刘集公社地形略有起伏,大平小不平。土壤砂性重、透水性强。原来棉花完全用沟灌,水、土、肥流失严重,所以限制了产量的进一步提高。为了改进棉花的灌溉技术,从去年开始了点、面结合的喷灌棉花的试点工作。在点上喷灌与沟灌对比试验中,尽管有些不利因素,仍取得了增产8.4%的良好效果。面上对四百多亩棉田共喷灌了八百余亩次,受到了广大贫下中农的欢迎。喷灌试验点总面积20.65亩,喷灌区13.9亩、沟灌对比区6.75亩,土质均为砂壤土,是一九七二年新
Liu set commune slightly ups and downs, Daping small uneven. Soil sand heavy, strong water permeability. The original full cotton ditch irrigation, water, soil, fertilizer loss serious, so limiting the yield to further improve. In order to improve cotton irrigation technology, starting last year, a combination of the pilot project of sprinkler cotton. Sprinkler irrigation and ditch irrigation at a point contrast test, despite some unfavorable factors, still achieved a yield of 8.4% of the good results. The surface of the four hundred acres of cotton fields sprinkled a total of 800 acres, welcomed by the majority of poor middle peasants. Sprinkler irrigation test point The total area of 20.65 mu, sprinkler irrigation area of 13.9 acres, furrow irrigation contrast zone 6.75 acres, sandy soil are soil, is new in 1972
