Description
Technical Field
The invention belongs to the field of fertilizers, and particularly relates to a dihydro-jasmonic acid propyl ester polymerized phosphorus-potassium fertilizer and a preparation method thereof.
Background
The fertilizer contains a large amount of phosphorus and potassium elements, and the potassium mainly exists in an ionic state or soluble salts or is adsorbed on the surface of an protoplasm, but does not exist in the form of an organic compound; phosphorus is an important component of plant cell protoplasm, plays an important role in the synthetic transformation and transfer of plants in the plant, and the lack of phosphorus and potassium elements can have adverse effect on the growth of crops. Meanwhile, phosphorus and potassium elements can play a role in increasing fruit sugar and promoting the formation of fruit peel and pulp pigments so as to promote fruit coloring in the mature period of crops, after being absorbed by leaves and root systems, the phosphorus and potassium elements are transported in vascular bundle woody parts, the transportation speed is seriously influenced by transpiration, and when the transpiration effect is weakened in rainy days, the coloring effect is seriously reduced.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provides a dihydro-propyl jasmonate polymerized phosphorus-potassium fertilizer and a preparation method thereof, wherein the dihydro-propyl jasmonate is mixed with plant endogenous terpenoid and phosphorus-potassium elements, so that the problem of transportation blockage of mineral phosphorus-potassium elements in the phloem of a plant is solved; the propyl dihydrojasmonate and the phosphorus and potassium elements are mutually synergistic, so that the phosphorus and potassium elements can be conducted in the plant body through the phloem under the condition of weak transpiration such as rainy weather and the like in the crop coloring period, mineral substance nutrients are provided for plant coloring, and the coloring and sweetening effects are further increased.
The technical scheme of the invention is as follows:
the propyl dihydrojasmonate polymerized phosphorus-potassium fertilizer comprises the following raw materials in parts by weight: 520-580 parts of phosphorus-potassium element, 80-120 parts of dihydrojasmonate, 3-8 parts of plant endogenous extract, 1-2 parts of B vitamins, 40-60 parts of thioester and 290-300 parts of water.
The phosphorus-potassium element provides mineral nutrition required by growth and coloring of crops, and the ionic phosphorus-potassium nutrient elements are connected together through chemical bonds to form molecular substances by utilizing the interaction among plant endogenous extracts, B vitamins and thioester.
The propyl dihydrojasmonate has the promotion effect on fruit coloring and dry matter synthesis, and can be transported in the phloem of the vascular bundle as an organic component; when the dihydrojasmonic acid lactone is combined with plant endogenous terpenoid and phosphorus and potassium elements, the effects of the dihydrojasmonic acid lactone and the phosphorus and potassium elements can be mutually enhanced, so that the phosphorus and potassium elements can be conducted in the plant body through the phloem under the condition of weak transpiration such as rainy weather and the like in the crop coloring period, and mineral substance nutrients are provided for plant coloring.
Preferably, the feed comprises the following raw materials in parts by weight: 550 parts of phosphorus potassium element, 100 parts of dihydrojasmonate lactone, 5 parts of plant endogenous extract, 1 part of B vitamins, 50 parts of thioester and 294 parts of water.
Furthermore, the plant endogenous extract is a terpenoid, the terpenoid extracted from the plant endogenous extract can improve the photosynthesis of plant leaves, promote the metabolic cycle of plants and increase the disease resistance of the plants, and meanwhile, the terpenoid contains olefinic bonds with different saturation degrees and can be linked with ionic nutrient elements or other organic substances through atomic covalent bonds under the conditions of high temperature and high pressure to form a new molecular structure. The terpenoid is one or more of citral, menthol, farnesol and carotene; preferably, the terpenoid is citral.
Furthermore, the B vitamins can improve the cell function and promote the metabolic cycle of cell nutrients; the vitamin B group is vitamin B6, vitamin B6 not only improves cell function and promotes metabolism, but also decomposes under heating, and HCl is removed while H is removed when vitamin B6 is decomposed under heating2O generates ether substances. The ethers contain a large amount of alkyl and aryl, can quickly link other functional groups such as hydroxyl, phenolic hydroxyl and the like in the dihydrojasmonic acid propyl ester, and improve the long-chain stability of the nutrient molecules.
Further, the sulfur ester is thiodiglycol distearate. The thioester is an intermediate product in the ATP decomposition or synthesis process, contains high-energy chemical bonds, and meanwhile, the thioester can play a good role in protecting plant cells and has an antioxidant effect in a molecular long chain. The thiodiglycol distearate can protect the long chain form of the molecule from being oxidized, and the structure of the long chain of the molecule nutrition does not change at all, thereby ensuring that the long chain of the potassium dihydrogen jasmonate polymerized phosphorus and potassium does not deteriorate.
Furthermore, the adopted phosphorus and potassium element is a common raw material used for producing fertilizers in the current market, and the phosphorus and potassium element is potassium dihydrogen phosphate.
A preparation method of a dihydrojasmonic acid propyl ester polymerized phosphorus-potassium fertilizer comprises the following steps:
(1) weighing 520-580 parts of phosphorus-potassium element, 80-120 parts of dihydrojasmonate, 3-8 parts of plant endogenous extract, 1-2 parts of B vitamins, 40-60 parts of thioester and 290-300 parts of water for later use;
(2) adding water and dihydrojasmonate lactone into a reaction kettle, setting the temperature to be 40-50 ℃, heating and fully stirring for 10 min;
(3) adding the mixed phosphorus and potassium elements and the plant endogenous extract into a reaction kettle, setting the heating temperature to be 70-75 ℃, stirring until the phosphorus and potassium elements and the plant endogenous extract are completely dissolved, and continuously heating in the stirring process; sealing the reaction kettle, adjusting the pressure of the reaction kettle to be 500kpa, keeping the pressure unchanged, heating discontinuously in the reaction process, and stopping the reaction for 50-70 min until the solution is viscous;
