Description
Technical Field
The invention belongs to the technical field of fertilizers, and particularly relates to a fertilizer for enhancing disease resistance of crops and a preparation method thereof.
Background
The fertilizer for enhancing disease resistance of crops is a fertilizer with a special formula, and aims to improve the resistance and immunity of crops to diseases. These fertilizers typically contain a variety of components, some of which promote plant growth and nutrient absorption, while also enhancing the immune system of the plant and making it more resistant to pathogen attack.
Publication (bulletin) number: CN101973812B discloses a tomato disease-resistant fertilizer composition. The fertilizer composition consists of urea, monoammonium phosphate, potassium sulfate or potassium chloride, gypsum, magnesium sulfate monohydrate, sodium bicarbonate, vitality element and attapulgite clay. The control experiment of the tomato disease-resistant fertilizer composition and the conventional fertilizer shows that the quantity and proportion of the root-knot nematodes of the tomatoes are obviously reduced, the control effect on the root-knot nematodes is obvious, the growth and development indexes of the tomatoes are effectively improved, the protective enzyme activity of the tomato leaves is improved, and the disease resistance of the tomatoes is obviously improved.
The problems of the prior art are: urea is a nitrogen source that can promote plant growth and development. However, urea is easily volatilized, resulting in nitrogen loss, and reducing the utilization efficiency of the fertilizer. Monoammonium phosphate is a fertilizer containing nitrogen and phosphorus, and is helpful for the development of plant root systems and the formation of flowers and fruits. However, the improper use of monoammonium phosphate at high concentration may cause accumulation of phosphorus in soil, resulting in environmental pollution. Attapulgite clay is a soil conditioner and is helpful for improving soil structure and keeping moisture. However, excessive use may result in poor soil drainage and poor air permeability.

(1) The fertilizer is suitable for crops to absorb nutrients: the acidic pH value of the stock solution is helpful for improving the soil environment, so that nutrients in the stock solution are easier to be absorbed and utilized by crops. For some crops that are acid soil-prone, lower pH values help to increase their growth and development.
(2) Inhibition of pathogen growth: the acidic environment has an inhibitory effect on the growth and reproduction of many pathogens. Lower pH values can reduce the activity of certain pathogenic microorganisms in the soil and reduce the risk of plant disease.
(3) Promote the solubility of nutrient elements: the acidic environment helps to increase the solubility of certain nutrients in the soil. In this way, the crop root system can more readily absorb these nutrients, thereby improving the nutrient absorption efficiency of the plant.
(4) The pesticide effect is improved: some pesticides are more effective in acidic environments. If the stock solution is used for disease control, the lower pH value can enhance the sterilization effect of the pesticide and improve the control effect.
Preferably, the pH of the stock solution obtained in step S3 is 4.2.
