晋城市位于山西省东南部,地处太行、太岳、中条三大山系交汇地段。耕地面积279万亩,其中旱地面积占到90%以上。农业生产条件的总体状况是地形复杂,年降水量较多(600～680mm),但时空分布极不均匀,季节性干旱十分严重,是典型的旱作农业区。近年来,我们积极开展旱作节水技术的试验研究和技术攻关,总结出了以W型地膜覆盖为基本框架,构建了W型地膜覆盖、蓄水渠、旱井相配套的保水、聚水、蓄水相结合的治旱体系,并在此基础上探索高效经济作物种植模式,逐步形成了一套W型地膜覆盖节水高效种植技术模式。
Jincheng City is located in southeastern Shanxi Province, is located in Taihang, Taiyue, Zhongti three mountain intersection intersection lot. The area of arable land is 2.79 million mu, of which dry land area accounts for more than 90%. The overall condition of agricultural production conditions is complicated topography with large annual rainfall (600 ~ 680mm), but the distribution of time and space is very uneven. The seasonal drought is very serious, and it is a typical dry farming area. In recent years, we have actively carried out experimental research and technical research on water-saving technologies for rainfed farming. We concluded that W-type mulching is the basic framework, and W-type mulching and water storage, , Water storage combined drought control system, and on this basis to explore high-efficiency cash crop planting patterns, and gradually formed a W-film mulching water-saving and efficient planting technology model.
