在我省常阴沙农场针对长江下游两熟棉区的特点,于1982年进行了麦套地膜棉花大面积丰产栽培技术试验。该场地处长江下游南岸,沙洲县东北部。年雨量1073毫米,梅、秋季雨水集中,水害严重;年平均气温15.2℃;无霜期200～230天;7～8月间常受台风袭击。试验地为长江冲积沙壤土,地面真高3.8～4.1米(上海吴松零点以上),土壤有机质1.33％,全氮0.083％,速效磷3.98ppm,速效钾23.1ppm。试验田实行“一水三旱”轮作,一年两熟
In our province Changyin Sha farms for the lower reaches of the Yangtze River cotton fields in the two characteristics of the cotton in 1982, a large area of cotton film mulching cultivation techniques. The venue is located on the south bank of the lower reaches of the Yangtze River and northeast of Shazhou County. Annual rainfall of 1073 mm, plum, autumn rainwater concentration, serious water damage; annual average temperature of 15.2 ℃; frost-free period of 200 to 230 days; July to August often hit by a typhoon. The test area is alluvial sandy loam of the Yangtze River. The ground is about 3.8-4.1 meters in height (above the point of Wusong in Shanghai) with 1.33% of soil organic matter, 0.083% of total nitrogen, 3.98ppm of available phosphorus and 23.1ppm of available potassium. Experimental field to implement “a water three dry” rotation, two ripening a year
