Description
Technical Field
The invention belongs to the technical field of agricultural fertilizers, and particularly relates to a phosphite multifunctional water-soluble fertilizer and a preparation method thereof.
Background
Phosphite can excite the disease-resistant immune system of plants to enable crops to generate continuous immunity to pathogenic bacteria, is a new way for maintaining plant health and preventing and treating diseases, is proved to have the effects of increasing yield and resisting diseases to the crops, and has been widely accepted as a bactericide in the aspect of preventing and treating oomycete fungi. However, the concept of phosphite as a source of phosphorus for plant nutrition has been controversial because plants absorb mainly phosphate ions and it takes a long time for phosphite to oxidize into phosphate. Phosphites have their unique advantages in plant nutrition. The phosphorus of 5 valence in the phosphate can be only transported upwards in the xylem, the phosphorus of 3 valence of the phosphite can be transported in the xylem and the phloem in a double channel way, the absorption speed is faster than that of the phosphorus in the phosphoric acid state, the transportation and the absorption of nutrition are accelerated, and the phosphate fertilizer has the effects of promoting root growth, promoting flower growth, promoting fruit setting, improving the solid content of fruits and the like. Phosphites, when applied to soil, are much less likely to be adsorbed and immobilized by soil minerals than phosphates, and increase the mobility of phosphorus in the soil. And as an effective complexing agent, phosphite can be complexed with various metal elements such as K, Ca, Zn, Mo, Mn and the like, so that the effectiveness of the metal elements is improved.
Phosphite has been widely popularized and applied abroad, and in the nineties, bactericides such as potassium phosphite, ammonium phosphite, sodium phosphite, aluminum phosphite and the like are in the market, and the phosphite is also registered as a fertilizer in countries such as the united states, the english, the french, the germany, the spanish, the italy and the like, and enterprises in China register the phosphite as a pesticide or a fertilizer. The patent "application of potassium dihydrogen phosphite in preparing bactericidal foliar fertilizer" (Chinese patent publication No. CN1826899A) is prepared by adding potassium dihydrogen phosphite into "Soyi Er foliar fertilizer" and mixing. Because the antibacterial synergistic effect of the phosphite brings energy-saving and emission-reducing effects to the environment, the American environmental protection agency classifies the phosphite and phosphite products as an environmental protection biological agent, and is the only inorganic growth hormone at present.
Humic acid is a mixture of organic high molecular compounds containing various functional groups, which is accumulated by organic substances (animal and plant residues) through a series of processes of microbial decomposition and transformation and geochemistry, has the effects of promoting the growth and development of crops, preventing and resisting diseases, enhancing the stress resistance of the crops, increasing the yield, improving the quality of agricultural products, improving the physical and chemical properties of soil, enhancing the fertilizer efficiency and the like, and is a high-quality and high-efficiency biological stimulant.
The phosphite is oxidized into the phosphate which needs a long time and can not directly replace the phosphate to become the fertilizer, but the phosphite can excite the disease-resistant immune system of the plant, thereby proving that the humic acid has the effects of increasing the yield and resisting diseases for crops, and the humic acid is high-quality and high-efficiency biological stimulin and has five effects of improving soil, enhancing fertilizer efficiency, stimulating growth, promoting stress resistance, improving quality and the like. Therefore, the phosphite is combined with humic acid, phosphate and major elements, secondary elements and trace elements which are necessary for plants, and better effects of promoting the growth and development of crops, preventing diseases, resisting diseases, enhancing the stress resistance of the crops, increasing the yield and improving the quality of agricultural products can be achieved. Therefore, the invention provides a phosphite multifunctional water-soluble fertilizer and a preparation method thereof, the invention is a combination of phosphite, phosphate, activated humic acid and nutrient elements, can enhance the antibacterial function and physiological regulation function, meets the requirements of plants on the nutrient elements, has various effects of disease resistance, disease prevention, nutrition, stress resistance and the like, and has wide market prospect.
