我团是一个谷物农场。地处祖国西北边陲裕民县山区丘陵地带。年降水量400亳米左右,但分布不均匀,冬季雨雪多,风季较长,水土流失较重,没有灌溉条件,属旱作区。为了探索能满足农作物正常生长发育的土壤条件,我们从一九七二年起逐步在一些土壤流失和风害较重的地区改变了犁、耙、播传统耕作法,采用少耕法,只耙地播种,每四、五年深耕一次,少耕面积达4000余亩。
My mission is a cereal farm. Located in the northwestern border of the motherland Yumin County mountainous hilly areas. The annual precipitation is about 400 millimeters, but the distribution is uneven. In winter, there is more rain and snow, longer windy season, heavier soil erosion and no irrigation conditions. In order to explore soil conditions that can meet the normal growth and development of crops, we have gradually changed plows, rakes and sowing practices in some areas where soil loss and wind damage have been severe since 1972, adopting less tillage and only harrowing Seeding, once every four or five years time, less cultivated area of 4,000 acres.
