Characteristics of Growing & Development and Yield of Transplanting Cotton after Winter Wheat Harvest in Different Seedling Ways
Abstract: Under field condition, the characteristics of growing & development and yield of cotton over various seedling ways were studied after winter wheat harvest. The results indicated that the development progress, yield components, seed cotton yield and the pre-frost seed cotton yield of transplanting cotton were almost same both under the traditional nutritional bowl grow seedlings after winter wheat harvest and under the technique of factory mutual aid grow seedlings. Compared with the treatment of direct-seeding, budding period and flowering period 26 - 28 d earlier, boll opening stage 26 - 27 d earlier, effective boll setting period prolonged 27 - 28 d, boll number per plant increased by 35.5% - 35.5%, high-quality boll number (the boll in Summer dog days + early autumn boll) increased by 74% - 80.3%, the average bell weight increased by 15.4% - 5.4%, un-ginned cotton yield significantly increased by 39.5% - 41.7%, the unginned cotton yield before frost significantly improved 79.75% - 80.5%, the flower proportion before frost was 86.4% - 86.6% (increased by nearly 20 percentages). Meanwhile, the technique of the cotton factory mutual aid grow seedlings with wheat in same hole has realized specification, commercialization and large scale grow seeding, which favor the cotton mechanized transplanting, completely replace traditional nutritional bowl grow seedlings, promote the development of mechanized transplanting cotton, stabilize cotton production, and realize the double high yields of wheat-cotton double cropping system.
