我省主产棉区每年有百万亩棉田倒种小麦。这类地区肥水条件好,生产水平高。棉花茬地是小麦的良好前茬,为减少夏玉米回茬麦的低产面积,当地采用棉茬耪麦,以利适时播种,提高产量。但播种浅,质量差,冬春雨雪多,气候温暖时,产量较高,反之则产量低。因此耪种面积年度间变化大。棉茬麦面积减少,玉米茬麦面积就扩大。为解决这一问题,近两年来在渭南辛市基点开展“二二三”套种,取得一定成效,介绍如下。一、具体做法和增产效果。棉花、小
Each year, the main cotton producing area in our province has 1 million mu of inverted wheat in cotton fields. Fertilizer and water conditions in these areas is good, high level of production. Cotton stubble is a good wheat stubble, in order to reduce the summer corn stubble wheat low yield area, the local use of cotton stubble barley, in order to facilitate timely sowing, increase production. However, sowing shallow, poor quality, snow and rain in winter and spring more, the climate is warm, higher yield, otherwise the yield is low. As a result, the annual change of area varies greatly. Cotton stubble wheat area reduced, wheat stubble wheat area expanded. To solve this problem, in the last two years, Weinan Xin City base to carry out “two two three” interplanting, and achieved some success, introduced below. First, the specific practices and increase production efficiency. Cotton, small
