甜菜地膜覆盖栽培农业部全国农业技术推广总站冯岩甜菜地膜覆盖栽培是甜菜生产上的一项新技术。地膜覆盖甜菜有增温、保墒、抑制土壤盐分上升的作用；可以改善甜菜的生态条件，利于保苗，促进块根生长，延长生育期，获得高产。按目前的生产水平，一般较露地栽培亩增产块根...
Beet mulching cultivation of the Ministry of Agriculture National Agricultural Technology Extension Station Feng Yan beet film mulching cultivation is a new technology in the production of sugar beet. Covering sugar beet has the effects of warming, preserving soil moisture and inhibiting the increase of soil salinity; it can improve the ecological conditions of beet, help maintain seedlings, promote root growth, extend the growth period, and achieve high yield. According to the current level of production, generally more acres than the open planting cultivation root ...
