我们大队因无霜期短,过去一直种植春小麦。春播、夏收不但劳力紧张,用水,用肥矛盾也十分突出。春麦收后赶死赶活复种一点糜子亩产只有百十斤,有时还成熟不了。为了改革旧耕作制度,发展农业生产,迅速提高单位面积产量,我们从一九七○年开始,引进试种冬麦,经过反复实践,逐步实行了改部分春麦为冬麦,抓前熟促后熟的耕作方式,冬麦播种面积扩大了近四百亩,占水地小麦播种面积的40％左右。亩产多在六百五十斤至七百斤。 Our brigade has been cultivating spring wheat because of its short frost-free period. Spring sowing, summer harvest not only labor stress, water, fertilizer contradictions are also very prominent. Spring wheat rush to live after the catch live a little broomcorn per mu only 100 pounds, and sometimes not mature. In order to reform the old farming system and develop agricultural production and rapidly increase the yield per unit area, we started to test winter wheat cultivation in 1970. After repeated practice, we gradually implemented the transformation of some spring wheat into winter wheat, Cooked farming methods, winter wheat sown area expanded nearly four hundred acres, accounting for about 40% of the water area of ​​?? wheat sown area. Mu yield more than six hundred fifty pounds to seven hundred pounds.
