菜豆属腋芽分化为花芽类型,花芽数很多,蔓性种能分化达18个以上花序,每个花序又可着生6—10朵花。但在高温、潮湿(气温高于24℃、相对湿度72%以上)及其它不利条件下,常会引起落花落果,降低产量。据观察,一般菜豆结荚率仅占花芽分化数6%—10%,占开花数的20%—30%,说明提高菜豆结 Axillary bud axon bud differentiation into flower types, a large number of flower buds, creeping species can be divided into more than 18 inflorescences, each inflorescence can produce 6-10 flowers. However, high temperature, humidity (temperature above 24 ℃, relative humidity above 72%) and other unfavorable conditions, often lead to drop off fruit and reduce production. It is observed that the general rate of bean pod pod flower differentiation accounted for only 6% -10%, accounting for 20% -30% of the number of flowering, indicating the increase of bean knot
