The invention relates to the technical field of fertilizers, in particular to a plant immune type direct-spraying liquid compound fertilizer and a preparation method thereof.

Background

The fertilizer is an essential substance for promoting plant growth and increasing yield, and is also one of important conditions for agricultural production development. At present, common fertilizers on the market are high-concentration solid fertilizers with single components, such as urea, nitrophosphate fertilizers and the like. However, these solid fertilizers can only provide a large amount of nutrient elements such as nitrogen, phosphorus, potassium and the like, and almost do not contain medium elements and trace elements, so that the lodging resistance and the pest and disease resistance of crops are low, the solid fertilizers are difficult to dissolve and absorb, digging and burying fertilizers are often needed during fertilization, even in regions with underdeveloped agriculture such as mountainous regions and the like, facilities such as drip irrigation, sprinkling irrigation and the like are not perfect, the fertilization needs rainwater and ditching in advance, and the fertilization is difficult. Meanwhile, because labor force is increasingly lacking and labor cost is high, the fertilization cost is increased, and economic losses are caused to farmers and growers.

Therefore, how to provide a liquid compound fertilizer with simple fertilization and comprehensive nutrition is a problem which needs to be solved urgently by the technical personnel in the field.

Disclosure of Invention

In view of the above, the invention provides a plant immune type direct-drenching liquid compound fertilizer and a preparation method thereof, wherein large, medium and trace elements in organic and inorganic nutrition and a plant sterilizing immunizing agent are integrated in the liquid compound fertilizer, and the liquid compound fertilizer can be directly drenched without digging a pit, thereby greatly improving the labor efficiency and avoiding the labor operation from being complicated.

Preferably, the chelating agent is one of EDTA and citric acid.

Preferably, the trace elements are one or a mixture of more of zinc heptahydrate, manganese sulfate, ferrous sulfate, boric acid and magnesium nitrate.

Preferably, the activated organic nutrient solution is an active biological organic nutrient solution obtained by acidifying organic wastes with dilute nitric acid, oxidizing and reducing with hydrogen peroxide solution, settling and filtering, and fermenting with EM bacteria. .

Preferably, the potassium fertilizer is one or a mixture of potassium nitrate and potassium tripolyphosphate.

Preferably, the nitrogen fertilizer is urea ammonium nitrate solution or urea.

Preferably, the concentration of the potassium hydroxide solution is 30 to 70 wt%.

2. the product has comprehensive nutrition, and the major and medium trace elements of organic and inorganic solutions and the sterilization type plant immunizing agent are fully and harmoniously dissolved into a whole, so that the nutrition problem of multiple crops can be solved once when the product is used by a planting user, and the labor burden is reduced;

3. in the production process, the mutual proportion of potassium nitrate, potassium tripolyphosphate, urea ammonium nitrate solution and other raw materials is adjusted, so that NPK (nitrogen-phosphorus-potassium) content products with different proportions, such as a high-nitrogen type product, a high-potassium type product and the like, can be manufactured, and the nutritional requirements of different crops in different periods can be met.
