Synchronous nutrition fertilizers, preparation methods thereof and applications thereof

Abstract

The invention discloses synchronous nutrition fertilizers, preparation methods thereof and applications thereof. The synchronous nutrition fertilizers comprise four formulas consisting of a high nitrogen formula, a high nitrogen potassium formula, a high potassium formula and an equalization formula, and the synchronous nutrition fertilizers of the four formulas respectively comprise a base fertilizer and a resin coating controlled release component adapted to the base fertilizer. The synchronous nutrition fertilizers of the invention can be applied to the one-time fertilizing of short-growth period field crops or the less-time afterfertilizing of long-growth period or perennial economic crops. The preparation methods of the invention not only allow the nutrient proportion of the fertilizers to satisfy demands of crops, but also allow the speed, the quantity, the proportion of nutrition elements of nutrients in the fertilizers to be controlled to basically fit the demands of nitrogen, phosphor and potassium of the crops with various growth periods. An organic cooperation of the fertilizers of the four base formulas of high nitrogen, high nitrogen potassium, high potassium, and equalization with the resin coating controlled release component is provided in the invention to solve a present limitation that one formula fertilizer only corresponds with the nutrition demands of one or one type crop.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and specifically relates to a preparation technology of formula fertilizer, in particular to a synchronous nutrient fertilizer and a preparation method thereof. Background technique [0002] So far, there is no research report on the synchronous nutrient fertilizer system that the rate of fertilizer supply, the amount of fertilizer supply (N, P and K ratio) are basically consistent with the crop demand. According to the available information, international and domestic related fertilizers mainly include controlled-release fertilizers and formula fertilizers based on ordinary fertilizers. The status and deficiencies of these two types of fertilizers are as follows: [0003] (1) Ordinary formula fertilizer [0004] Ordinary formula fertilizers are based on soil tests and field experiments, according to the law of crop fertilizer requirements, soil fertilizer supply performance and f...

AI Technical Summary

Problems solved by technology

However, due to the defect in the guiding ideology of this type of fertilizer design, that is, most of the common formula fertilizers are designed and manufactured according to the nutritional requirements and nutritional laws of the crops throughout their life, and are suitable for a lifetime of special formula fertilizers, resulting in the fertilizer efficiency of the current common formula fertilizers. The main vegetative phases do not coincide, so they cannot act as a vehicle for balanced fertilization

[0005] The main problem is that the common formula fertilizer is made of various single substance granular fertilizers and (or) compound fertilizers as raw materials. It is a water-soluble fertilizer. After being applied to the soil, the nutrient supply rate is fast, and it is easy to lose with rainfall or irrigation. Not only the utilization rate of fertilizer is low, but also cause serious arable land quality degradation and environmental problems

But this patented technology can only solve the simplified fertilization technology of tobacco, a special crop

The controlled-release formula fertilizer cannot be adapted to each of the three main nutrient stages of the crop life, but only to a certain stage, and in fact it cannot solve the problem of synchronizing the supply of nutrients from fertilizers and the needs of crops
