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。
In 2014, with the same green No. 1, the effects of different N, P and K fertilizers on the yield components and yield of mung bean were studied. Through the mung bean “3414 ” fertilizer effect test, establish the regression equation of fertilizers application rate and yield, find out the best amount of fertilizer. The results showed that the scientific and rational nitrogen, phosphorus and potassium fertilizers not only can meet the nutrient elements needed for growth and development of mung beans, but also can promote the coordination of single plant growth and development. The optimum fertilization rate was N 56.7kg / hm2, P (P2O5) 76.2kg / hm2 and K (K2O) 53.5kg / hm2, yielding 1 526.7kg / hm2 of grain yield.
