【摘要】 对四个大豆品种的产量、品质、产量性状及对氮磷钾的吸收利用能力进行了比较研究。结果表明,不同大豆品种间产量性状存在着差异,对氮磷钾的吸收利用能力不同,导致产量的差异。对大豆产量的相关因素分析表明,大豆产量与生殖生长期植株干重、株荚数、株粒数、百粒重关系密切;养分利用能力强,利于产量的提高。更多还原

【Abstract】 The comparison between four species soybean of yield, qualities, yield character and ability using N,P,K fertilizers were studied in this article. The results showed that there were different on the yield character and the ability of using N, P, K fertilizers, which caused the difference in yield. The analyzing of correlation factors indicated that soybean yield was related to plant dry weight, number of pods per plant, number of grains per plant and 100 grains weight, moreover, the strong ability of using nutrition was useful to increase yield.更多还原
