位于三川河上游、青龙河两岸、柳林县沿川的李家湾、薛家湾、穆村等社队的农民,充分利用自然资源,坚持科学种田,推广间作套种,农业增产增收,经济效益显著。1983年,尽管气候干旱,但沿川水地仍出现了一批双千田科技户,就是在1亩水地里收到1,000斤粮,获得1,000元钱;有的科技户,1亩地里收入甚至高达2,000元。这些科技户的具体作法可分为三种:第一种,粮菜间作套种。如穆村公社一大队社员贾存富在4分水地里,采用7.5尺一带的带状套种方法,先栽大蒜8行,折合亩留苗15,000株,产蒜110挂,产值220元,蒜苔收入20元;收蒜前一个月在畦内隔2行套种1
The farmers in the communes of Lijiawan, Xuejiawan and Mucun along the upper reaches of the Sanchuan River, the banks of the Qinglonghe River and along the Liulin River in Liulin County make full use of natural resources, insist on scientific farming, promote intercropping, increase production and increase incomes from agriculture, and have remarkable economic benefits . In 1983, despite the arid climate, a number of Shuangqiantian science and technology households still appeared in the rivers along Chuanchuan, receiving 1,000 pounds of grain in 1 mu of water for 1,000 yuan. Some tech-savvy households, or 1 mu of land, earned or even Up to 2,000 yuan. The specific practices of these science and technology households can be divided into three types: first, intercropping intercrops. For example, Jia Cunfu, a member of the Mu Village Commune, used a strip-like intercropping system of 7.5 feet in a 4-point paddy field. He first planted 8 rows of garlic, equivalent to 15,000 mu of seedlings, produced 110 pests of garlic with a production value of 220 yuan and income of 20 Yuan; Garlic harvest a month ago within the interval of 2 intercropping 1
