Preparation method for pollination pollen

Abstract

The invention discloses a preparation method of pollen for pollination, and belongs to the technical field of pollen collection and preservation. Collected flower buds are crushed and screened to remove impurities to obtain pure anthers, the anthers are fed into a quick-freezing bin to be quickly frozen, the frozen anthers are fed into a drying bin to be sublimated, dehydrated and dried, the driedanthers are cracked to release pollen wrapped in the anthers, and the pollen is separated from the mixture of the pollen and the anthers by using an anther-pollen separator to obtain the pure pollen.The low-temperature freeze drying technology is adopted for the anther, the influence on the biological activity of pollen is small, the activity of the prepared pollen is high, the moisture contentof the prepared pollen is low, the dryness is high, long-time storage is facilitated, and the high activity of the pollen is maintained; the drying speed is high, time is saved, and large-scale industrial production is facilitated.

Description

technical field [0001] The invention discloses a method for preparing pollen used for pollination, and relates to the technical field of pollen collection and preservation. Background technique [0002] Plants bloom and complete pollination to bear fruit. Male flowers produce pollen, and pistils receive pollen to pollinate and bear fruit. Pollination is an indispensable part of plant sexual reproduction and fruit bearing. It has two methods: self-pollination and cross-pollination. Self-pollination refers to the phenomenon that the pollen of this flower falls on the stigma of the pistil of this flower to complete the pollination. A few plants in nature are self-pollinating, such as barley, wheat, soybean, etc. Many fruit trees can also self-pollinate, such as apples, pears, peaches, etc., but usually the rate of self-pollination of fruit trees is very low, or there is no fruit at all. Cross-pollination refers to pollination between different plants, flowers and different c...

Problems solved by technology

Most types of pollen that cannot be used immediately and need to be stored for a long time need a high degree of dryness (water content below 5%) to maintain the activity of pollen during long-term frozen storage. If the moisture content of frozen stored pollen is too high, due to The action of the pollen's own enzymes will significantly reduce the activity of the pollen or even die during storage, and the pollen will lose its use value
