Embodiment 1

[0035] A special compound microbial fertilizer for tobacco, the formula is as follows: 8% ammonium sulfate, 17% diammonium phosphate, 6% calcium magnesium phosphate, 23% potassium sulfate, 34% peat, and 10% compound microbial liquid. Zinc sulfate 0.5%, ferrous sulfate 0.5%, ammonium molybdate 0.5%, manganese sulfate 0.5%.

[0036] The composite microbial liquid is prepared from Bacillus laterosporus with the preservation number of CGMCC No.5090 and Bacillus subtilis with the preservation number of CGMCC No.5091, respectively, which are respectively prepared by fermentation , And then mixed according to the weight ratio of 1:1.

[0037] The preparation process of Bacillus Laterosporus bacterial solution is as follows:

[0038] Activate the Bacillus Laterosporus strain first, and then rinse the slope with 5ml sterile water to form a bacterial suspension. The bacterial suspension is connected to a 500ml Erlenmeyer flask, which contains 100ml New 1 liquid medium, which is cultured on a ...

Abstract

The invention relates to a special composite microbial fertilizer for tobacco use and its preparation method. The fertilizer comprises a composite microbial solution and an organic-inorganic compound fertilizer that total 100% by weight percent. The composite microbial solution is mixed by a bacterial solution of new bacillus laterosporus and a bacterial solution of bacillus subtilis. The special fertilizer of the invention can provide a solution to the problems of excessive application of chemical fertilizers, poor pertinence, imbalanced nutrition, unstable application effect of existing microbial fertilizers for tobacco, and can achieve obvious increase of production and income after application.

Description

Technical field [0001] The invention relates to a special fertilizer for tobacco and a preparation method thereof, in particular to a special compound microbial fertilizer for tobacco and a preparation method thereof. Background technique [0002] Tobacco is a leaf-use economic crop, which has the characteristics of preferring potassium and phosphorus but less nitrogen fertilizer. At present, a large number of inorganic chemical fertilizers are used in production, resulting in deterioration of the physical and chemical properties of tobacco-growing soil, soil compaction, poor air permeability, and reduced water and fertility retention. In addition, excessive application of chemical fertilizers can also cause serious environmental impacts. When excessive chemical fertilizers are applied, the nutrients that are not absorbed by the soil will be lost with the water, causing excess nutrients in nearby water sources, accelerating the growth of algae and affecting the entire ecosystem. ...
