Fabrication method of soilless culture matrix for vegetables

Abstract

The invention discloses a fabrication method of a soilless culture matrix for vegetables. According to the method, a high-temperature super promoter containing beneficial microorganisms is adopted to carry out fermentation rotten treatment on alcohol renewal and straw powder; raw and auxiliary materials, such as coconut shell powder, carbonised rice husk or plant ash, frozen earth or cripple, perlite and vermiculite, are added for preparing. The method comprises concrete operations: collecting and processing the raw and auxiliary materials; composting and fermenting the materials and organic materials according to a formula; and adding coconut shell powder and other auxiliary materials. In the finished soilless culture matrix for the vegetables, the content of moisture is smaller than or equal to 45%; the content of a dry-base organic matter is greater than or equal to 40%; the total nutrient content of dry N, P2O5 and K2O is 2.5-3%; the pH is 5.5-7; the EC is smaller than or equal to 2.5; the particle size is smaller than or equal to 5mm; the material of which the particle size is 2-4mm accounts for 55-60%. By adopting the fabrication method, organic wastes such as the coconut shell powder, the alcohol renewal, and the straw powder are mainly utilized as the raw materials; the culture matrix for the vegetables is produced by adopting high-temperature fermentation; the waste is changed into treasures; harm matters are turned into good matters. The soilless culture matrix is low in cost, light in texture, full in nutrient, and applicable to growth and development of the vegetables, and is a good matrix for the soilless culture of the vegetables.

Description

technical field [0001] The invention relates to a method for manufacturing an agricultural substrate, in particular to a method for manufacturing a vegetable soilless cultivation substrate, and belongs to the technical field of vegetable soilless cultivation. Background technique [0002] Soilless cultivation refers to the method of cultivating with substrate instead of natural soil. It is mainly used in vegetables or flowers. It is a high-yield and high-quality advanced technology that saves water, fertilizer and labor. [0003] Substrate cultivation is a method with the largest promotion area in soilless cultivation. It fixes the roots of crops in organic or inorganic substrates, and supplies the nutrients or water needed by crops through drip irrigation or trickle irrigation. At present, most countries in the world use gravel, sand, mud (grass) charcoal, vermiculite, perlite, rock wool, sawdust, etc. as fixed substrates. With the promotion and application of soilless cu...

Problems solved by technology

However, peat is produced in the Northeast, resources are scarce, and it cannot be regenerated. Enterprises in Jiangsu use peat at high cost; reed powder, traditional Chinese medicine residue, mushroom residue, etc. are large in size and need to be crushed; Difficulties and other shortcomings, it is difficult to meet the needs of vegetable substrate cultivation; Lycium barbarum branches are strong regional, and the application is limited
