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

Embodiment 1

[0036] Rapid Propagation of Cuttings of Alum Root Variety 'Mamaredu'

[0037] 1 Female parent nursery construction and female parent management

[0038] 1.1 Construction of female parent nursery

[0039] Set up alum root female ear picking nursery in a well-ventilated plastic greenhouse that is not easy to accumulate water. The greenhouse has a span of 8 meters, a bay of 4 meters, and a shoulder height of 4 meters. A layer of shading nets with a shading rate of 50% that can be manually opened and closed is installed inside. , The ground of the greenhouse is covered with black ground cloth to prevent the growth of weeds. A drainage ditch with a depth of 30 cm and a width of 40 cm is set every 8 meters (each span) on the ground of the greenhouse. The bottom of the drainage ditch is provided with a 3% slope to facilitate the drainage of accumulated water. The temperature in the plastic greenhouse with the shading rate controlled at 50% is between 6 and 35°C, the highest temperat...

Embodiment 2

[0055] Cutting Rapid Propagation of Example 2 Alum Root Variety 'Plum Pudding'

[0056] Embodiment 2 is the same as Embodiment 1 except that the following measures are different, and will not be repeated here.

[0057] 1.2 Maternal management

[0058] A. The female parent of alum root 'plum pudding' is planted in 6L (pot diameter 23cm, pot height 18cm) PP flower pots, and the density of flower pots is 3800 pots / mu. The cultivation substrate is formed by mixing coconut bran, peat and perlite according to the volume ratio of coconut peat: peat: perlite is 2:1:0.2, the pH value of the cultivation substrate is 6.0~6.5, and the EC value is 1.3~1.5 ms / cm.

[0059] B. The amount of controlled-release fertilizer topdressing the female parent of alum root 'plum pudding' every 6 to 8 months is 16g / pot.

[0060] 2.2 Preparation before cutting

[0061] The cutting matrix is ​​composed of coconut bran, peat, vermiculite and perlite in a volume ratio of 3:1:0.5:0.2 of coconut bran: peat...

Embodiment 3

[0065] Cutting rapid propagation of embodiment 3 alum root variety ' tiramisu '

[0066] Embodiment 3 is the same as Embodiment 1 except that the following measures are different, and will not be repeated here.

[0067] 1.2 Maternal management

[0068] A. The female parent of alum root 'Tiramisu' is planted in a 4L (pot diameter 21cm, pot height 16cm) PP material flower pot, and the flower pot placement density is 4000 pots / mu. The cultivation substrate is formed by mixing coconut bran, peat and perlite according to the volume ratio of coconut peat: peat: perlite is 1:1:0.2, the pH value of the cultivation substrate is 6.0~6.5, and the EC value is 1.3~1.5 ms / cm. The female parent of 'Tiramisu' is updated every 3 years.

[0069] B. The female parent of alum root 'Tiramisu' is topdressed with controlled-release fertilizer every 6 to 8 months, and the amount of application is 12g / pot.

[0070] 2.2 Preparation before cutting

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...
