Cuttage and rapid propagation technology of photinia serrulata

Abstract

The invention relates to a cuttage and rapid propagation technology of nursery-grown plant, i.e., a cuttage and rapid propagation technology of photinia serrulata as color-leaf nursery stock. Photinia serrulata seedlings which are orderly in specification, good in quality, provided with matrixes during planting and short in rejuvenation period are produced by establishing a cutting orchard, carrying out cuttage on a steel-frame shed dish matrix, selecting the variety and the cuttage time, scissoring cutting slips, rooting agent variety and concentration, and erecting a small shed. Moreover, the dish-cuttage production capacity is large, and each steel-frame shed with an area of 667 m<2> can be used for carrying out cuttage on 0.2246 million of photinia serrulata cutting slips. The photinia serrulata has luxuriant foliage, is brilliant red and beautiful in young sprouts and tender leaves, and extremely good in ornamental effect; the quantity demanded for the number of seedlings is very large for the application on green fences, colored tapes and colored blocks, and therefore, the quantity of the seedlings for every 667 m<2> of colored block is 16700-30000. The cuttage and rapid propagation technology of photinia serrulata can be used for overcoming more or less flaws and defects in the existing process or facility, so that the demand for a plurality of seedlings on landscaping is satisfied.

Description

technical field [0001] The technology is a seedling cutting propagation technology, that is, a cutting rapid propagation technology of a colorful-leaf seedling Photinia fruticosa. Mainly through the establishment of ear-picking gardens, steel-frame greenhouses, plug matrix cuttings, selection of varieties, cutting time, cutting cuttings, types and concentrations of rooting agents, and erecting small sheds, the production of neat specifications, good quality, planting with substrate, and slow growth Short seedlings of Photinia fragrans. Moreover, the production capacity of plug cuttings is large, and 224,600 cuttings of Photinia fragrans can be cut for every 667 square meters of steel-frame greenhouses. It can meet the needs of a large number of useful seedlings in landscaping. Background technique [0002] Photinia frondosa is a plant of the genus Photinia in the family Rosaceae. It has luxuriant branches and leaves, and the new shoots and young leaves are red and beautifu...

AI Technical Summary

Problems solved by technology

[0004] 1. In terms of nursery facilities, multi-span greenhouses, micro-spraying systems, steel-frame seedbeds, brick-concrete seedbeds, etc., all have too much investment, which will inevitably increase the cost of seedlings;

[0005] 2. The use of full-substrate cuttings increases the cost;

[0006] 3. There is no container (tray) for seedling cultivation. It is difficult to transplant bare root seedlings, the survival rate is not high, and it is difficult to cultivate strong seedlings with well-developed root systems;

[0007] 4. Seedlings of the Red Robin variety grow faster, but the ornamental effect is poor, and the amount of pruning is increased by making color blocks and ribbons;

[0008] 5. There is no cutting orchard for picking branches, which limits the collection of cuttings and increases labor;

Although summer and autumn cuttings increase production, it is difficult to collect branches and requires a lot of labor, and the high temperature in summer also increases the difficulty of management;

[0010] 7. Use 8-10cm cuttings, wasting branches;

[0012] 9. The rooting agent treatment of cuttings, whether the base of the cuttings is aligned and immersed in the rooting agent for a few seconds, or the cuttings are soaked in the rooting agent solution for 0.5 to 48 hours, the operation is cumbersome and time-consuming
