山西省壶关县属典型的北方旱作雨养农业区,而秸秆覆盖技术是改善农田小气候的重要措施,但传统的覆盖方式存在一些难以解决的问题。因此,经多年试验示范,总结出旱地秸秆沟埋加地膜覆盖技术模式。该模式具有秸秆腐烂好、能蓄水保墒、提高地力等优点,非常适宜在北方及旱作玉米生产区推广。 Huaguan County, Shanxi Province is a typical northern rainfed rainfed farming area, and straw mulching technology is an important measure to improve the microclimate of the farmland. However, there are some problems that are difficult to be solved in the traditional ways of covering. Therefore, after many years of experiments and demonstrations, the straw mulching and plastic film mulching technology for dry land has been summarized. This model has the advantages of good stalk rot, water storage and soil conservation, improved soil fertility, etc., and is very suitable for popularization in the north and dry corn production areas.
