Embodiment 1

[0020] (1) Land selection and land preparation: Through the soil environmental quality survey of cultivated land in Yunnan Province, the location of this example was selected as a cultivated land in Qingmen Village, Jinding Town, Lanping County, Nujiang Prefecture, Yunnan Province, with an area of ​​about 600m 2 , The total amount of cadmium in the cultivated land is 2.00 ~ 5.00mgkg -1 , The total amount of lead is 50.00 ~100.00mgkg -1 . After plowing, raking, and leveling the selected plots, compound fertilizer is applied. After the base fertilizer is applied, the ridges are artificially raised, the ridge width is 80 cm, the ridge spacing is 40 cm, and the ridge height is more than 20 cm. Finally, it is covered with black plastic film (1 meter wide) for later use.

[0021] (2) Seedling cultivation: leased 400m of cultivated land from a farmer in Qingmen Village, Jinding Town, Lanping County, Nujiang Prefecture, Yunnan Province 2 , Use field cuttings to cultivate seedlings of Sedu...

Abstract

The invention discloses a method for realizing remediation while production by using low-accumulation zea mays/sedum plumbizincicola intercropping. The method adopts an intercropping planting mode, sothat the method can ensure that the cadmium content of maize kernels planted on cadmium-contaminated soil meets ''National Food Quality and Sanitation Standards'' in China, and the yield of corn is not lower than that before intercropping; the method can realize normal crop planting on the contaminated soil without affecting the income of farmers in the contaminated areas; and the method has theadvantages of low investment, a small workload, and low technical requirements.

Description

Technical field [0001] The invention belongs to the field of soil remediation technology and agricultural scientific planting, and specifically relates to a new method of intercropping grain crops with low accumulation corn and heavy metal hyperaccumulation plant with sedum for realizing production and restoration. Background technique [0002] In recent years, with the continuous development of mining, smelting, refining and electroplating industries, a large amount of cadmium-containing wastewater is discharged into rivers, causing cadmium pollution. When the environment is polluted by cadmium, cadmium can accumulate in organisms and enter the human body through the food chain to cause chronic poisoning. At the same time, cadmium pollution poses a serious threat to the quality of agricultural products, the safety of agricultural ecological environment, modern agriculture and the sustainable development of social economy. Currently, the main method for remediation of cadmium-co...
