我团地处昭苏高寒非灌溉区,海拔1600～1700米,冬寒夏凉,四季不明显,年平均气温2—3℃,绝对无霜期60～85天。年降雨500毫米左右。土壤属草甸黑钙土,有机质含量5％以上,土层深厚,适宜小麦、油菜等作物的生长。但由于长期以来,耕作粗放,作物种类单纯:结构不合理,重茬面积多,年限长(3—6年);倒茬轮休少(10—15％)。致使野燕麦泛滥成灾。全团12万亩耕地,野燕麦每亩100万株以上的面积有7—8万亩,占60—70％。燕麦草和作物争水、争肥、争光、争空间。历年来,小麦平均亩产只有50—100公斤,油菜平均亩产只有20—50公
My mission is located in Zhaosu cold non-irrigated area, elevation 1600 ~ 1700 meters, cold winter and cool, seasons is not obvious, the annual average temperature of 2-3 ℃, the absolute frost-free period of 60 to 85 days. About 500 millimeters of rainfall. Soil is a meadow of calcareous soil, organic matter content of more than 5%, deep soil, suitable for the growth of wheat, rapeseed and other crops. However, due to extensive cultivation for a long time, the crop types are simple: the structure is irrational, the area of stubble is long, and the period of time is long (3-6 years); the crop rotation is less (10-15%). Wild oat flooding. The whole group 120,000 acres of arable land, wild oats more than 1 million acres per acre area of 7-8 million mu, accounting for 60-70%. Oats grass and crops fight water, fight fat, glory, fight space. Over the years, the average yield of wheat is only 50-100 kilograms, average yield of rape only 20-50 public
