| Abstract: | According to the fixed spots observation of the condition of cotton seedling of many years and multi places of Hunan Province and the data on climatic observations, and by using the methods of correlation and regression analysis the inner link and quantitative analysis of cotton yield to the charactors of the condition of seedling and climatic conditions were studied. Key factors which showed influnces on cotton growth and development and yield formation were in- vestigated. Based on the built regression equation, the conditions of seedlings were predicted and forecasted. Thus the effective measures for both promoting and controling plant develop- ment were suggested. It provided scientific foundations for production management and taking macroscopic decisions. |
