在我们地区,蚕豆普通存在着开花多结荚少、落花落荚严重的问题。一般亩产只有200多斤,低者仅有100来斤。为了解决这个问题,我们做了一些调查和观察,提出以下几方面的初步看法。一、落花落荚的原因据调查,我区蚕豆成荚率只有40%左右,造成结荚率低的原因主要有两方面:(1)开花时正值春雨连绵,花粉粒大量吸水后膨胀而破裂,丧失授精能力。另外,这时气温较高,虫害多,也常造成落花烂荚。(2)栽培管理不当,营养物质供应不足或分配不合
In our region, there is generally the problem of broad bean blossom with less pods and severe fall and fall pods. General mu yield of only 200 kilos, the only low 100 pounds. In order to solve this problem, we made some investigations and observations and put forward the following preliminary observations. First, the reasons for falling pods According to the survey, the area pod rate of beans is only about 40%, resulting in low pod rate for two main reasons: (1) flowering at a time when spring rains, pollen grains after a large number of water swelling Rupture, loss of fertility. In addition, when the temperature is higher, more pests, but also often caused by falling rotten pods. (2) improper cultivation management, inadequate supply of nutrients or disagreement
