Problems solved by technology

Various formulas in the prior art still have problems such as unbalanced nutritional elements and single function
[0003] Furthermore, in the prior art, there are fertilizers that contain comprehensive nutrients, but the fertilizer itself is easy to harden, and the root cause of fertilizer agglomeration is water. How to inhibit the chemical reaction of water release inside the fertilizer or set up water-blocking fertilizers on the surface of fertilizer particles Films, etc., so as to prevent or reduce the agglomeration of fertilizers has become an urgent problem in the fertilizer industry
[0004] Zinc is an essential micronutrient, usually applied in the form of simply ground zinc oxide, which is difficult to achieve even distribution in the roots of the crop; and has low solubility, resulting in low zinc utilization

Embodiment 1

[0039] A multifunctional long-acting fertilizer, comprising 40 parts by weight of urea, 20 parts of superphosphate, 15 parts of potassium sulfate, 15 parts of nanoscale magnesium oxide, 15 parts of nanoscale tourmaline, 8 parts of micronutrient elements, 0.1 Surfactant, 0.05 part of seaweed glucan, 0.05 part of pine algae, 0.3 part of zinc ammonium phosphate, 0.1 part of Korean pine polyphenol.

Embodiment 2

[0041] A multifunctional long-acting fertilizer, comprising 45 parts by weight of urea, 25 parts of superphosphate, 15 parts of potassium sulfate, 10 parts of nanomagnesia, 15 parts of nano tourmaline, 8 parts of micronutrients, 0.05 parts of Surfactant, 0.05 part of seaweed dextran, 0.05 part of pine algae, 0.1 part of zinc ammonium phosphate, 0.05 part of Korean pine polyphenol.

Embodiment 3

[0043] A kind of multifunctional long-acting fertilizer, by weight, comprises 45 parts of urea, 25 parts of superphosphate, 15 parts of potassium sulfate, 10 parts of nanometer magnesium oxide, 15 parts of nanometer tourmaline, 8 parts of micronutrient elements, 0.1 Surfactant, 0.1 part of seaweed dextran, 0.1 part of pine algae, 0.5 part of zinc ammonium phosphate, 0.2 part of Korean pine polyphenol.

[0044] The invention can be used not only as solid fertilizer, but also as liquid fertilizer. When the fertilizer of the present invention is used as a solid fertilizer, it can be prepared by a conventional solid fertilizer preparation method. Preferably, it is obtained by weighing according to the ratio of raw materials, crushing and mixing. When the fertilizer of the present invention is used as a liquid fertilizer, the preparation method of the conventional liquid fertilizer can be used. Preferably, it is weighed according to the ratio of raw materials, and after crushing an...

Abstract

The invention relates to multi-functional controlled availability fertilizer, which is prepared from the following components in parts by weight: 70 to 80 parts of nitrogen phosphorus and potassium basal fertilizer, 10 to 35 parts of medium nutrient elements, 2 to 8 parts of micronutrients, 0.05 to 0.1 part of surfactant, 0.05 to 0.1 part of seaweed glucan, 0.05 to 0.1 part of codium fragile, 0.1 to 0.5 part of ammonium zinc phosphate and 0.05 to 0.2 part of pine polyphenols. The multi-functional controlled availability fertilizer is compounded in formula, has a variety of effects, elements such as nitrogen, phosphorus and potassium, medium nutrient elements such as magnesium and boron, and micronutrients such as copper, cobalt and zinc can meet a variety of nutritions needed by the crop growth, and the yield and the quality of crops are improved; the ammonium zinc phosphate and copper, cobalt and zinc micronutrients nanocrystal particles are dissolved slowly to release nutrient cations, and the transport efficiency of nutrient elements is greatly improved.

Description

technical field [0001] The invention relates to a multifunctional long-acting fertilizer. Background technique [0002] Macronutrients, mesonutrients and micronutrients in soil, each of which is essential for crops. Various formulas in the prior art still have problems such as unbalanced nutritional elements and single function. [0003] Further, in the prior art, there are fertilizers that contain comprehensive nutrients, but the fertilizer itself is easy to harden, and the root cause of fertilizer agglomeration is water. How to inhibit the chemical reaction of water release inside the fertilizer or set up water-blocking fertilizers on the surface of fertilizer particles Films, etc., so as to prevent or reduce the agglomeration of fertilizers has become a problem that the fertilizer industry needs to solve urgently. [0004] Zinc is an essential micronutrient and is usually applied in the form of simply ground zinc oxide, which is difficult to achieve even distribution in...
