在市场经济条件下,单一的种植模式难以实现棉田的高产高效。为提高复种指数,增加植棉效益,近年来出现了多种立体种植模式,现介绍在长江流域棉区的立体多熟八种种植模式: 一、大蒜—豌豆—棉花 种植方式:秋播时,留畦宽4米。大蒜种3幅,每幅宽53厘米;豌豆种4幅,边幅宽40厘米,内幅宽80厘米;大蒜与豌豆隔幅播种,春播时豌豆埋青,棉 Under the condition of market economy, it is difficult to realize the high yield and high efficiency of cotton field by a single planting mode. In order to increase the cropping index and increase the cotton planting efficiency, a variety of three-dimensional planting patterns have emerged in recent years. Now, there are eight planting modes of three-dimensional multi-ripening in the cotton area of ​​the Yangtze River valley: 1. Garlic-pea-cotton planting method: Stay 畦 width 4 meters. Garlic 3, each 53 cm wide; pea species 4, width 40 cm, breadth 80 cm; garlic and pea gap planting, spring planting pea buried green, cotton
