A kind of liquid pollination method of Amomum vulgaris

Abstract

The invention relates to the technical field of production of Chinese medicinal materials, and specifically discloses a method for liquid pollination of Amomum vulgaris. The specific steps are: preparing a pollen nutrient solution, and the pollen nutrient solution is composed of the following raw materials in mass percentage: 12-18% sucrose, 0.01-0.02% boric acid , 0.03 ~ 0.05% calcium nitrate, the rest are plant-derived glue, and the plant-derived glue is put into the wall breaker by 5-15 parts of fresh stems of Dendrobium officinale and 1,000 parts of clear water, and is filtered to remove the residue to obtain; then the collected The pollen was added to the pollen nutrient solution to prepare a pollen concentration of 0.6-0.8g / L, and the pollination was carried out during the flowering period of Amomum vulgaris. The liquid pollination method of the invention overcomes the problems of poor pollination and low fruit setting rate caused by factors such as lack of flowering period and few pollinating insects, and improves the pollination seed setting rate and the fruit quality of Amomum vulgaris.

Description

technical field [0001] The invention belongs to the technical field of production of traditional Chinese medicinal materials, in particular to a liquid pollination method of Amomum vulgaris. Background technique [0002] Amomum chinensis is a bisexual flower, which is a normal cross-pollination plant, which can be self-pollination and fruit-bearing, or cross-pollination. Due to the special morphological structure of the flower, the pistil is higher than the stamen, the anther of the stamen is below the stigma of the pistil, the drug column of the pistil is embedded in the grooves of the two drug chambers, the stigma is slightly higher than the anther, and the pollen is difficult to fall on the stigma There are thorn-like protrusions on the surface of the pollen, which are easy to stick to each other and form a group, which is not easy to spread, and the pollination is blocked, so it is difficult to self-pollinate. Only with the help of external pollinators such as insects ca...

AI Technical Summary

Problems solved by technology

Due to the special shape and structure of the flower, the pistil is higher than the stamen, the anther of the stamen is below the stigma of the pistil, and the herb of the pistil is embedded in the groove of the two chambers, the stigma is slightly higher than the anther, and it is difficult for pollen to fall on the stigma , there are thorn-like protrusions on the surface of pollen, which are easy to stick to each other and difficult to disperse, and pollination is hindered, so it is difficult to self-pollinate. Amomum often appears flowers but not real or not many, the natural fruiting rate is only 3-8%, the output is low, it is difficult to meet the needs of production

The use of artificial assisted pollination in production can improve the pollination rate of Amomum edulis. At present, the methods of artificial pollination of Amomum edulis include push-pull method and smearing method. These pollination methods have defects such as time-consuming, labor-intensive, low efficiency, and easy to damage flowers.

[0003] Liquid pollination is a new type of pollination technology. It has the characteristics of fast pollination speed and labor saving. It can increase the water and nutrition of stigma and prolong the time of stigma pollination and fertilization. There are also some problems in liquid pollination technology, such as the ability of pollen to suspend in nutrient solution. Poor, easy to form agglomerates, uneven dispersion, swelling and death in nutrient solution, etc.

At present, liquid pollination has been applied to some fruit trees such as pear trees, kiwi trees and other crops, but there is no literature report on the application of liquid pollination to Amomum yangchun
