Sunlight greenhouse for dendrobium candidum cultivation and cultivating method of dendrobium candidum

Abstract

The invention provides a sunlight greenhouse for dendrobium candidum cultivation and a cultivating method of dendrobium candidum. The sunlight greenhouse is arranged in the manner that the indoor ground is lower than the outdoor ground, walls are arranged on the east, the west and the north, a lighting plane is arranged on the south; and the orientation of the lighting plane is south by east 10-20 degrees, and the lighting plane is divided into a light-transmitting area and a lighttight area distributed at an interval. The cultivating method of dendrobium candidum includes the steps that (1), controlling the illumination intensity within 3000-10000lux; (2), controlling the temperature within 5-32 DEG C; (3),controlling the humidity within 60-80%; (4), controlling the PH value of water within 5.5-6.5; (5), selecting peters professional No.1 as the fertilizer; and (6), selecting the mixture of sphagna, pine bark, saw dust and peanut shells with the volume ratio of 1:1:1:1 in sequence as the base material. The sunlight greenhouse and the method provided by the invention have the benefits of being energy-saving and environment-friendly, having the dendrobium candidum survival rate up to 92%, effectively reducing more than 50% of manufacturing cost, and effectively solving the difficult problem that the planting cost of dendrobium candidum in the sunlight greenhouse in the north is high.

Description

technical field [0001] The invention belongs to the technical field of cultivation of traditional Chinese medicinal materials, and in particular relates to a solar greenhouse for cultivating dendrobium candidum and a cultivation method for dendrobium candidum. Background technique [0002] Dendrobium officinale is a perennial epiphytic herb of the family Orchidaceae. It is the best of Chinese medicinal materials. It has many functions such as nourishing yin and detoxifying, promoting body fluid and quenching thirst, improving eyesight and strengthening the body. It has a long history of application. In recent years, the market demand for Dendrobium candidum is increasing, and Dendrobium candidum is born on semi-shady rocks in mountains at an altitude of 500-1600 meters. It likes warm and humid climates and semi-shady and semi-yang environments. It stops growing below 0°C, and it is best to keep it above 0°C. Natural reproduction is slow, coupled with over-harvesting, wild re...

Problems solved by technology

[0003] Planting Dendrobium candidum in solar greenhouses in the north is especially hot in summer, and the cooling fan needs to be turned on for a long time during the day; in winter, especially in cold weather, it needs to be heated and kept warm at night, resulting in huge energy costs and low survival rate of Dendrobium candidum and other technical issues
