Dendrobium nobile culture moisture management device and application method thereof

Abstract

The invention relates to a dendrobium nobile culture moisture management device and an application method thereof. The invention discloses the dendrobium nobile culture moisture management device which comprises a water storage tank and a draining layer. The draining layer is arranged above the water storage tank; a gap is reserved between the water storage tank and the draining layer. The dendrobium nobile culture moisture management device has the following optimal modes that (1) the draining layer is hung above the water storage tank by a lifting rod; (2) a washer is arranged between the water storage tank and the draining layer; (3) the water storage tank is an underground layer, a plastic film is arranged in the water storage tank, then a rubble layer is paved on the plastic film, the draining layer is arranged on the rubble layer and a culture medium layer is paved on the draining layer; (4) the draining layer is a basin of which the bottom is provided with draining holes, and the water storage tank is a basin support. When the device is applied to carry out culture, a substrate layer is firstly drenched through, then water is filled into the water storage tank and the horizontal plane is in contact with the bottom of the draining layer or the position which is at a distance of 1 to 2 centimeters from the bottom of the draining layer; after the substrate layer is dried, watering is carried out again according to the manner. The device reduces watering times, ensures the ventilated, breathable, semi-half and semi-wet environment, isolates pest and disease damage to soil, is particularly suitable for dendrobium nobile culture and ensures yield and high quality of dendrobium nobile.

Description

technical field [0001] The invention belongs to the field of cultivation technology, and in particular relates to a water management device for cultivation of Dendrobium nodrobii and an application method thereof. Background technique [0002] Dendrobium is a perennial herb of Orchidaceae, which has the effects of nourishing yin and clearing heat, nourishing the stomach and promoting body fluid. Modern pharmacology shows that dendrobium has the functions of enhancing immunity, anti-aging, protecting liver and gallbladder, and anti-tumor. Dendrobium has high requirements on the habitat, and likes a ventilated, semi-dry and semi-humid growth environment. In artificial cultivation, in order to take into account the yield and the polysaccharide content of medicinal ingredients, the suitable growth temperature of Dendrobium is 25-30°C in the daytime, 15-20°C in the night, and the best humidity is about 80%, with good ventilation. [0003] At present, there are two main methods ...

Problems solved by technology

Although this method can ensure the ventilation of Dendrobium candidum and isolate soil diseases and insect pests, the disadvantage is that it is not conducive to the water retention of the substrate, especially in high-temperature areas such as Guangdong. Generally, it needs to be watered once every 2-3 days to ensure a humid environment. Nutrients are also prone to water loss during watering, adding cost and difficulty to management
