Problems solved by technology

At present, 100-200 billion tons of straw are produced in the world's annual agricultural production. China has nearly 600 million tons of straw each year, but less than 20 million tons are used. About 97% of the straw is burned, piled up and abandoned. waste and pollute the environment
[0004] (2) The market prospect of mycorrhizal fungal fertilizer is broad, but the application technology of mycorrhizal fungal fertilizer still needs to be improved
Previous studies have shown that organic materials such as mushroom residues, straw, peat, and compost can effectively increase the infection rate of AMF, but the effects of different organic materials and their treatment methods on AMF application are quite different.

Embodiment 1

[0025] Step 1: Wash the wheat straw, dry it, cut it into 1-2cm length, put it into a mesh bag with a mesh diameter of 0.15mm;

[0026] Step 2: Add water to the container, place the vent tube at the bottom of the container, 1m 3 The aeration rate of water is 0.2L / h, aerate for 30min, remove chlorine gas, then put the mesh bag filled with wheat straw in step 1 into the water, the mass ratio of crop straw to water is 1:1;

[0027] Step 3: Avoid strong direct sunlight during the extraction and fermentation process, keep ventilation, control the outside temperature at 25-30° C., and after 7 days, obtain a wheat straw extract that improves the fertilizer efficiency of mycorrhizal fungi.

[0028] The wheat straw selection meets the following indicators: cellulose ≤ 2.0%, hemicellulose ≥ 2.2%, lignin ≥ 1.0% and C / N between 20-50.

[0029] The above-mentioned wheat straw extraction solution for improving the fertilizer efficiency of mycorrhizal fungi complies with the "Farmland Irriga...

Embodiment 2

[0032] Step 1: Wash the corn stalks, dry them, cut them into 2-4cm lengths, and put them into a mesh bag with a mesh diameter of 0.20mm;

[0033] Step 2: Add water to the container, place the vent tube at the bottom of the container, 1m 3The aeration rate of the water is 0.3L / h, aerate for 30min to remove chlorine gas, then put the mesh bag filled with corn stalks in step 1 into the water, the mass ratio of corn stalks to water is 1:4;

[0034] Step 3: During the extraction and fermentation process, avoid strong direct light, keep ventilation, and control the outside temperature at 25-30° C. After 7 days, obtain a corn straw extract that improves the fertilizer efficiency of mycorrhizal fungi.

[0035] The corn stalk selection meets the following indicators: cellulose≤2.0%, hemicellulose≥2.2%, lignin≥1.0% and C / N between 20-50.

[0036] The corn stalk extract solution prepared above to improve the fertilizer efficiency of mycorrhizal fungi complies with the "Farmland Irrigati...

Abstract

The invention discloses crop straw leach liquor for improving fertilizer efficiency of mycorrhizal fungi fertilizer and a preparation method of the crop straw leach liquor, belonging to the field of fertilization of biofertilizer. The preparation method disclosed by the invention comprises three parts, namely material selection, preparation process selection and quality index selection; the method for fertilizing the crop straw leach liquor comprises parameter selection of fertilizing condition, fertilizing time and fertilizing amount. The material selected by the method is easy to obtain, low in cost, simple in preparation process and simple and fast in fertilizing method, and the prepared crop straw leach liquor is high in efficiency of promoting crop seedling to grow, and short in time. The biomass liveweight of the crop seeding is improved by over 30% after the crop straw leach liquor is watered about 40 days. The material adopted by the method is not added chemically synthesized substance, and the prepared crop straw leach liquor has no pollution on the environment and accords with the requirements of sustainable development of agriculture.

Description

technical field [0001] The invention belongs to the technical field of biological fertilizer application, and in particular relates to a crop straw extraction solution for improving the fertilizer efficiency of mycorrhizal fungi and a preparation method thereof. Background technique [0002] (1) The utilization of crop straw resources has attracted much attention [0003] Crop straw is one of the main wastes in agricultural production. It is rich in nitrogen, phosphorus, potassium and trace elements. It is an important renewable resource and has great comprehensive utilization value. At present, 100-200 billion tons of straw are produced in the world's annual agricultural production. China has nearly 600 million tons of straw each year, but less than 20 million tons are used. About 97% of the straw is burned, piled up and abandoned. waste, and cause environmental pollution. Burning straw will also cause evaporation of soil moisture and damage to soil structure, resulting i...
