棉花专用全价肥的应用研究

Study on the Application of Complete Nutrients Specific Fertilizer for Cotton

为进一步开发棉花专用全价肥的增产效应，在1996年试验基础上，对筛选出的棉肥A进行使用方法研究。试验结果表明，以总肥量40％的N用专用肥作基肥，60％的N用尿素作花铃肥施下，效果更佳，对生长后期遇灾害性气候，棉株的抗逆力增强。

The complete nutrients specific fertilizer A for cotton was selected from experiments conducted in 1996, based on which we continued to study the effect of differen applying methods on output. The results suggested that the best method is to use the fertilizer A as a basic manure which accounts for 40% of the total nitrogen and urea for the other 60% which applied when the plant is flowering and forming young fruits. This could improve the plant resistance to bad weather conditions during the late stage of their development and growth.
