Embodiment Construction

[0018] A kind of artificial cultivation method of Chinese cabbage, comprises the following steps:

[0019] (1) Select the excellent plants of A. chinensis with stable genetic properties, good growth and plant height of 0.7-1.0m after introduction and domestication in plastic greenhouses. Cut off the terminal buds, remove the larger leaves on the periphery, wash them with tap water for about 30 minutes, and put them in an ultra- Soak in 75% alcohol solution for 30s on the clean workbench, then soak in 0.1% mercuric chloride solution for about 10 minutes, rinse with sterile water for 5-6 times, dry it with sterile absorbent paper, and peel off the young terminal buds as explants ;

[0020] (2) Select young terminal buds without peeling scars from the aseptic explant materials that have passed through the pollution gate, and inoculate them in an additional 2.0-4.0 mg / L (2.0 mg / L or 3.0 mg / L or 4.0 mg / L) 6-BA and 0.1-0.6mg / L (0.1 mg / L or 0.3 mg / L or 0.6 mg / L) NAA induction medium...

Abstract

Belonging to the technical field of artificial plant cultivation, the invention specifically relates to an artificial cultivation method of gynura divaricata (Linn.) DC. At present, natural conditions limit the promotion and planting of gynura divaricata (Linn.) DC. in northern areas, thus the artificial cultivation method of gynura divaricata (Linn.) DC. is provided to ensure the normal growth of gynura divaricata (Linn.) DC. in northern areas and maintain its quality and advantages. Practice of the invention shows that an effective technical route for tissue culture and rapid propagation of gynura divaricata (Linn.) DC. includes sterile material acquisition, adventitious bud induction, strong bud subculture and proliferation, rooting culture, seedling adaptation, and tube plantlet transplant and cultivation. On the one hand, bud induction and subculture and proliferation are performed by controlling the concentration and proportion of medium and its additional hormones, so that the original plant characteristics are maintained and environmental adaptation of the plant is strengthened. On the other hand, with unique plantation layout and reasonable temperature and humidity control, as well as normative field operation ensuring the quality and output, the method of the invention can reach the effects of short culture time, rapid seedling emergence, little variation, good plant quality and high production efficiency.

Description

technical field [0001] The invention belongs to the technical field of plant artificial cultivation, and in particular relates to an artificial cultivation method of Chinese cabbage. Background technique [0002] Gynura divaricata (Linn.) DC., also known as white-backed notoginseng, is a perennial herb of the family Asteraceae and is mainly distributed in Taiwan to South China and Southwest China. It has dual values ​​of food and medicine. The young shoots and young leaves of Baizicai can be used as vegetables or processed into food, with good taste and rich nutrition. Baizicai contains high content of calcium, potassium, sodium, magnesium, iron and other minerals, among which the content of calcium and iron is several times or even dozens of times that of ordinary green leafy vegetables. Baizicai is also rich in a variety of active ingredients that are beneficial to human health, such as soluble dietary fiber, plant polysaccharides, and flavonoids, which have certain nutri...
