BT Cotton Variety Chuang21Breeding And Cultivation Techniques Research

Cotton is an important economic crop, and fiber crops worldwide, is also China’s important economic crops, the development of cotton production is related to the event in the national economy and people’s livelihood.Gm cotton, less investment, high efficiency, help to increase. Statistical data show that gm cotton can reduce pesticide use, save labor, reduces the production cost. Survey data show that the planting of genetically modified cotton can decrease60%of pesticide use,60-80yuan per mu can reduce pesticide input; Natural enemy populations increased20-40%, ecological benefit is remarkable. Can effectively reduce the labor intensity of farmers, to significantly reduce human and animal poisoning accidents. Using genetically modified cotton can promote the development of cotton production, optimizing the structure of cotton production, cotton industry competition ability, the comprehensive benefit is obvious.This article summarizes transgenic insect-resistant hybrid cotton and Chuang21breeding process, form a complete set of cultivation techniques of exploration and analysis summarizes marketing experience, combined with Biocentury transgenic technology co., LTD. Market practice, puts forward improving cotton market and technology popularization of Suggestions and ideas.1, Overview.Overview of gm cotton and hybrid cotton breeding experience of Chuang21, surrounding the production, and form a complete set of cultivation technique measures are put forward, forming the cultivation discipline of form a complete set. Techniques for demonstration and training for the security and improved varieties and cultivation technique study, implement the seed law together push technical route, reduce production cost, improve the efficiency of the cotton. Through a Chuang21,demonstration, marketing channels, marketing measures concluded marketing experience, learn for other enterprises.2, The breeding of Chuang21. Around the breeding of high-yield, high-quality and high-efficiency goal, the cotton breeding. The hybrid cotton21, with large bell, boll sex strong, good disease resistance, insect resistance, strong good, fertility, yield potential, good quality, wide adaptability, etc; Especially the hybrid cotton21st of transgenic insect-resistant hybrid cotton varieties. Chuang21is the biological technology combined with conventional breeding methods of breeding, high yield, wide comfortable, high quality, with many excellent properties such as resistance to diseases and pests.3, According to the growth and development characteristics of Chuang21, explore in Chuang21growth and development of high efficient cultivation measures to reduce cost, to maximize the potential yield varieties is very necessary. In order to form a complete set of a Chuang21in the Yangtze river basin of cotton high yield and good quality cultivation techniques,2009on the varieties of transplanting density, sowing time, fertilizer application, chemical control, pruning technology is researched. Formed a set of suitable for actual field matching cultivation procedures. Techniques for demonstration and training for the security and improved varieties and cultivation technique study, implement the seed law together push technical route, reduce production cost, improve the efficiency of the cotton.4, Further development of Chinese gm cotton general idea is to promote technology innovation and industrialization ability comprehensively, especially for the industrialization of ability, to cotton enterprises as the main body, which is based on scientific and technological innovation, to property right relations, in laws and regulations, for security, form of cotton industrialization system, cultivate a group of cotton enterprises to participate in international competition. Marketing problem summary, analysis and Chuang21in the experiment and demonstration, marketing channel optimization, marketing measures and other aspects of innovation, so as to get a promotion experience.
