Embodiment Construction

[0018] Below in conjunction with 6 examples the present invention is described in detail, but the present invention is not limited to the given embodiment.

[0019]

[0020] In the example, the EM stock solution, honey and water were mixed first, and then 10% calcium sulfate suspension was added to the mixed solution, and placed in a rotary shaker with a speed of 120r / min to 180r / min under airtight conditions. Anaerobic fermentation for 3-5 days, standing and filtering, and concentrating the filtrate. According to the method provided by NY / T789-2004 (compound microbial fertilizer) standard, the pH of the concentrated solution of the compound microbial calcium preparation prepared in each example is 6.0-7.5, and the effective number of viable bacteria (CFU) is greater than 100 million / ml. Calcium content 0.5%-1.0%.

[0021] In the complex microbial fermentation process, the role of honey is to provide C source and energy for microbial rejuvenation and metabolism. After the ...

Abstract

The invention belongs to the technical field of multifunctional biological preparations, and provides a method for preparing a compound microbial calcium agent. The method comprises the following preparation step of: adding a 10 percent calcium sulfate suspension in a process for preparing an active liquid of compound microorganisms, and comprises the following specific steps of: compounding 3-5 percent of an EM stock solution, 2-5 percent of honey, 5-10 percent of a calcium sulfate suspension and 80-92 percent of deionized water according to volume proportions, and mixing uniformly; putting into a rotary shaking table of which the speed is 120-180 revolutions per minute under a room temperature enclosed condition for performing anaerobic fermentation for 3-5 days; and standing and filtering for separating solid from liquid to obtain a liquid preparation of compound microbial calcium. The method has the advantages that: the fermented calcium is in a chelated (complexed) state or a cation-anion balance state, is dissolved into water, and is easy to be absorbed by plants through foliar application, and physiological disorder (such as tomato fruit blossom-end rot caused by the lack of calcium) caused by the lack of calcium in plants can be eliminated effectively.

Description

technical field [0001] The invention belongs to the technical field of multifunctional biological preparations, and converts insoluble calcium sulfate into water-soluble active calcium by using compound microorganism fermentation technology. The prepared compound microbial calcium agent can be used for foliar spraying to effectively solve the physiological obstacles caused by calcium deficiency in plants (such as tomato fruit navel rot caused by calcium deficiency). The microbial preparation has simple and convenient culture and preparation process, low invention cost, simple use method and broad application prospect. Background technique [0002] Calcium is an essential nutrient element for plants. There are many physiological diseases of plants caused by calcium deficiency. The most common one is tomato fruit navel rot caused by calcium deficiency, which has a great impact on yield and quality. At the same time, due to the high multiple cropping index and large-scale appl...
