近几年来,有些人認为,棉花和山芋間作,可以改善棉田光照、空气、营养等条件,不失为获得棉花增产的一种技术措施。但从历年生产实践出发,权衡利害得失,对棉芋間作的这种認識,是值得商榷的。从1959年起,安庆专区樅阳县开始試行棉芋間作。到1961年,全县植棉三万亩,棉芋間作就有四千四百亩,占14.7%;其中以湯沟公社最多,間作二千四百亩,占公社植棉总面积29.7%。1961年底和1962年初,我們对樅阳的棉芋間作情况做了一次全面調查,結果发現棉芋間作并沒有起到增产作用,相反的,却給棉花生产的发展带来不良的影
In recent years, some people think that intercropping with cotton and potato can improve conditions of light, air and nutrition in cotton fields, which is a technical measure to increase cotton yield. However, it is debatable that this understanding of cotton-taro intercropping must be weighed against the background of past production practices and the balance between gains and losses. From 1959 onwards, Anqing Prefecture Zongyang County trial intercropping cotton. By 1961, the county thirty thousand acres of cotton, cotton-taro has four thousand four hundred acres intercropping, accounting for 14.7%; of which Tang ditch most communes, intercropping two four hundred acres, accounting for the commune total area of cotton planting 29.7 %. At the end of 1961 and early 1962, we conducted a comprehensive investigation of the cotton-taro intercropping in Zongyang and found that cotton-taro intercropping did not play an increasing role. On the contrary, we had a bad influence on the cotton production.
