Embodiment 1

[0021] 1. Site selection and site preparation: Through the investigation of the soil environment quality of pepper cultivated land in Guizhou Province, the location of this example is a pepper cultivated land in Huali Town, Kaiyang County, Guiyang City, Guizhou Province, with an area of ​​about 800m 2 , the total amount of cadmium in the cultivated land soil is 2.999mg / kg. Compared with the national soil environmental quality standard, the land is heavily polluted. After plowing, raking, and leveling the selected plots, apply ternary compound fertilizers, and then perform ridges according to the height standard of 20cm, with a ridge width of 70cm, and cover the ridges with a black film with a thickness of 0.01mm for later use.

[0022] 2. Seedling cultivation: A seedling shed was built next to a farmer in Huali Town, Kaiyang County, Guiyang City, Guizhou Province, and the seedlings of pepper (low-cadmium pepper varieties screened in the early stage, line pepper type) seedlings...

Abstract

The invention discloses a method for continuously and safely producing peppers using low-cadmium pepper / sedum plumbizincicola strip intercropping. According to the method, low-cadmium peppers and sedum plumbizincicola are planted in a strip intercropping mode at the same compartment face. By the adoption of the method, not only is it ensured that the cadmium content of pepper fruits does not exceed 0.05 mg / kg which is stipulated in the national food cadmium content limit standard (GB2762-2012), but also it is ensured that cadmium-contaminated soil is restored while agricultural work is not terminated, and the continuous and safe production of the peppers is achieved. The method for continuously and safely producing the peppers using the low-cadmium pepper / sedum plumbizincicola strip intercropping has the advantages of being low in investment, low in workload, not high in technical requirement and the like.

Description

technical field [0001] The invention belongs to the fields of agricultural science planting technology and ecological environment, and specifically relates to a new method for realizing continuous and safe production of peppers by intercropping pepper varieties with low cadmium accumulation and hyperaccumulator plants with sedum sedum. Background technique [0002] In recent years, the problem of agricultural cadmium pollution has become a major agricultural ecological environment issue of widespread concern in my country, posing a serious threat to the sustainable development of modern agriculture and social economy, the safety of agricultural ecological environment and the quality of agricultural products. Due to the particularity of my country's agricultural ecological environment, copying foreign technologies and theories cannot effectively solve the major environmental and scientific problems faced by my country's agricultural field, and it is difficult to effectively cu...
