Air conditioning preservation method for Dendrobium

Abstract

The invention discloses an air conditioning preservation method for Dendrobium. The method comprises the following steps: 1) performing callus treatment; 2) suffocating in a big tent; 3) performing provisional planting preservation treatment; 4) packaging, namely putting the Dendrobium together with a provisional planting nutrition bottle into a plastic box or carbon in which a polyethylene (PE) preservative bag in the thickness of 0.02-0.05mm is lined; 5) precooling, namely precooling the Dendrobium which is packaged in the box in an air-conditioned cold store at the temperature of between -1 and 0DEG C for 12 to 24 hours; and 6) controlling air conditioning parameters, namely fastening the bag mouth of the PE preservative bag for the precooled Dendrobium, stacking in the air-conditioned cold store on routine, keeping the temperature at 0+ / -0.3DEG C, and ensuring that the volume percentage concentration of O2 in the air-conditioned cold store is 2 to 3 percent, the volume percentage concentration of CO2 is 8 to 10 percent and the relative humidity is 90-95 percent until the Dendrobium leaves the air-conditioned cold store. By the method, stems of the Dendrobium can be preserved for 8-12 months, leaves of the Dendrobium can be preserved for 3-5 months, the preservation time is greatly prolonged, and the market requirement is met.

Problems solved by technology

However, after drying, not only the weight of Dendrobium officinale will change, but also the active ingredients that are beneficial to the human body will be lost.

For this reason, people have adopted various methods to try to keep fresh Dendrobium, but at present the Dendrobium can only be preserved for 2 or 3 months at most, which is far from satisfying people's large demand for fresh Dendrobium
