1 落花、落果菜豆植株花数多,增产潜力大,但如果温度、湿度、日照长短及土壤盐碱度等各种原因不适植株生长,常造成严重的落蕾、落花、落荚现象,结荚率一般只有20%～30%,最多不超过40%～50%。1.1 养分不均衡,营养不良豆类蔬菜的开花结荚与营养生长有密切关系。一般植株基部的花序开花结荚比中、上部的花序多。中部比上部多,花序之间着果有互相制约的倾向。前一花序结荚多时,后一花序结荚常
However, if temperature, humidity, sunshine duration and soil salinity are unfavorable to plant growth, they often cause serious falling buds, falling flowers, falling pods, Rate is generally only 20% to 30%, up to no more than 40% to 50%. 1.1 Nutrient imbalance, malnutrition Beans and vegetables flowering pod and vegetative growth are closely related. The inflorescences of the basal plant usually bear more pods than the middle and upper inflorescences. Central than the upper part of the inflorescence with fruit tend to restrict each other. Former inflorescence pods for many years, after the inflorescence pod often
