Abstract
The present invention is that one utilizes mulch film to carry out the dry method of forestation of Tectona grandis L. F. undercut, manages including after the preparation of kind of plant hole, the afforestation preparation of nursery stock, seedling growth and plantation, 10～dig November and plant plant hole, and apply base manure, return good soil；December～March in next year, when kind plant hole moistens after rain, select prepare afforestation strong sprout；Cut off trunk after seedling growth at distance Seedling butt portion 3～5cm, spread fertilizer over the fields slow-release fertilizer, covering with plastic film；Depending on seedling growth situation, first on mulch film, open an osculum, finally lift except mulch film, prune and sprout branch.The present invention covers black micropore water-permeability plastic film above nursery stock, can seep water, ventilate, be incubated, moisturizing, the effect of suppression weed growth, the precipitation of little rainfall can penetrate into mulch film soil under by the micropore on mulch film, separately because of the full nitrogen in soil under black plastic mulching raise crop, organic matter, available potassium, spatter the nutritive indexs such as solution nitrogen, than the raising having in various degree covering hyaline membrane, 1 year raw trees are than averagely improving 20～30cm without cutting the dry nursery stock height of tree, footpath, ground averagely improves 0.3～0.5cm, and survival rate improves 4～6%.
Description
Technical field
The invention belongs to forest afforestation technology field, relate to one and utilize mulch film to carry out the dry method of forestation of Tectona grandis L. F. undercut.
Background technology
Tectona grandis L. F. (Tectona grandis L.F.), belongs to Verenaceae Tectona and partly falls leaves megaphanerophyte, Tectona grandis L. F. core material ratio
Greatly, in crineous, the most pest-resistant, pole corrosion resistant, water-fast, fire-resistant, Drought-wet change significantly in the case of do not stick up and do not split, easily process,
Purposes is extremely wide, and decorative pattern is beautiful in addition, is described as one of most important torrid zone commerical tree species in the world, with conifer, eucalyptus globulus class,
Poplar class is listed as in the wealthy Tree Species of Plantation of pin in the world cultivating one of most common seeds, is also most popular on international market
One of hardwood seeds, international lumber market price is the highest.
Tropical Foresty Inst., Chinese Academy of Foresty Sciences's long campaigns Tectona grandis L. F. is introduced a fine variety, fine-variety breeding and cultivation technique etc.
Systematic study, Tectona grandis L. F. saves in China Hainan, Yunnan, Guangxi, Guangdong and Fujian etc. all the popularizing planting of larger area.In recent years
Guangxi forest-science academy assume responsibility for the research project in terms of the stony desertification comprehensive control of multinomial karst area, introduction and cultivation table for many years
Bright, Tectona grandis L. F. shows well adapting to property to Guangxi Karst Region, and increment exceedes many local indigenous trees, and Tectona grandis L. F.
Like calcium, growth is rapid, dry branches and fallen leaves amount is big, is the first-selected seeds administering stony desertification.
Summary of the invention
It is an object of the invention to the blank for the dry method of forestation of Tectona grandis L. F. undercut, it is desirable to provide one utilizes mulch film to carry out Fructus Citri grandis
The wood dry method of forestation of undercut.
It is an object of the invention to be achieved through the following technical solutions:
One utilizes mulch film to carry out the dry method of forestation of Tectona grandis L. F. undercut, including preparation, the afforestation preparation of nursery stock, the nursery stock kind of kind of plant hole
Manage after planting and planting, it is characterised in that: select container seedling to afforest, block trunk after plantation, spread fertilizer over the fields slow-release fertilizer, finally exist
Covering with plastic film above nursery stock, mainly uses following steps:
(1) plant the preparation of plant hole: 10～dig November and plant plant hole, apply base manure, return good soil；
(2) preparation of afforestation nursery stock: December～March in next year, when kind plant hole moistens after rain, selects prepare afforestation strong sprout；
(3) seedling growth: block trunk after seedling growth, spreads fertilizer over the fields slow-release fertilizer, covering with plastic film；
(4) manage after plantation: regarding seedling growth situation, first on mulch film, open an osculum, finally lift except mulch film, prune and sprout branch.
The preparation method of above-described kind of plant hole is to dig length: 50～60cm, width: 50～60cm, deep 45～the kind of 50cm
Plant hole, often spreads manuer in holes 1～1.5kg calcium magnesium phosphate and 1.5～2kg chicken manures make base manure, returns soil higher than plantation pocket 2～3cm, plant
Line-spacing is 2.5 × 3.0m or 2.0 × 4.0m.
The preparation method of above-described afforestation nursery stock is the container seedling of selectively footpath >=0.6cm, soaks with Coptotermes formosanus Shtrari. medicinal liquid
Nursery stock root 3～5 minutes.
After above-described seedling growth method is seedling growth, distance blocks trunk at Seedling butt portion 3～5cm, is holding
Device cup surrounding spread fertilizer over the fields 5～10g fertilizer efficiency be 5～6 months, N:P:K be the Ai Beishi slow-release fertilizer of 16:6:12, then earthing, only stay master
Dry top 1～3cm is exposed at outside soil, covers length 40～50cm, wide 40～the mulch film of 50cm, with earth mulch film above nursery stock
Surrounding is compacted.
Above-described mulch film is aperture 2～3 microns, 500～1000 holes/m2Black micropore water-permeability plastic film.
Above-described lift except the method for mulch film when being rudiment length 1～2cm of mid-April～nursery stock in the first tenday period of a month in May nursery stock
Directly over open one long and wide be 1～2cm osculum, allow rudiment expose outside mulch film, late June～late July lift except ground
Film, retain comparison upright, sturdy sprout branch, remaining is sprouted secateurs and falls.
The present invention has the advantage that relative to existing technology
1, one of the present invention utilizes black micropore water-permeability plastic film to carry out the dry method of forestation of Tectona grandis L. F. undercut, covers black above nursery stock
Micropore water-permeability plastic film, micropore water-permeability plastic film is unlike common ground film: it has micro-permeable structures, can seep water, ventilates, protect
Temperature, moisturizing, the effect of suppression weed growth, the precipitation of little rainfall can penetrate into the soil below mulch film by the micropore on mulch film
Earth, plays persistently insulation, moisture-keeping function, in full summer season, and the temperature below common ground film can rise to 60～70 °, can cause
Burn seedlings, and the temperature below water-permeability plastic film is much lower, only 43～44 °, the root system for plant creates more preferable growing environment.
2, one of the present invention utilizes black micropore water-permeability plastic film to carry out the dry method of forestation of Tectona grandis L. F. undercut, covers above nursery stock
Black micropore water-permeability plastic film, because of in soil under black plastic mulching raise cropFull nitrogen, organic matter, available potassium,Alkali-hydrolyzable nitrogenDeng nutrition
Index, the ratio raising having in various degree of covering common ground film, more preferable environment is created in the growth being more beneficial for plant.
3, one of the present invention utilizes black micropore water-permeability plastic film to carry out the dry method of forestation of Tectona grandis L. F. undercut, and the mulch film covered is long
10cm all little than kind of plant hole with width, beneficially rainwater penetrate in kind of plant hole, too increase kind of a permeability for plant hole soil.
4, one of the present invention utilizes mulch film to carry out the dry method of forestation of Tectona grandis L. F. undercut, and selectively the container seedling of footpath >=0.6cm enters
The dry afforestation of row undercut, the shoot of sprouting is sturdy, growth rapidly, 1 year raw trees averagely improve 20 than without cutting the dry nursery stock height of tree
～30cm, footpath, ground averagely improves 0.3～0.5cm, and survival rate improves 4～6%.
