Description
Technical Field
The invention relates to the technical field of plant cultivation, in particular to a method for manually pruning pinus sylvestris.
Background
The pinus sylvestris is one of the conifer species of the arbor with strong drought resistance and cold resistance, on arid dunes, the main root of the pinus sylvestris is generally deep-pricked for 1-2 m, the maximum depth can reach 4m, the side root is pricked for 50cm, the isolated wood root system extends to the periphery, the diameter can reach more than 13m, and the pinus sylvestris is the main afforestation species in northwest sand areas of Liaoning province, and is also the main conifer species of wind-proof sand-fixation forestation in northwest areas. The pine wood of the camphor tree is light and soft, can be used as building and shipbuilding materials, and can be used for manufacturing devices such as sleepers, ore pillars, electric poles and the like; high-quality aromatic oil can be extracted from needle leaves. Its advantages are high growth speed, high quality and wide application range.
After the pinus sylvestris grows for a certain period, partial redundant branches are inevitably generated due to the influences of insufficient moisture and nutrient and poor natural pruning capability, and the branches feel ill due to weakness, so that the stability of the whole stand is influenced. Therefore, for pinus sylvestris, the artificial pruning technique can effectively promote the growth of pinus sylvestris.
However, when the pinus sylvestris is manually pruned at present, the dead branches or weak branches at the lower part of the forest are mostly pruned manually according to experience, and the pruning is not performed according to the growth age, crown ratio, canopy density and the like of the pinus sylvestris, so that the growth of the pinus sylvestris is limited to a certain extent.
Therefore, how to comprehensively consider the growth condition of the pinus sylvestris and further provide a method for promoting the artificial pruning of the pinus sylvestris growth is a problem to be solved by the person skilled in the art.
Disclosure of Invention
In view of the above, the invention provides a method for artificial pruning of pinus sylvestris, which can adjust the individual proportion of the forest by adjusting the pruning time and the pruning strength of the pinus sylvestris and removing redundant branches, improve the water and nutrient conditions of the forest and strengthen the tree vigor and the resistance.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
the method for manually pruning pinus sylvestris is characterized by comprising the following steps of:
(1) Selecting pinus sylvestris in the young period of the fertile soil of the planting field;
(2) The pinus sylvestris of 1-6 ages is not pruned, and when 1-2 rounds of dead branches appear at the lower part of the crown, the first pruning is carried out until the closing degree reaches 0.7-0.8;
(3) When pruning is carried out in the step (2), the pruning intensity is divided into intensity pruning, medium pruning and weak pruning according to the crown ratio;
(4) And (3) when pruning, adopting the combination of thinning and cutting to remove too dense branches, mopping branches, overgrowth branches, crossing branches and pest branches in the inner bore of the crown, and cutting off overgrowth branches outside the crown.
The beneficial effects of the technical scheme are that: the pine needles planted at the fat soil position can quickly recover the growth of the tree after pruning, and the tree can be bred into knotless trees in a short time; the irregular branches within 1-6 years can ensure the high growth and the dry shape of the pine tree of the camphor tree; the canopy density reaches 0.7-0.8, which affects the growth environment of the lower branches of the pinus sylvestris, withers the branches, and the branches at the moment can avoid the lower branches from absorbing too much nutrition components of the pinus sylvestris, thereby preventing the growth; the tree is ventilated and transparent by thinning the branches, the tree body grows healthily and normally, and the tree crown is full by cutting off the overgrown branches outside the tree crown, so that the nutrition balance of the tree branch growth is maintained.
The planting density of the pinus sylvestris is 5000 plants/hm 2 。
Preferably, the pruning season is late autumn or early spring.
The beneficial effects of the technical scheme are that: in late autumn or early spring, sap stops flowing or does not flow yet, pruning does not affect the growth of the forest, and the color change and deterioration of the forest can be reduced.
Preferably, after the first pruning in the step (2), the pruning is performed again every 2-3 years. Dead branches are removed and living branches of 1-2 years are removed properly.
Preferably, in the step (3), the strong pruning is to prune branches with the height of less than 2/3, and the crown ratio is 1/3; moderately pruning is to prune branches with the height of less than 1/2 of the height of the tree, and the crown ratio is 1/2; the weak pruning is to prune branches below 1/3 of the height of the tree, and the crown ratio is 2/3.
Preferably, in the step (4), the thinning is performed by pruning the tree from the base, and the cutting is performed by pruning a part of the branch.
Preferably, the pruning incision is cut or broken, no stumps are left, the incision surface is smooth, and all the cut tree strips are carried away.
The beneficial effects of the technical scheme are that: the cut heals faster, insect damage can be reduced, decay can be prevented, and the resin can seal the cut quickly because the pinus sylvestris contains the resin, so that the cut naturally plays a role in organization, and the tree is transported away to prevent fire.
Compared with the prior art, the invention discloses a method for manually pruning pinus sylvestris, which has the following beneficial effects: the method is simple, clear in steps and good in planting effect, reduces the number of lower-layer consumed branches through manual pruning, avoids overgrowth of lateral branches, promotes trunk growth, forms a good tree shape, and increases the permeability of the lower-layer consumed branches through cleaning.
