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 deficiencies, it is difficult to meet the needs of industrial seedlings
Li Pingping of Jiangsu University and others used vinegar grains to produce plant seedlings and cultivation substrates. Because it was proposed earlier, some production processes are not too mature, and it is mainly used for cultivation, not strictly a special seedling substrate.

Embodiment 1

[0025] A vegetable seedling raising substrate, the raw materials are organic wastes such as vermiculite, perlite, biogas mud, carbonized rice husk, fermented alcohol biogas residue and coconut shell powder base material; the coconut shell powder base material is domestic coconut brick plus water The material formed after the expansion treatment has an expansion coefficient of 4, a water content of 40%, and a particle size of 1-6mm; biogas sludge is the material obtained by drying and crushing the bottom sediment of the biogas tank, and the particle size is 1-3mm; carbonized rice husk is The ashes left after the rice husk is burned and carbonized; the alcohol biogas residue is the leftovers after extracting alcohol from cassava raw materials, and then the residue formed after anaerobic fermentation to generate biogas.

[0026] The matrix formula components are as follows by volume ratio: 30 parts of coconut shell powder base material, 15 parts of alcohol biogas residue, 25 parts...

Embodiment 2

[0029] A vegetable seedling raising substrate, the raw materials are organic wastes such as vermiculite, perlite, biogas mud, carbonized rice husk, fermented alcohol biogas residue and coconut shell powder base material; the coconut shell powder base material is domestic coconut brick plus water The material formed after the expansion treatment has an expansion coefficient of 6, a water content of 50%, and a particle size of 1-6mm; biogas sludge is the dried and pulverized material at the bottom of the biogas tank, with a particle size of 1-3mm; carbonized rice husk is The ashes left after the rice husk is burned and carbonized; the alcohol biogas residue is the leftovers after extracting alcohol from cassava raw materials, and then the residue formed after anaerobic fermentation to generate biogas.

Abstract

The invention discloses a vegetable seedling growing substrate, and belongs to the technical field of soilless culture techniques. The substrate comprises the following components: coconut shell base stock, alcohol biogas residue, carbonized rice hull, biogas slurry, perlite and vermiculite at a ratio of (15-30):(15-30):(15-25):(0.5-2):(5-10):(15-25), wherein the water content of the substrate is 35-50%, the total porosity is 65-95%, the organic substance content is greater than or equal to 20%, the total nutrient content is 3-5%, the particle size is 0.1-4.9 mm, the volume-weight is 0.2-0.8 g / cm<3>, the gas water ratio is 1:(2-4), the EC value is less than or equal to 2.5 mS / cm, and the pH value is 5.8-7.5. The vegetable seedling growing substrate mainly adopts organic waste as raw materials which are subjected to high-temperature fermentation treatment, the waste is turned into wealth, and the harm is turned into goodness, and moreover, the substrate is low in cost, light in weight, comprehensive in nutrient, is applicable to growth and development of vegetable seedlings, and is a good substrate for vegetable soilless culture industrial plug seedling.

Description

technical field [0001] The invention relates to a nutrient substrate for soilless cultivation of vegetables, in particular to a substrate for growing vegetable seedlings, and belongs to the technical field of soilless cultivation of vegetables. Background technique [0002] Soilless cultivation refers to the method of irrigating with substrate or nutrient solution without using natural soil. It is mainly used in the cultivation of vegetables and other crops. It is a high-yield and high-quality advanced technology that saves water, fertilizer and labor. In the middle of the 19th century, it began to be used in agricultural production in the 1930s. It was widely used in the Netherlands, Japan, New Zealand, Italy and other countries. At present, soilless cultivation technology has been applied and developed in more than 100 countries around the world. [0003] The research and application of soilless cultivation technology in my country started relatively late, but the relative...
