Abstract
Compound rare-earth magnetic fertilizer is the new and effective agricultural high-tech product that integrates rare earth application, slowly releasing trace element and magnetic micro-powder.The technical study of rare earth application is one of country's " six or five " tackling of key scientific and technical problems achievement, and 1986 by national-level appraisal.The effect of trace element in process of crop growth is familiar with by people, could fully be absorbed by plant by slow release but have only it is implanted in the long-acting carrier, in order to avoid hyperabsorption works the mischief.Magnetic micro-powder then can promote crop to rare earth and trace elements absorbed, to obtain bigger effect of increasing production.Purpose, economic benefit and obvious social benefit that it can both reach volume increase and make better products any crop.
Description
The present invention is a kind of rare earth application, the long-acting carrier of the slow release of trace elements of energy and new and effective agriculture high-tech product of magnetic micro-powder of integrating.
The forties end, I am mixing monazite in the boccaro, when making it to increase color developing effect, find that the residue of pouring in the soil can make plant-growth vigorous.Confirm that after deliberation the rare earth element that contains in the monazite has physiologically active to plant-growth.The research work of rare earth application is one of country's research of technique achievement during " six or five ", and 1986 by national-level appraisal, and has applied for patent by people such as Guo Baisheng, and application number is 86100264.I was ruined the chance of having lost application because of the research experiment data in 1984.
Along with progress of science and technology, people are to the understanding of the vital role of trace element in process of crop growth and a new boundary science-magnetobiology flourish in recent years, through my the repetition test research over 8 years, finally compound rare-earth fertilizer is studied successfully.Experimental results show that trace element has only slow release to reach best effect for plant fully absorbs.In can the value of avoiding strain content too much or not enough and cause disadvantageous effect to plant growth, this product is finished this slowly-releasing process by long-acting acid rare earth carrier.
Principle according to magnetobiology, the effect of magnetic micro-powder is to form the low-intensity magnetic field of a constant greater than earth magnetism at the plant root, all is that magnetized water promotes its growth and reaches the purpose that increases output, improves quality and prevent deterioration of strains with what guarantee the crop root absorption.Magnetic micro-powder can also promote crop to rare earth and trace elements absorbed utilization, and this can obtain bigger effect of increasing production than single administration rare earth or little fertilizer.
The present invention can be applied to any crop, and stimulation ratio is 20～80%, and application process is easy, method such as can adopt seed dressing, soak seed, spread manuer in holes, spray.The input on every mu of ground is about 2 yuan, and the increment of its input and output ratio is 1: 21～500, is a kind of economical and practical agriculture high-tech product of easily accepting for the peasant.
Production technique of the present invention is divided following four steps:
One, the preparation of agricultural rare-earth
At first preparation contains R for every liter in retort
2O
3Be the re chlorides of 90～120 grams, and be heated to 80 ℃ through fully stirring after adding bicarbonate of ammonia saturated solution precipitate
Treat to continue insulation (＞80 ℃) again after its precipitation fully and stir that can to obtain volume in ten minutes little, the crystallization shape throw out that particle is big.
With siphonage sucking-off mother liquor from jar, can satisfy the requirement of recovery rate with the single-stage washing.Washing times must be determined by the chloride content in the washings, generally washs the ammonium chloride remnants that can remove for 3～4 times in the throw out.
Filtration is for the washings in the scavenger precipitation thing, for following sour molten operation is together prepared.As precipitate quality and meet the requirements, can remove this procedure from, directly the throw out after the washing is pumped into sour fluid bowl to remove redundant moisture.The molten chemical ingredients of acid reacts as follows:
After earlier carbonated rare earth being sized mixing during operation, to add concentration be 50% industrial nitric acid and be heated to＞80 ℃ can obtain agricultural rare-earth solution.Earth solution is put into the standard enamel jar to carry out concentrating under reduced pressure can to obtain molecular formula is R(NO
3)
36H
2The solid crystal rare earth nitrate of O.After pulverize, compound rare-earth magnetic fertilizer work in-process that screening just can obtain the pale powder shape.
Two, the preparation of long-acting carrier
The various metallic compounds that plant growth is required (separately weighing, must not mix) respectively with trivalent rare earth ions (La
+ 3, Ce
+ 3, Pr
+ 3, Nd
+ 3) be complementary and under the situation that organic amine exists, be prepared into the long-acting carrier of various models of the cellular bug hole structure of having of rhombic system with the low-temperature hydrothermal synthesis method.
Have more electric charge in the framework material of this carrier,, nutritive ingredient in the rare-earth magnetic fertilizer can be discharged in the soil solution lentamente go, to satisfy the needs of crop so can carry out reversible cationic exchange and stronger absorption property is arranged.Because of its cation exchange property is a reversible, so can also adsorb heavy metal element harmful in the soil.
Three, the preparation of magnetic micro-powder
With strontium ferrites (SrFe
12O
19) be raw material, after roasting, be ground into 60 microns ultra-fine micropowder plastochondria, and magnetize after screening that (magneticstrength is 8～10Gs).
Four, the preparation of compound rare-earth magnetic fertilizer
According to the model of serial rare-earth magnetic fertilizer, add the agricultural rare-earth for preparing respectively by formula rate, the long-acting carrier and the magnetic micro-powder of respective model promptly become after thorough mixing is even: A
1The calcareous compound rare-earth magnetic fertilizer of type; A
2Type is magniferous: A
3Zinciferous ... A
9The germanic compound rare-earth magnetic fertilizer series product of type gets final product weighing, packing, warehouse-in through being up to the standards at last.
Claims (3)
- The compound rare-earth magnetic fertilizer series product is a kind of new and effective agriculture high-tech product that integrates rare earth application, slowly releasing trace element and magnetic micro-powder.The technical study work of rare earth application is one of country's research of technique achievement during " six or five ", and 1986 by national-level appraisal, and has declared patent (application number 86100264) by people such as Guo Baisheng.The present invention has crop on the basis of physiologically active at abundant affirmation rare-earth elements of lanthanum and cerium, through me for many years behind the experimental study, the technical indicator of agricultural rare-earth is being done improve and is being added that long-acting trace vector and magnetic micro-powder develop.1, feature of the present invention is to add necessary trace element and the magnetic micro-powder of crop in improved agricultural rare-earth.Magnetic can form a low-intensity magnetic field at crop root, and it can make the hydromagneticization of plant absorbing.Magnetized water can promote crop to rare earth and trace elements absorbed utilization, to reduce its amount of application, can reduce agriculture production cost.
- 2, according to desired in the claim 1, in agricultural rare-earth, add trace element, its feature must be in the soil solution slow release of trace elements.So need earlier various trace elements to be implanted respectively in the long-acting carrier, be prepared into the serial work in-process of various models.
- 3, according to desired in the claim 1, in agricultural rare-earth, add magnetic micro-powder, it is characterized in that and can form a low-intensity magnetic field at crop root greater than the terrestrial magnetic field.It can interact with the biological magnetic field of crop and produce magnetic biological effect, to promote the activation of root cells, makes well developed root system and strengthens the purpose that the nutrient absorbing ability is reached volume increase.
