摘要
冬小麦是黄土高原地区的主要粮食作物之一 ,其产量高低直接影响到该区粮食总产。试验结果表明 ,在地膜覆盖条件下 ,黄土高原南部地区冬小麦适期播种时期为 9月 2 0~ 2 5日 ,适宜播种密度为 6~ 9粒 /穴 。
Winter wheat is one of main grain crops in the region of Loess Plateau.The experiments show that suitable planting time of winter wheat ranges from 20 to 25 in September in southern region of Loess Plateau under the film cover, and feasible planting density is 6 to 9 seeds grains per hole. And these measures are favor of optimum use of soil water and improving water use efficiency.
