Abstract
The invention discloses a heavy-metal-resistant plant growth detoxification accelerant and a method for using the same. The accelerant is characterized by containing low dose of one of selenate or selenite, wherein an amino acid micro element fertilizer is also added, and the accelerant is sprayed onto the leaves for a plurality of times during a period of 7-40 days before crops are harvested. A method for preparing and the method for using are simple and practicable and are convenient to popularize. By the accelerant, the contents of heavy metals of cadmium, antimonium and the like in the crops can be effectively reduced, the crop yield and quality are improved, and the problem that most people in China insufficiently intake selenium can be relieved through a method of reasonably increasing selenium contents in agricultural products, so that the production safety of the agricultural products in heavy metal pollution regions is effectively guaranteed.
Description
Technical field:
The invention belongs to agricultural technology field, be specifically related to a kind of plant detoxifcation growth stimulant and using method thereof that the heavy metals such as cadmium, antimony is had resistance.
Background technology:
Because Study on Soil Pollution Problems industrial, that agriculture production causes is on the rise, the pollution problem of especially ploughing has aggravated the contradiction that China has a large population and a few land at present.It is estimated, the whole nation is subjected to the grain of heavy metal contamination up to more than 1,000 ten thousand tons every year, nearly 20,000,000,000 yuan of the direct economic losses that causes, need reparation and the control of carrying out contaminated soil badly. compare other physics, biological renovation method, chemistry reparation has the characteristics such as but the instant effect original position is implemented, repairing effect is remarkable, more be applicable to the Pollution abatement of agricultural land soil, wherein, using chemical additive to polluted agricultural land is easy handling and method comparatively commonly used.
Aspect the selection of chemical additive, the stable fixing agent that the present heavy metal that is used for soil, settling and solid waste is stablized immobilization research is existing a lot, the natural organic matter class has peat, compost, bone black etc., and the natural mineral class has Wingdale, natural phosphate ore, calcite, kaolin, montmorillonite etc.; The synthetic class has synthetic nano level phosphoric acid molysite, synthetic zeolite, closes aluminide more, aluminium closes montmorillonite, phosphatic rock etc.; The waste class has flyash, blast furnace slag, red mud etc., and the chemical reagent class has calcium hydroxide, Secondary ammonium phosphate, calcium oxide etc.Above-mentioned materials utilizes mainly with the mode that directly adds soil, and life-time service can cause under soil compaction, the soil fertility and incite somebody to action, and finally causes unbalance, the crop failure of soil ecosystem.
Have in recent years report to show that selenium (Se) can suppress to plant (work) thing to the absorption of heavy metal element, an amount of selenium not only has anti-oxidant, function of detoxification in plant materials, can also promote photosynthesis of plant, improves tissue protein content, improves output.In addition, human body appropriate supplement Se can enhancing body immunizing power, its have delay senility, the cancer-resisting function.
Therefore, in agriculture production and heavy-metal composite pollution environmental improvement, development and use take selenium as main component, improve the chemical additive of Plant Tolerance heavy metal ability and Promoting plant growth, Heavy Metals Quantity of Crop in Wastewater not only can be reduced, the problem of the average daily Se intake of a lot of Area Inhabitants of China deficiency can also be alleviated by the mode that increases Selenium in Plants content.
Summary of the invention:
The present invention seeks to overcome the weak point that prior art exists, a kind of have the plant detoxifcation growth stimulant of the heavy metal resistances such as cadmium, antimony and the application process of said preparation are provided.
Plant detoxifcation growth stimulant of the present invention is that it is wherein a kind of to contain selenate or selenite, and adds the aqueous solution of Amino Acid Chelated Mineral Fertilizer.
The content of each component is in the described promotor, selenium 0.01-1mg/L, Amino Acid Chelated Mineral Fertilizer 500-3000mg/L.
The production method of described promotor is, according to above-mentioned formula rate, take by weighing each component, first with selenate or selenite wherein a kind of in preparing tank, be dissolved in water mix after, add again Amino Acid Chelated Mineral Fertilizer, continue to stir, leave standstill, get product, keep pH in the 6-7 scope in the whole production process, temperature remains on 10-35 ℃ of scope.
Described selenate or selenite wherein a kind of in preparing tank churning time be 5-20 minute, add that to continue churning time behind the Amino Acid Chelated Mineral Fertilizer be 30-60 minute, time of repose is 1 hour.
In calcium, magnesium, phosphorus, potassium, five kinds of elements of silicon one or more have been added in the described Amino Acid Chelated Mineral Fertilizer.
The present invention provides a kind of using method of above-mentioned plant detoxifcation growth stimulant simultaneously, before crop harvesting during 7 to 40 days in, be sprayed onto plant leaf 1-3 time in the foliage-spray mode.
Advantage of the present invention and positively effect:
Plant detoxifcation growth stimulant of the present invention can improve plant to the resistance of various heavy (cadmium, antimony etc.), the energy Promoting plant growth, increase crop yield, improve selenium content in the crop, for the guarantee of the grain-production safety in heavy metal contamination area provides technical guarantee.Its concrete function is as follows:
1, suppresses plant to the absorption of heavy metal
Selenium can alleviate the toxic action of heavy metal on plants, reduces plant to their absorption.Its mechanism comprises the oxidative stress that (1) alleviation heavy metal causes; (2) plant cell structures and the function under the remediating heavy metal stress conditions; (3) the plant photosynthesis under the recovery heavy metal stress condition; (4) reverse the heavy metal stress condition to the impact of plant essential nutrient element; (5) suppress plant to the absorption of heavy metal.
2, improve Selenium in Plants content
The Se of low dosage can not only lessening oxidative stress in the plant materials, can also strengthen the photosynthesis of crop, improves tissue protein content, improves output, strengthens anti-adversity ability.Plant can absorb selenium as main take Se4+, Se6+ and three kinds of forms of organic Se, and the plant detoxifcation growth stimulant of foliage-spray this patent invention can be made selenium content in the object by Effective Raise.Can also effectively alleviate the problem of China's most of population selenium intake deficiency by the mode of suitable raising selenium content of crops.
3, improve the heavy-metal contaminated soil fertility
Amino acid contained little fertilizer not only can improve nutrition content in the soil in this patent invention plant detoxifcation growth stimulant, can also effectively regulate soil ecosystem under life-time service, improves soil microbial activities, increases soil fertility.
