Embodiment 1

[0046] Embodiment 1, the preparation of pH-sensitive organic fertilizer

[0047] (1) Preparation of organic fertilizer particles coated with dopamine on the surface

[0048]Weigh 1.5g Tris and place it in a beaker, add about 900mL of deionized water, adjust the pH of the Tris-HCl solution to 8-8.5 with 6M HCl; crush the straw, dead leaves, hay, bran, etc. through a 500-mesh sieve , to obtain organic matter powder; get 40g of said organic matter powder and add in the above-mentioned Tris-HCl solution, then add the mixed bacteria powder of Bacillus subtilis, saccharomyces, lactic acid bacteria whose total mass is 10g, and mass ratio is 1:2:2, mix well , and the solution was fixed to 1L; 5g of dopamine hydrochloride was added, stirred at room temperature for more than 12 hours, and suction filtered to obtain organic fertilizer particles coated with dopamine on the surface, and the organic fertilizer particles were composed of the organic powder and the mixed bacteria .

Embodiment 2

[0052] Embodiment 2, the living bacteria release experiment of pH-sensitive organic bacterial fertilizer

[0053] Take 6g of the pH-sensitive organic bacterial fertilizer prepared according to the method described in Example 1, divide it into 3 parts on average, place it in sterile water with a pH value of 5, 7, and 9 for 1 day, and then detect the different pH values. , The live bacterial release of pH-sensitive organic fertilizer.

[0054] Plate detection method to detect the release of viable bacteria detection method:

[0055] 1) Prepare a solution according to the mass volume ratio of the placed sample: sterile water at a ratio of 1:10, and filter the solution through a 3-micron filter membrane to filter out the dopamine attached to the surface of the unreleased live bacteria Organic fertilizer particles and organic bacteria particles coated with polymer molecules;

[0056] 2) Collect the filtrate, add glass beads, let it stand for 20 minutes, and shake it on a rotary s...

Abstract

The invention provides pH sensitive organic bacterial manure. The bacterial manure comprises organic matters, bacteria beneficial to the growth of plants, dopamine or salt thereof, and pH sensitive polymer molecules synthesized from acrylate by adopting graphene oxide as a cross-linking agent. The dopamine is attached to the surface of the organic matter and beneficial bacteria, the surface of thedopamine is coated with the pH sensitive polymer molecules, so that the pH sensitive organic bacterial manure provided in the invention capable of adjusting the release amount of organic bacterial fertilizer wrapped therein can be prepared. By applying the pH sensitive organic bacterial manure provided in the invention in the salinization soil, the organic fertilizer and live bacteria in the organic bacterial manure can be rapidly released, so that the salinization problem of the soil can be rapidly improved; and by applying the pH sensitive organic bacterial manure in the acidified soil, therelease rate of the fertilizer can be effectively retarded, the loss of the fertilizer in the acidic soil can be prevented, and the utilization efficiency of the fertilizer can be improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizer development, and in particular relates to a pH-sensitive organic bacterial fertilizer. Background technique [0002] Generally, the climate varies greatly across my country. With the large-scale development of sustainable modern agriculture, the excessive use of fertilizers and human activities have caused more and more serious problems in terms of soil acidity and alkalinity. The physical and chemical properties of soil have a significant impact on the growth environment of plants and the utilization efficiency of fertilizer itself. Salinized soil is not conducive to the growth of crops, and a large number of hydrogen ions in acidic soil lead to the loss of some fertilizers, which greatly reduces the utilization efficiency of fertilizers. For the solution of above-mentioned problem, also do not have an effective means to propose at present. Contents of the invention [0003] The invention ...
