摘要
为了创新与集成绿豆抗旱高产栽培技术体系,研究了不同绿豆品种在不同密度、不同覆膜方式下的产量构成因子,分析评价了绿豆抗旱高产群体结构及栽培技术对群体结构与功能的调节效应。结果表明:绿豆品种同绿1号密度在18万株.hm-2,沟垄覆膜,群体结构合理,功能最优,绿叶叶面积指数为2.046,产量1 819.5kg.hm-2达到最大,在旱区为适宜的种植模式。
In order to innovation and integration mung bean high yield and drought resistant cultivation technology system,the yield oomponents of different mung bean varieties with different density and different film mulching modes were studied, the high yield and drought resistam population structure and the adjustment effect of the technology on population structure and function were evaluated. The results showed that:Tonglv No. 1 with the density of 180 000 plants·hm^-2 and film mulching on ridge and over furrow,had reasonable population structure and the best function, green leaves leaf area index was 2. 046, field achieved maximum,was 1 819. 5 kg· hm^-2 ,it was an appropriate planting mode in arid regions.
