“两粮两经”宽带耕作制是充分挖掘粮油主产区的农田潜力,合理解决粮经净地矛盾,提高全年农田生产能力的有效途径,是适宜当前种植业结构调整的最佳种植模式。“两粮两经”宽带耕作制是以4米左右为一种植带(适应机械作业),秋播时以种麦为主(约占3.5米宽),种植油菜或越冬蔬菜为辅(约占0.5米宽),而夏播时则以花生等经济作物为主(占3.5米宽),以玉米等粮食作物为辅(占0.5米宽)。通过“高套低”、“低套高”立体种植结构的台理措配,使夏、秋时期的光、热、水等自然资源得到充分利用,最大限度提高光能利用率和土地产出率。其种植模式主要有三种类型:1.种麦时留出预留行,实行4米左右的带距,每带种6楼18行习啧(宽约3.5米),然后留出0.5米预留行,预留行内种油菜或越冬蔬菜,待油菜收后在预留行两侧套种2行大穗型玉 The Broadband Farming System of Liang Liang Er Jing is an effective way to fully tap the potential of farmlands in the main producing areas of grain and oil, rationally solve the contradiction between grain, land and net and improve the productivity of farmland throughout the year. Planting patterns. Broadband farming system is based on a belt of about 4 meters (adapted to mechanical operation). When it is autumn sowing, mainly wheat seeds (about 3.5 meters wide) are supplemented by the planting of rape or overwintering vegetables About 0.5m wide), while summer sowing is dominated by cash crops such as peanuts (3.5m wide) and supplemented by corn and other food crops (0.5m wide). The natural light, heat, water and other natural resources in summer and autumn are fully utilized to maximize the utilization rate of light energy through the “high-low-density” and “low-height” stereoscopic planting structures And land productivity. There are three main types of planting patterns: 1. Reserve wheat reserve when the line, the implementation of about 4 meters away from the belt, each with a floor 18 18 Xi Xi (width of 3.5 meters), and then set aside 0.5 meters reserved OK, set aside rows of rapeseed or winter vegetables, rapeseeds collected after the reservation on both sides of the intercropping 2 rows of large spike jade
