Soilless culture substrate and preparation method thereof

Abstract

The invention discloses a soilless culture substrate. The soilless culture substrate comprises the following raw materials in parts by weight: 20-40 parts of animal waste, 10-20 parts of perlite, 5-10 parts of vermiculite, 8-13 parts of soy sauce residues, 6-12 parts of peat, 15-25 parts of modified attapulgite, 6-13 parts of bean cakes, 5-10 parts of banana peels, 3-7 parts of lignin, 2-4 parts of a trichoderma anti-mildew agent, 3-6 parts of activated carbon, 5-9 parts of cereal chaff, 2-3 parts of sugar cane molasses, 2-4 parts of light calcium carbonate, 3-8 parts of water hyacinth residues, 7-14 parts of inorganic fertilizers and 2-5 parts of a slow release fertilizer water-retaining agent. The soilless culture substrate is stable in chemical property, moderate in pH value and good in permeability; the physical and chemical performance indexes meet requirements of the soilless culture substrate; and the soilless culture substrate is abundant in nutrition, can meet requirements of nutrition in a growing period of plants, provides a good and stable substrate environment for the plants, and is suitable for culturing the plants.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a soilless cultivation substrate and a preparation method thereof. Background technique [0002] Organic substrate soilless cultivation technology is a kind of high-efficiency and low-cost soilless cultivation technology created by our country. This technology does not use nutrient solution prepared by chemical fertilizers, but uses harmless treated agricultural waste (straw, poultry manure, fungus chaff, etc.) crop. In the process of crop growth, watering is the main method. The technical operation is simple, practical and efficient, which greatly reduces the use of chemical fertilizers, and the products produced are green and pollution-free. It not only has the advantages of soilless cultivation, but also overcomes the defects that the nutrient solution soilless cultivation technology is difficult, high cost, difficult to popularize and popularize, and cannot ...

AI Technical Summary

Problems solved by technology

[0003] At present, the fertilizers in the existing cultivation substrates on the market cannot meet the needs of the entire growth period of the crops. Therefore, it is necessary to continuously topdress the fertilizer during the cultivation process, or use a more expensive nutrient solution cultivation system to irrigate the vegetable-specific nutrient solution, which costs a lot of money. laborious

The growth process of vegetable crops requires a lot of fertilizers, but if the N fertilizer required by the crops is added to the substrate, it will cause the phenomenon of plant burning
