Abstract
A Se fertilizer for producing Se-enriched feed and raw material of food is prepared from Se ore through pulverizing, activating and mixing with N, P and K.
Description
The technical field of the invention is chemical industry and clay fertilizer technology.
At present, both at home and abroad have only the aqueous solution with the chemical Sodium Selenite of solubility to carry out foliage-spray or root is used, also do not have the selenium fertilizer of special use as the method that improves selenium content of crops.The present invention utilizes the selenium ore deposit, handles through physical-chemical, is made into selenium fertilizer, carries out root and executes, and improves the selenium content of farm crop.Through computer retrieval, this technology not also all both at home and abroad at present.
The objective of the invention is directly to utilize the selenium ore deposit to be made into selenium fertilizer, improve the farm crop selenium content, produce Se-enriched feedstuff and selenium-enriched food, reach the purpose that animal and human's body is mended selenium.Selenium is the essential trace element of humans and animals.There are more than 40 countries and regions to lack selenium in the world.The people and animals of counties and cities of China 72% take the photograph the selenium quantity not sufficient, and northeastward, North China and northwest have large areas seriously to lack selenium, the Keshan disease and the Kaschin-Beck disease that cause because of scarce selenium are endangering about 50,000,000 people ' s healths.Taking the photograph the low slightly wide geographic area of selenium amount has several hundred million people also to need appropriate supplement selenium.The invention provides important farm crop and increase the selenium approach, finally reach human body and mend the selenium purpose.
The present invention adopts the selenium ore deposit that contains selenium average 800～1500mg/kg, be ground into the selenium mineral powder that 60 orders sieve, mix with selenium mineral powder with certain density strong aqua, carry out the ammoniacal liquor activation treatment, increase the solubility of selenium, be convenient to the plant absorbing utilization, the ratio of ammoniacal liquor and selenium mineral powder is 1: 100, selenium mineral powder after the ammoniacal liquor activation treatment can directly be used as selenium fertilizer, also can be mixed and made into composite selenic fertilizer with chemical fertilizer such as nitrogen, phosphorus, potassium.Selenium fertilizer or composite selenic fertilizer can be powderies, also can be made into granular; Can make base fertilizer, also can topdress.Close the selenium level according to soil, determine the concentration and the amount of application of selenium in the selenium fertilizer.In the serious soil that lacks, use, can make agricultural thing comparison selenium content in the same old way improve several times to tens times.In containing the general soil of selenium level, also can make farm crop comparison selenium content in the same old way improve 20～500%.
The selenium fertilizer that the present invention produced and foliage-spray or root are irritated and are executed sodium selenite aqueous solution and compare, have cost low, safe in utilization, do not have the local excessive harm that causes.Simultaneously, owing to also contain various trace elements such as molybdenum, vanadium, strontium, copper, zinc in the selenium ore deposit, also be multielement compound micro fertilizer based on selenium, use the back except that increasing selenium, crop growthing development is also had promoter action, have certain effect of increasing production.
For realizing of the present invention applying, should set up that the selenium ore deposit is felled and transported, a cover production system of processing and the fertile preparation of selenium moulding, contain the area of selenium level, the requirement of different soils and Different Crop, the selenium fertilizer of preparation heterogeneity according to difference.
Claims (3)
- Utilize the selenium ore deposit, through pulverize, the ammoniacal liquor activation treatment, be mixed mutually with nutriment in a fertilizer such as nitrogen, phosphorus, potassium again, be made into powdery or granulous selenium fertilizer, increase selenium as farm crop, reach the purpose that indirect human body is mended selenium.The right of asking for protection is as follows:
- 1, utilize the selenium ore deposit to produce the invention right of selenium fertilizer;
- 2, utilize the selenium ore deposit to produce ammoniacal liquor activation treatment in the selenium fertilizer, with the technology right of ownership of the dissolution rate of selenium in the suitable quickening selenium ore deposit.
