Embodiment Construction

[0017] Below in conjunction with 6 examples the present invention is described in detail, but the present invention is not limited to the given embodiment.

[0018]

[0019] In the embodiment, the EM stock solution, honey and water are mixed according to the above volume ratio, and then 20% magnesium carbonate suspension is added to the mixed solution, and the speed is 120r / min~180r / min under airtight conditions. Fermented in a rotary shaker at room temperature for 6-7 days. As measured by standard methods, the pH of the chelated magnesium preparations prepared in each example is 6.5-7.5, the effective viable count (CFU) is greater than 100 million / ml, and the content of active magnesium is 5%-6%.

[0020] In the complex microbial fermentation process, the role of honey is to provide C source and energy for microbial rejuvenation and metabolism. After the microorganism obtains C source and energy, it changes from a dormant state to an active state. The complex microbial liq...

Abstract

The invention belongs to the technical field of multifunctional foliage fertilizer and provides a method for preparing chelating magnesium. The preparation steps are as follows: preparing 20% of magnesium carbonate suspension first by volume percent, and adding the 20% of magnesium carbonate suspension during the preparation process of compound microbial activated solution; and the specific method comprises the steps of combining the following materials by volume ratio: 3 % to 5% of EM stock solution, 2% to 5% of honey, 25% to 30% of the magnesium carbonate suspension and 60% to 70% of deionized water, blending the mixture uniformly, and putting the mixture in a rotary shaking table with the speed of 120 r / min to 180 r / min and fermenting for 6 to 7 days under ambient temperature. Therefore, chelating magnesium can be obtained. The method has the advantages that the magnesium fermented with compound microbe is in a chelating (complexation) state or an anion cation balance state, is easily insoluble in water, and is easy to be absorbed by plants; and when the chelating magnesium is applied on leaves, the chlorophyl content of vegetables can be improved, and the problem of physiological barrier of plants caused by lack of magnesium can be solved effectively.

Description

[0001] technical field [0002] The invention belongs to the technical field of multifunctional foliar fertilizers, and uses a compound microbial fermentation technology to convert insoluble magnesium carbonate into water-soluble active chelated magnesium. The prepared chelated magnesium agent is used for foliar spraying, which can effectively solve the physiological obstacles caused by plant magnesium deficiency (such as abnormal color and growth deformity of green peppers caused by magnesium deficiency). The preparation has the advantages of simple cultivation process, low application cost and simple use method. It has a wide range of applications and has broad application prospects. Background technique [0003] Magnesium is an essential nutrient element for plants and plays an important role in chlorophyll synthesis and photosynthesis. There are many physiological disorders caused by magnesium deficiency in plants. The most common ones are abnormal color and abnormal g...
