Problems solved by technology

[0005] However, in the actual seedling raising process, the amount of water replenishment is often determined by the experience of seedling raising workers, and there are often not many people with little experience in production, and it does not meet the requirements of standardized plug seedling production in the future.

Embodiment 1

[0025] A method for accurately replenishing water to a substrate, comprising the following steps:

[0026] (1) Select the target matrix and measure the maximum water content of the matrix. The upper limit of hydration of the substrate is the maximum water content of the substrate.

[0027] (2) Dry in the shade at room temperature. Measure the moisture content of the matrix with a speed tester every day until the moisture content does not change for three consecutive days.

[0028] (3) Take a certain amount of substrate, put the substrate in a naturally loose state into the hole tray, and scrape it flat. The initial data of the moisture content of the matrix was collected with a speed tester and repeated three times.

[0029] (4) Pour all the matrix into the container, add water to the matrix in proportion according to the volume of the matrix, and mix well. Put the loose substrate into the tray again and scrape it evenly. Then use the speed measuring instrument to collect...

Embodiment 2

[0034] According to embodiment 1, setting substrate is vermicompost substrate, and the hole plate specification is that depth is 62mm, and hole bottom width is 38mm, and hole volume is 125mm 3 . Take the vermicompost matrix with the volume of 10 holes, the volume is 1250mm 3 . Add 50ml of water each time, mix well and put it into the hole tray evenly. The moisture content of the matrix is ​​measured with a speed measuring instrument and brought into the exponential model.

[0035] which yields the following result:

[0036] Table 1

[0037]

[0038] Bring the data in Table 1 into the model to get the formula:

[0039] y=6.9184e 0.0633x

[0040] R 2 =0.998

[0041] verify:

[0042] (1) Randomly take the matrix and put it into the hole tray, and scrape it flat.

[0043] (2) Each hole is a treatment, repeated three times. Set the preset matrix moisture content of treatment Ⅰ.Ⅱ.Ⅲ. to 20%, 30% and 40% respectively.

[0044] (3) Measure the moisture content of the ma...

Abstract

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.

Description

technical field [0001] The invention relates to the field of plug seedling cultivation, in particular to a method for accurately replenishing water to a substrate. Background technique [0002] In recent years, the plug seedling industry has developed rapidly, gradually developing towards scale, intensification, standardization and industrialization. The plug seedling raising technology saves seeds, has low production cost and high degree of mechanization, which greatly improves production efficiency. [0003] The most important work in the seedling production process of plug seedling cultivation is water management, which requires the substrate to have suitable humidity, and the seedling cultivation substrate must have certain air permeability and water retention. Neither can the humidity of the tray matrix be very small, which cannot meet the needs of seedling growth and development; on the contrary, if the moisture in the matrix is ​​too saturated and the humidity is too...
