为扩大肥源,改良土壤,提高产量,我们在棉麦复种的基础上,加套苕子和草木樨两季绿肥,收到很好的效果。套种与利用方法(一)作畦畦面根据单作棉田的行距设计。棉花基本上都是采用三组六行一畦面,也有三丈一畦面横种的。行距配制为:特好的地大行3尺,小行1.5尺;上等肥力的大行2.8尺,小行1.4尺;中等肥力的大行2.6尺,小行1.2尺;下等肥力的大行2.4尺,小行1尺。畦面分别为12.1尺,11.2尺,10尺,8.8尺。
In order to expand the source of fertilizers, improve the soil and increase the yield, on the basis of multiple cropping of cotton and wheat, we added two sets of green manure from both prickly heat and herbaceous mulberry trees and received good results. Intercropping and use of methods (a) for 畦 畦 noodles according to a single crop row spacing design. Cotton is basically three groups of six lines of a face, there are three Zhang a face cross-type. Line spacing preparation for: special to the line 3 feet, small line 1.5 feet; fine line of fat 2.8 feet, small line 1.4 feet; moderate fertility of the line 2.6 feet, small line 1.2 feet; Line 2.4 feet, 1 foot small row. Face were 12.1 feet, 11.2 feet, 10 feet, 8.8 feet.
