Method for preparing vegetable cultivation medium by virtue of earthworm hydrolysate

Abstract

The invention relates to a method for preparing a vegetable cultivation medium by virtue of earthworm hydrolysate, and belongs to the field of nutrition media for plants and making methods for the nutrition media. The vegetable cultivation medium is prepared by breeding earthworms with stacked poultry and livestock manure to convert the manure for feeding the earthworms into earthworm cast, mixing the bred earthworms and subtilisin to automatically hydrolyze the earthworms to obtain the earthworm hydrolysate and adding a proper amount of peat into a mixture of the earthworm cast and the earthworm hydrolysate. Examples show that the method is unique and novel; the prepared cultivation medium is high in water and fertilizer retention, and plant roots can be easily fixed; moreover, the cultivation medium contains large amounts of amino acids and proteins, so that survival rates of cultivated vegetables are remarkably increased by over 88 percent.

Description

technical field [0001] The invention relates to a method for preparing a vegetable cultivation substrate by using an earthworm body hydrolyzate, and belongs to the field of plant nutrition substrates and preparation methods thereof. Background technique [0002] Substrate cultivation is a method with the largest promotion area in soilless cultivation. It is a cultivation method that uses a solid substrate to fix the plant root system and absorb nutrient solution and oxygen through the substrate. 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 cultivation technology, the demand for substrates is increasing, and enterprises specializing in the production of substrates have emerged as the times require, and the types of substrates are becoming more and more abundant, gradually showing a trend of subdivision and specialization. . ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem mainly solved by the present invention: the production cost of the currently commonly used vegetable cultivation substrate is very high, and the particles need to be pulverized during the production process, which increases the workload and the nutrient components of the cultivation substrate mixed to form the cultivation substrate often cannot meet the needs of vegetable growth. The yield is relatively low. If chemical fertilizers are used in conjunction with the use, the vegetables will not be fresh enough and do not meet the requirements of organic food production. A method for preparing vegetable cultivation substrates using earthworm body hydrolyzate is provided. Manure farming earthworms, using earthworms to feed on feces and transforming them into vermicompost, then mixing the cultured earthworms with subtilisin to make them self-hydrolyzed to obtain earthworm body hydrolyzate, and finally mixing and preparing earthworm body hydrolyzate and earthworm body hydrolyzate to add appropriate amount of peat. A kind of vegetable cultivation substrate
