Problems solved by technology

However, through many years of practice, it has also been found that these technologies still have certain deficiencies: the direct seeding method, because the seeds are too small, the viability is low; the cutting method, the germination rate is low, only about 20-40% germinate, and the stem nodes that have bloomed are very The germination is less, and the germination of the sprouts is irregular, and the growth is slow; the division method, the cost is high, the wild seedlings are few, and the wild seedlings are not allowed to be randomly picked due to environmental protection regulations; the tissue culture method, the output is high, but the investment cost is correspondingly large, and the technology The requirements are relatively strict, and it is difficult for ordinary people to grasp, and all seedlings must be hardened, and the survival rate of direct transplantation in field is low

Embodiment 1

[0011] Embodiment one, Select fresh stems of Dendrobium dendrobii that are healthy and free of diseases and insect pests in the same year. When the leaves have not fallen off during October-November, discard all the stem tips except the ones that are naturally sealed. After 25 days, cut them off and put them in the sun to dry. After 10 hours, when the cutting edge turns white and shrinks, it can be taken into the house and spread out to dry. When the dehydration reaches 20-30%, cut it into 4-8 cm long sections, each section has 2-3 knots, and put it in the sun again. When the cutting edge turns white and shrinks, put it into a bamboo blue basket and put it in a high-temperature greenhouse to accelerate germination. Before the beginning of spring, the temperature is controlled at 15-25°C, and the humidity is controlled at 40-60%. After the beginning of spring, the temperature is raised to 25-30°C, and the humidity is 50-70%. Pay attention to observation, and remove the flower b...

Embodiment 2

[0012] Embodiment two, Choose healthy fresh strips of Dendrobium candidum that are healthy and free from diseases and insect pests. From December to January of the next year, before the leaves fall off, except for the natural tipped ones that can be taken directly, all of them are tipped. After 25 days, they are cut and placed in the sun. Dry in the sun for 12 hours, the cuts will turn white and shrink, and you can take them to the house to spread to dry. When the dehydration reaches 20-30%, cut them into 4-8 cm long sections, each section has 2-3 knots, and then dry them in the sun until they are cut. The mouth turns white and shrinks. It can be put into a carton and placed in a high-temperature room to accelerate germination. Before the beginning of spring, the temperature is controlled at 15-25°C, and the humidity is controlled at 40-60%. After the beginning of spring, the temperature is raised to 25-30°C, and the moisture is 50-70%. The flower buds on the seed strips will...

Embodiment 3

[0013] Embodiment three, Select fresh strips of Dendrobium nobile that are healthy and free from diseases and insect pests. Between December and January of the next year, before the leaves fall off, except for those with natural tips that can be used directly, the rest are all tipped, and cut off after 25 days. , and then put it in the sun for 10 hours. When the cutting edge turns white and shrinks, it can be put in the house to spread and dehydrate. When the dehydration reaches 20-30%, it is cut into 4-8 cm long sections, each section is 2-3 sections, Put it in the sun again until the cutting edge turns white and shrinks, that is, put it in a cardboard box and put it in a high-temperature room to accelerate germination. Before the beginning of spring, control the temperature at 15-25°C, moisturize 40-60%, after the beginning of spring, control the temperature at 25-30°C, and adjust the humidity at 50-50%. 70%, strengthen observation, and remove flower buds in time. After the...

Abstract

The invention discloses a greenhouse sprouting breeding method of fresh dendrobe strips and relates to a plant asexual breeding technique. The treated fresh dendrobe strips are selected and placed into a greenhouse, after high-temperature sprouting and low-temperature seedling culture, the sprouting percentage is increased for many times, the sprout can be directly cultivated to a land for growing field crops without domestication, and the sprout grows to 10-80 cm at the same year. The greenhouse sprouting breeding method has the advantages of low cost and easy operation, and is a practical seedling culture method of the dendrobe.

Description

technical field [0001] The invention relates to plant vegetative propagation technology, in particular to a green-house germination-promoting method for fresh dendrobium dendrobium. Background technique [0002] Dendrobium is a perennial herbaceous epiphyte of Orchidaceae. There are more than 80 native species of Dendrobium in my country alone, which are widely distributed in the vast areas from the Qinling Mountains to the south of the Huaihe River. Among them, there are more than 60 native species in Yunnan. Since ancient times, my country's traditional Chinese medicine community has used many varieties of Dendrobium: Dendrobium nobile, Dendrobium officinale, Dendrobium purple, Dendrobium yellow grass, etc. as treasures of traditional Chinese medicine for curing diseases and strengthening the body. Modern medical research has proved that Dendrobium has anti-aging, improving immunity, promoting blood circulation and removing blood stasis, enhancing cardiovascular function, ...
