Feedback Demonstration of Optimized High-yield Cultivation in Hybrid Cotton

The feedback demonstrations of optimized high yield cultivation for hybrid cotton were conducted at seven sites.The results showed that it had the effects of increasing production and efficiency by increasing planting density appropriately,chemical regulation and scientific use of fertilizers,such as cutting down usage of nitrogen,stabilizing usage of phosphorous,the accuracy of the results of five factors and five levels test and the feasibility for the applications in large area were confirmed.
