| Abstract: | In this test the gyration method was adopted to obtain the parameters in the experi -ment of three factors, and functional models of unginned and ginned cotton yield, income and prior to frost cotton have been estabished by the obtained parameters. Through the simulation and sieving by computer, comprehensive technic measures have been developed to reach a high yield, top quality and high benefit cotton, which include rational close planting of 3200-3900 plants per mu, 11.3-12.6 kilogram pure nitrogen per mu and top removal from the fruiting branch bearing 14. 5-15. 5 fruits. The main and mutual effects of the tested factors have also been analysed. |
