近年来,洛阳市豆角在种植过程中出现一些问题,突出表现为:一是苗期不长以及苗期徒长、死棵越来越严重;二是结荚期病虫害严重。因此,在豆角种植上要抓好以下环节:1.适期播种,采用优良抗病品种,选择两年以上无种植过豆科作物的田块种植。豆角比较喜欢高温,耐热性强,种子发芽最适温度25℃~30℃,生长适温为20℃~25℃,在夏季35℃以上高温仍能正常结荚,但在10℃以下较长时间低温,生长受抑制。所以要掌握播种时
In recent years, some problems occurred in the planting process of Luoyang Beans, highlighted as follows: First, the seedling stage is not long and the seedling stage is long and the dead tree is more and more serious; Second, the pest and disease in the podding stage is serious. Therefore, in the cultivation of beans to grasp the following aspects: 1. Sowing the appropriate time, the use of fine varieties resistant to more than two years without the selection of legumes planted field plots. Beans prefer high temperature, heat resistance, seed germination optimum temperature 25 ℃ ~ 30 ℃, growth suitable temperature 20 ℃ ~ 25 ℃, the summer 35 ℃ above the normal temperature can still be normal pod, but longer than 10 ℃ longer Low temperature, growth inhibition. So to grasp when sowing
