Problems solved by technology

Although this type of substrate has a certain water retention capacity, it still cannot provide a stable and good growth environment for the growth of plant roots.
For example, after using for a period of time, the peat and vermiculite in the matrix will become finer and sink due to water impregnation, while the perlite will float to the surface of the matrix, reducing the permeability of the matrix, which will easily cause the matrix to rot and smell over time. affect the growth and development of crops
At the same time, the structure of this kind of matrix is ​​very loose, which is not convenient for the transportation and transplantation of plants.

Embodiment 1

[0036] Weigh 20 parts of bagasse, 15 parts of coconut bagasse, 25 parts of plant straw, 15 parts of walnut shell, 10 parts of perlite and 9 parts of diatomaceous earth for later use. The bagasse, coconut bagasse, plant stalks and walnut shells are respectively crushed to 60 mesh, mixed evenly, watered thoroughly to make the water content of the matrix reach 60%, tightly covered with plastic film, and exposed to the sun for 90 days to complete fermentation. Add perlite and diatomaceous earth, mix evenly, dilute 100 times with 40% formaldehyde solution, spray the mixed matrix, seal the plastic film for 2 days and nights, spread the matrix, expose to the sun until there is no formaldehyde smell, and you can get the desired Soilless cultivation substrate.

Embodiment 2

[0038] Example 1 was repeated with the following differences: 10 parts of bagasse, 10 parts of coconut bagasse, 20 parts of plant straw, 10 parts of walnut shells, 10 parts of perlite and 5 parts of diatomaceous earth were weighed for later use.

Embodiment 3

[0040] Example 1 was repeated with the following differences: 15 parts of bagasse, 20 parts of coconut bagasse, 30 parts of plant straw, 30 parts of walnut shells, 15 parts of perlite and 15 parts of diatomaceous earth were weighed for later use.

Abstract

A matrix for soilless culture is prepared from cane dregs, coconut dregs, straw or stalk, walnut shell, pearlite and diatomite through mixing, pulverizing, fermenting, disinfecting, adding adhesive, foaming agent and sulfurizing agent, further processing and shaping.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation, and in particular relates to a soilless cultivation substrate. Meanwhile, the invention also relates to a preparation method of the matrix. Background technique [0002] Compared with traditional soil cultivation, soilless cultivation technology has the advantages of saving water, saving fertilizer, and avoiding soil pollution. It can be planted in places that could not be cultivated before, such as deserts, islands, roofs, etc., and has received more and more attention. s concern. [0003] As the basis of plant growth, the choice of substrate is particularly critical. Most of the existing soilless culture substrates are based on peat, rock wool, perlite, etc., adding stone sand, stone grains, vermiculite, and fermented and carbonized plant straw, etc., which are obtained after simple mixing. Although this type of substrate has a certain water retention capacity, it still cann...
