贵州省农科院武陵山开发联络组从1987年开始,针对铜仁、松桃两县花生面积大,产量徘徊不前,常年单产仅70～100公斤的状况,于1987年至1989年展开了地膜覆盖花生栽培技术试验示范,取得了较大的效益。地膜覆盖后花生生育期比露地栽培缩短8～10天,植株增高4.4～7厘米,侧枝增长4～12厘米,果仁增重,单株生产力提高4～6克,饱果率提高6.5％以上,平均亩增产壳花生88.9公斤,增产率达68.5％,每亩纯收入增加 141.1元,投入产出比为1:4.1。本文对三年试验示范结果进行了总结分析,以期为更大面积示范推广该技术提供科学依据。
Guizhou Province Academy of Agricultural Sciences Wuling Mountain Development Liaison Group since 1987, for Tongren, Songtao two counties peanut area, yield stagnating, perennial yield of only 70 to 100 kg, from 1987 to 1989 launched a film Covering peanut cultivation technology demonstration, and achieved greater benefits. After plastic film mulching, the growth period of peanut was shortened by 8-10 days compared with the field cultivation, the height of the plant increased by 4.4-7 cm and the lateral branch increased by 4-12 cm. The weight gain of nut was increased by 4 ~ 6 g per plant and the full fruit rate was increased by 6.5% , An average of 88.9 kilograms of shell peanut yield increase, the yield was 68.5%, net income per acre 141.1 yuan, input-output ratio of 1: 4.1. This paper summarizes the results of three years of experimental demonstration, with a view to provide a scientific basis for a larger area to demonstrate the promotion of the technology.
