Aeroponic method of dendrobium officinale

Abstract

The invention relates to an aeroponic method of dendrobium officinale. The method comprises the steps of: constructing a three-dimensional cultivating frame in a steel structure; disinfecting before planting and cultivating after planting; selecting dendrobium officinale seedlings in advantageous growth after seedling hardening and wrapping the roots of the seedlings by with sponge strip attachments and planting in planting holes; spraying a nutrient solution or water in form of aerial fog to the attachments by a spraying device until the roots penetrate through the attachments and extend into the cultivating frame; and then, spraying the nutrient solution or water to the roots to cultivate by the spraying device and till collecting by the spraying device. According to the invention, growth elements such as temperature, light, water, gas and fertilizer are regulated manually to the optimal state, so that the root system is in a moist state and obtains sufficient oxygen, therefore, the growth period of dendrobium officinale is shortened. The nutrient solution is directly sprayed to the roots of dendrobium officinale by the spraying device to accelerate absorption and utilization of for nutritional elements, so that dendrobium officinale grows more robust and thicker, polysaccharide content is beneficially accumulated. Therefore, the yield and the quality of dendrobium officinale are improved.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to an aerosol cultivation method of Dendrobium officinale. Background technique [0002] Dendrobium officinale Kimura et Migo is a traditional precious Chinese medicinal material, which has the functions of nourishing yin and clearing heat, promoting body fluid and benefiting the stomach, nourishing the lungs and relieving cough, and nourishing the five internal organs. It has obvious effects in improving symptoms of diabetes and atrophic gastritis. Dendrobium officinale grows on semi-shady rocks in mountains at an altitude of 1,600 meters. It likes warm and humid climates and semi-shady and semi-yang environments, and is not cold-resistant. Dendrobium candidum has unique medicinal value, and its stems are used as medicine. In recent years, due to the destructive excavation of medicinal farmers in production areas, wild Dendrobium officinale resources are on ...

Problems solved by technology

[0003] In recent years, some scientific research institutions and enterprises in my country have continuously explored and tested the tissue culture and artificial planting technology of Dendrobium candidum, and have made certain breakthroughs in seedling cultivation and facility substrate cultivation. At present, the artificial cultivation methods of Dendrobium candidum are all adopted Planting in a protected area usually involves laying a substrate on the ground in the greenhouse to make a border, and then planting in the ground, or using a seedbed in a greenhouse to cultivate in an empty container. The above-mentioned cultivation method has the following disadvantages: it is easy to cause pests, especially underground pests and soft organisms such as snails. Animals are seriously endangered. Once pests occur, chemical agents cannot be used to completely eradicate them, which will affect the yield and cause pesticide residues in Dendrobium officinale. In addition, direct planting will easily cause poor drainage, resulting in rotten roots of Dendrobium officinale and disease. In the container cultivation method, the volume of the container limits the growth of Dendrobium candidum, resulting in relatively low input and output. Under the existing cultivation methods, the quality and food safety of artificially cultivated Dendrobium candidum cannot be guaranteed, and the production efficiency is low, which restricts the development of the entire industry.
