播种时,在播种沟内条施肥料,使肥料靠近种籽以提高肥效的方法早为我省农民所创造应用。特别是棉花作物,应用种肥十分普遍,仅就1964年运城、永济、临猗、闻喜、曲沃等5个县的统计,棉田施用种肥面积占总面积的80—85％。为了查明种肥对于棉花的增产作用,我们于1964年在运城公社路北街大队、永济栲栳公社吕辙大队、临猗大阎公社大阎大队和闻喜东镇公社东姚大队等4个基点布置试验,同时结合群众大田试验进行调查研究。现将所得资料整理如下,供各地施用种肥时参考。
When sowing, sowing in the trench fertilizer, fertilizer close to the seeds in order to improve fertilizer efficiency as early as our province farmers to create applications. Especially cotton crops, the application of fertilizer is very common, only in 1964 Yuncheng, Yongji, Linqu, Wenxi, Quwo and other five counties statistics, the application of cotton seed fertilizer area of 80-85% of the total area. In 1964, in order to find out the effect of planting fertilizer on the cotton yield, we organized a series of experiments at Lubei Street Brigade of Yuncheng Commune in 1964, Lude Brigade of Yongji Peasant Commune, Dayan Brigade of Linyi Dayan Commune and Dongyue Brigade of Wenxi East Town Commune A base point layout test, combined with mass field trials to investigate. The information is now organized as follows, for reference throughout the application of fertilizer.
