Abstract
The invention uses the fly ash of the thermal power plant as the carrier, and adds nitrogen, phosphorus, potassium and many microelements to mix and stir and make and carry on the magnetization treatment by the permanent magnet to get a brand-new permanent magnet fertilizer, we produce various special compound fertilizers according to the soil condition of northeast area and the demand of various crops in different proportions, it has higher fertilizer efficiency and duration than the ordinary fertilizer time, it also has the characteristic of improving the soil, economic and reliable, it can get higher economic benefits, social benefits and environmental benefits to promote this fertilizer.
Description
The present invention relates to a kind of permanent magnetic composite fertilizer and production method thereof.
Chinese patent CN-90106590,92115074,93102352 and 94104937 disclose fertile prescription and the production method of multiple magnetization, mostly adopt the flyash and the nitrogen of power plant, phosphorus, potash fertilizer mixes, after handling, magnetization uses as a kind of composite fertilizer, but because the composition of the trace element that contains in the flyash of various places power plant is different, the more important thing is, various places edaphic condition differs widely, and various crops are also inequality to the demand of nutrition, and northeast is as China main food producing region, its edaphic condition is arranged, the prescription of above-mentioned patent disclosure or be not suitable for the soil and the crop in northeast, otherwise ratio range is too big, is difficult to match.
The objective of the invention is to overcome the deficiencies in the prior art and a kind of soil of suitable northeast and permanent magnetic composite fertilizer and the production method thereof of crop are provided.

(3) carrier I being mixed back adding binding agent 0-10 with material II and make particle, is 50-120 degree hot-air seasoning with temperature;
(4) granule materials after will drying magnetizes 2-10 and obtains permanent magnetic composite fertilizer after second under high-intensity magnetic field;
The application's permanent magnetic composite fertilizer is deposited following effect;
(1) the crop yield effect is obvious, and as paddy rice, food crop such as wheat can be increased production 10-35%, and vegetables can be increased production 20-50%, and fruit tree can be increased production 10-40%;
(2) improve the soil, the long-term application permanent magnetic composite fertilizer helps the formation of emblem grain unity structure in the soil, and played the physical behavior of improving the soil, increase its ventilation property and water retention capacity, thereby can avoid and reduce for a long time with detrimentally affects such as the soil instinctization that chemical fertilizer caused harden;
(3) the magnetics effect of permanent magnetic composite fertilizer has improved the utilization ratio of nutrient greatly, can make originally and can not after the magnetics effect, can be absorbed by the nutrient that crop absorbs by crop, so permanent magnetism composite fertilizer has effect of increasing production with comparing with the not magnetized composite fertilizer of nutrient, and the magnetics effect was 2 years.
