基因型与群体结构对春大产豆量的效应研究
EFFECTS OF GENOTYPE AND THE POPULATION STRUCTURE ON THE YIELD IN SPRING SOYBEAN

摘要: 本文采用再裂区设计研究基因型、行、畦宽度和每穴苗数对春大豆产量的效应,结果表明,莆豆8008具有高产的基因型特征,在福建春大豆区可大力推广。同时春大豆高产应以窄畦窄行(0.8米种两行)和每穴3株较好,这样不仅可充分利用边际效应,而且可保证每亩2.5万左右的株数,是春大豆高产的基本条件。Abstract: The designed method of split-split-plot has been applied to study the effect of genotype, row spacing and the number of plants per hill on the yield in spring soybean the results show that pudon 8008 is a good variety with high-yielding characteristics and it is feasible to be popularized in spring soybean area in Fujian. Furthermore, it is essential to make high yield by row spacing 0.8M and 3 plants per hill in spring soybean. It can fully utilize border effect, and also maintain pipulation with high yield about 25?103 plants per mu in spring soybean.
