近年来我国花生地膜覆盖栽培发展很快,1985年面积有370万亩,比1984年140万亩扩大了230万亩。我省研究此项工作较晚,有关报道不多。为了探明地膜花生栽培的增产效益及增产原因,我们于1983—1985年连续进行了3年(3造)试验,现将结果综述如下。一、试验材料和方法花生品种:“粤油551—116”。地膜:透明薄膜,宽幅1.6米,厚度0.015毫米。除草剂:每亩用25％恶草灵125毫升。 (一)试验处理共4个处理:(1)全生育期盖膜(全膜);(2)齐苗后揭膜(齐揭);(3)露地免中耕
In recent years, the peanut mulching has developed rapidly in China. In 1985, it covered an area of 3.7 million mu, an increase of 230 million mu from 1.4 million mu in 1984. Our province to study this work late, the report is not much. In order to ascertain the yield-increasing benefits of plastic film mulching cultivation and the reasons for increasing yield, we conducted a continuous three-year (3-year) trial in 1983-1985. The results are summarized as follows. First, the test materials and methods Peanut varieties: “Guangdong Oil 551-116”. Film: Transparent film, width 1.6 m, thickness 0.015 mm. Herbicide: 25% of the evil spirit Spirit 125ml per acre. (A) A total of four treatment treatments: (1) full-term cover film (whole film); (2) Qi Miao Houjie (Jie exposures); (3)
