榆林地区川水地面积占全区总耕地的10%,每年所产粮食却占总产量的40%左右.干旱、风沙、霜冻,冰雹、洪涝及病虫等是农业生产发展的不利因素.从农业本身来看,浅耕粗作,广种薄收,土壤耕性不良,基本条件差;缺肥则是粮食产量低而不稳的关键因素.尤以大旱之年,川水地的粮食产量普遍下降,近几年,地委领导全区人民狠抓以养猪为中心的农家肥料建设的同时,迅速扩大草木栖面积,积极推行绿肥压青.芦河川水地区推行草木栖绿肥压青后,增产效果非常显著,粮食作物大面积获得高产.如横山县高家坬大队,1971年100亩粘泥水地压青(鲜草约2000斤),谷子平均亩产530斤,比未压青的谷子增产65.5%;横山县梁家湾生产队,1971年50亩水地压青(鲜草2000斤左右),谷子平均亩产620斤,
The area of water and water in Yulin area accounts for 10% of the total cultivated land in the region, but grain produced annually accounts for about 40% of the total output.Drought, wind and sand, frost, hail, floods and pests are the unfavorable factors for the development of agricultural production. In terms of agriculture itself, lack of fertilizer is the key factor in low and unstable grain output, especially in the severe drought year, with the general decline in grain output In recent years, the people’s government of prefectural committees and districts has paid close attention to the construction of fertilizer for farmers centered on raising pigs, and at the same time has rapidly expanded the area of grass and wood habitat and actively promoted the green manure compression. The effect is very significant, a large area of high yield of food crops, such as Hengshan County Gao Jiongtao brigade, 1971 100 acres slime water pressure green (fresh grass about 2000 pounds), millet average yield 530 pounds, millet than unbleached yield 65.5%; Liangshan Bay Hengshan production team in 1971, 50 acres of water pressure green (about 2,000 pounds of fresh grass), millet average yield 620 pounds,
