Composite microbial organic bacterial fertilizer capable of improving salt resistance of seedlings and preparation method of composite microbial organic bacterial fertilizer

Abstract

The invention discloses composite microbial organic bacterial fertilizer capable of improving salt resistance of seedlings. The composite microbial organic bacterial fertilizer is prepared from the following raw materials in parts by weight: 10 to 19 parts of potatoes, 1 to 4 parts of brown sugar, 16 to 24 parts of chaetomium globosum fermented liquid, 1 to 4 parts of disodium hydrogen phosphate, 1 to 4 parts of calcium chloride, an appropriate amount of 0.1 mol / L sodium chloride solution, an appropriate amount of 0.2 mol / L acetate solution, 23 to 31 parts of chitosan, 2 to 6 parts of glutaraldehyde, 12 to 19 parts of wheat bran, 12 to 18 parts of furfural residue, 6 to 11 parts of ammonium sulfate, 7 to 13 parts of potassium sulfate, 16 to 23 parts of manure and an appropriate amount of deionized water. According to the composite microbial organic bacterial fertilizer, the chaetomium globosum is cultured in a fermenting manner, then the chitosan is used for wrapping the chaetomium globosum fungicide to enable the chaetomium globosum fungicide to be slowly released, by virtue of microbial secondary fermentation treatment, the demand of crops on various nutrients can be satisfied, the growth of the chaetomium globosum strain can be satisfied and promoted, the soil to which the fertilizer is applied can continuously accumulate the nutrients and improve the insecticide and anti-disease capacity, and the salt resistance of the crop seedlings can be obviously improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a compound microbial organic fertilizer capable of improving the salt tolerance of seedlings and a preparation method thereof. Background technique [0002] The unreasonable use of chemical fertilizers for a long time has brought about problems such as soil compaction, salinization, fertility decline, ecological damage, and decline in the quality of agricultural and sideline products, and has been highly valued by relevant state departments and agricultural science and technology circles. Our country has been seeking to overcome the disadvantages of soil compaction, salinization, soil fertility decline and agricultural production cost increase caused by extensive use of chemical fertilizers. [0003] Microbial fertilizer is a kind of product that obtains a specific fertilizer effect through the action of microbial life activities, making it a kind of ...
