Problems solved by technology

However, it is costly to maintain the seedling temperature in the alpine region. Once the seedlings are transplanted out of the greenhouse for planting, the cold resistance will be weak due to the influence of the outside temperature difference, and the plant mortality will be high.

Embodiment 1

[0033] The steps of raising cold-resistant cabbage seedlings under low temperature stress are as follows:

[0034] 1. Seed selection

[0035] Choose cabbage seeds with good quality, high yield and disease resistance.

[0036] 2. Seedling tray selection

[0037] Select the seedling raising tray as 100 holes, 54 × 28cm floppy disk, the diameter of the upper opening of each hole is 3.8cm, the lower bottom is 2.0cm, and the seedling raising tray is 4.6cm deep.

[0038] 3. Disinfect the seedling tray

[0039] The used trays may be infected with residual pathogenic bacteria and insect eggs, so the seedling trays need to be cleaned and disinfected. The method is to remove the residual matrix in the seedling tray first, rinse it with clean water, dry it, and soak it in 500 times of carbendazim for 12 hours or soak it in 1000 times of potassium permanganate for 30 minutes to disinfect it. Formaldehyde solution and bleaching powder solution can also be used. Disinfect; disinfected t...

Abstract

The invention discloses a Chinese cabbage cold-resistant seedling growing method under low temperature stress, and belongs to the technical field of plant seedling growing. Cold-resistant management is carried out on Chinese cabbages by adoption of a method of combing phytohormone abscisic acid and leaf surface fertilizer supplementation according to air temperature characteristics of an arctic-alpine region, the phytohormone abscisic acid is sprayed to leaf surfaces once a day after seedlings grow to the 2-leaf stage, fertilizer is supplemented to the leaf surfaces once a day, spraying water to the leaf surfaces every two or three days, and the water content of the seedbed soil is kept to be 70-75%. The seedling growing method comprises the following steps of seed selection, seedling growing tray selection, seedling growing tray disinfection, seed disinfection, constant temperature germination acceleration, seedling growing matrix blending, matrix filling, seedling growing sowing, cold-resistant management and outplanting. According to the seedling growing method, frigid weather resistance of Chinese cabbage seedlings is improved, growth inhibition of seedling rhizomes and leaves is effectively prevented, and a certain pest control effect is achieved.

Description

technical field [0001] The invention relates to the technical field of plant seedling cultivation, in particular to a method for cold-resistant cabbage seedling cultivation under low temperature stress. Background technique [0002] Cabbage, a biennial herb, 40-60 cm high, usually glabrous throughout the plant, sometimes with a few bristles on the midrib of the lower leaves, belonging to Brassicaceae Brassica vegetables. Native to northern China, it was introduced to the south. It is eaten with tender leaf balls, rosette leaves or flower stems. It can be fried, made into soup, and pickled. Together with Chinese cabbage, it has become an indispensable vegetable on the table of Chinese residents. In winter in northern my country, Chinese cabbage is a frequent visitor on the table, so there is a saying that "winter cabbage is as beautiful as bamboo shoots". Chinese cabbage has high nutritional value, so there is a saying that "a hundred vegetables are not as good as cabbage". ...
