在全国农业学大寨、普及大寨县群众运动的推动下,1976年我室种丰产地1亩,亩产干粒早造1,140斤,晚造879斤,年产2,019斤。技术措施是: 深耕改土施足基肥毛主席说:“深耕是个大水库,大肥料库,否则水、肥再多也不行。”土壤耕作层是蓄水保肥和作物根系生长活动的场所,耕作层的深浅直接关系到玉米生育的好坏和产量的高低。我所丰产地活土层原只有5寸左右,1975年12月中旬,采用局部深耕的方法深耕播种沟,沟宽1.5尺,深耕0.8—1尺,
Under the impetus of the Dazhai Agricultural Science and popularization of the mass movement in Dazhai County, in 1976, 1 mu of cultivated land was produced in our country with a yield of 1,140 kg of dry grain per mu as early as 879 kg and an annual output of 2,019 kg. The technical measures are as follows: Farmers plowing the foundation and applying fertilizer Feishui Chairman said: “Deep plowing is a large reservoir, a large fertilizer library, otherwise water and fertilizer will not do more.” Soil tillage layer is water and fertilizer and crop root growth activities of the place, The depth of farming layer is directly related to the quality of corn and the level of yield. The original soil layer of my high yield was only about 5 inches. In mid-December 1975, the method of partial deep plowing was used to cultivate sowing ditches with a width of 1.5 feet and a depth of 0.8-1 feet.
