小麦套种花生一年两熟种植面积发展很快,我国北方地区套种面积与春播面积基本持平,并有扩大的趋势。其经济效益也比较好。一、几种优化模式的设计1.大垄宽幅麦套种覆膜花生栽培模式播种小麦时两犁扶大垄,垄距90厘米,垄沟内播20厘米宽的小麦宽幅带,整成垄宽70厘米,高10～13厘米、垄面50厘米的大垄。于次年春小麦返青时覆盖75厘米宽的地
Wheat intercropping peanut planting area developed rapidly one year, the intercropping area in northern China and spring sown area is basically the same, and there is an expanding trend. Its economic benefits are better. First, the design of several optimization modes 1. Large ridge width wheat intercropping peanut cultivation modes of planting two sowing wheat sowing wide ridge, ridge spacing of 90 cm, 20 cm wide ditch sowing wheat wide band, the whole ridge Width 70 cm, height 10 ~ 13 cm, 50 cm ridge ridge. In the spring of next spring, the wheat covered 75 centimeters wide
