A kind of dendrobium cultivation method that improves facility utilization

Abstract

The invention discloses a dendrobium cultivation method for improving facility utilization, and relates to the technical field of dendrobium cultivation. The method comprises the following steps: (1) building an elevated cultivation bed in the facility for the production and cultivation of Dendrobium, and the ground under the bed is used as a false planting seedbed to carry out the artificial planting and hardening of Dendrobium tissue culture seedlings; (2) Fermentation treatment of the main raw materials of the cultivation substrate; (3) ) preparation of cultivation medium, filling cultivation bed and seedling tray packing; (4) planting dendrobium seedlings after artificial planting and hardening into elevated cultivation beds for post-planting management; (5) selecting appropriate age dendrobium tissue culture The seedlings are adapted to the indoor hardening, and then they are artificially planted in the seedling trays and placed on the artificial planting bed for post-planting management. The method can not only improve the utilization rate of facilities, but also has a high survival rate of colonization and rapid growth and development; and can provide dendrobium production seedlings with robust growth and high survival rate of colonization for facility cultivation and ecological imitation cultivation while carrying out production cultivation.

Description

technical field [0001] The invention belongs to the technical field of dendrobium cultivation, and in particular relates to a dendrobium cultivation method for improving facility utilization. Background technique [0002] Dendrobium (Dendrobium), also known as Dendrobium orchid, is a perennial epiphytic herbaceous plant of the genus Dendrobium in the family Orchidaceaceae. It is an important medicinal and ornamental plant. , the origin is mainly distributed in tropical and subtropical Asia, Australia and Pacific islands, there are more than 1,500 species in the world, and about 76 species in China, most of which are distributed in Southwest, South China, Taiwan and other places, of which nearly 40 species have medicinal properties value. The types of Dendrobium in my country only account for about 5% of the world, but its medicinal development and utilization are at the forefront of the world. Dendrobium is a traditional Chinese medicinal material with a long history of app...

Problems solved by technology

The seeds of Dendrobium candidum are extremely small, with incomplete embryonic development and lack of endosperm tissue. Under natural conditions, they need to coexist with some fungi (blue bacteria) to germinate, and the germination rate is extremely low. For example, the seed germination rate of Dendrobium candidum is less than 5%.

Its defect is that the first three items all use peat as the main raw material of the matrix, while peat resources in my country are relatively small and are non-renewable natural resources. Although the research of Liu Shihui et al. did not use peat as the main raw material of the matrix, the The nutrients in the plant are very little, and the requirements for fertilization management after artificial planting are high, requiring "thin fertilizer and frequent application". Not only does it need to spray liquid fertilizer multiple times, but also apply granular slow-release fertilizer to help Dendrobium candidum grow vigorously; at the same time, These 4 studies all need special facilities for artificial planting and hardening. Because the adaptability of tissue culture seedlings is poor and the requirements for environmental conditions are high, the requirements for facilities and the level of cultivation management are also high. The facilities for planting and hardening seedlings are relatively simple or the management is extensive, and the survival rate of fake planting of tissue culture seedlings is still relatively low

However, the current method of facility cultivation of Dendrobium in my country generally adopts elevated cultivation beds for cultivation, and the ground and space under the cultivation beds are generally idle and useless, which is a great waste of cultivation facilities
