摘要
2014年以同绿1号为供试材料,研究了不同氮、磷、钾肥配比对绿豆产量构成因子以及产量的影响。通过对绿豆"3414"肥料效应试验,建立肥料施用量与产量的回归方程,求出最佳施肥量。结果表明,科学合理的氮、磷、钾肥配比,不仅能满足绿豆生长发育所需要的营养元素,而且能够促使单株生长发育协调。推荐的最佳施肥量为N 56.7kg/hm2、P(P2O5)76.2kg/hm2、K(K2O)53.5kg/hm2,可获1 526.7kg/hm2的子粒产量。
The effects of different ratios of N, P, K on mung bean production was studied using Tonglti No. 1 as the experimental material. The regression equation of yield with fertilization was established using the ＂3414＂ experimental design in order to obtain the best fertilizer application rate. The results showed that the scientifically reasonable ratios of N, P, K, could not only satisfy the growth need for nutriention, but also promote plant growth and development of mung bean. The recommended best fertilizer application rate was N 56.7kg/hm^2 ,P（ P2O5 ） 76.2kg/hm^2 and K（K2O） 53.5kg/hm^2 ,which could result in mung bean yield of 1 526.7kg/hm^2. This result provided theoretical basis for agri- cultural production of mung bean.
