Soilless culture method for promoting rapid flowering of seedlings of alpine rhododendron pink lady

Abstract

The invention relates to a soilless culture method for promoting rapid flowering of seedlings of an alpine rhododendron pink lady, wherein the seedlings of the alpine rhododendron pink lady are hybridoffspring seedlings of the alpine rhododendron pink lady; the method comprises the following steps of: preparing a culture medium; planting the hybrid offspring seedlings of the alpine rhododendron pink lady; carrying out bud removal treatment, transplanting, cultivation environment control, fertilization measures and watering measures. By adopting the soilless culture method for promoting rapidflowering of seedlings of the alpine rhododendron pink lady, the hybrid offspring seedlings of the alpine rhododendron pink lady can grow healthily, the plants are strong, the time from planting to flowering only needs 2 years and 7 months to 2 years and 8 months, and the flowering time is shortened by 1 to 2 years compared with the traditional planting method; the method can shorten the whole breeding period of the hybrid offspring of the alpine rhododendron pink lady by 2-4 years, and greatly shortens the breeding period of a new alpine rhododendron variety.

Description

technical field [0001] The invention relates to a soilless cultivation method, in particular to a soilless cultivation method for promoting the rapid flowering of alpine rhododendron pink beauties hybrid offspring seedlings. Background technique [0002] Rhododendron alpine, as a high-grade potted flower, has achieved large-scale localized production in my country. However, most of the alpine Rhododendron varieties planted industrially in my country are imported varieties, and the industrial development is limited. It is imminent to cultivate new alpine Rhododendron varieties with my country's self-cultivation intellectual property rights. However, the breeding cycle of new varieties of Alpine Rhododendron is too long and takes 10 to 15 years. The entire breeding process includes: parental selection and artificial pollination hybridization → hybrid seed sowing, seedling cultivation until hybrid offspring bloom → screening for good ornamental traits, adaptability Tissue cul...

However, the breeding cycle of new varieties of Alpine Rhododendron is too long and takes 10 to 15 years. The entire breeding process includes: parental selection and artificial pollination hybridization → hybrid seed sowing, seedling cultivation until hybrid offspring bloom → screening for good ornamental traits, adaptability Tissue culture and rapid propagation of an excellent single plant with strong sexuality→Cultivate tissue culture seedlings (excellent lines) to flowering→Determine stable and consistent excellent lines→Become a new plant variety and apply for new plant variety protection, and among them, the hybrid offspring The flowering cultivation of seedlings and the cultivation of excellent plant tissue culture seedlings to flowering are time-consuming, and usually it takes 3 to 5 years from the cultivation of hybrid offspring seedlings to plant flowering (Xie Weijia, etc., New Variety Selection of Rhododendron Alpine, Chinese Flower Horticulture, Issue 12, 2017, 44-45), it takes 3 to 5 years for tissue cultured seedlings to flower. For this reason, it is important to develop a cultivation method that promotes the rapid flowering of Rhododendron alpine seedlings to speed up the breeding work. significance

[0003] In addition, the traditional planting mode of alpine Rhododendron potted flowers planted with mulch plus pine needles, bark, red soil and other substrates has encountered problems such as difficulty in finding materials (mainly mulch), complex proportions, easy compaction of the soil, and many diseases.
