The test in 2010 in the Tarim Basin in Xinjiang University Agriculture Experiment Station cotton varieties tested the for hybrid cotton Mega study both transplanting cotton in different density population quality quality indicators, the results are as follows: 1, transplanting cotton groups height, stem diameter, the amount of fruit section, fruiting branches amount showed a \after July 15. Plug transplanting cotton processing differences than bare root transplanting cotton obvious. Larger differences between each trait period after June 10, after June 10, the time period is a critical period of reasonable regulation of population groups traits. 2, transplanting density affect transplanted of Mian Mian strains traits important factors the plug seedlings transplanting cotton has more than bare root seedling transplanting cotton leafy shoots number tendency. On different types of transplanting transplanting cotton production mainly by leafy shoots quantity leafy shoots boll number, fruiting branch boll number and fruiting branches average boll weight influence fruiting branch boll number is the main body of the transplanting of cotton production, the leafy shoots bells and leafy shoots bell weight role in promoting increased production. Transplanting cotton yield improvement is to give full play to the leafy shoots while stable fruiting branches yield advantage, leafy shoots into the bell. 3, transplanting Mianmian bell space lateral distribution mainly inner circumference, two-bit, reduced the boll peripheral distribution with the density of the third quarter bit corresponding increase in; boll longitudinal mainly concentrated in the central section, Plug shift planted Mianmian bell section concentrated than bare root seedling transplanting cotton, two types of transplanted cotton showed the tendency of the upper section into bell low. 4, the density of 45,000 / hm 2 pm bare root cotton and Plug cotton plant high volume of fruit section showed a linear relationship with yield, indicating that for the transplanting cotton purposes of: 45000 / hm ~~ 2 density low to obtain high-yield, should give full play to the yield potential of the individual. 5, the density of 90,000 / hm ~ 2,13.5 ten thousand / ha to 2 pm, and yield, plant height, the amount of fruit section, section sticks than quadratic function. Transplanting cotton groups suitable for plant height: 90,000 bare-root / hm ~ 2 is about 65.5cm, bare root 135000 / hm ~ 2 62.8cm about 90,000 plug / hm ~ 2 is about 70cm, hole disk 135000 / hm ~ 2 is about 65cm; groups the Fruit Festival quantity: bare root 90000 / hm ~~ 2 3065000 / hm ~~ 2, 135,000 bare-root / hm ~~ 2 3580000 / hm 2, Plug 90,000 / ha to 3.44 million / ha, Plug 135,000 / ha to 4.544 million / hm ~ 2; groups section sticks optimal value: bare root of 45,000 / ha to 3.26, bare root 90000 / hm 2 2.67 135,000 bare-root / hm ~ 2 2.51 Plug 45000 / hm ~ 2 3.35, Plug plants / ha ~~ 2 3.1, Plug 135000 / hm ~ 2 2.97.
