我队在一九七四年秋播种冬麦1,500亩,一九七五年春天,除150亩麦田因新开荒地和牲畜践踏有些冻害损失外,90%的麦田全部返青成活,苗全苗壮,为夺取冬麦增产丰收奠定了基础.我队的冬麦生产,从一九七○年到一九七四年,只有两年基本保住了全苗,其余三年均因遭受冻害而有不同程度的越冬死亡,造成小麦产量高一年低一年.特别是一九七○ Our team planted 1,500 hectares of winter wheat in the autumn of 1974. In the spring of 1975, 90% of the wheat fields returned to green and survived except for 150 hectares of wheat fields due to some frost damage caused by newly opened wasteland and livestock. In order to seize the winter wheat yield and laid the foundation for a good harvest.Our team’s winter wheat production, from 1970 to 1974, only two years to save the whole seedlings, the rest of the three were due to frost damage to varying degrees Of the winter deaths, resulting in a year of low wheat yield a year, especially in 1970
