【摘要】 5年试验研究表明,采用杂交棉稀植栽培,在棉花前期间套甜瓜,后期套栽冬季蔬菜所形成的“甜瓜/杂交棉/菜”种植模式,具有较高的经济效益。采用稀植发挥了杂交棉的优势,有利于棉花高产,也有利于甜瓜生长。该模式净产值是常规麦/棉模式的3.13倍。根据市场需求灵活更换与棉花间套的蔬菜品种是实现高产高效的关键。更多还原

【Abstract】 A 5 - year experiment is made in cotton field with melon intercropped at its earlier growth stage and vegetables grown at its later growth stage. The result shows that this farming system model is a high beneficial model. In this model, the cotton is planted in lower density than usual, which is good for the growth of cotton,as well as for that of melon. In comparison with the common farming system model "wheat/cotton", the net output value is 2.13 times higher. It is considered, that how to choose a right type of vegetables according to the change of market is a key point in this model.更多还原
