Description

Technical Field

[0001] The invention relates to the technical field of water-soluble fertilizers, in particular to a water-soluble fertilizer containing natamycin and an application method thereof. Background Art

[0002] Water-soluble fertilizer is a kind of multi-component compound fertilizer that can be completely soluble in water. It can dissolve in water quickly and is more easily absorbed by crops. Its absorption and utilization rate is relatively high. It refers to liquid or solid fertilizer that can be used for irrigation, foliar fertilization, soilless cultivation, seed soaking and root dipping after being dissolved or diluted in water.

[0003] For example, the Chinese patent of announcement number CN106699428A (water-soluble fertilizer for bitter melon) includes water-soluble fertilizer for seedling stage and water-soluble fertilizer for fruiting stage, and the water-soluble fertilizer for seedling stage contains 54-65 parts of nitrogen, phosphorus and potassium in total, 0.5 parts of magnesium, 0.5 parts of secondary elements, EDTA-Cu, EDTA-Fe, EDTA-Mn, EDTA-Zn, molybdenum and 0.5092 parts of boron in total, and the water-soluble fertilizer for fruiting stage contains 63-75 parts of macroelements, 0.3 parts of magnesium, 0.5 parts of secondary elements, EDTA-Cu, EDTA-Fe, EDTA-Mn, EDTA-Zn, molybdenum and 0.5092 parts of boron in total. The present invention can provide a boost for the growth of bitter melon fruit and enhance the disease resistance of crops, so that the quality of bitter melon is good and the yield is high.

[0004] Existing water-soluble fertilizers have poor fungal contamination prevention effects. After fertilization, the product is easily damaged by fungal infection, resulting in poor fertilization effect and low survival rate. To this end, we provide a water-soluble fertilizer containing natamycin and an application method thereof. Summary of the Invention

[0005] The object of the present invention is to provide a water-soluble fertilizer containing natamycin and an application method thereof, so as to solve the problem proposed in the above background art that the existing water-soluble fertilizer has poor anti-fungal contamination effect and the product is easily damaged by fungal infection after fertilization, resulting in poor fertilization effect and low survival rate of the product.

[0006] To achieve the above object, the present invention provides the following technical solution: a water-soluble fertilizer containing natamycin, comprising the following raw materials in the following mass percentage ratios: 65% nutrient elements; 8% secondary elements; 0.08% natamycin; 0.1% EDTA chelated iron, zinc and boron; 0.2% polysorbate; 0.5% surfactant; 0.3% stabilizer; 0.02% vitamin C; 22.8% water; 1% cosolvent; and 2% pH regulator.

[0007] Preferably, the nutrient element is one or more of potassium nitrate, ammonium dihydrogen phosphate and urea.

[0008] Preferably, the secondary element is one or more of magnesium sulfate and calcium nitrate.

[0009] Preferably, the surfactant is one or more of alkyl glycoside, sodium dodecylbenzenesulfonate and sucrose ester.

[0010] Preferably, the stabilizer is one or more of citric acid, maltodextrin and urease inhibitor.

[0011] Preferably, the cosolvent is one or more of propylene glycol, amino acid and talc.

[0012] Preferably, the pH regulator is one or more of potassium dihydrogen phosphate, triammonium citrate and ferrous sulfate.

[0013] Preferably, the pH regulator maintains the solution weakly acidic, with the pH value maintained between 5.5-6.5.

[0014] Preferably, the pH regulator is added in batches and in a quantitative manner.

[0015] Preferably, a method for applying a water-soluble fertilizer containing natamycin comprises the following steps:

[0016] Step 1: Pour the nutrients and intermediate elements into the mixing container and add water to mix;

[0017] Step 2: Take out half of the natamycin, add a small amount of water to mix and dilute until there is no lumps, pour it into the mixing container, and mix it with the previous mixed liquid;

[0018] Step 3: Then add EDTA chelated iron, zinc and boron, surfactant, stabilizer, cosolvent, water and the remaining natamycin to the mixing container in sequence. If the mixture precipitates, continue to add water until there is no precipitation;

[0019] Step 4: Then add vitamin C and polysorbate and mix, add the remaining water, and add the pH regulator little by little, while adding and mixing until the pH is adjusted to the required range;

[0020] Step 5: Pour it into a spray container and spray it on the surface of the crops until it is moist but not dripping. Avoid strong light periods and spray in the early morning or evening. Do it once every 10-15 days and spray twice in a row.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The present invention adds natamycin, which is a natural antifungal agent that works by inhibiting the synthesis of fungal cell membranes. Natamycin is a natural antifungal agent produced by the fermentation of Streptomyces. It inhibits the growth and reproduction of pathogenic bacteria by destroying the ergosterol structure in the fungal cell membrane. By incorporating natamycin into the water-soluble fertilizer, it not only has the characteristics of easy absorption, high utilization rate and resource saving of traditional water-soluble fertilizers, but also adds a strong inhibitory ability against molds and yeasts, thereby improving the survival rate of crops. In addition, water-soluble fertilizers containing natamycin usually have good water solubility and solution stability, will not precipitate, and the solution is clear and odorless, and does not affect the original color and flavor of the crops. This makes the fertilizer particularly suitable for the cultivation of edible crops, which can not only ensure food safety but also improve the disease resistance and growth performance of crops, thereby solving the problem that the existing water-soluble fertilizers have poor anti-fungal contamination effect and the product is easily damaged by fungal infection after fertilization, resulting in poor fertilization effect and low survival rate of the product.

[0023] (2) Spray the mixture on the surface of crops until the surface is moist but not dripping. Avoid strong light periods and spray in the early morning or evening to avoid waste caused by excessive spraying and damage to crops, thereby increasing the survival rate. Avoiding strong light periods can prevent strong sunlight from causing rapid evaporation and affecting the fertilization effect. Choosing early morning or evening can reduce the use of waste, reduce costs, and increase utilization. BRIEF DESCRIPTION OF THE DRAWINGS
