我省棉田面积约500万亩,在全国居第六位,在南方八省市中占第三位,是主要产棉省之一.我省棉田按自然区划分为淮北平原棉区、江淮丘陵棉区和沿江棉区.这三大棉区的管理水平、耕作制度以及产量等方面都有明显的差异. 首先从产量来看,近十年(1970—1979年) 的皮棉平均单产,沿江棉区为81.27斤,比江淮丘陵棉区的41.41斤高近一倍,产量高低差距较大. 再从耕作制度来看,淮北与江淮丘陵棉区多是一年一熟制,不能充分发挥土地
Our province has an area of about 5000000 acres of cotton fields, sixth in the country, third in the eight provinces in the south, is one of the major cotton producing provinces. According to the natural area of our province is divided into Huaibei plain cotton area, Jianghuai hills Cotton area and the Yanjiang cotton area.The management level, farming system and yield of the three major cotton areas have obvious differences.Firstly, from the perspective of output, the average yield of lint in the recent ten years (1970-1979) Area is 81.27 jin, which is nearly double that of 41.41 jin in Jianghuang hilly cotton area, with a big difference in production level.According to the farming system, most of the cotton area in Huaibei and Jianghuai hilly area is cooked in one year, and can not give full play to land
