我场位于柴达木盆地南缘,海拔2791米,农业耕作历史较短,属新垦区,年无霜期100天左右。一年一熟,以种植春小麦为主,小麦播种面积占粮食作物87％左右。豌豆则是我场轮作换茬的主要豆科作物,种好豌豆是实现我场粮食持续增产的重要措施。1976年—1979年,我所进行了豌豆高产栽培试验研究,四年都种草原7号豌豆,有三年的实际亩产在较大面积上突破了千斤(表1)。其中1976年亩产为1045斤,1978年亩产为1023.4斤,1979年亩产为1027.6斤。
My field is located in the southern margin of the Qaidam Basin, 2791 meters above sea level, agricultural farming shorter history, is a new reclamation area, the annual frost-free period of 100 days. One year a year, mainly to grow spring wheat, wheat sown area accounts for about 87% of food crops. Peas are the main legume crops for crop rotation and replacement. The planting of good peas is an important measure to realize continuous increase of grain yield in our field. From 1976 to 1979, I conducted high-yielding pea cultivation experiments. For the past four years, all the grasslands on the 7th pea were planted. Three years of actual mu production broke through a large area (Table 1). Among them, the yield per mu in 1976 was 1,045 jin, and the average yield per mu in 1978 was 1,023.4 kilos. In 1979, the per-mu yield was 1,027.6 kilos.
