Technical Field

The invention belongs to the technical field of crop compound fertilizers, and particularly relates to a chelated controlled-release compound fertilizer and a preparation method thereof.

Background

China is a big agricultural country and also a big country for producing and using chemical fertilizers. The use of a large amount of chemical fertilizers promotes the improvement of grain yield in China and greatly promotes the development of agriculture in China. However, in the process of using the fertilizer, most people misunderstand that the compound fertilizer containing N.P.K. is the universal fertilizer, so that the use of other fertilizers is ignored. The consequence of this is that the soil is hardened seriously, the pH value exceeds the standard, the quality of crops is reduced, the farming cost of farmers is increased, other elements required by the growth of the crops are lacked in a large quantity, and therefore the yield of the crops does not reach the expected yield of fertilization, or diseases and insect pests easily appear in the later growth process. Therefore, the novel chelating controlled-release compound fertilizer is developed to supplement the requirements of other crops on the basis of ensuring the reasonable proportion of nitrogen, phosphorus and potassium

Trace elements are needed, so that the disease of crops caused by the lack of trace elements is greatly relieved.

Urea: is the nitrogen fertilizer with the highest nitrogen content at present. Urea is a high-concentration nitrogen fertilizer, belongs to a neutral quick-acting fertilizer, and can also be used for producing various compound fertilizers. No harmful substance is left in the soil, and no adverse effect is caused after long-term application. Urea is suitable for use as a base fertilizer and a top dressing, and is sometimes used as a seed fertilizer. The urea is suitable for all crops and all soils, can be used as a base fertilizer and a top dressing, and can be applied to both dry and paddy fields. Urea can promote cell division and growth, and make branches and leaves grow luxuriantly.

Monoammonium phosphate: good chemical stability and good compatibility with ammonium sulfate, potassium dihydrogen phosphate and the like. Is one of the main varieties of high-concentration phosphorus compound fertilizers. The product is generally used as a top dressing, and is also the most main basic raw material for producing ternary blended fertilizer and BB fertilizer; the product is widely applicable to various grain crops and economic crops. Application as a fertilizer during crop growth is most suitable, being acidic in the soil, and also being superior to other fertilizers in alkaline soil.

Ammonium sulfate: it is mainly used as fertilizer and is suitable for various soils and crops. A high-quality nitrogen fertilizer (commonly called "fertilizer field powder") is suitable for general soil and crops, and can make branches and leaves grow vigorously, raise fruit quality and yield, and raise the resistance of crops to disasters, so that it can be used as base fertilizer, additional fertilizer and seed fertilizer.

Amino acid chelated zinc: the amino acid chelated zinc is a zinc structural form in which zinc ions are embedded between two amino acid molecules. Two amino acid molecules clamp a zinc ion like crab pincers to form an ultra-stable chelating structure. The amino acid can be directly absorbed by the plants to stimulate the growth of the plants, and the amino acid can be directly utilized by the plants under the condition of no photosynthesis; when the amino acid medium trace element chelate is used as a chelate, metal ions can be protected from generating side reactions with other substances, and the chelate can be absorbed and utilized by crops after the metal ions reach the required parts of the plants, so that the amino acid medium trace element chelate is an organic medium trace element fertilizer with excellent performance, low price and moderate chelating constant, and can effectively solve the contradiction between balanced fertilizer preparation and balanced absorption of the crops.

Potassium sulfate: the potassium sulfate is colorless crystals, has small hygroscopicity, is not easy to agglomerate, has good physical properties, is convenient to apply and is a good water-soluble potassium fertilizer.

Potassium dihydrogen phosphate: the fertilizer is used as a high-efficiency phosphorus-potassium compound fertilizer in agriculture; the potassium dihydrogen phosphate product is widely suitable for various types of cash crops, grains, melons, fruits, vegetables and almost all types of crops. The actual application effect of various crops in various regions proves that the monopotassium phosphate has a plurality of excellent effects of remarkably increasing both production and income, improving quantity and optimizing quality, resisting lodging, resisting diseases and insect pests, preventing and treating premature senility and the like, and has the effect of overcoming the insufficient nutrition caused by the reduction of the aging and absorption capacity of the root system in the later growth period of the crops.

Compound sodium nitrophenolate: has the functions of promoting cell protoplasm flow, improving cell activity, accelerating plant growth and development, promoting root growth and seedling strengthening, protecting flower and fruit, bearing fruit and expanding, improving yield, enhancing stress resistance and the like.

Straw: the straw is a general term of stem leaf (ear) part of mature crops. Typically refers to the remainder of the wheat, rice, corn, potatoes, oil, cotton, sugar cane and other crops (typically roughages) after harvesting the seed. The straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium, organic matters and the like, is a multipurpose renewable biological resource, and is a coarse feed. It features high coarse fibre content (30-40%), and lignin content. The straw bio-fertilizer produced by the straw has higher fertilizer efficiency. The straw is used as a fertilizer to be applied to farmlands through comprehensive utilization, and the method is an effective method for supplementing and balancing soil nutrients and improving soil.

Bean pulp: is a byproduct obtained after soybean oil is extracted from soybeans. The bean pulp is a good organic fertilizer raw material.

Vinasse: the vinasse is a good organic fertilizer, and can effectively improve weak acid state of soil by mixing the vinasse into the soil, so that small particles of the soil are condensed to improve the granular structure of the soil, and the permeability of fertilizer, water and air of plant roots and the extension of the roots are facilitated.

Biological agent: the function is as follows: the soil fertility is improved, organic and inorganic nutrients in soil are activated, the fertilizer efficiency is improved, the crop circulation is promoted, the long-acting absorption and utilization are realized, and the roots are increased, the seedlings are strengthened and the fruits are full; improving soil, improving soil aggregate structure, eliminating hardening, improving water and fertilizer retention capacity, and resisting drought, stress, cold and lodging; the soil conditioner can be used continuously, and can improve the micro-ecological environment of soil. Eliminate soil hardening, neutralize pH value and reduce heavy metal and salt and alkali toxicity in soil.

Plant growth regulator: a plant growth regulator is a kind of agricultural chemicals for regulating plant growth and development, including artificially synthesized compound and natural plant hormone extracted from organism. Its existence can influence and effectively regulate and control the growth and development of plants, including a series of plant life processes from cell growth, division, rooting, germination, flowering, fructification, maturation and abscission.

The invention takes nitrogen-based acid as a main organic compound fertilizer, and adds partial trace elements on the basis of reasonably proportioning nitrogen, phosphorus and potassium, thereby improving the utilization rate of major elements to different degrees and playing an important role in relieving diseases of crops caused by the lack of trace elements.
