condicionadora com batedores de dedos livres e tempos de armazenamento sobre a curva de desidratação, ocorrência de fungos, valor nutricional e digestibilidade in vitro da matéria seca de feno Tifton 85. Também avaliou-se as trocas gasosas durante a desidratação das plantas. A curva de desidratação foi determinada na planta inteira em dez tempos até o enfardamento. O tempo zero correspondeu à planta antes do corte, realizado as 11h00 horas e as demais coletas foram realizadas as 8h00, 10h00, 14h00 e 16h00 horas. O delineamento experimental adotado foi em blocos casualizado com duas intensidades de condicionamento (alta e baixa) e dez tempos de amostragem, com cinco repetições. Para a determinação de trocas gasosas durante a desidratação do Tifton 85, foram realizadas avaliações em folhas maduras, situadas no terço médio superior de cada ramo antes do corte e a cada hora, por 4 horas. Utilizou-se um medidor portátil de trocas gasosas por infravermelho IRGA (6400 xt). As variáveis analisadas foram (A) fotossíntese, (gs) condutância estomática, (Ci) concentração interna de CO 2 , (E) transpiração, (EUA) eficiência do uso de água, (EUAi) eficiência intrínseca do uso de água. Em uma segunda etapa do presente trabalho avaliou-se o valor nutricional do feno de Tifton 85 e para isto adotou-se o delineamento em blocos casualizado em esquema de parcelas subdivididas no tempo, com dois tratamentos alocados nas parcelas: alta e baixa intensidade de corte e cinco tempos nas subparcelas: corte (tratamento adicional), enfardamento, e 30, 60 e 90 dias de armazenamento. Posteriormente foi realizada a determinação dos fungos presentes nas plantas verdes e no feno, onde coletaram-se amostras do capim no momento do corte, no enfardamento, 30, 60 e 90 dias de armazenamento. Observou-se que a desidratação do Tifton 85 realizou-se em 49 horas, sendo considerado um tempo ideal para secagem do feno e as diferenças entre intensidades de condicionamento sobre os teores de matéria seca se deram durante a desidratação, mas se igualaram no final do processo. As trocas gasosas foram mais intensas antes do corte e após o corte foram diminuindo até cessar nas 4 horas seguintes. Os teores de matéria seca (MS) apresentam-se menores no momento do corte quando comparados aos demais tempos de armazenamento. A proteína bruta não diferiu entre intensidade de condicionamento nem tempos de armazenamento ficando em média 121,65 g kg -1 . Os menores valores de proteína insolúvel em detergente ácido (PIDA) foram obtidos com baixa intensidade de condicionamento aos 30 dias de armazenamento, 64.8 g kg 1 de MS. O teor de fibra em detergente neutro (FDN), não apresentou diferença tanto para o tempo antes do corte quanto para intensidade de condicionamento do Tifton 85. A digestibilidade in vitro da matéria seca (DIVMS) do capim Tifton 85 não diferiu entre os tempos de armazenamento avaliados e nem entre as intensidades de condicionamento. Nas amostras coletadas durante o período de armazenamento, até 90 dias após a desidratação não foi constatada a presença de fungos, apresentando contagem inferior a 30 unidades formadoras de colônia (UFC) por placa. O uso de segadeiras condicionadoras em diferentes intensidades de injúria não acelera o tempo de desidratação das plantas de capim Tifton 85. A secagem adequada e o armazenamento em condições favoráveis não propiciam o crescimento de fungos em feno de Tifton 85
