摘要
采用小麦春玉米夏玉米间套作种植模式，随着年总产量的提高，其经济效益同步增长。麦王玉复合群体的产值和纯收入达27045．9元／hm2和14884．95元／hm2，比着玉米一熟单和小麦玉米一年两熟复种产值提高91．50％和20．38％，纯收入提高74．70％和11．81％。根据作物生长发育过程中的空间差和时间差，选择越冬菠菜和早熟秋白菜参与到模式中进行间套作，增加复合群体空间层次与集约程度，其产值与纯收入增长幅度更大。
The intercropping pattern could also increase economic benifits while getting high yield of wheat,early-grown corn and summer-grown corn The output value and net income reached 27045.9 yuan/hm2 and 14884.95 yuan/hm2, the output value in-creased by 91. 5% and 20.38% and net income by 74. 70% and 11. 81% than that of monocropping spring corn and wheat-corn sequencial cropping pattern According to the difference of time and space at stages of crop growth and development, the output value and net income could be further increased by multiple intercropping and relay in-tercropping with overwatering spinach and early mature Chinese cabbage.
