江苏是我国重要的粮棉生产省。1679～1988年的10年中,粮食作物中的水稻栽插面积年均为3700多万亩,单产400千克左右。棉花900多万亩,单产约55千克,生产力水平较高。但是,各县(市)间的稻棉生产力水平有很大差异,而且棉花的地区差异更大。目前全省水稻、棉花区域布局尚未充分发挥各地优势作物的先导作用,土地资源的 Jiangsu is an important grain and cotton production province in China. During the 10 years from 1679 to 1988, the annual planting area of ​​rice in food crops was more than 3700 mu with a yield of about 400 kg per year. More than 900 million acres of cotton, yield about 55 kg, a higher level of productivity. However, the level of rice-cotton productivity varies widely across counties (cities), and there is greater regional disparities in cotton. At present, the province’s rice, cotton regional distribution has not yet give full play to the leading role of the dominant crops around the land resources
