EFFECTS OF DIFFERENT CULTIVATION METHODS UPON THE DEVELOPMENT OF COTTON BOLLS

Shen Yunxia Xu Xuan(.Department of Agronomy)  
The effects of three different cultivation methods such as plastic film covering, transplanting and direct seeding on the development of cotton bolls formed in various periods were studied.Results obtained from the experiment showed that cultivation methods have a little effect on the outer-morphology and the inner physiology change of cotton bolls formed in the same period in the developing process under the contenting of all conditions of cotton bolls development, but cultivation methods have an obvious effect upon the development of each main characteristic of single plant cotton tolls. The ratio of summer cotton boll bearing on cotton cultivated by plastic film is 8% and 14% or so higher than that cultivated by transplanting and direct seeding with the yield of 31% and 60% higher than the both, thus compared with cotton cultivated by transplanting and direct seeding, the plastic film used in cotton cultivation is really a good way to obtain high yield with good quality in cotton production.
