半干旱地区农作物全膜覆盖双垄面集雨沟播试验示范研究

榆林素有十年九旱之称，是典型的雨养农业区，干旱依然是困扰农业发展的主要因素，目前≤15°的旱坡地有1058．1万亩，占全市耕地总资源的64．3％。全膜覆盖双垄面集雨沟播技术是适宜于在粮、油等经济效益高的作物上应用，却具有投资少，见效快、易操作等优点，将为榆林旱作农业发展开辟新途径。

Study on the Semi-arid Areas of Crops Membrane Covering the Whole Face Rainwater Harvesting Double Ridge and Furrow Sowing Technology

Yulin is an area of nine years drought out of ten, it is a typical area where the agricultural relying very much on rain. Arid is still a main factor influencing the agricultural development. At present there has 10,581,000 Chinese acres with ≤ 15° the dry land on slopes, about 64.3% of the whole farming land. The entire membrane covering the double ridge surface collection rain trench planting technology is suitable in the grain, the oil crops. It requires few invests, yield greater economic results, easy to operate, which will open the new way for Yulin dry agricuhural development.
