Seedling growing method for improving stress resistance of Chinese cabbage seedlings

Abstract

The invention discloses a seedling growing method for improving the stress resistance of Chinese cabbage seedlings. The seedling growing method includes pre-treating seeds; preparing bed soil; sowing the seeds; managing seedling beds after the seedlings emerge; preventing and treating plant diseases and insect pests. The seedling growing method has the advantages that moderate water management is matched with water absorption effects of montmorillonite powder and the like in the bed soil, accordingly, the seedlings can keep under low-humidity conditions, transpiration effects can be improved, and calcium and magnesium absorption can be promoted; longitudinal growth of the stems of the seedlings in low-humidity states can be reduced, accordingly, the seedlings are robust, the stress resistance of the Chinese cabbage seedlings can be enhanced, development of the roots of the Chinese cabbage seedlings can be promoted, and the growth performance of the Chinese cabbage seedlings can be improved.

Description

technical field [0001] The invention relates to the technical field of plant seedling raising, in particular to a seedling raising method for improving the stress resistance of cabbage seedlings. 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...

Problems solved by technology

[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
