蚕豆作为用地和养地相结合的粮食作物和经济作物,在夏粮生产上占有很重要的地位。影响蚕豆产量的原因,除病害之外,花荚脱落是一个十分突出的重要因素。为了寻求减少蚕豆花荚脱落的途径,我们从1982年开始,进行了一系列较为系统地观察和探讨。 一、花荚形成和脱落的一般情况 蚕豆花呈蝶形,花朵簇生在叶腋间的花梗上,形成一个短总状花序。花朵顺序自植株下部向上无限生长,花簇由里向外顺序开放。据几年观察:从第一片复叶算起,平均 Broad beans, as the combination of land and raising land, are important food crops and cash crops in summer grain production. Affect the yield of broad beans reasons, in addition to disease, flower pods shedding is a very prominent and important factor. In order to seek ways to reduce the shedding of broad bean pods, we have conducted a series of more systematic observations and discussions since 1982. First, the formation and fall of flower pods General situation Broad bean was butterfly, flowers clustered in the leaf axils peduncle, forming a short raceme. The order of the flowers grows infinitely upwards from the lower part of the plant, and the flower clusters are open sequentially from the inside to the outside. According to several years of observation: From the first compound leaves, the average
