江苏盐城沿海棉区的棉花、旱粮、绿肥间套作,已成为现阶段的主要耕作制度。 在较好的种植与管理水平下,绿肥、棉花一熟可亩产皮棉100—150斤左右;麦、绿肥、棉两熟间套作可亩产皮棉100—150斤,大麦300—400斤;麦、绿、棉、玉米三熟间套作可亩产皮棉100斤左右、大麦350斤左右、玉米400斤左右。棉麦两熟间套作较一熟棉花在棉产不减少的前提下可增产大麦300—400斤。棉花、玉米由于夹种比例不同,据试验以一亩纯作棉花亩产皮棉150.1斤和一亩纯作玉米亩产615斤的产量与两亩棉花、玉米间套作的产量
Yancheng coastal cotton area of Jiangsu cotton, dry grain, green manure suite, has become the main farming system at this stage. Under better planting and management level, green manure and cotton one-crop yield 100-150 jin of lint per mu; wheat, green manure and cotton intercropping can produce 100-150 jin of murable lint and 300-400 kg of barley; Wheat, green, cotton, maize intercropping sets per mu lint 100 pounds, about 350 pounds of barley, 400 kg of corn. Two sets of cotton and wheat intercropping than the more mature cotton production in cotton does not reduce the premise can increase barley 300-400 pounds. Cotton, corn as a result of the different types of folders, according to the experiment to a mu of pure cotton yield 150.1 kg of lint and a mu of pure corn yield of 615 kg and two acres of cotton, corn intercropping production
