为了探索我省棉花优质低耗规范化栽培技术,我们于1984～1986年在不同棉区的不同土壤类型的棉田进行了棉花多因子综合农艺措施数学模型的多点多年试验,并借助微机模拟和综合优选,得出若干个规范化栽培的优化方案。1987年进行了反馈试验,验证了优化方案的可行性。在此基础上,综合我省大面积植棉的实际情况,提出适合我省推广的二套模式,即模式一:亩产皮棉100～125公斤以上的栽培技术规范;模式二:亩产皮棉75～100公斤以上的栽培技术规范。一般来说,在平原洲地和水稻土植棉,可选用模式一;在丘陵棉区可选用模式二,较易取得良好的效果。
In order to explore the cotton cultivation technology of low quality and low-loss in our province, we conducted a multi-year and multi-year experiment on the mathematical model of cotton multi-factor agronomy in different soil types in different cotton fields from 1984 to 1986. With computer simulation and synthesis Optimal, come to a number of standardized cultivation optimization program. In 1987, a feedback test was carried out to verify the feasibility of the optimization scheme. On this basis, based on the actual situation of cotton planting in large area in our province, we put forward two sets of models that are suitable for the popularization of our province. The first one is the cultivation technical specifications of 100 ~ 125 kg per mu lint; ~ 100 kilograms of cultivation techniques. In general, in plain and paddy soil cotton planting, the optional mode one; in the hilly cotton area optional mode two, easier to obtain good results.
