Problems solved by technology

At present, a relatively common method is to use cadmium hyperaccumulator plants for green restoration. There are only more than 20 species of cadmium hyperaccumulator plants that have been discovered, and these cadmium hyperaccumulator plants generally have low biomass, short individuals, and slow growth. Therefore, while continuing to screen cadmium hyperaccumulator plants, it is necessary to improve the screened cadmium hyperaccumulator plants, so that they can fully play their role in phytoremediation
[0003] Achyranthes is a cadmium hyperaccumulator plant that can be used as a remediation of cadmium-contaminated soil. Due to its small biomass, the remediation efficiency of cadmium-contaminated soil is low, so it is urgent to find ways to improve its ability to remediate soil.
At present, there is still very little information on how to further improve its ability to remediate cadmium-contaminated soil.

[0018] 1.1 Test material

[0019] In September 2013, the farm (farmland ecology type) of Ya'an Campus of Sichuan Agricultural University collected a plant of Coccanthus chinensis and Achyranthes chrysanthemum with mature fruits respectively, collected their seeds, air-dried and preserved. In May 2014, the collected seeds of Achyranthes chinensis and P. chinensis were sown and seedlings were raised, and grafting began when the plant height was about 10 cm. ), Achyranthes chrysanthemum as a rootstock for grafting, and Acanthopanax as a rootstock for grafting. Achyranthes chrysanthemum without grafting (CK): Transplant and plant Achyranthes chrysanthemum seedlings directly, and collect seeds for preservation. The ghost needle grass is not grafted (CK); the seedlings of the ghost needle grass are transplanted and planted directly, and the seeds are collected and preserved. Achyranthes chrysanthemum is used as rootstock for grafting; the seedling...

Abstract

The invention provides a method for improving cadmium pollution repair capability of Galinsoga parviflora offspring by using grafting. The method comprises the following steps: using sticktight as a stock, and using the Galinsoga parviflora as a cion, grafting, and collecting the cion offspring after the grafting. The method is capable of promoting the grafted offspring of the Galinsoga parviflorato absorb and accumulate the cadmium, and improving the repair capability of the Galinsoga parviflora grafted offspring to cadmium-polluted soil.

Description

technical field [0001] The invention belongs to the field of agricultural technology and land restoration technology, and specifically relates to a method for improving the ability of Achyranthes offspring to repair cadmium pollution by using grafting. Background technique [0002] With the development of the economy, industrial pollution, farmland irrigation, agricultural materials and other factors have caused heavy metals to pollute the soil more and more seriously, among which cadmium pollution is particularly prominent. The area of ​​cultivated land polluted by cadmium in my country has reached 1.3×10 4 hm 2 , involving 25 regions in 11 provinces and cities, therefore, it is imminent to control the problem of cadmium-contaminated soil. At present, a relatively common method is to use cadmium hyperaccumulator plants for green restoration. There are only more than 20 species of cadmium hyperaccumulator plants that have been discovered, and these cadmium hyperaccumulator ...
