Description
Technical field
The present invention relates to a kind of plant cultivation method, particularly the light base material mesh bag seedling-cultivating method of a kind of Anlnus nepalensis.
Background technology
Anlnus nepalensis (Alnus nepalensis D.Don), has another name called alnus nepalensis (Chinese tree systematics), alnus nepalensis (Chinese Plants will), and wax gourd tree (Yunnan), is Betulaceae Alder megaphanerophyte, high approximately 18 meters, 1 meter of the diameter of a cross-section of a tree trunk 1.3 meters above the ground; Anlnus nepalensis material is thin, and texture is straight, and wood grain is clear, for furniture processed, vessel, as made tea packaging box, odorlessness; Bark is used as medicine containing tannin can anti-inflammation hemostasia; Root tool rhizobium, parasitic azotobacteria, leaf is high-quality green manure, can improve soil ，Wei mountain region getting fat, is applicable to Forest tree seed storage; Anti-runoff ability and the anti-soil erosion ability of Anlnus nepalensis woods group are stronger, can be used as the Major Tree Species Planted of soil and water conservation forest, water conservation forest.Early wax gourd growth is rapid, wide adaptability, and after felling, sprouts of stump power is strong, has good natural regeneration and sprout tillers updating ability, available green barren hill seeds.Anlnus nepalensis can be handed over multiple coniferous species is mixed, for changing pure forest structure, increases also field amount of nutrient, promotes the growth of the purpose species of trees, reduces damage by disease and insect and strengthen various barrier propterties playing an important role, and is the fine tree species of the multi-functional woodss such as the construction ecological forest, timber forest.
Yet, there is following major technique shortcoming in traditional Anlnus nepalensis plastic nutritional bag seedling method:
1, seedling root is wound around mutually, and nest root phenomenon is serious, and root system is undeveloped, seedling quality is not high, and seedling-slowing stage is long, and resistance is poor;
2, bagwork efficiency is low, and the speed of growing seedlings is slow;
3, Heavy Weight, cost of transportation is high;
4, stripping bag plantation, contaminated environment.Secondly, the loose easy damaged root system of native ball, survival rate is on the low side;
5, substrate preparation is unreasonable, and Container Type is single, and extensive management is not focused on the quality of seed and the problems such as application of advanced seedling growing process.
Summary of the invention
The deficiency existing for solving above-mentioned prior art, the present invention proposes the light base material mesh bag seedling-cultivating method of a kind of Anlnus nepalensis, has air root relief, and root system development is good; Lightweight, packing, convenient transportation, improve the advantages such as afforestation effect; Band container for plant growth and matrix are transplanted, and survival rate is high, and growth of young plantations speed is fast; Container production mechanization completes, the advantages such as speed is fast, saving labour.
For achieving the above object, technical scheme of the present invention is:
A light base material mesh bag seedling-cultivating method, comprising:
Step 1, base starting material are selected and preparation
Select sawdust, peat composed of rotten mosses soil, chimney soot, edible fungus stick, perlite as base starting material, sawdust be placed in and outdoorly naturally stacked 2 years, become thoroughly decomposed after fermentation, with peat composed of rotten mosses soil, chimney soot, bacterium rod, perlite through airing, pulverizing rear 0.3-0.4mm mesh
After according to fermentation sawdust: peat composed of rotten mosses soil: chimney soot: bacterium rod: the volume ratio of perlite=4:2:2:1:1 is prepared, and with matrix agitator, matrix is stirred;
Step 2, mesh bag are produced and are processed
According to institute's aglucon matter, utilizing mesh bag production machine to produce diameter is 4.5 centimetres of base material mesh bags, and the pond that base material mesh bag is put into 5 ‰ potassium permanganate is soaked after 12 hours and picked up, and with cutting machine, mesh bag is cut into the sack boxing for later use of length equalization;
Step 3, mesh bag seedling are cultivated
1. sowing and seedling management
Sow front seedbed and first water permeablely, seed is broadcasted sowing uniformly on seedbed, after broadcasting, spraying is watered immediately, then builds plastic film hut with insulation, it on the shading screen covering of light transmittance 70%; Sowing Anlnus nepalensis seed after 7 days starts to germinate; When seedling is unearthed in a large number, control water in good time, take a small amount of spraying sprinkling method repeatedly; Within after bud seedling all sprouts every 10 days, spray Yi Ci natural pond liquid, spray carbendazim liquid, to prevent the generation of disease simultaneously; Weeding is accomplished except morning, except principle little, that eliminate;
2. transplant
When growing 2-3 sheet sheet true leaf, Anlnus nepalensis seedling transplants mean height 1.5cm; Before transplanting, first sack is watered permeablely, treat that matrix reaches 90% moisture content and bud seedling can be moved in bag;
Bud seedling will first drench after sufficient water lifting again; During lifting, must be noted that multi-band soil and the integrality that keeps root system as far as possible, during transplanting, with left hand, hold gently a strain seedling, the right hand is inserted an aperture with small wood in bag central authorities, then seedlings root is completely vertically put into cave, the right hand, has been transplanted and has been watered in time afterwards the matrix compacting of cave one side with wooden stick; With bamboo chip, build 50～60cm plastic canopy and highly build the shading shed of light transmittance 60% with insulation insulation ，Ju ground 1.5～1.8m.
3. the management after transplanting
In one week after transplanting, pay special attention to strengthen the management to moisture, must guard against and allow seedling occur that lack of water causes death of seedling; Accomplish 2d water 1 time permeable, in case of special high temperature, dry weather water every day 1 time permeable; Bag seedling is carried out after surviving and is watered, weeding, fertilising work; Weeding is accomplished except early, except little as far as possible, avoids weeds to affect seedling growth, forbids to use weed killer herbicide to carry out weeding; Topdress and can carry out with watering to combine, with 15～20d, spray 1 natural pond liquid and impel growth of seedling; Topdress and should repeatedly carry out on a small quantity; Before outplanting, control gradually water control fertilizer, shading screen is removed by stages, impel the further lignification of nursery stock.
Described step 1 is used acetic acid neutralisation treatment in matrix stirs, and matrix pH value is adjusted into 5.5-7.
Mesh bag length in described step 2 after cutting is 8CM.
Described step 3 1. sow with seedling management in, prevent that the concrete grammar that disease occurs from being: with 50% carbendazim wettable powder, spray once week about, disease sprays medicine 1 time every day as occurred, every day 2 times when serious, respectively 1 time sooner or later.
With respect to prior art, beneficial effect of the present invention is: the present invention adopts light base material mesh bag to grow seedlings, air root relief, and root system development is good; Lightweight, packing, convenient transportation, afforestation effect is high, and base material mesh bag can decompose voluntarily, non-environmental-pollution; Have band container for plant growth and matrix and transplant, survival rate is high, and growth of young plantations speed is fast; Container production mechanization completes, the advantages such as speed is fast, saving labour.
