Method for domesticating hardening seedlings of tissue culture seedlings of Nandina domestica firepower

Abstract

The invention relates to a method for domesticating hardening seedlings of tissue culture seedlings of Nandina domestica firepower. The method is characterized by comprising the following steps of establishing a hardening seedling greenhouse; screening and treating a hardening seedling matrix; managing the tissue culture seedlings before the tissue culture seedlings are bottled out; treating the tissue culture seedlings after the tissue culture seedlings are bottled out; transplanting the hardening seedlings of the tissue culture seedlings; managing the tissue culture seedlings after the hardening seedlings of the tissue culture seedlings are planted; and domesticating the hardening seedlings of the tissue culture seedlings for four months to obtain qualified domestication seedlings of the Nandina domestica firepower. By means of the method for domesticating the hardening seedlings of the tissue culture seedlings of the Nandina domestica firepower, surviving rates of the domestication seedlings are increased form 58% of traditional surviving rates to 83.5% so that the surviving rates of the domestication seedlings of the tissue culture seedlings of the Nandina domestica firepower are greatly increased, the tissue culture seedlings which are obtained by four month domestication of the domestication seedlings can basically adapt to growth environment of the greenhouse, root systems of plants are thick, new twigs are good, stalks are thick, and the surviving rates of the transplanted domestication seedlings can reach 95.8%.

Description

technical field [0001] The invention relates to a method for cultivating and domesticating tissue culture seedlings, in particular to a method for cultivating and domesticating tissue culture seedlings of flame nandina, belonging to the technical field of biological cultivation. Background technique [0002] Flaming Nandina belongs to the genus Nandina of the family Nandinaceae. The plant is short and compact, with oval or ovate leaves and extremely short internodes, only 1 / 10 of ordinary nandina. Flame nandina begins to germinate in mid-April in Shanghai area, and grows tender red new leaves. Big, when the temperature rises, it will gradually turn green above 30°C. In December, when the temperature drops below 5°C and the temperature difference between day and night is above 10°C, the leaves begin to turn red. Because it is cold-resistant and evergreen, it will not wither through winter and is very beautiful. , suitable for ground cover and small garden environment layout....

AI Technical Summary

Problems solved by technology

At present, the tissue culture technology of flame nandina has become mature, but the artificial large-scale planting of flame nandina is still in its infancy in my country, and the development speed is relatively lagging behind. The 1-2 months after the seedlings are out of the bottle, the main reason is that the environment of the tissue culture room and the growth environment of transplanting are quite different, which seriously affects the industrialization of flame nandina.

At present, almost no scientific research institutes and enterprises have carried out relevant research on the domestication technology of flame nandina
