The patent of invention that patent application number is 200910144692.6 discloses a kind of nano-carbon rare-earth fertilizer, by nano-sized carbon
Rare earth is made with various fertilizer, although also improving the utilization rate of fertilizer, not to the volume increase situation of grain and oil crop or vegetables
It is ideal.
Summary of the invention
Of the existing technology in order to solve the problems, such as, the present invention provides a kind of environment-protection nano carbon rare earth fertilizer and its preparations
Method further improves the utilization rate of fertilizer, increases production crop, vegetables and fresh flower etc. further.
The object of the present invention is to provide a kind of environment-protection nano carbon rare earth fertilizers.
It is a further object of the present invention to provide the preparation methods of above-mentioned environment-protection nano carbon rare earth fertilizer.
The environment-protection nano carbon rare earth fertilizer of specific embodiment according to the present invention, the environment-protection nano carbon rare earth fertilizer by
The preparation of following raw material, the raw material include urease inhibitor, nano-sized carbon, rare earth, nano-silicon, white vitriol and a variety of fertilizer,
The urease inhibitor, nano-sized carbon and rare earth and fertilizer are at cocrystallization complex or mixture.
The research of urease inhibitor starts from the eighties, and China is a large amount of to introduce Technology for Urea Production, and the output of urea more occupies
First of nitrogenous fertilizer.Urea fertilizer has many good qualities, and nitrogen content is high, reaches 46%；Shelf-stable, if without water environment, forever
Can exist with amidonitrogen.Amidonitrogen crop is that benefit has more than is needed, and after only decomposing by soil urease, becomes ammoniacal nitrogen,
Crop can just be absorbed and utilized.However, urea can all digest ammonification in 15 days under conditions of Temperature and water content in soil is suitable for
State nitrogen, crop have little time to be absorbed and utilized, and can volatilize or lose in vain into subsurface flow.Fertilizer is caused to waste, soil and water
System's pollution, soil eutrophication, nitrate nitrogen is superfluous, causes the blowout disease incidence of cancer.So the eighties begins one's study, urase presses down
Preparation.1,4-benzoquinone is the urease inhibitor voluntarily screened, reaches 67% or more to the inhibiting rate of urease activity, be Environmental security without
The free of contamination oxidant of poison, is the patented product of Chinese independent intellectual property right.1,4-benzoquinone, which is added in urea, can inhibit urea
Enzymolysis speed, so that the fertilizer efficiency period of urea is extended to 90~120 days, there is apparent weight-reducing and environmental-protection function.
Nano-sized carbon synergy starts from 2007 in agriculturally application, is that China and the world are applied for the first time in fertilizer upper, belongs to
The creation that Chinese independent intellectual property right and nano-carbon material are applied in fertilizer field.Small-size effect, the large surface of nano-sized carbon
Effect and tunnel-effect show the exceptional function applied in fertilizer.The small-size effect of nano-sized carbon holds itself out to be ammonia and stablizes
Agent can inhibit ammonia volatilization 82%；The large surface effect of nano-sized carbon holds itself out to be soil-solidified-agent, can save fertilizer 30%~50%；
The tunnel-effect of nano-sized carbon can increase conductivity, and being added in fertilizer by measurement nano-sized carbon can increase 37% or more conductivity.From
And nano-sized carbon fertilizer has purification soil, the good ecological functions of environment purification, the heavy metals member such as mercury cadmium lead of energy purification soil
Element.
