Yearly 200,000-time cotton seed production method

Abstract

The invention discloses a Yearly 200,000-time cotton seed production method comprising the following steps: 1, variety selection; 2, sowing period: selecting a land in the Hainan Sanya region, whereinthe land is fertile, easy in irrigation and pathogen infection-free; 3, using a ridge culture black mulch film to cover the land; 4, employing a front-stable middle-promotion post-control method to manage according to a cotton winter off-season multiplication concave growing law; 5, heavily dressing a flower boll fertilizer and fully watering a flower boll water in a middle stage cotton flower bud and boll stage and a next year Hainan low temperature stage; 6, controlling watering under the cotton boll growth conditions when the temperature rises in the late state and cottons start to open bolls; 7, harvesting the cottons in March the next year when the cottons open bolls and get ripe; 8, transporting seeds to a south Xinjiang high and stable yield seed production region in Xinjiang, andsowing in April; 9, carrying out green prevention and control for insect pests and weeds; 10, defoliating and ripening in September, and mechanically harvesting in October. The method is feasible, simple in operation, and one kg of seeds can produce 200,000 kg within one full year, thus obtaining 200kg of breeder seeds; by using the seeds prepared in one year, the method can plant 80% of the cotton fields in the whole 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...

Problems solved by technology

In other words, if the seeds of excellent varieties cannot be produced as soon as possible, the promotion of excellent varieties will be limited, and the crystallization of excellent varieties and innovative technologies will not be able to exert due economic and social benefits.
