Immersing type pressure change sprouting promotion soakage method

Abstract

A soaking-type atmospheric pressure variable method for promoting germination and soakage comprises the following steps: firstly, selecting a proper amount of seeds and a pressure container and pouring water and the seeds into the container, so that the seeds are soaked in the water; secondly, reducing the pressure in the container in an atmospheric-pressure variable manner to extract air inside the container and in the seed coats and the seed cavities, so that the container and the seeds are in a negative-pressure state; and releasing pressure in the container, wherein the seeds can rapidly absorb water in the pressure releasing process and the soakage of the seeds can be achieved when the seeds absorb the water. By adopting the atmospheric-pressure variable manner, the method allows the seeds with coat mechanical disturbance to achieve the rapid soakage in a short time so as to make enzyme inside the seeds work, so that the embryo tissue in the seeds has high metabolic activity and the embryo can be rapidly divided and germinate.

Description

technical field [0001] The invention relates to a method for soaking seeds, in particular to a method for promoting germination in which seeds are quickly soaked in a short time by means of variable air pressure. Background technique [0002] Before the seeds are sown, soak the seeds in water to make them fully soaked, then drain the water, and immediately sow or germinate the seeds. This is a good measure to promote the water absorption of the seeds and avoid too slow water absorption in the soil, or extremely irregular seed water absorption and germination due to environmental differences. [0003] Before infiltrating dormant seeds with mechanical barriers in the seed coat, in order to allow the seeds to absorb water effectively, the seed coat will be corroded, cut, worn, partially or completely removed, so that the seed coat can inhibit germination. decrease or disappear. There are many methods of seed coat treatment for hard seeds (those that do not absorb water after ...

AI Technical Summary

Problems solved by technology

[0008] Due to the risk of overtreatment in the above-mentioned seed germination promotion methods, such as cutting marks, excessive friction, improper control of chemical agents and water temperature, it is easy to damage the embryo and endosperm of the seed

Moreover, the operator is vulnerable to damage from machinery or chemicals when handling improperly.
