A method for cotton seed production with annual 200,000 times

Abstract

The invention discloses a method for cotton seed production with an annual rate of 200,000 times. The steps are: 1. selection of varieties; Ridge cultivation with black plastic film covering; 4. According to the concave growth pattern of cotton in winter in the south, adopt the management method of stability, promotion, and control: 5. In the mid-term bud flower and boll stage and the low temperature stage in Hainan in the next year, reapply flower boll fertilizer and water flower boll water; 6. As the temperature rises in the later period, the cotton begins to open bolls, and watering is controlled under the development of cotton bolls; 7. The cotton is harvested after the cotton bolls are opened and matured in March of the following year; 8. The seeds are transported to the high-yield and stable-yield breeding area in southern Xinjiang for sowing in April 9. Green prevention and control of diseases, insect pests and weeds; 10. Defoliation and ripening in September, and mechanized harvesting in October. The method is easy to operate and easy to operate. Within one year, 200,000 kg of seeds can be produced from 1 kg of seeds, and 200 kg of breeder seeds can be obtained. The seeds produced within one year can be used to plant more than 80% of the cotton fields in the country.

Description

technical field

[0001] The invention belongs to the technical field of seed production, and more specifically relates to a method for making (producing) seeds of 200,000 times cotton per year. Background technique

[0002] Cotton is an important material related to the national economy and the people's livelihood, and is the main raw material for the textile industry. Excellent varieties are the internal cause of high-quality and high-yield cotton, and the genetic stability of their excellent traits makes excellent varieties play an important role in cotton production. According to statistics, among the many factors that increase yield, the actual contribution rate of variety improvement to yield increase has reached more than 30%. . Therefore, popularizing cotton fine varieties is a key technology for cotton production. However, in order for good varieties to play their due role, two basic links must be passed: one is to breed the variety, and the other is to plant and a...
