摘要
本文根据已有研究资料,对作物种内混作种植增产效应作了分析。作物种内混作增产效应表现在:①通过多环境、多年份、大面积稳定均衡增产,保证作物整体产量水平的稳定提高;②利用种内不同的基因型混合种植,组成高光效能复合群体,大幅度提高单位面积上的产量;③通过种内混作,降低生产成本和减轻环境污染,维持良好的农业生态环境,保证农业生产的持久发展。
An analysis of increase in yield effect of intercroping for crop intraspecific was conducted in this paper. The performence of effecton increase in yield for crop intraspecific intercroping Wonld be mentioned as follow: ① higher average yield in different enviranments. ② estab- lishing the intraspecific intercroping population with a high photosynthetic rate. ③ reduction of production cost and enviranmental pollution.
