[0014] Materials and Methods

[0015] plant material:

[0016] Tree tomato seeds were collected from a three-year-old tree tomato fruiting tree (in an area not polluted by heavy metals) in Ya’an Campus of Sichuan Agricultural University in October 2013, and were sown in a sand table in June 2014.

[0017] In July 2014, plants: the aerial parts of Solanum photeinocarpum, Tageteserecta, Galinsoga parviflora, and Bidens pilosa were planted in the farmland of Ya’an Campus, Sichuan Agricultural University (area not polluted by heavy metals). After washing them with deionized water, they were fixed at 110°C for 15 minutes, dried at 80°C to the constant weight, and cut into small sections less than 1cm with scissors, and set aside.

Abstract

The invention provides a method for promoting the growth of cyphomandra betacea and reducing the cadmium content of the overground part of cyphomandra betacea. The method includes the following step that straw of the overground part of solanum americanum covers soil where cyphomandra betacea is planted. The method not only can reduce the cadmium content of the overground part of cyphomandra betacea, but also can promote the growth of the root of cyphomandra betacea seedlings under the cadmium pollution condition.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for promoting the growth of tree tomato and reducing the cadmium content in its aerial part. Background technique [0002] Tree tomato is native to the Andes Mountains in Peru, Chile, Ecuador, Colombia and Bolivia, and is mainly distributed in Guizhou, Yunnan and Tibet in China. The protein content in tree tomato is as high as 20%, and is rich in various mineral elements, and its fruit is rich in pectin. In addition to eating, tree tomato also has certain medicinal functions, which can strengthen the spleen and stomach. [0003] However, since soil cadmium pollution occurs from time to time, how to avoid the impact of cadmium-contaminated soil on tree tomato planting is a research topic worthy of attention. [0004] Although a variety of methods for treating cadmium-contaminated soil have been produced in this field, most of these methods are time-consu...
