Effect of Density on Yield and Quality in Hybrid Cotton

The process of birth,properties of yield and quality were studied.The results showed that the process of birth was postponed slightly when the density increased.In addition,and when single weight and bolls per plant decreased,and lint percentage was relatively stable,and bolls of hectare and quality were the first two positions of 30 thousand plants per hectare and 39 thousand plants per hectare,and yield was the first position of 30 thousand plants per hectard.It advised that the density increased necessarily in future and advanced channel of increase density.
