Abstract

The results showed that when summer cotton was sprayed Zn or N+Zn in seedling stage,the root activity , the NR activity of root and leaf ,the chlorophyll contents and photosynthetic rate of cotton leaf increased obviously.The boll number of per plant increased 17.3% and 25.3% respectively than that of CK, and lint cotton yield increased by 18.5% and 24.5% respectively.
