Problems solved by technology

Among the many methods of raising seedlings, there are different advantages and disadvantages. For example, traditional seedling raising is to use mature tiny seeds commonly known as anthers and mix them in rice soup, and then use a brush to paint them on living trees to let them grow naturally. seedlings, the method is simple, the cost is low, and it is not necessary to harden the seedlings when transplanting, but the emergence is uneven, the survival rate is low, and the operation and management such as watering and fertilization during the seedling cultivation are inconvenient; in addition, the patent No. 201210127795.3 is called "Dendrobium fresh bar greenhouse "Pregermination propagation method" is a better seedling raising method. It is popular because of its high germination rate, fast growth of sprouts, easy operation, and relatively low cost, but there are still some shortcomings: two sets of high and low temperature greenhouses must be built for temperature control, Using mature seed strips as the female parent will undoubtedly increase the investment cost

Embodiment

[0007] Embodiment: finish in six steps

[0008] 1. Select a broad-leaved sparse forest with an altitude of 1300 to 1700m and an annual average temperature of 14 to 28°C as a breeding site, and properly repair it so that the row spacing of the trees in the forest is 4 to 5 meters;

[0009] 2. Build the seedbed: Use two fir columns with a diameter of 10 to 15 cm and a length of 1.3 to 1.5 meters as uprights. One end is buried in the ground, and the other end is unearthed 0.8 to 1 meter. The distance between the two columns is 1.3 meters, and one is 1.5 meters long. A log with a thickness of 13 cm is nailed to the top of the two columns to form a row of bed frames. Between the two rows of bed frames, multiple pieces of fir boards with bark are laid upward and nailed on the log to form a seedbed. The length of each moisture seedbed is determined according to the site conditions, and the distance between each moisture seedbed is 90 cm; 5-point water pipes are arranged around the se...

Abstract

The invention discloses an open forest seedling cultivation method for Den. devonianum Paxt. An open forest land with suitable altitude and temperature is selected, an elevated seedbed is set up, micro nozzles are distributed, the seedbed is paved and covered with a sunshade net, artificially-pollinated dendrobium capsules are collected, the dendrobium capsules are gashed, and seeds are scattered into a nutrient solution formed by blending liquid dung, rice water and clear water and then are sown to the seedbed in a spraying mode. According to the open forest seedling cultivation method, emerged seedlings are orderly and strong, seedling hardening is not needed, the cost is low, management is easy, and the effect is good.

Description

technical field [0001] The invention belongs to the propagation and seedling raising technology of Dendrobium dendrobii of Orchidaceae, in particular to a method of thinning forest seedlings of Dendrobium dendrobii. Background technique [0002] Dendrobium is a perennial herbaceous epiphytic plant, which is a large genus of Orchidaceae. Some species in this genus are often used to cure diseases and strengthen the body, such as Dendrobium candidum, Dendrobium xinchai, and the new star that has gained fame and popularity in recent years- -Purple dendrobium. Among them, Dendrobium dendrobii has another name called dendrobium dendrobium, and Den.davonianum Paxt has the effects of improving human immunity, promoting blood circulation and removing blood stasis, enhancing cardiovascular function, and anti-cancer swelling. Its products are very popular among people. By harvesting wild dendrobium, Far from being able to keep up with the growth of market demand, various methods of ar...
