Embodiment Construction

[0012] A sterilized seedbed is established on the selected breeding ground, an arch shed is built on the seedbed, and a sterilized cutting substrate is laid in the seedbed. The breeding ground should be in a place with good drainage, low groundwater level, convenient transportation, and abundant water sources, or use a single greenhouse and cover it with a plastic film. When inserting in spring or autumn, it should also be covered with a side film and a shading net. The seedbed is leveled, the height difference between the center and the edge of the bed surface is less than 2cm, the width of the seedbed is 100cm, and the length is generally 20-30m, and the height of the seedbed is about 12cm. The shed film is made of moso bamboo sheets with a length of 2.1m and a width of 2cm, and the thickness of the plastic film is 4 wires. The cutting substrate is vermiculite, or sieved yellow heart soil, or a layer of coarse sand on the bottom, and a layer of yellow heart soil mixed with f...

Abstract

The present invention belongs to the field of plant cultivating technology. The cuttage process of photinia frasery includes the following steps: forming seedling bed, building arced shed and spreading medium for cuttage; picking from the mother body semi-lignified young follage or the same year branch for cutting shoot and cutting into cuttage branch of 3-4 cm length with one bud; treating the cuttage branch with rooting agent; planting in the medium of seedling bed in the depth of 2-4 cm and proper density; watering, spraying germicide to branch and leaf, covering with plastic film and shading net and management after planting. The said process has survival rate as high as 90-95 % and fast propagation speed in obtain excellent photinia frasery.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a cutting propagation method of Photinia fruticosa. Background technique [0002] Photinia frasery is a cultivar of the genus Photinia in the family Rosaceae, belonging to small evergreen broad-leaved trees. Single leaf, alternate, old leaf leathery, leaf surface dark green with luster, leaf underside green, smooth and colorless; leaf elliptic-lanceolate, 6-12cm long, 2.8-4cm wide; new shoots and new leaves bright red; terminal Corymb panicles, 10-18cm long; small white flowers, about 0.85cm in diameter; flowering period from early April to early May; pome, red, 0.6-0.85cm in diameter, mature in late summer, and can bear fruit until the next spring. Photinia fragrans likes well-drained soil, has no strict requirements on soil pH, likes fertile and loose soil, and has a strong ability to tolerate barrenness. It can also grow on cla...
