近几年来,安徽沿江两熟棉区,棉田套种绿肥发展很快,绿肥品种主要的是黄花苜蓿、苕子和蚕豆等。为了经济有效地利用绿肥,我们对棉田绿肥翻压利用,进行了试验研究,现综合试验结果介绍如下: 一、翻压时期及方法对腐烂的影响绿肥翻压后腐烂的快慢,因不同的绿肥品种、不同翻压时间及方法而有所差异。从表1可以看出,一般苕子腐烂最快,其次是黄花苜蓿,蚕豆最慢。如同在4月15日 In recent years, two cotton fields along the Yangtze River in Anhui Province, cotton intercropped with rapid development of green manure, green manure varieties are mainly alfalfa, razor clam and broad bean and so on. In order to use green manure economically and efficiently, we carried out experimental research on green manure utilization in cotton field. The results of the comprehensive test are as follows: I. Effect of Tensioning Period and Method on Decay The rate of decay of green manure after pressing is different due to different green manure Variety, different pressure time and methods are different. As can be seen from Table 1, the most common decayed rotten seeds, followed by alfalfa, beans the slowest. As on April 15
