Seedling growing method capable of increasing selenium content of cabbage

Abstract

The invention discloses a seedling growing method capable of increasing selenium content of cabbage. The seedling growing method includes pretreatment of seeds, preparation of seedbed soil, seed sowing, seedling bed management after emergence, and pest control and prevention. According to the seedling growing method for production of selenium-rich cabbage, various selenium-rich raw materials are supplemented as nutrition at the stage of seedlings, high selenium absorption capacity of the seedlings is achieved under cooperation of organic way, inorganic way and microorganism way, growing performance of the seedlings is improved, stress resistance thereof is also improved by increasing in-vivo activity of peroxidase, and further yield of selenium-rich cabbage is increased.

Description

technical field [0001] The invention relates to the technical field of plant seedling raising, in particular to a seedling raising method for increasing the selenium content of cabbage. Background technique [0002] Chinese cabbage is a biennial herbaceous plant among the leafy vegetables of the genus Brassica in the family Brassica. It is eaten with tender leaf balls, rosette leaves or flower stems. Its cultivation area and consumption rank first among all kinds of vegetables in China, and its seedling cultivation Cultivation technology is one of the important factors affecting the yield and quality of Chinese cabbage. [0003] Although people have researched and summarized a relatively complete technical system in the cultivation of cabbage seedlings, due to the influence of factors such as temperature, moisture, seed germination rate, and germination potential, the uniformity of seedling growth cannot be guaranteed, resulting in uneven plant size during planting. First, ...

[0003] Although people have researched and summarized a relatively complete technical system in the cultivation of cabbage seedlings, due to the influence of factors such as temperature, moisture, seed germination rate, and germination potential, the uniformity of seedling growth cannot be guaranteed, resulting in uneven plant size during planting. First, the quality of seedlings is also uneven. At the same time, insufficient or unbalanced nutrient supply will lead to weak seedlings, which will eventually affect subsequent plant growth, yield and quality
