临汾地区小麦生产由于受土地瘠薄、干旱、寒冷等因素限制,产量没有大的突破。近两年,对小麦进行了广泛的地膜覆盖试验、示范,实践证明了小麦实行全生育期地膜覆盖,具有明显的增温、保墒、节水、改土作用,可使生育期提早,单株生长健壮,成穗率提高。可使小麦生产丰年高产、旱年稳产、增产25％以上;解决小麦与前茬争时、争地矛盾、实现夏、秋双季高产;减少浇水次数和浇水量,扩大浇水面积,实现节水增效。 Due to limited land use, drought and cold in wheat production in Linfen, there is no major breakthrough in yield. In the past two years, wheat has been extensively covered with plastic mulching test. Demonstration and practice have proved that the plastic mulching of wheat during the whole growing period has the obvious effect of increasing temperature, preserving soil moisture, saving water and improving soil, Growing robust, into a spike rate. Can make wheat produce high yield in the harvest year and increase dry output in the dry year by more than 25%; when the dispute between wheat and the former crop is solved, the contradiction between the competition and the land is reached, and the yield is high in summer and autumn; the number of watering and watering are reduced, Achieve water and efficiency.
