Problems solved by technology

As mentioned above, in the context of fertilization with extensive use of macronutrient fertilizers, it is obvious that the uptake of micronutrients such as magnesium by plants is affected
However, under the current fertilization habits of excessive fertilization, there is still a lack of systematic research on how to ensure the effective absorption of magnesium by plants

Embodiment 1

[0040]20 kg of magnesium sulfate was weighed to prepare granules with an average diameter of 2.5 mm. Then, weigh 15kg of organic matter (seaweed residue: furfural residue: humic acid = 4:2:1), pulverize it into fine powder, add an appropriate amount of 5% sodium alginate aqueous solution, and uniformly coat the surface of the magnesium sulfate particles by a coating machine Afterwards, take by weighing microbial bacteria powder (Bribacillus lateralis bacteria powder) 3kg, zeolite powder 2kg, add an appropriate amount of 5% sodium alginate aqueous solution after mixing, evenly coat and prepare the particle surface by coating machine, dry That's it.

Embodiment 2

[0042] 25 kg of magnesium sulfate was weighed to prepare granules with an average diameter of 2.5 mm. Then, weigh 18 kg of organic matter (seaweed residue: furfural residue: humic acid = 3:3:1), pulverize it into fine powder, add an appropriate amount of 5% sodium alginate aqueous solution, and uniformly coat the surface of the magnesium sulfate particles by a coating machine Afterwards, take by weighing microbial bacterium powder (Bribacillus lateralis sporogenes bacterium powder: Lactobacillus plantarum bacterium powder=1:2) 4.5kg, bentonite 2.5kg, add an appropriate amount of 5% sodium alginate aqueous solution after mixing, pass the coating machine The surface of the prepared particles is uniformly coated and dried.

Embodiment 3

[0044] 28 kg of magnesium sulfate was weighed to prepare granules with an average diameter of 2.5 mm. Then, weigh 20kg of organic matter (seaweed residue: furfural residue: humic acid = 4:2:1), pulverize it into fine powder, add an appropriate amount of 5% sodium alginate aqueous solution, and uniformly coat the surface of the magnesium sulfate particles by a coating machine Afterwards, take by weighing microbial bacteria powder (Bribacillus lateralis bacteria powder: Lactobacillus plantarum bacteria powder=2:1) ​​6kg, zeolite powder 2kg, add an appropriate amount of 5% sodium alginate aqueous solution after mixing, uniformly by coating machine The surface of the particles obtained by coating and preparation is obtained by drying.

Abstract

The present invention relates to an encapsulated microbial inoculum, comprising 20-40 parts by weight of a fertilizer core, 5-25 parts by weight of an organic intermediate layer and 5-15 parts by weight of a surface layer of the microbial inoculum. Wherein, the fertilizer core includes magnesium fertilizer; the surface layer of the microbial inoculum includes a microbial inoculum and a mineral carrier, and the weight ratio of the two is 1:1 to 4:1; the microbial inoculum includes Brachyspore One or both of Lactobacillus and Lactobacillus plantarum. The coated microbial inoculum can promote the absorption of magnesium by plants, even under the stress of high-concentration N / P / K fertilizers, especially high-concentration K fertilizers, thereby increasing the chlorophyll content in plants. The present invention also relates to the preparation method and use of the coated microbial inoculum.

Description

technical field [0001] The invention belongs to the field of agricultural special functional fertilizers, and particularly relates to a coated microbial inoculum and a preparation method and application thereof. Background technique [0002] my country is a big country in fertilizer production as well as a big country in fertilizer application. Long-term application of large amounts of fertilizers, especially N, P, K and other fertilizers with large amounts of elements, not only aggravates soil compaction, but also deteriorates the soil environment. Excessive accumulation of other macroelements will also lead to changes in the ion concentration of the external environment where plants live, breaking the balance between ions, and then affecting the normal physiological metabolism of plants. antagonism, hindering the absorption of trace elements by plants. [0003] Wang Wenming et al (Atmospheric CO 2 The effect of concentration and nitrogen supply level on the absorption and ...
