Layered cultivation substrate for mushroom residue organic fertilizer

Abstract

The present invention relates to a layered cultivation substrate for a mushroom residue organic fertilizer. The layered cultivation substrate for the mushroom residue organic fertilizer is composed ofa peat composite substrate layer, a first mushroom residue composite substrate layer and a second mushroom residue composite substrate layer from top to bottom. The peat composite substrate layer isprepared by mixing 8-10 parts of peat, 2-4 parts of vermiculite and 2-4 parts of perlite and has a thickness of 4-6 cm; the first mushroom residue composite substrate layer is prepared by mixing 20-40parts of a dopant and 60-80 parts of mushroom residue organic fertilizers and has a thickness is 4-6 cm; the second mushroom residue composite substrate layer is prepared by mixing 10-20 parts of a dopant and 80-90 parts of mushroom residue organic fertilizers and has a thickness of 8-12 cm, and the above parts are all by volume. The layered cultivation substrate for the mushroom residue organicfertilizer is divided into three layers, EC values gradually increase from top to bottom, the layered cultivation substrate for the mushroom residue organic fertilizer is very suitable for growth characteristics of cherry tomatoes and other crops, and chemical fertilizers are greatly reduced or even not used. The technology has far-reaching significance in saving resources, improving the environment, using waste, reducing cost of soilless cultivation of crops, increasing income of edible fungi and vegetable growers, and shortening growth cycles of the crops.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation substrates, and in particular relates to a vegetable cultivation substrate made of mushroom dregs organic fertilizer. Background technique [0002] As the edible fungus industry continues to expand and its scale continues to increase, more and more mushroom residues are produced after the cultivation of edible fungi. Usually, every kilogram of edible fungi produced will produce 5 kg of waste mushroom residue. If these waste mushroom residues are not handled properly, it will not only waste resources, but also breed diseases and pests and damage the environment. [0003] Peat and coconut peat are the most used substrates in vegetable soilless cultivation, but both peat and coconut peat have limitations. Both of them have relatively low nutrient content, are relatively dependent on chemical fertilizers, and peat reserves are limited, so it is impossible recycled resources. [0004] Existi...

AI Technical Summary

Problems solved by technology

[0005] Traditional substrate cultivation requires multiple fertilization at different growth stages, especially the cultivation of peat and coconut peat, which is inseparable from the continuous drip irrigation of nutrient solution

Moreover, if the substrate fertility is too thick or the substrate fertility is too thin, it will have adverse effects on the growth, flowering period and even yield of the crops. During the entire growth cycle, it is necessary to fertilize multiple times and constantly adjust the amount of fertilizer, which greatly increases the amount of labor and increases the cost. How to get a Cultivation substrate, which can make crops only need to be irrigated with water during the whole growth cycle without fertilization, can greatly save labor and cultivation costs, and is an urgent problem to be solved by those skilled in the art
