Abstract

The invention discloses a supertree planting method and belongs to the technical field of afforestation. The supertree planting method comprises the five steps of choosing afforesting land, cutting down and burning grass on maintains, preparing land with ditch zones, transplanting supertrees and fostering and managing the supertrees. By means of the step of burning grass on the maintains and the step of preparing the land with the ditch zones, quick-acting nutrients are greatly improved, the soil fertility is improved, noxious animals can be repelled, diseases and insect pests are reduced, forest sanitary conditions are improved, a deep structure of soil is improved, permeable breathability and water-conservation fertilizer-storage capacity are reinforced, microbial activities are improved, the soil fertility is improved, and supertree root development and quick growth of overground parts of the supertrees are facilitated. Thus, the planting survival rate can be more than 95%. Furthermore, tree seedlings can grow quickly after being transplanted. When the supertree seedlings grow for three years, the average height of the trees can reach 5.2meters. By means of the supertree planting method, large-scale supertree afforestation can be developed, the problem that existing supertree resources are in lack is solved, industrialization is achieved, and good ecological benefits and economical benefits can be obtained.

Description

One is held up a day tree cultivation method

Technical field

The present invention relates to Forest-tree culture technical field, be specifically related to a kind of day method for tree culture technique of holding up, belong to afforestation technology field.

Background technology

Hold up day tree (Parashorea Chinensis Wang Hsie) Dipterocarpaceae Parashorea, megaphanerophyte, high 40-70 rice, diameter of a cross-section of a tree trunk 1.3 meters above the ground 60-160 centimetre, bark grey or sepia, trunk top be shallow lobe, straw bag bottom is bulk and peels off, sprout is by lepidiod fine hair, the circular hole skin of tool, leaf keratin, ellipse or ellipticity lanceolar, according to expert investigation examination, only deposit several thousand strains at ground ball clay, be mainly distributed in the ground such as Napo County, Ba Ma county and Daxin County in Yunnan Province of China province Xishuangbanna and southwest, osmanthus, Guangxi Zhuang Autonomous Region.

Hold up that it trees material is hard, durable, rotproofness is strong, be not subject to damage by worms; Wood color is isabelline; without special odor; texture is straight, even structure, handling ease; slicing face is smooth; decorative pattern is attractive in appearance, is the quality material of manufacturing various top-grade furnitures, plywood and industrial wood, bridge, building, musical instrument, sports apparatus etc., has Important Economic and is worth and scientific research value; there is good development prospect, be listed in country-level rare and protected trees.

Owing to holding up, it tree existing resource is little, blossom and bear fruit evening again at age, the general diameter of a cross-section of a tree trunk 1.3 meters above the ground reaches more than 40 centimetres just blossoms and bears fruit, it is not again all to blossom and bear fruit every year simultaneously, but the 2-5 of being separated by just blossoms and bears fruit once, in addition seed longevity is short, is multiplied into tree very difficult by natural germination, must development artificial afforestration technology.

Summary of the invention

goal of the invention: the object of the invention is for problems of the prior art, provide one to hold up a day tree cultivation method of forestation.

technical scheme: day tree cultivation method of holding up of the present invention, specifically comprises the following steps:

1, planting site is selected: select 600 to 1000 meters of height above sea level, and hidding and sunny side, soil layer is deep, and quality is loose, is rich in organic matter, acid reaction, moistening and well-drained mountain depression hillside fields;

2, cut grass refining mountain: choose after planting site, cut down ground weeds shrub to dry from lower to upper 9～October, then holds fire line successfully in forest land surrounding, selects calm cloudy day or morning, the mountain of igniting refining from outside to inside from top to down, behind refining mountain, remaining limb, toothed burclover, butt will concentrate bunch to burnout;

3, wholely: planting site adopts ditch band method of soil preparation, from bottom to top along the soil digging of hillside horizontal direction trench digging, show native cubsoil separately, descending at ditch builds up the low bank of earth between fields with cubsoil, upward slope is shown to mamoty after ditch is held successfully and is filled in ditch, fills up and slightly becomes ridge shape, dig Article 2 trench by 1.8～2 meters of afforestation line-spacings again, 60～70 centimetres of furrow widths, then dig 50 × 50 × 40 ㎝ planting holes by 1.5～1.8 meters of spacing in the rows in ditch by dark 50 centimetres;

4, transplant: early spring, late March was to early April every year, fine day after selection cloudy day or rain, with one year seedling transplanting, more than height of seedling requires 35 ㎝, while planting seedling, want righting nursery stock, dark 2～4 ㎝ left and right, the former rhizosphere of depth ratio place, earthing is careful, compaction in layers, cave face covers and loosens the soil, be above the ground level, become turtleback shape, prevent ponding;

5, tending management: afforest and carry out then weeding bushing autumn and foster once, remove weeds in cave, the expansion cave of around digging, cave, Second Year is respectively fostered once in spring and autumn respectively, fosters at every turn and wants comprehensive weeding, loosens the soil, the training root and stem of certain plants, weeding in summer in the 3rd year, cut assorted, the table earth culture root and stem of certain plants, weeding in autumn, cut assortedly, the 4th year with backsight closing of crop situation, carries out every year cutting weeds 1～2 time.

beneficial effect: compared with prior art, its beneficial effect is in the present invention:

Day tree cultivation method of holding up disclosed by the invention, adopt refining mountain and ditch band method of soil preparation, refining mountain can roll up quick-acting nutrient, increase soil fertility, and be conducive to drive away noxious animal, reduce damage by disease and insect, improve forest land sanitary condition, and the whole ground of ditch band can change the clay fertilizer soil of filling in a form, add chiselling layer, improve the deep structure of soil, add highly permeable venting capability and water conservation and hold fertile ability, promote microbial activities, thereby improve the fertility of soil, be conducive to hold up day root system development and an acrial part Fast Growth for tree, therefore cultivating survival rate reaches more than 95%, and sapling is transplanted rear growth rapidly, hold up day sapling wood and grow to 3 years when raw, set equal height and reached 5.2 meters, with this method can large area development hold up day tree afforestation, alleviate and hold up day rare situation of tree existing resource, form industrialization, the ecological benefits that obtained and economic benefit.

embodiment

Below in conjunction with the concrete example of implementing, technical solution of the present invention is elaborated.

Production address: De Long township, Napo County, Guangxi Zhuang Autonomous Region.
