西部旱区绿豆高产群体结构与功能优化

研究了适合西部旱区种植的绿豆品种在不同密度、施氮水平下,对高产群体结构的影响以及群体结构构成因子的变化。结果表明,同绿1号绿豆种植密度为18万株/hm2、施氮水平为135 kg/hm2、绿叶面积指数为1.766,适应旱区环境,群体结构合理,产量达到最大,为1 610.85 kg/hm2,实现了绿豆合理的高产高效群体结构。

High Yield Population Structure of Mung Bean in Arid Western China and Function Optimization

In the paper mung bean varieties suitable planting density for cultivation in arid western China and yield components factor under different nitrogen levels were analyzed and the effect in different treatments on high yield population structure and population structure factor changes analyzed. Results showed that Tonglyn 1 in planting density of 180 000 plant/hm2, 135 kg/hm2 nitrogen level, the leaf area index was 1.766, have adapted to arid regions, the population structure is reasonable, the production of 1 610.85 kg/hm2, which realized the maximum, implements reasonable structure of high yield and high efficiency mung beans group.
