A kind of method of dragon fruit pollination

Abstract

The invention belongs to the technical field of fruit tree cultivation, and particularly relates to a pitaya pollination method. The pollination method comprises the following steps: (1) storing pollen, namely collecting pitaya pollen, evenly spraying medicinal alcohol on the pollen surface, carrying out irradiation under an ultraviolet lamp, and carrying out freeze drying until the moisture content of the pitaya pollen is lower than 3%, and storing the pitaya pollen in a shady, cool and dry environment which is not higher than 20 DEG C; (2) preparing pollen suspension, namely taking out the dry pitaya pollen to prepare a pitaya pollen suspension; and (3) carrying out artificial pollination, namely spraying the pitaya pollen suspension on an opposite stigma in the pitaya flowering phase. The pitaya pollination method has the characteristics that the dry product is low in moisture content and free of harmful microorganisms; the product is loose, has excellent reconstitution property and convenient storage condition, and can be used and circulated on a large scale; the suspension is stable after pollen is prepared; the pollen is evenly dispersed and does not easily generate a sediment; the parameters in various steps are controllable; and mass production standard operation can be achieved.

Description

【Technical field】 [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a method for pollination of dragon fruit. 【Background technique】 [0002] Pitaya is a perennial climbing plant of the cactus family (Cactaceae), also known as red dragon fruit, green dragon fruit, fairy honey fruit, lover fruit, etc. Pitaya is native to Central and South America. It is a tropical fruit that is edible and ornamental. It was introduced to Taiwan in the 1990s. In recent years, it has been introduced to Guangxi, Guangdong, Fujian, Guizhou and other provinces and regions. Some provinces have also successfully planted in greenhouses. Studies have found that dragon fruit is a health food with high vitamins, low sugar, and low fat. Its fruits, stems, and flowers have certain nutritional components and health care values. Pitaya fruit has the effects of detoxification, nourishing the lungs, beautifying the skin, and improving eyesight. It is ...

Problems solved by technology

[0006] The purpose of the invention of the present invention is: the pollen storage method in the current prior art is relatively simple, just dry and remove moisture after simple impurity removal, store in a vessel containing a desiccator, the storage is harsh, and there is no maximum pollen preparation process. The problem of preserving the activity of pollen to a certain extent provides a method for pollination of dragon fruit, which has the advantages of low water content in dried products, no harmful microorganisms, loose product with excellent rehydration, convenient storage conditions, and can be used in a large range of circulation. The suspension after pollen preparation Stable, evenly dispersed pollen is not easy to produce precipitation, and the parameters of each step are controllable, which can realize standardized mass production operations, which is conducive to standardized planting of pitaya
