Problems solved by technology

However, the organic matter content in the formula of the special fertilizer for rice in this invention is small, which cannot continuously improve the paddy field; secondly, the bio-silicon fertilizer is applied once, and it is easy to cause nutrient loss, and the overall nutrient utilization rate needs to be improved

Embodiment 1

[0057] Embodiment 1 makes 30% (15-6-9) the special-purpose alkaline fertilizer for paddy rice of persistent effect improving soil. Take each component by the following parts by weight:

[0058]

[0059] The above-mentioned solid components crushed to 80-100 mesh are sent to the mixer to stir and mix evenly, and the steam is passed into the granulator for granulation: the granulated material is sent to the dryer for drying, and then sieved, Unqualified large-grained materials are crushed and returned to the granulator for re-granulation with fine powder; qualified materials are transported to the second-stage granulator for spraying with a 3% polyglutamic acid solution, and under the action of fertilizer granules preheating, The polyglutamic acid forms a film on the surface of the fertilizer granules, and after cooling, metering and packaging, the finished product of alkaline fertilizer for rice with 30% (15-6-9) sustained effect for soil improvement is obtained. That is, t...

Embodiment 2

[0060] Embodiment 2 Make 34% (18-8-8) special alkaline fertilizer for rice with persistent effect improving soil. Take each component by the following parts by weight:

[0061]

[0062]

[0063] The above-mentioned solid components crushed to 80-100 mesh are sent to the mixer to stir and mix evenly, and the steam is passed into the granulator for granulation: the granulated material is sent to the dryer for drying, and then sieved, Unqualified large-grained materials are crushed and returned to the granulator for re-granulation with fine powder; qualified materials are transported to the second-stage granulator for spraying with a 4% polyglutamic acid solution. Glutamic acid forms a film on the surface of the fertilizer granules, and after cooling, metering and packaging, the finished product of alkaline fertilizer for rice with 34% (18-8-8) sustained effect for soil improvement is obtained. That is, the total nutrient content is 34%, and the nitrogen, phosphorus, and p...

Embodiment 3

[0064] Embodiment 3 makes 33% (15-6-12) the special alkaline fertilizer for paddy rice of persistent effect improving soil. Take each component by the following parts by weight:

[0065]

[0066] The above-mentioned solid components crushed to 80-100 mesh are sent to the mixer to stir and mix evenly, and the steam is passed into the granulator for granulation: the granulated material is sent to the dryer for drying, and then sieved, Unqualified large-grained materials are crushed and returned to the granulator for re-granulation with fine powder; qualified materials are transported to the second-stage granulator for spraying with 2% polyglutamic acid solution, and under the action of preheating the fertilizer granules, polyglutamic acid The acid forms a film on the surface of the fertilizer granules, and after cooling, metering and packaging, the finished product of the special alkaline fertilizer for rice with a sustained effect of 33% (15-6-12) for soil improvement is obt...

Abstract

The invention relates to special alkaline rice fertilizer capable of modifying soil persistently and a production process thereof. The special alkaline rice fertilizer comprises urea or ammonium chloride, monoammonium phosphate and potassium chloride, wherein the nutrient content of nitrogen, phosphorus and potassium is larger than or equal to 30%. The special alkaline rice fertilizer further comprises organic fertilizer, silicon-calcium-potassium fertilizer and polyglutamic acid solution. The invention further provides the production process and an application method of the special alkaline rice fertilizer. The special alkaline rice fertilizer contains inorganic macroelements, medium elements of calcium and magnesium are added, and different kinds of organic fertilizer are properly matched, so the fertilizer can meet the demands for nutrients for rice growth, the pH value of the soil can be increased, the soil structure can be improved constantly, and the utilization rate of the fertilizer can be increased.

Description

technical field [0001] The invention belongs to the field of fertilizer production, and relates to a special alkaline fertilizer for rice with sustained effect for soil improvement and a production process thereof. Background technique [0002] Soil degradation refers to the process of soil quality and productivity decline caused by the irrational use of soil by humans. There are mainly erosion degradation, soil acidification, pollution degradation, fertility degradation and biological degradation. At present, with the increasingly prominent contradiction between population and environmental resources, soil degradation has become a major global problem. As an important aspect of soil degradation, soil acidification accelerates the increase of soil acidity and the leaching of a large number of nutrients, resulting in the decline of soil fertility and seriously affecting the growth of crops. Aiming at the main obstacle factors of low- and medium-yield soil in the main produc...
