３ａ试验结果表明：在早稻收割后再种一季棉花（简称稻茬棉）是完全可行的。但必须注意解决好三个问题：一是选用早熟品种，以“中棉１４”、“中棉１６”为宜；二是提早播种期，播期一定要在６月１２日以前；三是进行早熟栽培，采用大容器培育大壮苗，做到带蕾移栽。生产实践证明：肥－稻－棉三熟制，是调整江南双季稻区种植业结构、解决糖棉争地矛盾、改良土壤理化性状的切实可行的一种新的耕作制度。 3a test results show that: in the early rice after reaping a quarter of cotton (referred to as rice stubble cotton) is entirely feasible. But we must pay attention to solve three problems: First, the choice of precocious varieties to “cotton” 14, “cotton 16” is appropriate; the second is the early sowing date, sowing date must be before June 12; the third is to Precocious cultivation, using large containers to grow big strong seedlings, so that buds with transplanting. Production practice has proved that the fertilizer-rice-cotton-three-cropping system is a new farming system that can adjust the planting structure in double-cropping rice in Jiangnan, solve the contradiction between sugar and cotton and improve soil physical and chemical properties.
