A kind of Sichuan alder male inflorescence fast drying and pollen efficient collection method

Abstract

The invention discloses alnus cremastogyne staminate inflorescence quick drying and efficient pollen collecting method. The method includes the following steps of inflorescence collecting, wherein alnus cremastogyne staminate inflorescence 4-5 cm long is collected; assembling an inflorescence drying frame; inflorescence placing, wherein the collected staminate inflorescence 4-5 cm long is laid on parchment of the A-type drying frame; controlling the environment of an inflorescence drying room, wherein the indoor humidity is required to be smaller than 40%, and the temperature is within the range of 25-28 DEG C; releasing and drying pollen, wherein all pollen is released within 2-4 days, and the released pollen is naturally dried within 12 h; collecting the pollen, wherein the drying frame is moved out of the drying room and put in a windless room; storing the pollen, wherein the pollen is put into a refrigerator at the temperature of 4 DEG C. The alnus cremastogyne staminate inflorescence is processed through the method, and the inflorescence drying speed can be increased; the obtained pollen is high in dryness and small in water content and does not cake or mildew during long-term storage.

Description

technical field [0001] The invention relates to a method for drying inflorescences and collecting pollen, in particular to a method for quickly drying male inflorescences of Sichuan alder and collecting pollen efficiently. Background technique [0002] Sichuan alder (Alnus cremastogyne Burli) is an arbor of the genus Alnus in the Betaceae family. It is naturally distributed in the Sichuan Basin, northern Guizhou, southern Shaanxi, and southeastern Gansu. At the same time, Hunan and Fujian have also been introduced and cultivated on a large scale. Sichuan alder grows rapidly, has a well-developed root system and can fix nitrogen. It likes humidity and is resistant to barrenness. The material is light and soft, and its hardness is moderate. [0003] Sichuan Alder is monoecious, and the female and male flowers are catkin inflorescences, and both female and male flowers bloom in spring. In the middle and early March of each year, the male flowers develop first, and the catkins ...
