我们在蔬菜、旱地作物地膜复盖栽培的启示下,于1982年冬季进行了油菜地膜复盖栽培试验,取得了很好的效果。用地膜复盖栽培的油菜,表现茎秆粗壮,分枝、角果、每荚种子数都增多,比对照增产125.2％,增产效果明显。现将试验结果报告如下。材料与方法试验所用地膜为萍乡市塑料一厂生产的厚为0.015—0.02毫米、幅宽6市尺的聚乙烯微膜。试验地为青隔泥稻田土,土质差,
Inspired by the plastic film mulching cultivation of vegetables and dry land crops, we conducted the rape mulching and mulching cultivation experiment in the winter of 1982 and achieved good results. Covered with plastic film cultivation of rape, stem sturdy stalks, branches, fruit, per pod seed number increased more than the control 125.2% yield increase significantly. The test results are reported below. Materials and Methods The plastic film used for the experiment was a polyethylene micro film with a thickness of 0.015-0.02 mm and a width of 6 feet produced by Pingxiang Plastic Factory. Experimental site for the green mud paddy soil, poor soil quality,
