我队地处青藏高原干旱、低温地带,海拔三千零六十米左右。常年降雨量为二百四十至二百五十毫米,水源不足,风沙较大,没有绝对无霜期。土地偏碱性,含磷量极少,肥料缺乏,自然条件较差。农作物生长常受早、晚霜和冰雹的危害。无产阶级文化大革命前,粮食亩产长期徘徊在二百斤上下,好的年景,亦不过三百余斤,处于单产不稳,总产不高的状况。 My team is located in the Tibetan Plateau arid, low temperature zone, about 3,060 meters above sea level. Perennial rainfall of 240 to 250 millimeters, lack of water, sand blown larger, there is no absolute frost-free period. Alkaline land, minimal phosphorus content, lack of fertilizers, poor natural conditions. Crops often suffer from morning and evening frost and hail. Before the Great Proletarian Cultural Revolution, the per-mu yield of grain lingered for a long time up to two hundred jin and the good years were no more than three hundred jin. It was in a situation of unstable yields and low total output.
