影响我区小麦产量低而不稳的因素是多方面的,而干旱却是关键的因素。为了解决这个问题,我们在庆阳县董志公社南庙大队进行了大面积机深耕和冬、春碾耱保墒试验示范。这项工作已进行了两年。南庙大队前几年集体种植小麦4000多亩,伏耕时用拖拉机深耕的占90％以上。1980年秋播冬小麦3495亩,入冬后土壤表层疏松干旱。针对这种情况,我们动员群众于11月中旬用石滚子碾压1540亩,占麦田面积44.1％,老庄、南庄、西庄三个队冬前碾压面积
The factors that affect the low and unstable wheat yield in our region are many and the drought is the key factor. In order to solve this problem, we conducted a large-scale deep plowing and winter and spring grinding and moisture conservation experiments in the Nanmiao Brigade, Dongzhi Commune, Qingyang County. This work has been going on for two years. South Temple brigade a few years ago collectively planted more than 4,000 acres of wheat, deep plowing with tractors plowing accounted for more than 90%. In the autumn of 1980, 3495 mu of winter wheat was sowed, and the soil surface became loose and dry after winter. In response to this situation, we mobilize the masses in mid-November with roller rolling 1540 acres, accounting for 44.1% of the wheat field area, Laozhuang, Nanzhuang, Xizhuang three teams winter rolling area
