The method can prevent grazing and trampling of grazing livestock on seedlings, ensures normal growth of main planting tree species-Siberian larch in the seedling stage, not only retains naturally updated seedlings, but also changes the woodland soil environment and forest stand structure, overcomes the limitation of naturally updated nature and grazing conditions, and accelerates forward succession of forest stands.
Description
Technical Field
The invention relates to a method for improving the updating and forestation effects of Larix albopictus, which promotes the updating of Larix albopictus and increases the population quantity of Larix albopictus.
Technical Field
Siberian larch (Larix sibirica Ledeb) belongs to evergreen needle-leaved trees, a special species in Xinjiang, and is a dominant species of natural forests in the mountainous region of Altai. However, the problem that the siberian larch is high in over-mature forest proportion and tends to age and degenerate in forest stands exists at present, meanwhile, the problems that natural updating is difficult and the survival rate of artificial forestation is not high exist for a long time, the influence of grazing is most direct, and mainly, young leaves and terminal buds of the larch are loved to be eaten by cattle and sheep and other livestock, and meanwhile, excessive treading is carried out, so that most of seedlings wither and die. The traditional fence enclosure only can realize seasonal protection, and has limited effect on natural updating and artificial afforestation of larch.
Juniperus sibirica Burgsd (Juniperus sibirica Burgsd) is creeping shrub of Juniperus in Cupressaceae, and is distributed in Altaishan mountain. The three leaves of Siberian juniper thorn leaves are regenerated, obliquely extended, coated in a needle shape or an elliptic needle shape, the tip of the needle is sharp or the upper part of the needle is gradually narrowed into a sharp tip, meanwhile, the tender branches and the leaves have special aromatic odor, and the characteristics ensure that the livestock can not eat or trample. Thus, juniperus sibirica is one of the major shrub species that are well conserved in altai mountains.
The invention utilizes the advantages and characteristics of the Siberian juniper, is applied to afforestation and updating of the Siberian larch, effectively improves the survival rate of the Siberian larch, promotes forward succession of the forest and provides technical support for protection and recovery of natural forests in Altai mountain.
Disclosure of Invention
The invention aims to provide a method for improving the renewal of the Larix sibirica in the west of the Altai mountain, which is completed by the steps of cleaning the selected land, planting the Juniperus sibirica and planting the Larix sibirica, thereby effectively improving the renewal and recovery effect of the Larix sibirica in the natural forest of the Altai mountain. The method is applied to afforestation and renewal of the Siberian larch by utilizing the characteristics of the Siberian juniper, adopting a mode of combining arbor and shrub and effectively improving the survival rate of the Siberian larch. The method not only retains naturally updated seedlings, but also changes the soil environment of the forest land and the structure of the forest stand, and accelerates the forward succession of the forest stand, especially the recovery of the Siberian larch population.
The invention relates to a method for improving the updating of Larix gmelinii in the western region of Altai, which is characterized by comprising the following steps:
a. selecting land and cleaning: selecting a Siberian larch seedling section with natural renewal or a planned artificial supplementary planting afforestation section in an Altai mountain natural forest, and cleaning sundry dead branches and stones within a range of 1.5m around the seedling and a planting point;
b. planting Juniperus sibirica: uniformly planting 3-5 2-3 annual Siberian juniper seedlings on a circumference with the radius of 20-30cm by taking Siberian larch seedlings or planting points as the circle center, wherein the distance between the outer edges of two adjacent Siberian juniper seedlings is 10-90cm, the branches of the Siberian juniper seedlings face outwards or along the circumferential direction during planting, and uniformly paving cleaned sundries and stones outside the Siberian juniper seedlings after planting;
planting Siberian larch: for the planned artificial supplementary planting afforestation Siberia larch section in the step a, after the planting of Siberia juniper is finished, 2-3 annual Siberia larch seedlings are uniformly planted in a circle;
c. after the afforestation is finished, water should be supplemented for 1 time immediately, the water irrigation amount is 3 liters per plant, and the nursery stock planting is carried out according to related afforestation regulations.
The principle of the invention is as follows: the juniperus sibirica can effectively prevent grazing livestock from gnawing and trampling seedlings of the juniperus sibirica, and by utilizing the characteristic, a mode of combining arborescent with shrub and afforestation is adopted for afforestation updating of the juniperus sibirica, so that the survival rate and normal growth of the juniperus sibirica are effectively protected and improved.
