Studied On The Distribution Of Different Fruiting Branch Fibre Quality In Ccri 63 Cotton

The test on CCRI 63 is designed for studying the yielding, quality construction features, ensuring the optimal bolling positions and time so as to obtain optimized cultivation technique formula as well as high output and high quality. This test makes comparative analysis for different fruiting branch fiber quality of CCRI 63 of insect-resistant hybrid cotton, determining 8 quality indexes of fiber upper part like average length, Micron value, fracture ratio strength, spinning average index, uniformity, yellowness, etc. By index weighted and comprehensive analysis, the research makes sure of the distribution under the weather of Hunan province in 2009 and the cultivation technique system. The results showed that:except reflectivity, the 8 fiber quality indexes are different, and the fruiting branch of cotton tree upper part bears the best cotton bolls fiber quality.
