Cutting breeding method for osmanthus trees

Abstract

The invention discloses a cutting breeding method for osmanthus trees and belongs to the field of plant breeding. The method comprises the following steps: (1) collecting and treating cutting slips, namely collecting twigs from stock plants to serve as the cutting slips, cutting along the axial direction of larger ends of the twigs by using a cutter so as to form a cut, and performing rooting treatment; (2) performing seedling bed arrangement, namely arranging a seedling bed in a greenhouse, and spreading cutting media on the seedling bed; (3) performing cutting, namely inserting the cutting slips into the cutting medium layer, compacting and watering; (4) performing seedling stage management, namely watering with a nutrient solution once every 5-7 days when roots grow from the cut of the larger ends of the twigs, and maintaining corresponding temperature and humidity in the greenhouse; and (5) transplanting, namely transplanting within 2-3 months after cutting, thereby obtaining the seedlings. The cutting breeding method for osmanthus trees disclosed by the invention is simple in operation, the survival rate, seedling quality and emergence rate of cuttings of osmanthus trees can be effectively improved, the production cost is reduced, and the economic benefits are improved.

Description

technical field [0001] The invention belongs to the field of plant seedling raising, and in particular relates to a cutting seedling raising method of osmanthus fragrans. Background technique [0002] Osmanthus osmanthus tree, also known as Osmanthus osmanthus, is an evergreen tree of Osmanthus family. Osmanthus fragrans is native to the eastern part of the Himalayas in southwest China, and is also found in India and Nepal. It has a cultivation history of more than 2,500 years in China, and it is widely planted in the open field in the south of the Yellow River and in the southwestern part of Guangdong. Osmanthus fragrans is a long-sun plant, and it likes to grow in places with sufficient sunlight and thick, well-drained soil. The soil should be slightly acidic, with a pH of 5.5-6.5. Avoid alkaline soil, afraid of stagnant water and soot. Potted plants are needed in the north, and they can survive the winter in low-temperature greenhouses. The temperature around 0°C will ...

AI Technical Summary

Problems solved by technology

[0003] Osmanthus fragrans cuttage seedlings are generally favored because of their simplicity, fast growth and low cost. After survival, the root system is underdeveloped and the control conditions of the later management process are difficult to grasp and other technical difficulties. Therefore, the artificial cultivation of most osmanthus trees cannot form a set of standard and standardized planting and cultivation management models.
