西瓜塑料薄膜双覆盖栽培是在“阳畦育苗,小拱棚定植”的基础上发展起来的新技术,具有省工、省料、效果好、工序简便、经济效益高等优点。我县城关镇种植1300亩薄膜双覆盖栽培的西瓜,比常规栽培的增产38—54%,收入增加53.5—112.4%。实践证明,西瓜塑料薄膜双覆盖栽培是既高产又增收的技术措施。一、冬前准备选地、造墒、施底肥和整地做畦等工作应在冬前进行。好处是:①充分利用农闲季节;②可杀死越冬病菌、虫蛹和虫卵,降低病虫基数;③有利有机肥料发酵分解;④有利增温、保墒,适时播种。1.选地。选择地势平坦、水肥条件较好的偏沙性两合土为好。前茬以禾本科的玉米、谷子等最好:其次是病害轻的棉花和红薯茬;老菜地和八年内种过西瓜的地块不宜选用。
The double covering cultivation of watermelon plastic film is a new technology developed on the basis of “Yangzhu nursery, small arch planting”. It has the advantages of saving labor, saving materials, good effect, simple procedure and high economic benefits. Chengguan Town, my county planted 1,300 acres of film double-covered cultivation of watermelon, 38-54% increase over conventional cultivation, income increased 53.5-112.4%. Practice has proved that watermelon plastic film double-covered cultivation is both high yield and income technical measures. First, preparation for winter pre-election, making moisture, base fertilizer and soil preparation and other work should be done before winter. The benefits are: ① full use of slack season; ② can kill overwintering germs, pupae and eggs, reduce pests and insect pests; ③ favorable organic fertilizer fermentation decomposition; ④ favorable warming, moisture, timely sowing. 1. Choose the place. Select the flat topography, good conditions of water and fertilizer partial sand two loam as well. Preceding to gramineous corn, millet and other best: followed by disease light cotton and sweet potato stubble; old vegetable and eight years planted watermelon plots should not be selected.
