随着耕地面积的不断减少,各种农作物相互争地的矛盾日益突出,实行棉花与瓜菜等一年四种四收立体栽培,提高复种指数,是实现高产高效的有效措施,生产上适用的最佳模式为:棉花→大蒜→西瓜→菠菜。这种模式的田间种植布局以150厘米为一条种植带,在种植带内做成100厘米宽的高畦和50厘米的低畦,高低畦高度相差12～15厘米。9月下旬在高畦上播种越冬菠菜,品种以越冬性强、丰产、优质的尖叶菠菜等为好。播前每1/15公顷施有机肥1500～2000千克,种子用20℃温水浸种
With the continuous reduction of arable land, the contradictions of various crops competing with each other have become increasingly prominent. The implementation of four kinds of four-crop cultivation in one year, such as cotton and vegetables, and the improvement of the multiple cropping index are effective measures to realize high yield and high efficiency and are suitable for production The best mode is: cotton → garlic → watermelon → spinach. This mode of field planting layout with 150 cm as a planting belt, made in the planting belt 100 cm wide and 50 cm high 畦 畦 height, height 畦 height difference of 12 to 15 cm. In late September sowing winter spinach in the highland, the varieties of winter strong, high yield, high-quality spinach spinach as well. Before sowing 1/15 hectare of organic fertilizer 1500 ~ 2000 kg, seeds soaked with warm water 20 ℃
