Abstract

The invention provides a method for improving the ability of tartary buckwheat seedlings to resist heavy metal lead stress, comprising the following steps: selecting tartary buckwheat seeds with no scars on the outside and full grains, drying them in the sun, disinfecting them with disinfectant, and washing them with distilled water; Submerge the washed seeds in the seed soaking solution and soak them at a constant temperature; wipe and disinfect the seed germination box with alcohol, then put it into double-layer filter paper, spread the soaked seeds evenly on the filter paper, and cover the box Cover and place in a shading incubator to obtain tartary buckwheat seedlings; select strong seedlings that grow neatly, plant them in loose and flat soil, cover the roots with soil, and then apply mixed fertilizer to each seedling. The invention cultivates the seedlings by means of disinfection, seed soaking and shading cultivation, and can effectively improve the vitality of the tartary buckwheat seedlings under the lead stress condition, so as to resist the heavy metal lead stress and increase the germination rate of the tartary buckwheat seeds.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a method for improving the ability of tartary buckwheat seedlings to resist heavy metal lead stress. Background technique [0002] Tartary buckwheat has high nutritional value and medicinal value, strong stress resistance, and short growth cycle. Tartary buckwheat is widely used, not only as food, health food and medicine, but also as an important industrial raw material. During the growth of tartary buckwheat, a large amount of rutin will be produced, which is used in the production of health medicine or tea for the prevention and treatment of chronic diseases such as diabetes, hypertension, and obesity, with extremely high added value. Tartary buckwheat is in great demand in today’s market, and resources are scarce. Countries compete to buy from my country. Japan alone needs to import hundreds of thousands of tons every year. my country can only mee...
