Method for planting photinia fraseri dress

Abstract

The invention discloses a method for planting photinia fraseri dress. The method comprises the following steps of (A) seed pretreatment; (B) substrate preparation; (C) seedbed leveling; (D) sowing andearthing; (E) nursery management; (F) sapling transplanting; (G) sampling raising, management and protection. According to the method for cultivating and planting the photinia fraseri dress, the germination rate of seeds is 97.8%, the germinative force is 96.5%, 30 days after germination, the survival rate reaches up to 98.9%, three months after sowing, the number of the photinia fraseri dress seedlings with 90%-110% of average seedling height accounts for 90.3% of the total number of the photinia fraseri dress, and the number of the photinia fraseri dress seedlings with 90%-110% of average ground diameter accounts for 96.3% of the total number of the photinia fraseri dress.

Description

technical field [0001] The invention relates to the technical field of agriculture and forestry seedling cultivation. More specifically, it relates to a method for planting Photinia frondosa. Background technique [0002] Photinia is an evergreen small tree or shrub, named for its bright red shoots and young leaves. In spring and autumn, the new shoots and young leaves of Photinia fragrans are fiery red, with bright and lasting colors. During the high temperature season in summer, the leaves turn bright green and feel fresh and cool. Therefore, Photinia fragrans has been widely cultivated in many places in China. The propagation of Photinia fragrans mostly adopts the method of cutting propagation. This is because the seeds of Photinia frondosa have a dormant period, the germination rate of sowing propagation is low, and the survival rate after germination and transplanting are relatively low, which limits the cultivation of Photinia fragrans by sowing. Large-scale propag...

AI Technical Summary

Problems solved by technology

The propagation of Photinia fragrans mostly adopts the method of cutting propagation. This is because the seeds of Photinia frondosa have a dormant period, the germination rate of sowing propagation is low, and the survival rate after germination and transplanting are relatively low, which limits the cultivation of Photinia fragrans by sowing. Large-scale propagation of Photinia fragrans

[0003] In the prior art, the seeds of Photinia fragrans are usually collected in October of each year, stored in sand until March of the second year, and then can be sown after the seeds are processed; Tooth survival rate and transplanting survival rate are still relatively low, and it is not suitable for large-scale promotion and reproduction in forestry.
