应用地膜复盖栽培作物的新技术在我国发展很快。各地试验、示范、推广资料说明,不论是旱地、水地、还是中度盐碱地,采用地膜复盖的大部分作物,都获得了明显的增产效果,特别是棉花,花生、瓜果等经济作物,增产、增收效果更为显著。地膜复盖棉花多用于农业栽培技术方面,缺少在灌溉条件下地膜复盖后土壤水分变化及其对作物生态影响的资料,为了弥补这一不足,从1982年开始,先后在运诚、临汾和晋中棉区的十个灌溉试验站,对地膜复盖棉花的耗水量,耗水规律和灌溉制度进行了试验观测,获得了省水、增产、增收的明显效果。
The application of mulching film cultivation of new technologies in our country developed rapidly. Experiments, demonstrations and promotion materials all over the country showed that most of the crops covered with plastic mulch have gained significant yield-increasing effects, especially in cash crops such as cotton, peanuts and fruits, whether in dryland, water or moderate saline soil. Increasing production and increasing revenue are more significant. Film mulch cotton used in agricultural cultivation techniques, the lack of irrigation under the conditions of plastic film mulching soil moisture changes and its ecological impact on crops information, in order to make up for this deficiency, from 1982 onwards, has shipped in Cheng, Linfen and Ten irrigation experimental stations in the Jinzhong cotton area were used to test the water consumption, water consumption and irrigation regimes of cotton covered with plastic film, and the obvious effect of saving water, increasing yield and increasing income was obtained.
