我们队地处高寒山区,冬季低温,春暖迟,寒露风早,过去只种单季中稻,随后发展为稻麦一年两熟。一九七五年冬,在第一次全国农业学大寨会议精神的鼓舞下,我队农科组,进行三熟制试验。这一年,在六亩一分地里进行麦稻稻轮作,一九七六年春收小麦亩产四百四十五斤,早稻亩产一千零八十斤,晚稻亩产五百五十六斤,三熟合计亩产二千零八十一斤,比稻麦两熟增产百分之三十四点六。一九七七年继续试种,在春旱缺水的情况下,三熟仍比两熟增产百分之十七。两年来的试验,使我们体会到在高寒山区搞三熟,主要应抓住选用和搭配好各熟早熟良种,加强施肥管理,确保各熟丰收。 Our team is located in the alpine mountains, cold in winter, late spring, cold dew earlier, in the past only single-season rice, then developed into rice and wheat two crops a year. In the winter of 1975, inspired by the spirit of the First National Agricultural Science Dazhai Conference, our team of agricultural sciences conducted a three-pronged experiment. This year, wheat rotation was carried out on a per-mu basis in six acres. Four thousand forty-five tons of wheat per mu was harvested in the spring of 1976, one hundred and eighty catches of early rice per mu, five hundred and fifty tons of late rice per mu Six pounds, three cooked total of 2,081 kilograms per mu, rice and wheat two crops increased by 34.6%. In 1977, the trial planting was continued. In dry and dry conditions, the three-crop production still increased by 17% over the two-crop. Two years of experimentation made us realize that we should engage in three-cropping in the alpine region. We should mainly seize on the selection and matching of the mature precocious varieties and strengthen the fertilization management to ensure the harvest of all crops.
