Embodiment 1

[0019] 1) Use imported peat with a volume ratio of 3:4:2:1: coconut peat: vermiculite: perlite as a matrix, mix evenly, and fill it into a 72-hole tray. The size of the tray is 54cm long, 27cm wide, The depth is 5.5cm, and the tightness of the matrix is ​​kept consistent. The plugs filled with the matrix are placed on the seedbed in turn, 6 per square meter, and sterilized with 900 times the potassium permanganate solution; the dry density of the matrix 0.16, the total porosity is 90.90%, the large porosity is 30.60%, the small porosity is 60.30%, and the maximum water holding rate is 5.40. pH value 6.14, EC value 1.01, total nitrogen 1.16%, total phosphorus 548.47mg / kg, total potassium 8560.08mg / kg, calcium 2412.52mg / kg, magnesium 2397.79mg / kg, copper 20.87mg / kg, zinc 76.04mg / kg , boron 39.58 mg / kg, iron 5559.42 mg / kg, manganese 114.58 mg / kg, molybdenum 0.00 mg / kg, aluminum 15108.50 mg / kg, lead 11.58 mg / kg, sodium 3396.26 mg / kg, nickel 26.47 mg / kg, sulfur 1455.09mg / kg;

Abstract

The invention belongs to the technical field of plant propagation and particularly discloses a cuttage propagation method for Juniperus chinensis 'Plumosa Aurea'. The method comprises the following steps of: 1) uniformly mixing imported peat, coconut tree branny, vermiculite and pearlite in a volume ratio of (2-4):(3-5):(1-3):(0.5-2) which are taken as matrixes, and filling into a 72-hole plug; 2) picking lateral branches of female parents and cutting spikes in early March; 3) impregnating ear bases of cuttage branches for 2 seconds by using a Sensheng No.6 plant root promoter at the concentration of between 1,400 and 1,600ppm; 4) building an arch shed, and covering by using a plastic film; and 5) uncovering the film when the rooting rate reaches about 95 percent on the 95th day after cuttage, namely uncovering the film at both ends of the arch shed first and ventilating, and uncovering the entire film after 2 days and performing full exposure hardening. By the cuttage propagation method for the Juniperus chinensis 'Plumosa Aurea', the rooting condition is good, and the yield reaches over 95 percent; and the method is high in propagation speed, can adapt to climate and soil environments in China, and has good market prospect, and the propagation operation steps are simple.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and specifically relates to a method for cutting and propagating juniper juniper with golden feathers. Background technique [0002] 'Golden Feather' juniper Juniperus chinensis 'Plumosa Aurea', belonging to the genus Juniperaceae, is an evergreen coniferous tree, shrub, with dense branches, strong and powerful branches, arched extension, tree height 3-4m, crown width 2.5-4m; there are needles and scales, leaves The color is yellow-green in spring to autumn, and turns to bronze and yellow in winter, and the inner part of the crown is green; the cones are berry-shaped, green-brown. [0003] 'Golden Feather' juniper is light-loving, heat-resistant, drought-tolerant, air-pollution-resistant, likes well-drained soil, avoids stagnant water, and can be used as ground cover or hedge. It is widely used in urban greening and planting abroad, but it is still a brand new one in my country. This ...
