Problems solved by technology

Especially red-skinned spruce. At present, there are few studies on the cutting propagation of red-skinned spruce, mainly including: the cutting propagation technology of red-skinned spruce (Zhao Lihui et al., "Journal of Northeast Forestry University", Vol. 25, No. 1) ; Afforestation experiment of red spruce cutting seedlings (Fu Linxue et al., "Forestry Science and Technology", Vol. The whole set of cutting cultivation techniques has not been reported yet

Embodiment 1

[0027] The planting method of red bark spruce is characterized in that the method comprises the following steps:

[0028] (1) Slotting bed configuration and management: Select the substrate as humus + perlite + vermiculite + chicken manure in a weight ratio of 4:3:2:1, and spray 0.2% carbendazim on the well-stirred substrate On the ground, carry out sterilizing treatment, make a slotting bed with a length of 4.5-5.0m, a width of 1.5-2.3m, and a thickness of 0.35-0.40m in the greenhouse or in the open field, and sterilize it with 1.5‰ potassium permanganate solution 2 days before inserting. The dosage reaches the bottom of the slotting bed until the liquid medicine flows out. 1 day before the cutting, start the spray device to drench the bed to reduce the acid, alkalinity and salt ion concentration of the substrate, and then disinfect and sterilize it again with 0.2% carbendazim liquid. ;

[0029] (2) Collection of cuttings: In the first ten days of June, cut off the twigs tha...

Embodiment 2

[0042] Cuttage planting method is the same as embodiment 1, and difference is only that the composition of rooting nutrient solution is:

[0043] IAA 0.9g / L

[0044] NAA 7.5g / L

[0045] KT 3.2g / L

[0046] ABT-6 0.3 g / L.

Embodiment 3

[0048]Cuttage planting method is the same as embodiment 1, and difference is only that the composition of rooting nutrient solution is:

[0049] IAA 0.7g / L

[0050] NAA 6.0g / L

[0051] KT 3.5g / L

[0052] ABT-6 0.2 g / L.

[0053] The above implementation

[0054] In the above-mentioned implementation mode, the rooting rate of embodiment 1 reaches 97%, and the survival rate reaches 96%, and the rooting rate of embodiment 2 reaches 97%, and the survival rate reaches 97%, and the rooting rate of embodiment 3 reaches 98%, and the survival rate It can reach 99%, accelerate the speed of seedling breeding, and ensure the growth of red spruce and the sustainable use of resources.

Abstract

The invention discloses a method for planting Picea koraiensis, which includes cutting bed arrangement and management, cutting collection, cutting treatment, cuttage, post-cuttage management, transplanting and post-transplanting management. The complete method for planting Picea koraiensis is more complete and systematic than the prior art, and the final survival rate reaches more than 96%. A series of preparations contributes to differentiation of root primordium into adventitious roots, so that cuttage survival rate is increased. A certain proportion of matrix contributes to thermal insulation, water absorption, water permeation and ventilation, and pathogenic bacteria are few and rooting is fast.

Description

technical field [0001] The invention relates to a method for planting plants, in particular to a method for planting red bark spruce. Background technique [0002] Red spruce ( Picea koraiensis Nakai) also known as red smelly, is an evergreen tree of the genus Spruce in the family Pinaceae. , multi-radiating extension, diamond-shaped cross-section, and stomatal lines on all sides. Cones ovoid-cylindrical or cylindrical-oblong-round, greenish-yellow brown or brown after ripening; seed scales are thin and woody, triangular-obovate, with membranous long wings on the top of the seeds. Distributed in the Northeast Xiaoxing'an Mountains and Jilin Mountains at an altitude of 1400--1800 meters, it is also produced in North Korea and Ussuri. More shade tolerant, shallow rooted. It has strong adaptability and can grow under different site conditions in the distribution area except swampy areas and dry sunny slopes and ridges. This tree species has graceful posture, ornamental ch...
