Embodiment 1

[0036] A seed treatment method for accelerating the germination of Sedum sedum seeds, wherein: comprising the following process steps:

[0037] (1) Seed selection

[0038] Sorting the Sedum sedum seeds preserved at room temperature, removing impurities, immature seeds and damaged seeds in the Sedum sedum seeds, and then putting the Sedum sedum seeds selected into the container;

[0039] When selecting seeds, put the Sedum sedum seeds preserved at room temperature into water according to the weight of Sedum sedum seeds and the volume ratio of water in a ratio of 1g:2mL, stir them evenly with a glass rod and let stand to remove impurities floating on the water surface, Immature seeds and seeds suspended in water, after that, take out the sedum seeds settled at the bottom of the container, drain and put in the container.

[0040] (2), germination at low temperature and variable magnetic field

[0041] Put the container containing Sedum sedum seeds in step (1) into a magnetic fi...

Abstract

The invention relates to a seed treatment method for accelerating sedum alfredii hance seed germination, which comprises the steps of seed selection, low-temperature variable magnetic field germination acceleration, high-temperature hormone germination acceleration, normal-temperature strong magnetic field germination acceleration, cleaning and disinfection, and sowing. Seed selection, low-temperature variable magnetic field germination acceleration, high-temperature hormone germination acceleration, normal-temperature strong magnetic field germination acceleration, cleaning and disinfection are sequentially carried out on sedum alfredii hance seeds stored at normal temperature, then seedling raising or planting is carried out, the germination rate of the sedum alfredii hance treated through the method can reach about 90% 28 days after sowing, the germination rate of the sedum alfredii hance can reach about 95% 35 days after sowing. The dormancy time of the sedum alfredii hance seeds stored at normal temperature can be effectively and greatly shortened, the germination rate is greatly increased, the seedling rate of the sedum alfredii hance seeds can be effectively increased, and the production period of the sedum alfredii hance can be remarkably shortened, so that the breeding cost of the sedum alfredii hance is reduced, the breeding efficiency of the sedum alfredii hance is improved, and the increasingly serious remediation requirements of heavy metal contaminated soil in China are met.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a seed treatment method for accelerating the germination of Sedum sedum seeds when breeding and planting Sedum sedum seeds. Background technique [0002] Soil is a precious resource for human beings to survive, and a survival resource for human beings to continue and recuperate. In recent years, with the development of human industry, especially the excessive and disorderly mining of mines, coupled with the lack of sufficient protection awareness of soil environmental resources, soil pollution has become increasingly serious, especially heavy metal pollution. According to statistics, the area of ​​arable land polluted by heavy metals such as arsenic, cadmium, lead, and chromium in my country accounts for about 1 / 5 of the total arable land area. Due to heavy metal pollution, my country's annual food production is reduced by more than 10 million tons due to heavy metal p...
