大豆花荚脱落现象是大豆本身对不良环境条件的一种适应性表现。据统计,大豆花荚脱落率一般可达45%—70%,其中,一般落花占60%左右,落荚占30%左右,落蕾占10%左右。大豆花荚脱落现象在整个开花阶段均能发生,因此了解大豆花荚脱落的原因及防止措施是提高大豆产量的关键。一、花荚脱落原因1、与大豆品种类型和花荚所处部位有关。一般有限结荚习性或生育繁茂的品种,以及生长发育较晚的部位脱落率较高,反之,则低。
Soybean flower pod shedding phenomenon is an adaptive performance of the soybean itself to adverse environmental conditions. According to statistics, the loss rate of soybean flower pods is generally up to 45% -70%, of which, the general falling flowers account for about 60%, falling pod accounts for about 30% and the falling buds occupy about 10%. Soybean flower pod shedding phenomenon can occur throughout the flowering stage, so understanding the reasons for soybean flower pod shedding and prevention measures is to increase the key to soybean yield. First, flower pods shedding reasons 1, and the types of flowers and pods where the parts. Generally limited pod habit or longevity breeds, and growth and development of the higher part of the exfoliation rate is higher, otherwise low.
