Problems solved by technology

For example, rock wool cultivation needs to add nutrient solution, and materials such as perlite and vermiculite have small bulk density, which brings a lot of inconvenience to seedling cultivation, and because the fertilizers in these substrates themselves cannot provide various nutrients needed for seedling growth and development. Substances, whether taken alone or in combination, require additional nutritional supplementation
This will cause many environmental problems, and also greatly increase the difficulty and cost of seedling cultivation

Abstract

The invention discloses a soilless cultivation medium. The soilless cultivation medium is prepared from, by weight, 10-30 parts of plant straws, 8-15 parts of edible fungus residues, 12-20 parts of fish and shrimp leftovers, 10-30 parts of diatomite, 13-22 parts of slag, 10-20 parts of fish pond silt, 9-18 parts of sepiolite, 11-17 parts of attapulgite, 1-2 parts of a water-retaining agent, 15-25 parts of animal dung and 2-3 parts of a microbial fermenting agent. The soilless cultivation medium has great ventilative and water retention functions and also has the advantage of rich nutrition, plants can acquire more comprehensive nutrients in a growth process, the growth period is shortened, and production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of cultivation technology, and in particular relates to a soilless cultivation substrate and a preparation method thereof. Background technique [0002] Soilless cultivation uses peat or forest leaf 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 technology of mechanized precision seeding for one-time seedling formation. At present, the most commonly used cultivation substrates are mainly inorganic substrates such as vermiculite, perlite and rock wool, and organic substrates such as peat (also known as peat). These substrates can be used alone or mixed in a certain proportion. These substrates are aerated and permeable, providing the benefits of mineral fertilization, water retention and improved physical properties. Although the traditional seedling substrate has many advantag...
