Embodiment 1

[0022] The ratio of raw materials by weight is 0.05mg / L of selenium and 1000mg / L of amino acid micro-fertilizer.

[0023] Its process step is, according to above-mentioned formula ratio, take by weighing sodium selenate, amino acid micro-fertilizer, sodium selenate is dissolved in water and stirred for 5 minutes, then add amino acid micro-fertilizer, continue to stir for 30 minutes, leave standstill for 1 hour, The finished product is obtained, and the pH is kept at about 6.5 and the temperature is kept at about 25°C during the whole production process.

[0024] The method of use is to plant rice in artificially simulated cadmium-contaminated soil (in which the concentration of cadmium is about 50 mg / kg), and spray the foliage once 21 and 14 days before rice harvest.

[0025] Rice without any treatment was used as the control group.

[0026] The contents of heavy metals and selenium in rice grains after harvest are shown in Table 1.

[0027] Table 1 (mg / kg)

[0028]

Embodiment 2

[0030] The ratio of raw materials by weight is 0.5 mg / L of selenium and 800 mg / L of amino acid micro-fertilizer.

[0031] Its process step is, according to above-mentioned formula ratio, take by weighing sodium selenate, amino acid micro-fertilizer, first add water to dissolve sodium selenate in the configuration tank and stir for 8 minutes, then add amino acid micro-fertilizer, continue to stir for 50 minutes, leave standstill for 1 hour, The finished product is obtained, and the pH is kept at about 6.5 and the temperature is kept at about 15°C during the whole production process.

[0032] The method of use is to sow rice in artificially simulated antimony-contaminated soil (the antimony concentration is about 50 mg / kg), and spray the leaves once 30, 20, and 10 days before rice harvest.

[0033] Rice without any treatment was used as the control group.

[0034] The contents of heavy metals and selenium in rice grains after harvest are shown in Table 2.

[0035] Table 2 (mg / ...

Embodiment 3

[0038] The ratio of raw materials by weight is 1mg / L of selenium and 3000mg / L of amino acid micro-fertilizer.

[0039] Its process steps are, according to the above-mentioned formula ratio, take by weighing sodium selenate, amino acid micro-fertilizer, first add water to dissolve sodium selenate in the configuration tank and stir for 20 minutes, then add amino acid micro-fertilizer, continue to stir for 60 minutes, leave standstill for 1 hour, The finished product is obtained, and the pH is kept at about 6.5 and the temperature is kept at about 30°C during the whole production process.

[0040] The method of use is to plant rice in artificially simulated cadmium and antimony compound polluted soil (the concentration of cadmium is about 25 mg / kg, and the concentration of antimony is about 25 mg / kg), and spray the leaves once 15 days before the rice is harvested. Rice without any treatment was used as the control group.

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: [0001] The invention belongs to the field of agricultural technology, and in particular relates to a plant detoxification growth promoter resistant to heavy metals such as cadmium and antimony and a use method thereof. Background technique: [0002] At present, the problem of land pollution caused by industrial and agricultural production is becoming more and more serious, especially the problem of cultivated land pollution has exacerbated the contradiction of more people and less land in our country. It is estimated that more than 10 million tons of grains are polluted by heavy metals nationwide every year, causing direct economic losses of up to 20 billion yuan. It is urgent to carry out restoration and treatment of contaminated soil. Compared with other physical and biological restoration methods, chemical Remediation has the characteristics of quick effect, in-situ implementation, and remarkable remediation effect, and is more suitable for the pollution ...
