Problems solved by technology

Among them, the technical requirements of tissue culture are high, the operation is complicated, and the production cost is expensive; due to the slow growth of Photinia microphylla, only 2 to 3 branches can be cut as cuttings according to the conventional cutting propagation method, and the reproduction coefficient is very low; the above method limits the production of seedlings. Enterprises and nursery farmers carry out large-scale breeding of Photinia microphylla seedlings; using the cell totipotent regeneration function of plant organs, the cuttings of Photinia microphylla leaf buds are used, and the reproduction coefficient is more than 5 times higher than that of branch cuttings. The reproduction cost is low and the operation is simple; Literature search, there is no report in China

Abstract

The invention discloses a photinia lochengensis leafbud cutting seedling raising method. The method comprises the following steps that (1) proper cutting time is selected; (2) a cutting medium is prepared; (3) a rooting agent is prepared; (4) cutting slips are treated and cuttage is conducted; (5) management and transplantation are conducted after cuttage. According to the photinia lochengensis leafbud cutting seedling raising method, the cutting survival rate is over 95.6% and cost is reduced by 50% to 80% compared with that of a photinia lochengensis branch cutting method and only accounts for about 15% of cost of a tissue culture method. The photinia lochengensis leafbud cutting seedling raising method has the advantages that operation is easy and convenient, cost is low, the technical requirement is simple, popularization and application are easy, and the method has important application and popularization value in rapid propagation production of photinia lochengensis seedlings.

Description

technical field [0001] The invention relates to the technical field of plant vegetative propagation, in particular to a method for growing seedlings by cutting leaf buds of Photinia small-leaf. Background technique [0002] Photinia lochengensis is a variety of Photinia in the Rosaceae family. It is an evergreen shrub with short leaves, compact and dwarfed plants, bright red leaves in spring and autumn, and a long red leaf period. It grows normally in the south of Beijing and is cold-tolerant. Good, slow growth, low pruning cost, is an excellent ornamental ground cover plant, and has a broad market prospect for landscaping applications. [0003] Photinia small-leaf seedlings can be raised by tissue culture, cuttings and other vegetative propagation methods. Among them, the technical requirements of tissue culture are high, the operation is complicated, and the production cost is expensive; due to the slow growth of Photinia microphylla, only 2 to 3 branches can be cut as cu...
