Plant culture medium and preparation method and application thereof

Abstract

The invention provides a plant culture medium and a preparation method and application thereof. The medium is prepared from, by weight, 80-90 parts of paper pulp, 20-25 parts of organic fertilizer, 10-15 parts of egg shell powder, 20-40 parts of turf, 30-60 parts of vermiculite, 1-3 parts of preservative and 0.5-1 part of growth regulator. The preparation method includes the following steps that water is added into paper or waste paper, pulping is carried out, and the paper pulp is prepared; the organic fertilizer is produced from animal waste and straw or green grass through intermediate-temperature anaerobic fermentation or aerobic fermentation; the organic fertilizer, the preservative, the egg shell powder, the turf, the vermiculite and the growth regulator are added into the paper pulp, the materials are stirred to be uniform and then dehydrated, microwave sterilization and drying or drying in the sun are carried out, and the plant culture medium is obtained. It is guaranteed that uniform moisture of the medium is kept for a long time, the growth regulator is added, plants can rapidly grow and have excellent quality, it is guaranteed that the medium is not likely to rot through the preservative, and it is guaranteed that the roots of the plants grow healthily.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a plant cultivation substrate and a preparation method and application thereof. Background technique [0002] Solid substrate is a soilless cultivation method that fixes the plant root system with a solid substrate and absorbs nutrient solution and oxygen through the substrate. There are many types of substrates, commonly used inorganic substrates include vermiculite, perlite, rock wool, sand, polyurethane, etc.; organic substrates include peat, rice husk charcoal, bark, etc. Therefore, substrate cultivation is divided into rock wool cultivation, sand cultivation and so on. The nutrient solution is supplied by drip irrigation. The advantage is that the equipment is simpler and the production cost is lower. But it needs a lot of substrates, and the old substrates for continuous cropping are easy to carry germs and spread diseases. Vegetable substrate cult...

Problems solved by technology

In view of the current situation of excessive one-time investment in substrate cultivation facilities, cumbersome nutrient solution management, and difficulty in controlling disease occurrence, we have carried out years of improvement, experimentation, demonstration and promotion of substrate cultivation based on the principles of "simplification, energy saving, high efficiency, and ecology". , to explore a "five reforms" simple organic ecological substrate cultivation technology that can be adopted by the majority of vegetable farmers and is easy to popularize and apply

[0004] The prior art, for example, Chinese Invention Authorized Patent Document, Authorized Notice No. CN 102391039 B, this invention discloses a flower nursery stock cultivation substrate, which consists of the following components by weight as raw materials, straw 14-16, corn cob 11-13 , sorghum husk 7-9, sawdust 7-9, Tenebrio molitor dung 6-8, perlite 4-6, medical stone 4-6, first prepare the above ingredients into a dry matrix, and then mix with the cultured probiotics liquid Fermented together, the invention makes the waste produced in the agricultural and forestry production process into a cultivation substrate suitable for cultivating flowers and seedlings. It has been proved by experiments that it has the same or even better cultivation effect with peat as the substrate, which proves the invention The cultivation medium of flower seedlings can completely replace peat. This invention adapts measures to local conditions, utilizes a large amount of agricultural and forestry waste resources, and develops a clean and environmentally friendly substrate with low production cost and recyclable use. The contradiction between the total amount of depleted peat resources, but the substrate still has room for improvement in terms of regulating plant growth and plant quality
