【摘要】 通过对夏大豆密、肥试验研究及产量构成因素的统计分析,明确了夏大豆高产栽培最适密度为每亩1.4万株,最佳施肥量为磷二铵20kg/亩;在合理密植的前提下,以酌控分枝数、力争饱荚数、确保百粒重为主攻方向。更多还原

【Abstract】 The analyses of field experiment on plant density and fertilixer and of factors composed of yield for summer soyceanhas shown that proper plant density is 14 kilo-plants per mu,and optimum amout of nitrogen fertilixer is 20kg amminium phosphate per mu for high-yield culture of summer soybean. The chief objective of high-yield culture of summer soybean is properly ensuring branches per plant,increasing full bean pods and ensuring grain weigyt.更多还原
