Embodiment 1

[0038] This embodiment provides a soybean nutrient solution, wherein the soybean nutrient solution is prepared by the following method, specifically including the following steps:

[0039] (1) Take crushed corn stalks with a particle size of ≤ 2cm, pig manure with a particle size of ≤ 1cm after crushing, and mushroom slag with a particle size of ≤ 1cm after crushing, mix and stir evenly in a mass ratio of 6:2:2 to obtain a mixed material ;

[0040](2) Add a functional bacterial agent equivalent to 15% of the mass of the mixed material to the mixed material, then add water until the water content of the mixed material is 60%, and control the temperature to not exceed 50°C for fermentation and cultivation for 6 days;

[0041] Wherein, the functional bacterial agent is prepared by the following method: in parts by weight, take 100 parts of solid medium (bran: bran: rice husk: 6:3:1), add 100 parts of water, and then add 1 part of sulfuric acid After the ammonium is sterilized, a...

Embodiment 2

[0045] This embodiment provides a soybean nutrient solution, wherein the soybean nutrient solution is prepared by the following method, specifically including the following steps:

[0046] (1) Take corn stalks with a particle size of ≤5 cm after crushing, pig manure with a particle size of ≤2 cm after crushing, and mushroom dregs with a particle size of ≤2 cm after crushing, mix and stir evenly at a mass ratio of 4:3:3 to obtain a mixed material;

[0047] (2) Add a functional bacterial agent equivalent to 15% of the mass of the mixed material to the mixed material, then add water until the moisture content of the mixed material is 65%, and ferment and cultivate for 5 days at a temperature not higher than 50°C;

[0048] Wherein, the functional bacterial agent is prepared by the following method: in parts by weight, take 100 parts of solid medium (bran: bran: rice husk: 6:3:1), add 100 parts of water, and then add 2 parts of sulfuric acid After the ammonium is sterilized, add 10...

Embodiment 3

[0052] This embodiment provides a soybean nutrient solution, wherein the soybean nutrient solution is prepared by the following method, specifically including the following steps:

[0053] (1) Take corn stalks with a particle size of ≤4cm after crushing, pig manure with a particle size of ≤1cm after crushing, and mushroom slag with a particle size of ≤1cm after crushing, mix and stir evenly at a mass ratio of 5:2.5:2.5 to obtain a mixed material ;

[0054] (2) Add a functional bacterial agent equivalent to 15% of the mass of the mixed material to the mixed material, then add water until the moisture content of the mixed material is 50%, and ferment for 4 days at a temperature not higher than 50°C;

[0055] Wherein, the functional bacterial agent is prepared by the following method: in parts by weight, take 100 parts of solid medium (bran: bran: rice husk: 6:3:1), add 100 parts of water, and then add 1 part of sulfuric acid After the ammonium is sterilized, add 10 parts of the...

Abstract

The invention discloses a soybean nutrient solution as well as preparation and using methods of the soybean nutrient solution. The preparation method of the soybean nutrient solution comprises the following steps: (1) respectively weighing 40-60 parts by weight of smashed crop straws, 20-30 parts by weight of poultry excrements and 20-30 parts by weight of mushroom residues, mixing and uniformly stirring to obtain a mixed material; (2) adding a functional fungicide into the mixed material, then, adding water until the mixed material contains 50-65% of water, and fermenting for 3-7 days under the condition of controlling the temperature at lower than or equal to 50 DEG C, wherein the functional fungicide accounts for 10-20% of the mass of the mixed material; and (3) spraying water into the fermented mixed material according to the ratio of 5-25L / kg, collecting leachate and filtering to obtain the soybean nutrient solution. The raw materials of the soybean nutrient solution disclosed by the invention are extracted from agricultural wastes, so that the soybean nutrient solution is low in cost and preparation expense, convenient to operate, capable of effectively promoting the growth of soybeans and improving the diseases resistance.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a soybean nutrient solution and a preparation method and application method thereof. Background technique [0002] Crop straw contains a certain amount of carbon, nitrogen, phosphorus, potassium, calcium, silicon and other elements, and is also rich in organic substances such as cellulose, hemicellulose, lignin and protein. Straw contains a large amount of nutrients that can be used by animals and plants. The carbon content in straw is about 40-60%, and the nitrogen content is about 0.6-1.1%. It is a renewable biological resource with comprehensive utilization value. Among them, corn stalks are an important remaining biomass resource in my country's agricultural production, with an annual output of about 210 million tons and a growing trend. With the development of agricultural production, the transformation of farmers' lifestyles, and the process of urbanization, the surp...
