Abstract
The lead reducing and selenium-rich basal fertilizer specially for organic tea tree has selenium reagent in 3-5 wt% added and activated to form organic selenium fertilizer. The organic tea produced via applying the said lead reducing and selenium-rich basal fertilizer has low lead content and raised selenium content. The present invention has convenient operation and low cost.
Description
Technical field
The present invention relates to the special-purpose fertile field of tealeaves.
Background technology
In the present soil of China, in the atmosphere and plant in residual lead amount, reached startling degree.Lead contamination has become one of the most severe current stealthy killer, the grievous injury people's health.In the world,, do not use the high toxicity agricultural chemicals because same problem various countries are just adopting white gasoline, electrophoretic method, a series of measures of ion exchange method or the like reduce the harm of Lead contamination.Because air and soil are subjected to Lead contamination very serious, the Lead contamination situation in the crops such as grain, vegetables, tealeaves is very severe in China.List says that with regard to tealeaves Lead contamination substantially exceeds the GB regulation, and increases year by year, and plumbous amount is more than ten times of GB in many local tealeaves.
We find that selenium can the harmful heavy metal of antagonism when the health-care effect of research selenium, be used on the tealeaves, can reduce the lead content in the tealeaves.The present invention is with the technique of enriched selenium at tip and reduce the technology of Lead contamination, integrates to be applied on the tealeaves, makes tealeaves not only be rich in selenium ammonia albumen, and lead content is lower than 1ppm, can reach the standard of outlet European Union.Domestic a lot of brand tealeaves is also being made great efforts the production organic tea that creates conditions, and what have also produces tea rich in selenium making great efforts test, but organic tea and tea rich in selenium are combined, and has not only fallen the good method of plumbous but also rich selenium cheaply, yet there are no report.
Summary of the invention
The object of the present invention is to provide a kind of organic tea special use to fall plumbous rich seleno fertilizer, thereby produce the organic tea that is rich in the selenium element in the soil that and is subjected to Lead contamination, make every index meet the requirement of organic tea and tea rich in selenium, lead content is less than 1ppm.
Above-mentioned purpose of the present invention is achieved by the following technical solution:
The invention discloses a kind of organic tea special use and fall plumbous rich seleno fertilizer, add the seleno reagent of 3%～5% weight percent during organic base manure, in the composting process, organise and activate, form organic selenium fertilizer in preparation.
Preferably, described base manure is to get by following method preparation:
Farm manure at composting, macerate the seleno reagent that adds 3%～5% weight percent in the process of system, under 28 ℃～32 ℃ temperature through the slaking in 1～2 week, decompose, produce one group of similar performance in the polymerization process but the complex mixture humic acids of the different aromatic hydroxyl hydroxy acid of molecular size, add 3%～7% lime again, behind the thorough mixing.Farm manure can be farm manure commonly used such as human excrement, pig manure, chicken manure, soya-bean cake, methane-generating pit tunning.Described seleno reagent selenium content is 40%～60%, not mercurous, cadmium.Harmful element such as arsenic, lead.
The present invention is a kind of base manure of new variety, be a kind of with farm manure in the process of preparation fertilizer, allocate 3～5% seleno reagents (by soil property decision) into.Organic base manure like this is rich in selenium, the biotransformation in the time of by fermentation, seleno reagent has strengthened activity under the probiotics effect, in being manured into soil after and lead ion be combined into selenium and the stable insoluble compound of plumbous bonded, be difficult for being absorbed by root.So just hinder absorption and the transmission of plant to lead, and after even a small amount of lead ion is absorbed into plant, also can carry on the tube wall and tracheid's wall of channel and be deposited on plant because of selenium and its effect that absorbs simultaneously, reduce plumbous operational throughput, reduce the lead content in the tealeaves to leaf bud.
Beneficial effect of the present invention is:
The present invention has three big advantages:
1. the production that is applicable to organic tea reduces lead content in the tealeaves simultaneously;
2. the production that is applicable to organic tea increases the selenium content in the tealeaves simultaneously;
3. easy to operate, cost is not high.
This special selenium-enriched organic fertilizer, Feng Yuanhou is manured into soil in the tea place, except that increasing general utility functions such as soil fertility, water conservation, guarantor's fertilizer, still the composition of improving the soil, be applicable to the working condition of organic tea, it can also reduce lead ion quantity in the soil, reduces the function of lead content in the tealeaves.
Compare with delead methods such as the electrophoretic method of external employing, ion exchange methods, this method is economic and practical, and cost is low, and soil is played the improving effect that organises, and can not harden, and can not damage soil, produces benign cycle, is applicable to China's actual conditions.
It has a critical function simultaneously, can increase the selenium content in the tealeaves, and selenium transmits in tea tree comparatively fast, participate in photosynthesis, generate selenium ammonia albumen, not only mouthfeel is improved, and be a kind of good benefit selenium product, tealeaves is found oneself greatly elevated in fame and status, economic benefit is very remarkable.
Embodiment
Embodiment 1
Get 500mg selenium powder (pure selenium powder that Shanghai Smeltery produces, purity is 99.99%), add the 10ml concentrated nitric acid, add 1ml perchloric acid again, make the selenium powder dissolving.Add 10ml hydrochloric acid then, in 80 ℃ of water-baths, catch up with nitre, change to faint yellow by reddish-brown again to colourless to solution.Transfer pH=7 then.Constant volume is stand-by to prescribed concentration.Except that selenium powder, used other reagent are analytical pure.
Embodiment 2
After fully pulverizing with the 95kg soya-bean cake, add the 5kg seleno reagent, the temperature bottom fermentation in the fermenting jar about 30 ℃ adds the 5kg lime powder after two weeks again, mix thoroughly the back the special use of 105kg organic tea plumbous rich seleno fertilizer falls.
Embodiment 3
The inventor is in the dragon well green tea plantation, adopt base manure of the present invention, adopt another invention product (the organic tea special use is fallen the rich selenium of lead enemy worm and topdressed) of the inventor again,, the tail gas of motor vehicle emission is isolated and absorption in conjunction with along both sides of highway plantation isolation strip, stop it to descend slowly and lightly and cause soil and blade face to continue Lead contamination to the tea place, with physical control of insects methods such as light traps, do not spray insecticide simultaneously, make in the tealeaves lead content less than 1ppm, selenium is 0.4ppm, produces organic Se-rich tea.
