临夏高寒阴湿地区耕地主要分布在海拔2000～2600 m 之间,大部分是山旱地。其主栽作物春小麦的产量低而不稳。为了寻找新的增产途径,我所于1995年引进地膜小麦种植技术在和政县卜家庄乡的4个村试种。在是年遭受春夏连续大旱的情况下,试种的0.57 hm~2地膜小麦均获得了较高的产量,最低5475.0 kg/hm~2,最高8179.5 kg/hm~2,平均5803,5 kg/hm~2。另据在拉里洼村下庄社山旱地进 The cultivated land in Linxia alpine area is mainly located at an altitude of 2000 ~ 2600 m, most of which is dryland. The yield of spring wheat, its main crop, is low and unstable. In order to find a new way to increase production, I introduced the technology of plastic filming wheat in 1995 in four villages in Bujiazhuang, Hezheng County. In the spring and summer of successive years suffered a serious drought situation, the trial of 0.57 hm ~ 2 mulched wheat were higher yield, the lowest 5475.0 kg / hm ~ 2, the highest 8179.5 kg / hm ~ 2, an average of 5803.5 kg / hm ~ 2. According to another village in the village of Larry depression into drought
