A kind of alum root cutting fast propagation method

Abstract

Disclosed is an alumroot cuttage rapid propagation method. The method comprises the steps that an alumroot female parent garden adopting a container cultivation mode is built, the garden is built inside a plastic greenhouse with the shading coefficient being 50%, and the temperature inside the greenhouse is 6-35 DEG C; a cutting medium is formed by mixing coco coir, turf, vermiculite and perlite with the volume ratio being 2-3:1:0.5:0.2-0.5; the cuttage time is the first ten days of March to the middle ten days of October; leaf stalk roots of mature leaves of alumroot female parents together with buds are sheared as cutting slips; after disinfection treatment is performed on the cutting slips, the cutting slips are dipped into a rooting agent containing naphthylacetic acid and indolebutyric acid and then are subjected to cuttage into tree aperture disks, the aperture disks are placed on a seedbed inside the greenhouse, a small shed is installed on the seedbed, the shading coefficient inside the small shed is 70-80%, and the relative air humidity is 80-90%; seedling hardening is performed. By adopting the method, after cuttage is performed for 39-58 d, the planting percentage reaches 95% or above, the rooting situation is good, the cost is low, operation is easy, sprout characters are stable, and sprouts can be produced in a large-scale and standardized mode.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a convenient and efficient alum root cutting propagation method. Background technique [0002] Heuchera micrantha (Heuchera micrantha), also known as coral bell, is a perennial herb of the saxifrage family Heuchera micrantha, distributed in central America, with basal leaves, broad ovate, heart-shaped or wedge-shaped base, palmately lobed to deeply lobed, wavy edges, It likes neutral to acidic, loose, fertile and well-drained soil, likes sun and tolerates shade. Alum root has become a common understory ornamental plant in European and American gardens because of its colorful leaves (leaf colors are red, purple, yellow, bronze, green, orange, etc.), cold resistance, and drought resistance. . In recent years, with the development of my country's ornamental horticulture industry, people's attention to new and excellent flower species has increased unprecedent...

Problems solved by technology

However, most alum root varieties are difficult to bear fruit; the reproduction coefficient of ramets is extremely low, and large-scale production cannot be performed, and the plant sizes after ramets are different, which affects the uniformity; the cost of tissue culture propagation is high, the process is cumbersome, and the cycle is long, so it is difficult to quickly form a mass of seedlings
