Abstract

The invention discloses a powder-injection-type fertilization method for siraitia grosvenorii and a preparation method for pollen. The fertilization method comprises the following steps that siraitiagrosvenorii male and female plants are subjected to arrangement cultivation according to a number proportion, the female plants are cultivated on a horizontal rack or a fence rack in a field, and themale plants are cultivated in an arranged greenhouse. After the siraitia grosvenorii male plants enter the flower period, male flowers are taken down in the early morning and brought back to the interior, anthers of the male flowers are cut off and placed in a paper bag or a non-woven bag, the paper bag or the non-woven bag with the siraitia grosvenorii anthers is buried in a drying agent, and drying is conducted at the normal temperature for 24-48 h. The dried anthers are sieved by a 120-mesh or 160-mesh sieve, and the anthers are sieved out. The anthers and ingredients are matched accordingto the proportion of 1:8-1:20, then mixed, shaken up and stored at normal temperature or placed in a refrigerator for storage. In the morning of the flower period of the female plants, the matched anthers are placed in a manual fertilization device or an electric fertilization device, and a spray nozzle of the fertilization device is used for spraying the anthers to stigmas of the siraitia grosvenorii female flowers. The fertilization method saves time and labor, the production efficiency of siraitia grosvenorii can be effectively improved, and the yield of siraitia grosvenorii can be effectively increased.
