Abstract

The invention provides a foliar blocking and controlling agent capable of reducing cadmium contamination of brown rice, and a preparation method and application thereof, belonging to the technical field of foliar sprinkling fertilizer for crops. The preparation method comprises the following steps: adding, on the basis of each liter of water, 200 to 230 g of silicon dioxide, 60 to 80 g of potassium oxide, 8 to 15 g of calcium oxide, 1 to 2 g of selenium, less than 2 g of adding elements and 1 to 2 g of a plant growth regulator into a container equipped with a stirring device; carrying out uniform mixing under stirring; controlling stirring time and speed; and the discharging the obtained mixture and carrying out so as to obtain the foliar blocking and controlling agent capable of reducing cadmium contamination of brown rice. The application of the foliar blocking and controlling agent comprises a first step of diluting the foliar blocking and controlling agent with water and a second step of sprinkling the diluted agent on the leaves of rice in stages. The foliar blocking and controlling agent inhibits migration of cadmium ions, guarantees ideal cadmium reduction effect on brown rice, realizes the dual effects of cadmium blocking and nutrient absorption of plants, enables the yield of paddy rice per mu to increase by 6% or above, is beneficial for prolongation of the life span of human beings and increases the added value of rice; the preparation method is simple and has no strict requirements on essential factors; and the application method is convenient and efficient.

Description

technical field [0001] The invention belongs to the technical field of spraying fertilizers on the foliage of crops, and in particular relates to a foliar inhibitor and control agent for reducing cadmium pollution of brown rice, and also relates to a preparation method and use thereof. Background technique [0002] As known in the industry, cadmium is a heavy metal element that forms inorganic compounds with chemical elements such as oxygen, chlorine, and sulfur, and is distributed in nature. With the rapid development of modern industry, the pollution caused by industrial "three wastes" has become more and more serious, which has brought cadmium pollution to farmland rice. high content) also directly pollutes the soil. According to the results of soil sampling survey conducted in Shaoguan City, Guangdong Province in 2007, the rate of heavy metals exceeding the standard in Shaoguan City was 22.77%, among which cadmium exceeded the standard by 30 times; the average soil cadm...
