Abstract

The invention discloses an environment-friendly lightweight nutrition matrix for soilless cultivation and a preparation method thereof, belonging to the field of planting in agriculture, forestry and horticulture. According to the technical scheme, the preparation method is technically characterized by comprising the following steps: taking sawdust, coco peat, reed residue, bagasse, corn cob grains, rice hull, peanut shell, traditional Chinese medicine residue, perlite and fly ash, proportioning, performing ultraviolet disinfection, and mixing in a material mixing machine; completely dissolving potassium dihydrogen phosphate and urea in wate, then mixing with base material; covering the mixed base material with a film in a fermentation tank; after covering with the film, adding the base material into the material mixing machine, adding fermenting bacteria and mixing; then placing the base material into the fermentation tank again, stacking and covering with the film for biological fermentation, wherein the base material obtained after the fermentation is completed is the nutrition matrix; and finally drying by a dryer. The raw materials used in the nutrition matrix disclosed by the invention are basically agricultural or industrial wastes, low in cost and easily available and can be really turned into treasure; furthermore, the nutrition matrix has the advantages of long fertilizer effect, sufficient nutrients, good moisture retention, good air permeability and short production period and is suitable for large-area popularization and utilization in production.

Description

technical field [0001] The invention relates to the field of agriculture, forestry and horticultural planting, in particular to an environment-friendly light nutrition substrate for soilless cultivation and a preparation method thereof. Background technique [0002] At present, more than 100 countries have begun to use soilless cultivation technology in agricultural production. There are various forms of soilless cultivation techniques, including: hydroponics, aeroponics, matrix cultivation and so on. Soilless cultivation can effectively solve the problems in traditional soil cultivation such as secondary salinization of soil, difficult to control nutrition, and heavy production work, and can effectively provide nutrients needed for plant growth, saving land, water, fertilizer, pesticides, etc. resources, greatly improving the yield and quality of plants. Therefore, soilless cultivation technology has great advantages and has gradually become an important form of large-sca...
