| 摘 要： | 采用正交旋转回归设计,研究了影响旱地棉花产量构成的密度、肥料、DPC化控三项农艺措施之间的关系。结果表明,在旱地条件下,影响棉花产量的三项农艺措施顺序依次为密度>化控>肥料。此外还研究了三项农艺措施之间的互作效应,并建立了旱地棉花高产模型。最后分析了旱地棉花土壤水分利用率和经济效益。

Optimized Route and High-Yield Model of Dry Land Cotton |
| |
| Abstract: | The relationship among three factors of dryland cotton culture was studied by orthogonal and regression experiment. It showed that the dendensity of cotton was the highest; the nitrogen was second and DPC was low. The optimized model was built and the response and interaction among three factors were studied.In addition,analysis of water efficiency and the economic benefit of dry land cotton were made. |
