Cultivation method for north America rhododendron

Abstract

Disclosed is a method for tissue culture of rhododendron. The tissue culture method comprises the steps that: step 1: rhododendron explant material is collected, and placed on a supper-clean bench after being treated; the rhododendron explant material is disinfected by alcohol with a concentration of 75 percent for 6 to 8 seconds, washed by sterile water for three times, disinfected by 0.001 litre of mercury for 6 to 8 minutes, and washed by sterile water for three times in order; step 2: the material after being disinfected and cut is implanted into bud induce culture medium for thirty days; 30 days later, the obtained material is then implanted into proliferation culture medium for 60 days; step 3: healthy and strong rhododendron seedlings cut with 2 to 3cm by height are implanted into a rooting culture medium for 45 days; step 4: after the newborn root of rhododendron is about 0.5 cm long, the culture medium attached to the root is cleaned and newborn root is moved into sterile thick sand, the air humidity of which is kept ranging from 75 percent to 85 percent; one week later, the newborn root is moved into the mixed material of turfy soil and perlite; 45 days later, the treated root is moved into the field where the root is under the shade for one week. The method can realize industrial culture of seedling within 6 to 7 mouths and mass production of shipshape nursery stock of rhododendron.

Problems solved by technology

And this kind of evergreen rhododendron in my country is mainly distributed in southwestern alpine regions such as Yunnan, Sichuan, and Guizhou. At present, there is a lack of cold-resistant evergreen rhododendron species in the central and northern regions of my country. Research on it, such as introduction and domestication, new Variety selection, breeding and promotion are also relatively lagging behind, unable to provide scientific and technological support for production application and market supply
