Problems solved by technology

[0006] At present, all the methods of supplementing trace elements to plants on the market are to apply fertilizers containing corresponding metal elements. Long-term application will cause excessive deposition of metal ions in the soil, resulting in compaction and hardening of the soil, thus affecting the growth and development of subsequent season crops.

Embodiment 1

[0021] This example is a preparation example of chelated urea added with iminodisuccinic acid tetrasodium salt; the addition amount of the fertilizer synergist iminodisuccinic acid tetrasodium salt is 5‰ of the urea consumption.

[0022] The preparation method is:

[0023] Add the coloring agent into the stirring device, mix it with iminodisuccinic acid tetrasodium salt with a solid content of 40%, after the coloring agent is dissolved, stirred and dispersed evenly, use a metering pump to chelate the above solution at a rate of 5Kg synergist / ton The proportion of urea is evenly sent to the front inlet pipeline of the melting pump of the urea production line, and then enters the prilling tower for granulation, and finally obtains chelated urea.

[0024] The prepared chelated urea and ordinary urea were subjected to performance tests respectively, and the test data are shown in Table 1.

[0025] The performance test comparison of table 1 chelated urea and common urea

[0026] ...

Embodiment 2

[0028] This example is a preparation example of chelated urea-based compound fertilizer added with tetrasodium iminodisuccinate. 1 ton of chelated urine-based compound fertilizer contains the following ingredients:

[0029] Urea 276kg, potassium sulfate 310kg, ammonium phosphate 410kg, iminodisuccinic acid tetrasodium salt (solid) 4kg.

[0030] The preparation method is:

[0031] Add the coloring agent into the stirring device and mix it with the iminodisuccinic acid tetrasodium salt solution with a solid content of 40%. The ratio of 10Kg of tetrasodium iminodisuccinic acid solution in the medium is evenly sent to the front inlet pipeline of the drum of the urea-based compound fertilizer production line, and then enters the drum for granulation. The tetrasodium iminodisuccinic acid and coloring agent are mixed with other The materials (urea, potassium sulfate, ammonium phosphate and a small amount of water) are mixed evenly, and part of the materials are melted and bonded wi...

Embodiment 3

[0034] This embodiment is a preparation embodiment of the chelated water-soluble fertilizer added with tetrasodium iminodisuccinate. 1 ton of chelated water-soluble fertilizer contains the following components: urea 342kg, potassium nitrate 240kg, ammonium phosphate 410kg, iminodisuccinic acid tetrasodium salt (solid) 8kg. Manufacturing equipment and preparation method are with embodiment 1.

[0035] After testing, the chelated water-soluble fertilizer has met the requirements of the national quality standard.

Abstract

The invention discloses the application of iminodisuccinate as a fertilizer synergist. The iminodisuccinate is added to a basic fertilizer as a fertilizer synergist, and the basic fertilizer does not contain trace element supplements. As a fertilizer synergist, iminodisuccinate can activate a variety of fixed metal ions in the soil so that they can be absorbed by crops, without adding supplements containing trace elements, which reduces the The production cost and sales price reduce the burden on farmers; at the same time, the metal ion content in the soil is reduced, which effectively improves the problem of soil compaction caused by the large-scale application of fertilizers.

Description

technical field [0001] The invention relates to a new application of iminodisuccinate, in particular as a fertilizer synergist in basic fertilizers without trace element supplements. Background technique [0002] Calcium, magnesium, zinc, manganese, iron, copper and other elements are trace elements necessary for plant growth. Although these elements are not lacking in nature, they are generally less available for direct absorption and utilization by plants. The reason is that these elements are easily deposited as insoluble salts in the soil environment, or are immobilized by the adsorption of soil colloids. , resulting in inability to be absorbed by plants. In order to supplement trace elements to plants, there are two commonly used methods at present: one is to apply inorganic minerals containing corresponding trace elements to the soil, and the other is to spray chelate fertilizer on the leaves. [0003] The price of inorganic minerals is relatively low, and it can be ...
