Pollen liquid utilizing method for cotton hybrid seeds production

Abstract

The present invention relates to a utilization method of pollen liquor in cotton cross-breeding technique. Said method is characterized by that at the time of making artificial pollination for cotton cross-breeding the pollen can be mixed into liquid culture medium, then the sprayer can be used to spray pollen or the ''specially-made brush'' can be used to apply pollen so as to implement artificial auxiliary pollination. Said method can raise working efficiency by 80%-90%.

Description

technical field [0001] The invention relates to a new method and related technology for using pollen solution for pollination in cotton hybrid seed production. Background technique [0002] Cotton is the largest economic crop in my country. However, my country's cotton yield is low, the quality is unstable, and it lacks international competitiveness. Especially after China's entry into the WTO, a large number of high-quality and low-priced cotton in the world has poured in, and domestic cotton spinning companies have purchased foreign cotton one after another, resulting in a backlog of domestic cotton for several consecutive years. , the threat to domestic cotton production cannot be ignored. [0003] The use of crop heterosis is a very effective way to increase yield and improve quality. It has been widely used in rice, corn, rape and other crops, and has achieved huge economic benefits. Similarly, the improvement of cotton yield and quality also depends on the utilization...

Problems solved by technology

However, cotton hybrid seed production still requires manual assisted pollination. The current methods such as flower-to-flower and casing are time-consuming and labor-intensive. A skilled worker can only obtain about 0.45kg of hybridized seeds per day for assisted pollination under suitable environmental conditions. seed

Due to the high cost of seed production and easy mixing, the promotion speed of hybrids is delayed, and the utilization of hybrid advantages is affected, and the benefits of increasing production and income are difficult to show
