Abstract

The present invention is a kind of making method of composite fertilizer containing rare-earth elements, belong to the biological chemistry industrial circle, this composite fertilizer containing rare-earth elements be by plant-growth element and the organism such as nitrogen, phosphorus, potassium that need in a large number, with can improve Soil structure, plant-growth is played the rare earth nitrate element mechanically mixing of regulating effect, pulverizing is made, it can be good at overcoming plant and lacks nutrition, the poor growth phenomenon, also have obvious effect of increasing production simultaneously, reduce sprout term disease, improve the function of Soil structure.

Description

A kind of making method of composite fertilizer containing rare-earth elements

The present invention is a kind of making method of composite fertilizer containing rare-earth elements, belongs to the biological chemistry industrial circle.

At present, mostly the chemical fertilizer that uses on China's agricultural is unit fertilizer, because the composition of unit fertilizer is single, causes easily that therefore plant lacks nutrition, causes the poor growth phenomenon, and there is certain side effect in the soil, for example, makes the hardening soil, sclerosis etc.In order to overcome the deficiency of unit fertilizer, the research of China's agrochemical has begun to turn to multi-component composite fertilizer by unit fertilizer.

The making method that the purpose of this invention is to provide a kind of efficient rare-earth multi-component composite fertilizer.This composite fertilizer containing rare-earth elements except contain plant-growth the nitrogen, phosphorus, potassium of a large amount of needs, also contain element and organism such as the requisite copper of plant-growth, iron, zinc, calcium, magnesium, molybdenum, borax, naphthylacetic acid, red syphilis.In addition, also contain the micro-rare earth nitrate element that can play regulating effect to plant-growth.Therefore can overcome well and use the fertile caused plant in unit to lack nutrition, poor growth phenomenon.Also have the minimizing sprout term disease simultaneously, improve the function of Soil structure.

Making method of the present invention is as follows: with purity is that ammonium phosphate, potassium primary phosphate, monocalcium phosphate, urea and purity more than 90% is ammonium sulfate, zinc sulfate, copper sulfate, manganous sulfate, ferrous sulfate, ammonium molybdate, sal epsom, borax and the rare earth nitrate element mechanically mixing more than 96.5%, adds purity behind the crushing screening again and be that red enzyme more than 96.5% plainly stirs with naphthylacetic acid, seasoning becomes powdered to get final product.

The making embodiment of composite fertilizer containing rare-earth elements: get proportioning and be 10% ammonium phosphate, phosphorus potassium dihydrogen, monocalcium phosphate, urea, borax, with 5% ammonium sulfate, ferrous sulfate, 8% zinc sulfate, ammonium molybdate, 4% copper sulfate, 3% has manganous sulfate, 2% sal epsom, crushing screening after 6% the rare earth nitrate element mechanically mixing, and then adding 4% red enzyme element, the naphthylacetic acid nature that stirs dries into powdered.

Because rare earth element can strengthen microbic activity in the soil, increase soil fertility, the stimulating plant growth, therefore this composite fertilizer containing rare-earth elements can make the root system of plant prosperity, vernalization growth encourage, branches and leaves are sturdy, full seed, or other composite fertilizer fertile with the unit compares, this composite fertilizer containing rare-earth elements obvious effect of increasing production, show that according to the field test results of carrying out in the area, Inner Mongol at present this fertilizer can make the farm crop per mu yield improve 20-30% if be used for clayed ground, if be used for sandy soil ground, can make per mu yield improve 20-70%.Particularly in the plant-growth later stage, spray under the situation that root system of plant is aging, fertilizer sucting ability reduces, effect is more remarkable.In addition, the rare earth essence that adds in this fertilizer is the rare earth nitrate element through nitric acid treatment, thereby can not produce any side effect or harm to people, animal and farm crop.

This fertile using method is versatile and flexible,, also can do root and execute pouring as the seed soaking seed dressing except main; Topdress when using, can fill with, can spray, all can obtain good effect of increasing production.

Claims

1, a kind of making method of composite fertilizer containing rare-earth elements, it is characterized in that crushing screening after rare earth nitrate element and ammonium phosphate, potassium primary phosphate, monocalcium phosphate, urea, ammonium sulfate, zinc sulfate, copper sulfate, manganous sulfate, ferrous sulfate, sal epsom, ammonium molybdate, borax, red enzyme element, the naphthylacetic acid mechanically mixing is dried powdering then naturally.
