Abstract
The application relates to the technical field of water-soluble fertilizers, and particularly discloses a liquid water-soluble fertilizer and a preparation method and application thereof. The liquid water-soluble fertilizer comprises the following raw materials in parts by weight: 70-110 parts of glycocyamine, 15-25 parts of trace elements, 40-60 parts of nitrogen source, 16-30 parts of alginic acid, 3-10 parts of chitosan oligosaccharide and 2-5 parts of stabilizer; the preparation method comprises the following steps: mixing glycocyamine, a nitrogen source, alginic acid and chitosan oligosaccharide uniformly, filtering, adjusting the pH of the filtrate, adding trace elements and a stabilizer into the filtrate, and mixing uniformly to obtain the liquid water-soluble fertilizer. The water-soluble fertilizer of liquid of this application through the synergism between the raw materials, has the absorption rate that improves water-soluble fertilizer and the advantage of fertilizer efficiency.
Description
Technical Field
The application relates to the technical field of water-soluble fertilizers, in particular to a liquid water-soluble fertilizer and a preparation method and application thereof.
Background
In the traditional agricultural production practice, crops grow naturally, and with the development of science and technology, the requirements of people on the crops are higher and higher, and fertilizers for the crops are used more and more frequently, wherein water-soluble fertilizers are one of the fertilizers.
The water-soluble fertilizer is a compound fertilizer containing nitrogen, phosphorus, potassium, calcium, magnesium, trace elements, amino acids, alginic acid and the like, which can be completely dissolved in water and is divided into a solid water-soluble fertilizer and a liquid water-soluble fertilizer in forms. The liquid water-soluble fertilizer is a quick-acting fertilizer, has good water solubility and no residue, can be completely dissolved in water, and can be directly absorbed and utilized by root systems and leaf surfaces of crops.
At present, the water-soluble fertilizer is widely applied to various crops such as vegetables, fruit trees, flowers, grains, cotton, oil and the like, but the water-soluble fertilizer has low absorption rate by the crops, and the fertilizer efficiency of the water-soluble fertilizer is influenced.
Disclosure of Invention
In order to improve the absorption rate and the fertilizer efficiency of the water-soluble fertilizer, the application provides a liquid water-soluble fertilizer and a preparation method and application thereof.
First aspect, the application provides a water-soluble fertilizer of liquid adopts following technical scheme:
a liquid water-soluble fertilizer comprises the following raw materials in parts by weight: 70-110 parts of guanidinoacetic acid, 15-25 parts of trace elements, 40-60 parts of nitrogen source, 16-30 parts of alginic acid, 3-10 parts of chitosan oligosaccharide, 2-5 parts of stabilizer and 400 parts of water 250-.
Through adopting above-mentioned technical scheme, the water-soluble fertilizer of liquid of this application, through the synergistic effect between each raw materials, is showing and is improvingThe fertilizer efficiency of the water-soluble fertilizer can improve the plant height, the dry weight of the beancurd sheets, the fruit setting number and the yield of the tomatoes, wherein the plant height of the tomatoes is 175cm, the dry weight of the beancurd sheets is 120-159g, and the fruit setting number is 128976-143456/hm 2 The yield is 15721-17564kg/hm 2 。
The glycocyamine can promote the photosynthesis of crops, is beneficial to the growth of the crops, can increase the content of sugar in the crops, can improve the absorption of the crops to phosphorus and potassium elements, improve the stress resistance of the crops, can also increase the content of chlorophyll of the crops, improve the activity of enzyme, promote the permeation of carbon dioxide, enhance the photosynthesis of the crops, and then improve the quality of the crops, thereby improving the fertilizer efficiency of the liquid water-soluble fertilizer.
The trace elements are mostly components or activators of enzymes and coenzymes in crops, and play important roles in promoting and regulating the synthesis of chlorophyll and protein, photosynthesis or metabolic process, absorption and utilization of nutrients such as nitrogen, phosphorus, potassium and the like.
