Embodiment 1

[0024] 1. Weigh each raw material according to the weight portion for later use: 40kg of potato dregs, 30kg of flax straw, 10kg of gravel, 10kg of perlite, and 10kg of peat.

[0025] 2. Crush the potato dregs, flax stalks and gravels to 60 mesh respectively, mix them evenly, pour water thoroughly to make the water content of the matrix reach 60%, cover tightly with plastic film, and expose to the sun for 90 days to ferment;

[0026] 3. Mix the raw materials processed in step 2 with perlite and peat evenly, cook and sterilize for later use;

[0027] 4. Watering, so that the water content of the material obtained in step 3 is 40%, the adhesive (starch, the heating temperature should be set to 90-150°C, the heating time is 10-15min) and the foaming agent (azobis Potassium amide; the heating temperature should be set at 150-210°C, and the heating time should be 5-10min) and mixed evenly, then added to the material, stirred for 6-10min, and then added with vulcanizing agent (sulfur...

Abstract

The invention discloses a soilless cultivation medium and a preparation method of the soilless cultivation medium, relates to the soilless cultivation medium, and belongs to the technical field of agricultural cultivation. The soilless cultivation medium is characterized by comprising, by weight, 20-40% of potato residues, 20-30% of benne straw, 10-30% of gravel, 10-15% of perlite and 5-15% of peat. The soilless cultivation medium and the preparation method of the soilless cultivation medium have the advantages that recycling of waste such as the potato residues and the benne straw is achieved, the soilless cultivation medium has the good chemical inhibition function and the good biological protection function after being processed through fermentation and disinfection, the number of diseases, insect pests and weeds can be reduced, storage and transport are convenient, when transplanting is carried out, roots cannot be damaged, seedlings cannot be broken, and the survival rate of transplanting is ensured; microcellular foaming is carried out by using adhesives, foaming agents and vulcanizing agents, a specific hole-connected elastomer is formed, root systems can be protected in the process of transport and transplanting, and the survival rate is increased.

Description

technical field [0001] The invention relates to a soilless cultivation substrate, which belongs to the technical field of agricultural cultivation, in particular to a soilless cultivation substrate and a preparation method thereof. Background technique [0002] Historically, the symbol of agricultural civilization is the degree of human intervention and control over crop growth and development. Soil cultivation uses peat or forest humus, vermiculite and other light materials as the seedling substrate to fix the plants, allowing the plant roots to directly contact the nutrient solution, and adopts the modern seedling raising technology of mechanized precision seeding for one-time seedling formation; the culture solution used can be Recycling, the prepared culture solution undergoes selective absorption of ions by plants, the concentration of some ions decreases faster than others, the ratio and pH value of each element change, and it gradually becomes unsuitable for plants. ...
