菜豆同腋芽分化花芽类型，花芽数很多，但在高温、潮湿及其他不利条件下，常会引起落花落荚，降低产量。一般结荚率仅占化芽分化数的6％－10％，占开花数的30％左右，说明提高菜豆结荚率的潜力很大。一、合理肥水1．施肥应掌握“基肥为主，追肥为辅，氮、磷、钾配合施用”的原 Bean buds with the axillary bud differentiation type, a lot of flower buds, but in high temperature, humidity and other adverse conditions, often lead to falling falling pods and reduce production. Generally pod rate of only 6% -10% of the number of buds, accounting for about 30% of the number of flowering, indicating that there is a great potential to improve the rate of bean pod. First, a reasonable fertilizer Fertilization should master the “basic fertilizer, supplemented by top dressing, nitrogen, phosphorus and potassium with the application of” the original
