Method for precisely replenishing water to substrate

The invention relates to a method for precisely replenishing water to a substrate. The method comprises the following steps: airing the substrate in a natural environment; acquiring the initial water content of the substrate by using a quick test device; adding different quantities of water into the substrate, and then, testing the water content of the substrate by using the quick test device; establishing a relation model of water content and water addition quantity of the substrate by using an analogy method based on a dynamic data driven value; and accurately calculating the initial data of the water content of the substrate and the water replenishing quantity required to replenish water until the water content of the substrate is appropriate. The method for precisely replenishing water to the substrate can be used for precisely replenishing water and correctly regulating the humidity of the substrate and has certain guiding significance for standardized and industrialized seedling production. 本发明涉及种给基质精准补
