一、目的与方法 花生覆盖地膜栽培是一项新的农业技术,在国内外都肯定其增产作用,并大量地应用于生产,但增产幅度及经济效益很不一致。我们试图从覆盖地膜结合施肥入手,探索经济而有效的增产途径,以期用较少投资,取得较多产品。施肥水平分三种:(一)无肥区;(二)A水平,即每亩施菜麸200斤,钙镁磷100斤,氯化钾60斤,石灰50斤,折合纯N9.2斤,P_2O_523斤,K_2O39斤;(三)B水平,亩施菜麸100
First, the purpose and methods Peanut film mulching cultivation is a new agricultural technology, both at home and abroad have affirmed its role in increasing production, and a large number of applied to the production, but the rate of increase and economic benefits are very inconsistent. We are trying to start with a combination of film and membrane covering fertilization to explore an economical and effective way to increase production, with a view to making more investment and obtaining more products. Fertilizer levels are divided into three types: (a) no fat area; (B) A level, that is, 200 kg per mu of vegetable bran, 100 kg of calcium magnesium phosphate, 60 kg of potassium chloride, lime 50 pounds, equivalent to pure N9.2 pounds , P_2O_523 pounds, K_2O39 pounds; (C) B level, 100 acres of vegetables bran
