秋菜豆苗期正处高温多雨季节,后期温度又低,生产难度大,在栽培上要抓住以下技术环节: 1.选用耐热抗病品种。如丰收1号、白架豆、九粒白、双季豆等。 2.严格掌握播期。播种过早,开花期遇高温,易落花落荚,锈病严重;播种过晚,生长期短、产量低。一般蔓生种在早霜前90～100天播种为宜,矮生种可延后12天。 Autumn bean seedling is in high temperature and rainy season, the latter part of the temperature is low, the production is difficult, in the cultivation to seize the following technical aspects: 1. Selection of heat-resistant varieties. Such as harvest on the 1st, white beans, nine white, double beans and so on. 2. Strict control of sowing. Early sowing, flowering encounter high temperature, easy to fall off pods, rust serious; sowing too late, short growth period, low yield. The general vine in 90 ~ 100 days before early frost sowing is appropriate, dwarf species can be delayed 12 days.
