Method for increasing survival rate of cuttage raised seedlings of leycesteria formosa

Abstract

The invention discloses a method for increasing the survival rate of cuttage raised seedlings of leycesteria formosa. The method comprises the following specific steps that (1) a cuttage seedling bedis prepared; (2) leycesteria formosa branches are collected, and semi-ligneous branches are cut into cutting slips of 10-15 cm at a cool place; (3) at 10-25 DEG C, the cutting slips are immersed intoa naphthalene acetic acid solution with the concentration of 1,000 mg / kg for 24 hours, and it is guaranteed that the portions, below stems and above stem nodes, of the cutting slips are immersed in the solution; (4) according to the plant line spacing of 10*10 cm<2>, the cutting slips are inserted into the cuttage bed; after cuttage, water is sprayed to the cuttage bed; (5) the cuttage bed is covered with a sunshade net rack with the height about 40 cm; (6) the condition of cutting slip buds is examined every week, spraying and water supplement are conducted in time, it is guaranteed that thehumidity in a greenhouse is kept 70% or above, and the air temperate of the cuttage bed is maintained within 10-35 DEG C. According to the method, the problem of difficult cuttage breeding of leycesteria formosa is well solved, and the method has very important significance on enlarging the group of leycesteria formosa, developing the varieties of new flowers, maintaining the genetic diversity ofleycesteria formosa and achieving standardized planting.

Description

technical field [0001] The invention relates to the field of cutting seedling raising, in particular to a method for improving the survival rate of wind blowing Xiao cutting seedling raising. Background technique [0002] Leycesteria formosa, also known as "Ghost Chuxiao", is a woody plant belonging to Lonicera genus and a unique plant in the Himalayas. It is produced in Yadong, Cuona, Longzi, Bomi, Zayu, and Linzhi. It grows at an altitude of 2500- 3200m warm and humid hillsides, valleys, creeks or riverside forests, forest edges or bushes, also produced in Guizhou, Sichuan, Yunnan, state-owned distribution in Bhutan, India, Nepal, Pakistan, etc., Australia, Europe, It is cultivated and naturalized in state-owned gardens such as North America and New Zealand. [0003] The first and second year old branches of Fengchuxiao are green, the trunk is hollow, shaped like a bamboo pole, the inflorescence is 5-20cm long, and it can make a sound when the breeze blows during the frui...

Problems solved by technology

[0013] Fengchuxiao is the original species of Guichuxiao, and the original species is usually propagated by seeds or cuttings. However, due to the small size of Fengchuxiao seeds, difficulty in obtaining them, and large variation, there are no relevant reports at home and abroad. , while in the preliminary experiment of cutting propagation, the highest emergence rate of the conventional method was only 5.6%.
