Li¡VTsai, is a important person of the rationalism in the Middle and late Ming Dynasty. After middle Ming Dynasty, conscience lost the practice of the early aims. People to save the drawback of the Wang's descendants, have filed a new theory to correct the decadent atmosphere, one of the governance drawback of the descendants is the Substance of Nature to be raised. They not only integrate of both Chu's and Wang's though, also according to personal thinking of moral theories to breakthrough the new and review Wang's criterion, also to breakthrough Chu's doctrine system of limitations. Transfer of the Substance of Nature ideologue on the moral principles to chien¡V lo establishing leave Wang's category, appear to the moral theories by the Substance of Mind were turned to Substance of Nature of the rationalism in the late Ming Dynasty, and reflect the complex intertwined politics and society of the current situation and academic thought depravity seeking new response of Late Ming Dynasty. chien¡V lo according to Great Learning propose the doctrine of chih ¡V hsiu, mind¡Bconscience of Wang's though are classified as acquired,and classified the mind as Substance of Nature headed by the system. Unlike Wang's study of mind, is the ontological basis and cause Tong¡VLin resonance for the rescue Wang's correction movement in the positive direction of the late Ming Dynasty.The scholar of Substance of Nature headed are integrate of both Chu's and Wang's though , relies their own thinking of the founding the current situation and academic atmosphere to a new way, and, indirectly, reflect the pulse of the academic atmosphere of the Late Ming Dynasty. Li chien¡V lo stand in it , the chih¡Vhsiu theory has its leading role in the academic trend of the late Ming.

As a result of spatial arrangement discussions and related corn growing recommended techniques, special attention has been given to row spacing reduction. As an example, in the Brazilian Central Plateau, about 50% of corn production has been harvested from double cropping after soybeans. In this situation, the same machinery adjustments used for soybeans are used for double cropped corn, reducing the time required between harvesting and sowing operations. Three experiments were conducted to study the effect of row spacing on corn hybrids agronomic characteristics in the Goiania region, Goias State, evaluating five commercial hybrids in four row spacings and three sowing dates. The experimental design was a 5x4 factorial in randomized blocks with four replications. Row spacing did not significantly affect plant height, ear, stalk and corncob diameter, yield, stalk rot and lodging. The hybrids behavior was significantly different in the four row spacings. The higher yields were obtained in the third planting date under irrigation. / Em resposta principalmente às modificações introduzidas nas características agronômicas dos híbridos de milho e nas condições climáticas e ambientais nas diferentes regiões do Brasil todos os anos, órgãos de pesquisa, empresas privadas e produtores, buscam novas opções em práticas de manejo, visando aumentar a produtividade e a rentabilidade na cultura do milho. Dentre as práticas de manejo que vem recebendo especial atenção destaca-se a redução do espaçamento. O arranjo de plantas na cultura do milho tem sido motivo de discussão e de mudanças nas recomendações técnicas para a cultura do milho nos últimos anos. Um exemplo é o deslocamento da cultura do milho para a safrinha, principalmente na região Centro Oeste do país onde, esta época de cultivo responde por aproximadamente cinquenta porcento da produção de milho. Razões de ordem fisiológica também entram na discussão do espaçamento mais adequado para a cultura do milho. Com o objetivo de avaliar o efeito de espaçamentos em caracteres agronômicos de híbridos de milho foram instalados três experimentos no município de Goiânia. Foram avaliados cinco híbridos comerciais: Fort, P 30K75, PL 6880, PL 6410 e DKB 333B, em quatro espaçamentos: 0,36m, 0,45m, 0,60m e 0,90m em três épocas de semeadura: verão de 2001/02, safrinha de 2002 ambos sem irrigação suplementar e um terceiro experimento implantado na entressafra com irrigação. O delineamento experimental utilizado foi o de blocos ao acaso com os tratamentos arranjados em um esquema fatorial 5x4 com quatro repetições. Os valores médios de altura de planta (AP), diâmetro da espiga (DE), diâmetro do colmo (DC), diâmetro do sabugo (DS), produtividade (P), acamamento (Ac) e quebramento (Qb) não sofreram influência significativa do espaçamento. Os híbridos apresentaram comportamento significativamente diferente entre si, assim como as épocas apresentaram média diferente para os caracteres avaliados, sendo que a época que proporcionou maiores produtividade foi à época de entressafra irrigada.
