Method for cultivating dendrobium officinale by using back wall of solar greenhouse and cultivation facility

Abstract

The invention discloses a method for cultivating dendrobium officinale by using a back wall of a solar greenhouse and a cultivation facility. The soil back wall of the solar greenhouse is made full use of, sphagnum is adopted as a substrate for dendrobium officinale cultivation, and a mode of covering dendrobium officinale with black sunshade nets and spraying dendrobium officinale in the solar greenhouse is adopted in summer, so that the temperature, the humidity and the illumination in the solar greenhouse can completely meet growth needs of dendrobium officinale. According to the method for cultivating dendrobium officinale by using the back wall of the solar greenhouse and the cultivation facility, not only can the characteristics, namely the suitable temperature and humidity and the weak illumination at the back wall of the solar greenhouse, be made full use of, but also the moisture which is produced in the solar greenhouse and bad for vegetable planting is utilized and consumed, and carbon dioxide released by a main planting vegetable through breath in the darkness at night can be fixed by dendrobium officinale so as to promote the growth of dendrobium officinale; meanwhile, since the back wall, which is usually idle, of the solar greenhouse is made full use of, the capital investment of the cultivation facility of dendrobium officinale is saved, and a batch of a crop is increased in the solar greenhouse, so that a win-win effect of vegetable planting and the dendrobium officinale cultivation is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation methods and cultivation facilities, in particular to a method and cultivation facilities for cultivating dendrobium officinale by utilizing the back wall of a solar greenhouse. Background technique [0002] Dendrobium officinale is a plant of the genus Dendrobium in the family Orchidaceae. It is a traditional precious Chinese medicinal material, and is currently mainly used as a traditional Chinese medicinal material and fresh food. In recent years, as people know more and more about Dendrobium candidum, the demand for Dendrobium candidum is increasing day by day. Wild Dendrobium candidum is suitable for growing in clusters in warm, humid, less sunlight, proper ventilation, well-ventilated root system, and good drainage. It needs to be attached to trees and buds to climb or hang to grow. The existing cultivation methods of Dendrobium candidum, such as imitating wild hanging tree ...

Problems solved by technology

However, the growth of Dendrobium candidum is slow, and the cost of planting Dendrobium candidum in a single facility is high and the cost recovery is slow

[0004] At present, most of the cultivation substrates of Dendrobium candidum are composite substrates mixed with bark, sphagnum moss, vermiculite, stones, etc., which need to be mixed manually, and are only suitable for cultivation in the humid and rainy environment in the south. The climate in the north is dry, so it is necessary to select a Good water retention and suitable substrate for the growth of Dendrobium officinale
