Synchronous nutrition fertilizers, preparation methods thereof and applications thereof

Abstract

The invention discloses a synchronous nutrient fertilizer and its preparation method and application. The synchronous nutrient fertilizer includes four formulations of high nitrogen, high nitrogen and potassium, high potassium or balance, and the synchronous nutrient fertilizers of the four formulations respectively include basic fertilizers and resin-coated controlled-release components compatible with the basic fertilizers. The synchronous nutrient fertilizer of the present invention can be applied to one-time fertilization of field crops with a short growth period or few times of topdressing fertilization to economic crops with a long growth period or perennials. The invention not only realizes that the fertilizer nutrient ratio meets the needs of crops, but further realizes that the nutrient supply speed, quantity, and ratio of nutrient elements in the fertilizer are controlled to basically match the requirements of nitrogen, phosphorus, potassium, etc. in each growth period of crops. Provides the organic combination of high nitrogen, high nitrogen potassium, high potassium and balanced four basic formula fertilizers and resin-coated controlled-release components, which solves the current limitation that one formula fertilizer only corresponds to one or one type of crop's lifetime nutritional needs .

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
