Abstract
The growing habits and single cultivation technique of many transgenic cotton varieties have been reported, but the integrated techniques aimed at one transgenic cotton variety was reported very few. In this study the key cultivation techniques of double-transgenic cotton variety, CCRI 41, were studied in both one maturity and intercropping system in 2004-2005 by use of best regression design and D-saturation design aimed at the growth and development characters and growing patterns and insect control. The growing rate of CCRI 41 is slower in early and middle development stages compared with that of CCRI 23, but faster from flowering stage on. The main cultivation techniques of CCRI 41 in the Yellow River Valley at 1350～1500 kg·hm -2 yield potential are: planting density is 52500～60000 plants·hm -2,pure nutrition dosage is 259.5～300 kg·hm -2,P2O5 8.59～11.36 kg·hm -2,K2O is 6.71~8.72 kg·hm -2. The suitable DPC dosage is 60～75 g·hm -2 in whole season. There are not significant differences in bollworm eggs between CCRI 41 field and conventional cotton, CCRI 23 field, but the number of bollworm lava in CCRI 41 field is fewer significantly compared with conventional cotton field, indicated the perfect bollworm control effect. The bollworm control should do according to control threshold in late growing season. There are not significant differences for other insects and natural enemies between both fields, indicated that other insect control techniques in transgenic cotton field are similar to that in conventional cotton field. The test of main insect control and cost analysis reviewed that the control cost in CCRI 41 field in growing season is 44.39% lower compared with conventional cotton field. The plant bug chemical control test reviewed that the 500 times Endosulfan solution spray is best effective.
