Embodiment 1
[0020] 1) Select a suitable breeding ground to establish the ear picking nursery in the female parent area of the dwarf cypress cypress. The ratio is 4:4:2:1 reed moss: yellow heart soil: perlite: organic fertilizer is mixed evenly as the matrix, and the matrix is filled into the seedbed to keep the tightness of the matrix. The thickness of the matrix is 8cm. Use it 24 hours before cutting 800 times the potassium permanganate solution and disinfect the substrate; the dry bulk density of the substrate is 0.53, the total porosity is 52.76%, the large porosity is 8.66%, the small porosity is 44.10%, the maximum water holding rate is 1.01, and the pH value is 5.97. EC value 3.02, total nitrogen 1.82%, total phosphorus 2435.22mg / kg, total potassium 6456.75mg / kg, calcium 1585.32mg / kg, magnesium 750.24mg / kg, copper 26.24mg / kg, zinc 201.01mg / kg, boron 38.27 mg / kg, iron 4203.56 mg / kg, manganese 222.34mg / kg, molybdenum 6.41mg / kg, aluminum 22241.03mg / kg, lead 26.87mg / kg, sodium 26...

Abstract
The invention relates to a cuttage propagation method for juniperus procumbens 'Nana', and belongs to the technical field of plant propagation. The cuttage propagation method is characterized by comprising the following steps of: 1) filling reed jasmine, yellow subsoil, pearlite and an organic fertilizer which serve as matrixes in a volume ratio of (3-5):(3-5):(1-3):(0.5-1.5) into a seedling bed;2) shearing spikes of an autumn tip in the previous year from a lateral branch of a juniperus procumbens 'Nana' female parent, wherein cuttage is performed appropriately in the first ten days of March; 3) infusing roots of cuttage branches formed by cutting the spikes in 2,400 to 2,600 ppm of No.8 sensheng plant rooting agent for 2 to 3 seconds; 4) performing cuttage by using the seedling bed, and performing management and maintenance; and 5) when a rooting rate is about 60 percent, performing seedling refining. By the cuttage propagation method for the juniperus procumbens 'Nana', a rooting condition is good, and yield is over 60 percent; when the method is used, the juniperus procumbens 'Nana' easily propagates and propagation speed is high; and the juniperus procumbens 'Nana' can adapt to the climate and the soil environment of China and has a good market prospect.
Description
technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a cutting propagation method for dwarf cypress cypress. Background technique [0002] Dwarf cypress Juniperus procumbens 'Nana', Cupressaceae, Juniper genus, evergreen coniferous tree, dwarf shrub, creeping and spreading horizontally, branches curved and extending laterally, compact, layered, growing slowly and felt like flakes, bark brown, tree height 0.20m-0.50m , the crown width can reach 1.8m-5.0m, the bark is brown; there are needles and scale leaves, the leaf color is blue-green, green, gray-green, yellow-green in the growing season, and it is mainly blue-green in winter, turning slightly Purple, fragrant after crushing; cone-berry shape, light blue, small and round. [0003] Dwarf paving cypress enjoys light conditions, has strong resistance to a variety of soil adversities, can grow normally in slightly acidic, neutral and slightly alkaline soils,...
