Agarose gel substrate and preparation method thereof

Abstract

The invention discloses an agarose gel substrate and a preparation method thereof. The preparation method comprises the steps that water, agar powder and inorganic salts are mixed, the first mixture is heated and mixed to boiling point, and the agar powder and inorganic salts are dissolved, and a first solution is obtained; the pH value of the first solution is regulated, the first solution is poured in a container, after the bubbles are removed, the solution is cooled at room temperature to solid gel like, and a first nutrition layer is obtained; water and agar powder are mixed, the second mixture is heated and mixed to agar powder and dissolved, and a second solution is obtained; the pH-value of the second solution is adjusted; the second solution is cooled at room temperature and poured on the first nutrition layer, after the bubbles are removed, the solution is continued being cooled to a solid gel shape at room temperature, and a second nutrition layer is obtained. The obtained agarose gel substrate is used for the soilless culture of plants, with the substrate being not splashing, the users can view through the substrate the cultivated plant roots, the watering cycle is flexible without having to constantly add or replace nutrients, and user experience is improved, and the agarose gel substrate has the characteristics of being repeatedly reusable, nontoxic and low in cost.

Description

technical field [0001] The invention relates to the technical field of plant soilless cultivation, in particular to an agarose gel matrix and a preparation method thereof. Background technique [0002] Potted plants are widely used in daily life as interior decoration. In order to allow plants to grow better, it is usually necessary to add culture substrates to potted plants. From the type of culture substrates, potted plants are generally divided into two categories: traditional soil cultivation and soilless cultivation. Among them, soilless cultivation is mainly Refers to directly cultivating potted plants with nutrient solution, which has the disadvantages of frequent replenishment or replacement of nutrient solution, and easy spillage of the liquid. [0003] In recent years, gel substrates have been gradually applied to the field of soilless cultivation of potted plants, usually polyacrylamide gel or superabsorbent resin gel particles are used as transparent cultivation...

AI Technical Summary

Problems solved by technology

Therefore, neither the polyacrylamide gel matrix nor the superabsorbent resin gel matrix is ​​suitable for potted plants, and the use range is narrow
