Problems solved by technology

Studies have shown that the deep-rooted Cd / Zn enrichment plant willow (Salix) and the dwarf hyperaccumulator Arabidopsis (Arabidopsis halleri) interbreeding did not increase the plant's extraction efficiency of Cd and Zn

Embodiment 1

[0015] Seeds of mixed plants for testing were collected from the farmland around Chengdu Campus of Sichuan Agricultural University (East longitude: 103°50′, North latitude: 30°42′). Bidenspilosa L.), Bidensparviflora Willd., and Bidens birnata Merr. et Scherff; the grapes used for testing were cutting seedlings of Kyoho, which were purchased from the seedling base of Longquanyi District, Chengdu City, Sichuan Province. The soil for testing was taken from the surrounding farmland of Chengdu Campus of Sichuan Agricultural University, and its basic physical and chemical characteristics are: pH 7.09, total nitrogen 1.50g kg -1 , total phosphorus 0.76g·kg -1 , total potassium 18.02g·kg -1 , total cadmium 1.96mg·kg -1 , Alkaline hydrolyzed nitrogen 94.82mg·kg -1 , available phosphorus 6.30mg·kg -1 , available potassium 149.59mg·kg -1 , and the background effective cadmium content in the tested soil was not detected. The basic physical and chemical properties of the soil and th...

Abstract

The invention belongs to the technical field of agricultural planting, and provides a planting method for utilizing mixed planting to achieve the stable yield of grapes and remarkably lower cadmium content of the grapes. The planting method is to conduct mixed planting on the grapes and bidens pilosa. In the planting method for utilizing mixed planting to achieve the stable yield of the grapes and remarkably lower the cadmium content of the grapes, mixed planting is conducted on the grapes and bidens pilosa, and the planting method has the advantages that the cadmium accumulation in the grapes is remarkably lowered, and the effect on the biomass of the grapes is small.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a planting method for stably yielding grapes and significantly reducing the cadmium content by using mixed species. Background technique [0002] In recent years, due to the discharge of my country's industrial "three wastes" and the excessive application of chemical substances such as fertilizers and pesticides, a large amount of heavy metals have entered the orchard soil system, making the orchard soil heavy metal pollution increasingly serious. Among them, cadmium has become a very toxic heavy metal element because it cannot be degraded in the body. Grapes are rich in nutrients, beautiful in appearance and diverse in product forms, and are one of the important fruits in my country. At present, my country's vineyards are already facing the hazards of heavy metal cadmium pollution. Studies have shown that the Cd content in the vineyard soil in some ar...
