Embodiment 1
[0021] A seed initiator of non-heading Chinese cabbage, comprising: ascorbic acid, calcium chloride, gibberellin, polyethylene glycol, buffer and bactericide.
[0022] Wherein, the concentration of the ascorbic acid is 20 mg / L, the buffer is glucose, and the bactericide is tetramethylthiuram disulfide.
[0023] The application method of the non-heading Chinese cabbage seed initiator is to select plump and uniform seeds, place them in 150ml Erlenmeyer flasks, put 500 seeds in each Erlenmeyer flask, and initiate the treatment for 24 hours at 20°C in the dark.
Embodiment 2
[0025] A seed initiator of non-heading Chinese cabbage, comprising: ascorbic acid, calcium chloride, gibberellin, polyethylene glycol, buffer and bactericide.
[0026] Wherein, the concentration of the ascorbic acid is 50 mg / L, the buffer is fumaric acid, and the bactericide is tetramethylthiuram disulfide.
[0027] The application method of the non-heading Chinese cabbage seed initiator is to select plump and uniform seeds, place them in 150ml Erlenmeyer flasks, put 500 seeds in each Erlenmeyer flask, and initiate the treatment for 24 hours at 20°C in the dark.
Embodiment 3
[0029] A seed initiator of non-heading Chinese cabbage, comprising: ascorbic acid, calcium chloride, gibberellin, polyethylene glycol, buffer and bactericide.
[0030] Wherein, the concentration of the ascorbic acid is 80 mg / L, the buffer is glucose, and the bactericide is tetramethylthiuram disulfide.
[0031] The application method of the non-heading Chinese cabbage seed initiator is to select plump and uniform seeds, place them in 150ml Erlenmeyer flasks, put 500 seeds in each Erlenmeyer flask, and initiate the treatment for 24 hours at 20°C in the dark.

Abstract
The invention relates to the technical field of seed initiation, in particular to a no-heading Chinese cabbage seed initiator, which is prepared from ascorbic acid, calcium chloride, gibberellin, polyethylene glycol, buffer agents and sterilization agents, wherein the concentration of the ascorbic acid is 20 to 200mg / L; the two optimum concentrations of the ascorbic acid in the no-heading Chinesecabbage seed initiator are respectively 50 and 80 mg / L; the buffer agents are one or several kinds of materials of glucose and fumaric acid; the sterilization agents are tetra methylthiuram disulfide.The invention also discloses an application method of the no-heading Chinese cabbage seed initiator. Through the seepage initiation effect of the ascorbic acid, the seed cell water absorption is controlled; the seed gemmation power is favorably improved; the gemmation of the no-heading Chinese cabbage seeds is promoted; the functions of preventing membrane lipid peroxidation, clearing away free radicals and maintaining cytomembrane integrality are realized; the young seedling growth is more facilitated.
Description
technical field [0001] The invention relates to the technical field of seed priming, in particular to a non-heading Chinese cabbage seed priming agent and an application method thereof. Background technique [0002] Seed priming is a pre-sowing seed treatment technology that makes seeds slowly absorb water under controlled conditions, thereby preparing physiologically for germination in advance, and is an effective way to improve seed vigor. Seed priming technology has been successfully applied to vegetable crops, agricultural crops, economic crops, ornamental plants, forest trees and other plant species, including such as eggplant, pepper, tomato, cucumber, muskmelon, melon, watermelon, cabbage, carrot, Various vegetables such as celery, spinach, scallions, and onions; various food crops such as barley, wheat, corn, rice, and sorghum; and various ornamental plants such as eucalyptus, verbena, petunia, and pansy. A good germination effect was obtained through the priming tr...
