为适应农村经济结构调整的需要,本着使农民增收的目的,研究小麦宽行套种复种三熟种植模式,以充分合理地利用的光热资源,最大限度地提高农田效益。 一、试验基本情况 1.试验设计:共有五个处理（1）冬小麦+花生（套种）+大白菜（复播）（2）冬小麦+玉米（套种）+大白菜（复播）（3）冬小麦+玉米（套种）+黄豆（复播）（4）冬小麦+玉米（套种）+玉米（复播）（5）冬小麦+花生（套种）+玉米（复播）。 2、模式与种植密度（1）冬小麦品种新冬20,播种16行,麦行宽230cm,小麦区占耕地面积的60％。（2）套种花生品种是京花6号,套种时间为4月5日-15日,在麦田预留的120cm空行中铺膜套种2行或3行花生,株距离12cm。种2行花生行距为
In order to meet the needs of the adjustment of rural economic structure, the purpose of increasing peasants’ income is to study the three-cropping mode of multi-cropping with wide-width wheat and to maximize the benefits of farmland with light and heat resources which are fully and reasonably utilized. First, the basic situation of the experiment 1. Experimental design: a total of five treatments (1) winter wheat + peanut (intercropping) + Chinese cabbage (polyculture) (2) winter wheat + corn (intercropping) + Chinese cabbage + Corn (intercropping) + soybean (replanting) (4) winter wheat + corn (intercropping) + corn (replanting) (5) winter wheat + peanut (intercropping) + corn (rewilding). 2) Mode and Planting Density (1) Winter wheat variety Xin Dong 20, sowing 16 rows, wheat row width 230 cm, wheat area accounting for 60% of cultivated land area. (2) The intercropped peanut variety is Jinghua 6, and the intercropping time is Apr. 5-15. In the 120cm blank row reserved in the wheat field, intercropping is carried out for 2 or 3 rows of peanuts, and the distance between the two is 12cm. 2 rows of peanut row spacing
