Rice breeding method capable of relieving heavy metal cadmium pollution

Abstract

The invention discloses a rice breeding method capable of relieving heavy metal cadmium pollution. According to the rice breeding method, low-cadmium rice is cultivated by using self gene differences of the rice and rice varieties with low cadmium accumulation amount can be effectively bred under the conditions of long soil and water body treatment period and high cost; the content of heavy metal in the rice is reduced and the healthy, environment-friendly and green requirements are met. According to the rice breeding method, the cultivated low-cadmium rice can effectively reduce the intake of the heavy metal of human beings so as to promote the health of human bodies.

Description

technical field [0001] The invention relates to a rice breeding method capable of effectively reducing heavy metal cadmium pollution in rice, and belongs to the field of plant biotechnology. Background technique [0002] Rice is the most important food crop in my country. However, with the rapid development of industry, due to the influence of industrial "three wastes" and agricultural activities, the problem of heavy metal pollution in rice fields in my country is becoming more and more serious. According to data, the area of ​​cultivated land polluted by heavy metals in my country has exceeded 20 million hectares. After rice fields are polluted by heavy metals, heavy metals in the soil are absorbed by rice and accumulate in grains, and enter the human body through food, which not only reduces the edible quality of rice, but also may Produce bone, kidney disease and even cause cancer, a serious threat to the health of Chinese people. [0003] Among the heavy metal pollutio...
