棉花叶面施肥研究进展

作物叶面施肥具有许多土壤施肥无法比拟的效果，是补充营养元素和改善品质的一种重要手段。棉花叶面施肥不仅可以解决苗期低温，后期根系活力下降所造成的根系养分吸收不能满足需求的问题，而且可以提高产量改善棉花品质。本研究分析了叶面施肥所能解决的棉花生产中的问题。在前人研究的基础上并结合中国叶面肥的发展趋势，对棉花叶面肥的种类、叶面施肥技术进行了系统的归纳和总结，并对今后棉花叶面专用肥的研究方向进行了展望。

Research Progress on Foliar Fertilizer of Cotton

Compared with soil application, foliar fertilization has a huge advance. And it is a significant method of supplying nutrition and improving variety quality. Foliar fertilization of cotton can solve the problem of insufficient nutrient absorption caused by root activity decreased later. And it can also increase production to improve cotton quality. The cotton foliar fertilizers include nutritional fertilizer, regulative fertilizer, biotype fertilizer and compound fertilizer. This paper introduced the effects of the four types of foliar fertilizers on cotton growth and the methods of fertilizing. In addition, the research prospects on the foliar fertilizers of cotton were put forward.
