Problems solved by technology

However, due to relatively complicated management and unsatisfactory yields, the production benefits have not yet reached the expected level. There are two main problems: First, hydroponic vegetables are grown in nutrient solution, which does not have the same level of soil as in traditional soil cultivation. Buffering, so the control of nutrient solution concentration, the ratio of various nutrients, pH and temperature needs to be more stringent
[0005]1. Hydroponic cucumbers grow rapidly, the plants are prone to premature aging (flower topping), and the yield is low. Due to the rapid expansion of cucumber fruits, the quality declines
[0006]2. The root system of hydroponic cucumber grows in the nutrient solution, and the utilization rate of nutrient elements in the nutrient solution is low. If root disease occurs in the planting system, it will quickly Large-scale spread, great harm to cucumber production
Therefore, it is necessary to disinfect the production water, seedling substrate, nutrient solution and facilities and equipment in time, which is labor-intensive and time-consuming.
[0007]3. The root system of cucumber has autotoxicity, and the self-toxic substance secreted by the root system accumulates continuously in the culture solution, which affects the growth of cucumber in the later stage. It is necessary to replace the culture solution regularly, and waste Liquid treatment not only increases the cost but also pollutes the environment

Embodiment 1

[0039] The hydroponic cucumber nutrient solution additive of the present application is a kind of compound microbial bacterial liquid, provided by the microbial fertilizer research group of Gansu Agricultural University College of Grasslands, the compound microbial bacterial liquid is composed of nitrogen-fixing bacteria (autogenous nitrogen-fixing bacteria), phosphorus-dissolving bacteria; secreting plant Composition of four active microorganisms: hormonal bacteria and biocontrol bacteria, specifically: a mixture of bacterial agents obtained from the expansion of the following four strains: Bacillus mycoides Gnyt1 strain, the preservation number is CCTCC M 2017177; Bacillus subtilis The Bacillus subtilis FX2 strain has a preservation number of CCTCC M 2017178; the Bacillus subtilis PBRS2 strain has a preservation number of CCTCC M 2017179; and the Bacillus subtilis LSH11 strain has a preservation number of CCTCC M 2017180.

[0040] Among them, the Bacillus mycoides Gnyt1 strai...

Embodiment 2

[0048] The using method of the hydroponic cucumber culture fluid additive of the present application is:

[0049] A: The composite microbial bacterial liquid prepared in Example 1.

[0050] B: Full amount of nutrient solution, using Japanese garden formula, the ingredients are as follows:

[0051] Major elements: calcium nitrate tetrahydrate 945 (mg / L); potassium nitrate 809 (mg / L);

[0052] Ammonium dihydrogen phosphate 153(mg / L); Magnesium sulfate heptahydrate 493(mg / L);

[0053] Trace elements: disodium edetate 27.8 (mg / L); ferrous sulfate heptahydrate 37.2 (mg / L); boric acid 2.86 (mg / L); manganese sulfate tetrahydrate 2.13 (mg / L);

[0054] Zinc sulfate heptahydrate 0.22 (mg / L); Copper sulfate pentahydrate 0.08 (mg / L);

[0055] Ammonium molybdate tetrahydrate 0.02 (mg / L).

[0056] 2. How to use:

[0057] (1) When cultivating cucumber seedlings, the nutrient solution adopts 1 / 2 amount of Japanese garden formula, and no compound microbial bacterial solution is added;

...

Embodiment 3

[0065] A hydroponic cucumber culture solution provided by the present invention contains a variety of beneficial microorganisms. By optimizing the concentration and adding time, it can provide a good growth environment for hydroponic cucumbers, improve the yield and quality of cucumbers, and reduce the cost of hydroponic vegetables. The operation method is simple, the cost is low, and the result is reliable. The specific experiment is as follows:

[0066] When the cucumber enters the spreading period, different nutrient solution formulas are used for comparative experiments, and the experiment is divided into seven groups: the first group: the control group: the full amount of Japanese garden formula nutrient solution, without compound microbial bacterial solution; the second group: Full amount of Japanese garden formula nutrient solution + 1.5% microbial bacterial solution;

[0067] The third group: full amount of Japanese garden formula nutrient solution + 1.0% microbial ba...

Abstract

The invention provides a compound microorganism bacteria solution, which is formed by mixing bacteria agents obtained by enlargement culture of the following four bacterial strains: a Bacillus mycoides Gnyt1 bacterial strain of which the collection number is CCTCC M 2017177, a Bacillus subtilis FX2 bacterial strain of which the collection number is CCTCC M 2017178, a Bacillus subtilis PBRS2 bacterial strain of which the collection number is CCTCC M 2017179 and a Bacillus subtilis LSH11 bacterial strain of which the collection number is CCTCC M 2017180. The microorganism bacteria solution can improve the absorption capacity and of plant root systems for nutrient elements and improve disease resistance, the yield and the quality of hydroponic culture Cucumis sativus L., and vegetable hydroponic culture cost is lowered.

Description

technical field [0001] The invention relates to a compound microbial bacterial liquid and its application in hydroponic cucumbers. Background technique [0002] Hydroponics is carried out under a relatively controllable environment. Compared with traditional soil cultivation, it has the advantages of controllable nutrient supply and environmental factors, high product safety, high yield, and better taste and quality. Therefore, hydroponic vegetables are regarded as a kind of high-grade vegetables and safe vegetables in China and many countries in the world. However, due to relatively complicated management and unsatisfactory yields, the production benefits have not yet reached the expected level. There are two main problems: First, hydroponic vegetables are grown in nutrient solution, which does not have the same level of soil as in traditional soil cultivation. Therefore, the control of the concentration of nutrient solution, the ratio of various nutrients, pH and temperat...
