Aeroponic cultivation device for Dendrobium officinale and cultivation method for Dendrobium officinale

Abstract

An aeroponic cultivation device for Dendrobium officinale is characterized in that: a vertical hollow column (1) is used as a cultivation base; atomization nozzles (2) are arranged in the hollow column from up to down; the atomization nozzles are connected to a liquid supplying pool (4) by a pipeline (3); the pipeline (3) is provided with a water pump (5). According to the invention, the atomizing time can be regulated based on the temperature and the humidity, and requirements of plants for water and fertilizer can be satisfied; the cultivation method has the beneficial effects that: a three-dimensional planting technology is adopted, compared with the conventional cultivation method, a lot of land can be saved, and the land utilization rate is improved by greater than 5 times; the planting matrix is not needed, and the investment cost is saved; interplanting can be performed, through adoption of the aeroponic cultivation technology, interplanting can be performed in the forest or the sanmu medical materials, and the economic benefits can be significantly improved by adoption of the sanmu medical materials or other economic forest formed by trees with high economic values such as cinnamomum camphora and osmanthus fragrans; the cultivation method is suitable for the growth of the Dendrobium officinale.

Description

technical field [0001] The invention belongs to a dendrobium candidum cultivation device and a cultivation method thereof. technical background [0002] The existing Dendrobium candidum cultivation technology has transitioned from the original climbing to the cultivation in plastic greenhouses, and this greenhouse cultivation is to cultivate by transplanting seedlings on the prepared substrate. The disadvantage of this cultivation method is that it needs to build a plastic greenhouse, which occupies a large area, takes a long construction process, consumes a lot of materials, and results in high production costs; the use of substrates for cultivation requires a reasonable formula and a fine preparation process, which not only costs High, time-consuming and labor-intensive; and the use of plastic greenhouses due to the isolation of the plastic film of the greenhouse, the sunlight and rain needed by the plants, especially the rain and dew, and the air cannot be directly receiv...

Problems solved by technology

The disadvantage of this cultivation method is that it needs to build a plastic greenhouse, which occupies a large area, takes a long construction process, consumes a lot of materials, and results in high production costs; the use of substrates for cultivation requires a reasonable formula and a fine preparation process, which not only costs High, time-consuming and labor-intensive; and the use of plastic greenhouses due to the isolation of the plastic film of the greenhouse, the sunlight and rain needed by the plants, especially the rain and dew, and the air cannot be directly received, which will affect the growth and quality of Dendrobium candidum

Moreover, the ventilation conditions in the plastic greenhouse are poor, and it is difficult to effectively control diseases and insect pests. The quality of Dendrobium officinale is difficult to guarantee due to the excessive use of pesticides, and the excessive use of chemical fertilizers and pesticides is difficult to guarantee the safety of human life.
