Soilless cultivation method to promote rapid flowering of Alpine Rhododendron Hongfenjiaren seedlings

Abstract

A soilless cultivation method for promoting rapid flowering of alpine Rhododendron rosacea seedlings, the alpine rhododendron rosacea seedlings described in the method are hybrid offspring seedlings of alpine rhododendron rosacea, and the method includes cultivation substrate preparation, alpine rhododendron rosacea hybridization Progeny seedling planting, bud removal treatment, transplanting, cultivation environment control, fertilization measures, watering measures. By adopting the method of the present invention, not only can the seedlings of the hybrid offspring of Alpine Rhododendron rosacea grow robustly, the plants will be strong, and the time from planting to flowering is only 2 years, 7 months to 2 years, 8 months, which shortens the flowering time compared with traditional planting methods 1 to 2 years can shorten the whole breeding period of alpine rhododendron pink beauty hybrid progeny by 2 to 4 years, and greatly shorten the cycle of alpine rhododendron new species selection and breeding.

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.
