Embodiment 1

[0048] Method for rapid screening of cabbage varieties with low accumulation of Pb:

[0049] Step 1, preparing a device for rapid screening of cabbage seeds with low accumulation of Pb.

[0050] as attached figure 1 As shown, the device includes a light-shielding box 1 equipped with nutrient solution, and a cover 3 fixed on the light-shielding box 1 by a right-angle buckle 4. The four corners of the cover 3 are respectively provided with supports 5, and the cover 3 is provided with 10 Each aperture is the aperture 6 of 1.5cm, and the horizontal interval of aperture is 7cm, and vertical interval is 6cm, and described shading box 1 both sides are provided with buckle 2.

[0051] The shading box 1 and the cover 3 are made of PVC material with a thickness of 3mm, length: 45cm, width: 15cm, height: 10cm.

[0052] Step 2. Prepare a device for rapid screening of cabbage varieties with low Pb accumulation according to the above, and fill the nutrient solution in the light-shielding ...

Abstract

The invention relates to the technical field of agricultural technology and biotechnology cross technologies, and particularly discloses a method for rapidly screening low-accumulation heavy metal crop varieties and a device used by the method. The method comprises the steps that the device for rapidly screening the low-accumulation heavy metal crop varieties is manufactured, then crop seeds are subjected to vernalization, the seeds are cultivated by using a nutrient solution after the seeds are sowed in nutrient agar medium of the device, after crops are cultivated to the required period, a heavy metal solution is added to the nutrient solution, the crops are harvested after cultivation, and low-accumulation heavy metal crop variety screening is carried out. The device is made of light-proof PVC boards, so that harmful substances are not prone to be leached out to affect a research result, and a dark condition like that roots of the crops are in soil can be simulated; a centrifuge tube and small holes are simultaneously used for marking, and thus the marking is convenient; and by adopting a water culture mode for cultivation, the nutrient solution can provide nutrients and water, so that the survival rate is high, and clean and complete crop plants, particular the roots, can be obtained rapidly and accurately.

Description

technical field [0001] The invention relates to the interdisciplinary technical fields of agricultural technology and biotechnology, in particular to a method for rapidly screening low-accumulation heavy metal crop varieties and a device used therefor. Background technique [0002] In recent years, the long-term accumulation of soil pollution problems has begun to emerge and is showing an increasing trend. In some areas, heavy metal pollution hazards in soil occur frequently, which poses a serious threat to the safety of agricultural products and human health, and has attracted great attention from the state and relevant departments. [0003] Regarding the remediation method of heavy metal pollution in soil, at present, the emerging bioremediation method is to use plants and microorganisms to absorb, transport and metabolize heavy metals in the soil to repair heavy metals in soil, including the cultivation of hyperaccumulator plants and low accumulation crops, Compared with ...
