Novel microorganism seedling growing nutrient liquid as well as preparation method and application thereof

Abstract

The invention provides a novel microorganism seedling growing nutrient liquid as well as a preparation method and application thereof. Soil bacillus subtilis is used in the nutrient liquid, and the soil bacillus subtilis is capable of promoting crop growth and has the characteristics of promoting roots, strengthening seedlings, preventing bacteria and preventing diseases. The novel microorganism seedling growing nutrient liquid is prepared by compounding the soil bacillus subtilis, ammonium dihydrogen phosphate, magnesium sulfate heptahydrate, EDTA (Ethylene Diamine Tetraacetic Acid) ferric salt, boric acid, manganese sulfate, zinc sulfate, copper sulfate and ammonium molybdate in a certain ratio, the yield of crops can be effectively increased, the yield of each acre is increased, meanwhile leaves of the crops can be in dark green and are thickened, and the photosynthesis can be enhanced.

Description

Technical field

[0001] The invention belongs to the technical field of microorganisms, and particularly relates to a novel microbial seedling raising nutrient solution and a preparation method and application thereof. Background technique

[0002] With the improvement of people's living standards and the enhancement of environmental protection awareness, in the international or domestic market, the access system for vegetable products is implemented, and the vegetables to enter the market must be pollution-free vegetables. The substrate is an important component of the vegetable factory seedling system. It is not only the place where the seedlings live, but also the medium for the water, nutrients, temperature and other requirements of the seedlings. Like soil, substrate has the basic functions of supporting and nutritious crops, but it is different from soil, and even better than soil in some aspects. Therefore, studying the physical and chemical properties of the substrate is ...

Examples

Embodiment 1

[0032] A new type of microbial seedling nutrient solution, the raw materials include the above-mentioned soil Bacillus subtilis, ammonium dihydrogen phosphate, magnesium sulfate heptahydrate, EDTA iron salt, boric acid, manganese sulfate, zinc sulfate, copper sulfate and ammonium molybdate, 1L soil subtilis spore The concentration of other raw materials in the bacillus liquid:

[0033] Ammonium dihydrogen phosphate 5~15g / L

[0034] Magnesium sulfate heptahydrate 40~60g / L

[0035] EDTA iron salt 2~10g / L

[0036] Boric acid 2~10g / L

[0037] Manganese sulfate 2~10g / L

[0038] Zinc sulfate 0.1~2 g / L

[0039] Copper sulfate 0.1~2 g / L

[0040] Ammonium molybdate 0.05~1 g / L.

[0041] Further, the number of viable bacteria in the soil Bacillus subtilis bacterium liquid is 5.78×10 11 cfu / mL-8.13×10 12 cfu / mL. The Latin name of the soil Bacillus subtilis is Bacillussubtilis B2, the strain has been deposited in the General Microbiology Center of China Microbial Strain Collection Management Comm...

Embodiment 2

[0050] This example is a preferred solution on the basis of Example 1. In 1L of soil Bacillus subtilis, the concentrations of other raw materials are:

[0051] Ammonium dihydrogen phosphate 11.5g / L

[0052] Magnesium sulfate heptahydrate 49.3g / L

[0053] EDTA iron salt 5.6g / L

[0054] Boric acid 5g / L
