Background
Rhododendron is one of ten flowers in China, and China has extremely rich wild germplasm resources. Alpine rhododendron refers to a plurality of leather, evergreen and large-crown varieties which are bred by using rhododendron germplasm resources in evergreen rhododendron. The alpine rhododendron is also a famous and famous woody flower in the world, and has high ornamental value and economic value.
The seedling is the first element of potted flower production. In order to match with the matched production technology of rhododendron lapponicum potted flowers and improve the production efficiency, a grower needs to transplant the rhododendron lapponicum potted seedlings into the flowerpots in spring, namely 3-5 months, and the seedling producer is required to provide qualified seedlings in the period. At present, potted rhododendron alpinum is used for tissue culture of seedlings in large-scale production, and the production process comprises the steps of explant disinfection, bottle filling, sterile material propagation, rooting, transplanting and outplanting. Using 20 bundles of 1 bottle of propagation seedlings as materials, cutting the propagation seedlings into single pieces, rooting in the bottles (30-40 days), then exercising in a rooting bottle seedling shed (7-10 days), finally transplanting into 105 plug trays for culturing (culture medium is filled in the plug trays) (150-180 days) for 3 links, and producing qualified seedlings and grown seedlings 24-32 in 187-230 days. In the production time, the bottle seedlings which are rooted need to be transplanted into the culture medium at the latest in the first 11 months, and then the bottle seedlings are cultivated in a greenhouse or a greenhouse, so that the seedlings can be guaranteed to be outplanted in the next spring (3-5 months), and the requirement of the market on the seedlings is met.
