Downy mildew (Pseudoperonospora cubensis (berk. et cut.) Rostov) is one of the major diseases of vegetables, and downy mildew of the same vegetable is usually caused by the same species of downy mildew, which share common symptom characteristics and the same control method. The existing fertilizer is used as a main nutrient source of vegetables, and due to the influence of various factors such as climate, water source, soil texture, plant diseases and insect pests, the fertilizer artificially put into the ground cannot be completely absorbed by the vegetables, and many diseases of the vegetables are caused by lack of nutrition. The water-soluble fertilizer is a multi-element compound fertilizer capable of being completely dissolved in water, and compared with the traditional elemental fertilizer, common compound fertilizer and other fertilizers, the water-soluble fertilizer has the remarkable advantages of instant dissolution, high absorption rate, quick response, convenient application and the like, and is developed rapidly. The application of the water-soluble fertilizer to control the diseases is an effective way for replacing chemical pesticides to prevent and control downy mildew. With the social development, the agricultural development increasingly demands the requirements of no pollution, high efficiency and low labor force, so that the application mode of the novel water-soluble fertilizer is very necessary for vegetable planting. However, the following problems generally occur in the case of water-soluble fertilizers containing microbial agents: (1) the acidity of the prepared water-soluble fertilizer is not suitable for the growth of microorganisms; (2) the addition of microorganisms affects the quality of the water-soluble fertilizer, such as the content of water-insoluble substances; (3) it is difficult for microorganisms to stably survive in water-soluble fertilizers.

the microbial agent is in the form of spore powder, and the effective spore number in each gram of spore powder is 1 multiplied by 106Spores;
wherein the microbial agent is Monascus ruber (Monascus ruber), which is preserved in the China general microbiological culture Collection center in 2016 (11.3.11.11.4.9. 3.15746.
The preparation method of the water-soluble fertilizer for vegetable planting comprises the following steps:
firstly, mixing molasses fermentation liquor, calcium nitrate, monoammonium phosphate, potassium nitrate and magnesium nitrate, then adding a microbial agent to prepare a suspension, continuously stirring, controlling the stirring temperature to be 27 ℃, and stirring for 6 days, and uniformly stirring to obtain the fertilizer.
Example 8
Specific applications of the water-soluble fertilizers in examples 1-7 and comparative examples 1-3:
we examined the performance indexes of different water-soluble fertilizers, and the results are as follows (as shown in Table 1):
the specific test method is as follows: selecting a certain cucumber test point of Anhui Hefei, transplanting healthy cucumbers (in a seedling stage, cucumber seeds are purchased from Heifei Fengle Seiko GmbH, a variety of Fengle-Xiaofeilong) and then applying the water-soluble fertilizer, measuring the activity of microbial agent spores in the water-soluble fertilizer and the quality of the water-soluble fertilizer (according to a standard NY 2266 and 2012 medium-element water-soluble fertilizer), and then performing a downy mildew infection test in a fruiting stage of the cucumbers, observing the properties of the cucumbers and measuring the quality of the cucumbers.
TABLE 1
Tests show that (in combination with table 1), compared with comparative examples 1-3, the water-soluble fertilizers of examples 1-7 have remarkable improvement on the yield, quality and disease resistance of cucumbers; in examples 1 to 7, different contents of the components in the water-soluble fertilizer have different effects on the effect of the water-soluble fertilizer, wherein the water-soluble fertilizer prepared in example 7 has large differences in the significance of the indexes.
In conclusion, the microbial agent (monascus ruber) is introduced into the traditional vegetable fertilizer, the microbial agent can effectively enhance the anti-infection capacity of vegetables to downy mildew, and the microbial agent can utilize molasses fermentation liquor, calcium nitrate, urea ammonium nitrate solution, monoammonium phosphate, potassium nitrate, magnesium nitrate, yeast powder and polyglutamic acid in the water soluble fertilizer to ferment; the combination of the microbial agent and other raw materials in the water-soluble fertilizer can be stably stored in the water-soluble fertilizer and keep activity by a proper preparation method. Therefore, the water soluble fertilizer can effectively promote the growth of vegetables (cucumbers) and prevent and control the infection of downy mildew.
While the invention has been described in further detail in connection with specific embodiments thereof, it will be understood that the invention is not limited thereto, and that various other modifications and substitutions may be made by those skilled in the art without departing from the spirit of the invention, which should be considered to be within the scope of the invention as defined by the appended claims.
