Cutting propagation technique of photinia fraseri

Abstract

The invention discloses a cutting propagation technique of photinia fraseri, and belongs to the technical field of agriculture. The cutting propagation technique is implemented through the following steps that 1, 50% wettable powder is mixed with soil according to the specification of 1.5 g / m<2> and also can be prepared into chemical soil to be spread on a seedling bed, and then cutting plants are cut off; 2, small branches on the two sides of each cut-off cutting plant are cut off; 3, notches are sterilized and disinfected, wherein the notches are soaked with a 0.1% potassium permanganate solution at 30 DEG C and then taken out to be washed clean with clear water; 4, the cutting plant notches are put into a 60%-70% indoleacetic acid induction growth agent solution to be soaked for 1-2 minutes and then taken out for cutting; 5, dry land is adopted as the cutting land; 6, the cutting plants are inserted into soil for vertical cutting, the insertion depth is 8-20 cm, and root mud is compacted; 7, 4 g of 75% quintozene and 5 g of zineb are applied to per square meter of the nursery land, mixed and then mixed with 12 kg of fine soil to be uniform, lower padding and upper covering are adopted during cutting, and the mixture has the special effects on blight, sclerotiniose, damping off, anthracnose and the like.

Description

technical field [0001] The invention relates to the cutting propagation technology of Photinia frondosa and belongs to the field of agricultural technology. Background technique [0002] Photinia red leaf (scientific name: Photinia × fraseri) is a collective name for the hybrid species of Photinia in the family Rosaceae. It is an evergreen small tree with a plant height of 4-6 meters. The leaves are leathery, oblong to obovate-lanceolate, and the new leaves are red in spring. Green, red in autumn, winter and spring, the color of frost is thicker, and the color of low temperature is better. As a street tree, its pole stands like a torch; as a hedge, its shape lies like a fire dragon; with pruning and landscaping, its shape can be in various poses and with different expressions, and the landscape effect is beautiful. Photinia is named for its bright red shoots and young leaves. There are two common varieties, red robin and red lip, among which red robin has bright and eye-ca...
