Abstract
The invention belongs to Farmland contamination Treatment process fields, and in particular to cadmium method drops in a kind of rice drop cadmium conditioner and rice, and the rice drop cadmium conditioner is made of one or more of mushroom slag, plant ash, peat, conch meal；Base applies 100-150 kilograms of the conditioner per acre in the paddy soil by mild or moderate cadmium pollution, can effectively reduce cadmium content in rice.This method is mainly using agricultural solid residue as drop cadmium conditioner.Using method of the invention, the Cd concentration of brown rice cultivated in the paddy soil by mild or moderate cadmium pollution reduces 20%-55% than control.The present invention has many characteristics, such as that material is easily sought and raw material storage level is big, low in cost, method is simple, environmental-friendly, drop cadmium is obvious, while realizing agricultural solid residue recycling recycling, has taken into account food safety and environmental protection.
Description
Technical field
The present invention relates to Farmland contamination Treatment process fields more particularly to a kind of rice drop cadmium conditioner and rice to drop cadmium side
Method.
Background technique
Rice is the most important cereal crops of China the first generalized grain crop and southern area.China is facing one
A very severe rice cadmium pollution problem, compared to other heavy metals, cadmium in soil is because of its high mobility, high toxicity and more
Easily the features such as being absorbed by plants, make the quality of rice safety problem in China be concentrated mainly on rice cadmium it is exceeded on.It is reported that rice
The exceeding standard rate of heavy metal cadmium reaches 10% or more.China's paddy soil cadmium pollution is mainly mild or moderate cadmium pollution, therefore, by
Cadmium content method in simple, effective, environmental protection the reduction rice of one kind will be found in the paddy soil of slight cadmium pollution to protect China
Barrier grain quality is of great significance safely.
China, which administers large area cadmium pollution method, at present mainly phytoremediation and chemical passivation method, the former is too long the period
And rice field meeting transitory loss production capacity, the latter can generate bigger influence to soil environment.The money of agricultural solid residue
Sourceization, which recycles, becomes research hotspot in recent years, heavy metal-polluted soil reparation include studied in Cadmium Pollution in Soils reparation also compared with
More, charcoal is a typical case, but charcoal is unfavorable for being widely applied there are the features such as at high cost, preparation is difficult.Cause
This, find one or more of raw material easily seek and lay in it is abundant, low in cost, drop the apparent agricultural solid residue of cadmium will be advantageous
In being widely applied improvement cadmium pollution.
Summary of the invention
The purpose of the present invention is to provide a kind of rice bases to apply conditioner and drop cadmium method, by by mild or moderate cadmium pollution
Soil on base Shi Yougu slag and conch meal configure by a certain percentage made of conditioner reach Cd concentration of brown rice and reduce purpose, should
Method has many characteristics, such as that material is easily sought and raw material storage level is big, low in cost, method is simple, environmental-friendly, drop cadmium is obvious, together
When realize agricultural solid residue recycling recycling, taken into account food safety and environmental protection.
In order to solve the above technical problems, the present invention provides a kind of rice drop cadmium conditioner, and the conditioner is by mushroom slag, vegetation
One or more of ash, peat, conch meal composition.
Preferably, the conditioner is made of mushroom slag and conch meal.
Preferably, the conditioner is made of 100-300 part mushroom slag of parts by weight and 700-900 parts of conch meal.
Preferably, the mushroom slag is Pleurotus eryngii mushroom slag.
Preferably, the conch meal is that shell smashes it through powder obtained by 80-100 mesh.
The present invention also provides a kind of rice drop cadmium method, including use rice drop conditioner, the conditioner by mushroom slag,
The method of administration of one or more of plant ash, peat, conch meal composition, the conditioner is Base-appling once, is applied per acre
Dosage is 100-150 kilograms.
Preferably, the conditioner is made of mushroom slag and conch meal.
Preferably, the conditioner is made of 100-300 part mushroom slag of parts by weight and 700-900 parts of conch meal.
Preferably, the mushroom slag is Pleurotus eryngii mushroom slag.
Preferably, the conch meal is that shell smashes it through powder obtained by 80-100 mesh.
The present invention provides a kind of rice base and applies conditioner and drop cadmium method, passes through the base in the soil by mild or moderate cadmium pollution
Conditioner made of Shi Yougu slag and conch meal configure by a certain percentage makees the absorption of Cadmium in Soil by mushroom slag and conch meal
With being finally reached Cd concentration of brown rice reduces purpose, and this method is easily sought with material and raw material storage level is big, low in cost, square
The features such as method is simple, environmental-friendly, drop cadmium is obvious, while agricultural solid residue recycling recycling is realized, take into account food
Product safety and environmental protection.Using method of the invention, the rice cadmium cultivated in the paddy soil by mild or moderate cadmium pollution contains
Amount reduces 20%-55% than control.
Specific embodiment
Below in conjunction with specific embodiment, technical scheme in the embodiment of the invention is clearly and completely described.
Embodiment 1. is by taking the moderate cadmium pollution paddy soil of Huizhou as an example, specific embodiment are as follows:
(1) conditioner stirs evenly spare according to its parts by weight, 200 parts and 800 parts of conch meal proportions of mushroom slag.
In July, (2) 2018, base applied conditioner, and method of administration is that full field is spread fertilizer over the fields, and amount of application is 150kg/ mus.Control is not applied
Conditioner.
As a result as follows:
| Processing | Cd concentration of brown rice (mg/kg) |
| Conditioner | 0.318 |
| Control | 0.402 |
The result shows that conditioner processing Cd concentration of brown rice is 0.318mg/kg, reduced than control 0.402mg/kg
20.90%.
Embodiment 2. is by taking the slight cadmium pollution paddy soil in Huizhou as an example, specific embodiment are as follows:
