During concrete use
(1) levelling of the land
Build the place of booth, general is all that physical features is more smooth, open, but in mountain areas such as Guizhou, soil is just so unopen, and can reach the place building canopy requirement is the good soil in good farmland substantially, even if soil is not peaceful smooth, or area is inadequate, also can stone-laying bank, banket, guarantee that the plot built within the scope of canopy reaches smooth substantially, so just can guarantee that booth quality reaches requirement.Even now, also whether very flat in booth, and floating seedlings nutrition pond needs water base in pond to lift level, ensure that the degree of depth of water in a pond is basically identical, there will not be dark shallow on one side on one side, affect the uniformity and temperature of emerging, this just needs pond, one, a pond to lift level, not so, area is too wide looks for injustice, therefore, after booth is built up, need to carry out smooth and cleaning to place, the first step, to remove in canopy comparatively ratchel, dig up the low bank of earth between fields in soil or little mount, the soil dug out transfer is filled in the ditch of hypsography low-lying place or field soil, earth's surface in whole canopy is made to look substantially smooth, second step, by the weeds in canopy, the discarded object etc. stayed when building canopy cleans out outside nursery side stop, 3rd step, integrated planning is carried out to nursery pond.The principle of planning, one is utilize the useful space in booth as far as possible, avoid waste, two is in triplet or tetrad booth, (general slotting ground monomer canopy--there is not the problem of canopy inner column (stake of standing) in long 30 meters of x8 rice as far as possible the sidewalk that manual operation or personnel pass in and out to be located at booth inner column (stake of standing) position, as long as stay the operation sidewalk of 50 centimetres in the middle of in canopy), do not allow it be in nursery pond, pond is built in impact and nursery operates.
(2) grow seedling nutritional pond is built
1, the size in grow seedling nutritional pond is determined; Nursery pond construction principle to make full use of space in canopy, will be convenient to manually can carry out farming or mechanically actuated simultaneously.Determine that the size in grow seedling nutritional pond will be considered with lay-up operation sidewalk simultaneously.No matter triplet or tetrad booth, size is built in abundant planning and designing and after considering in conjunction with production practical situations in grow seedling nutritional pond, is clearly: the long 11 meters of x3.3 rice (net area) in single grow seedling nutritional pond.After this regulation, a triplet booth can build grow seedling nutritional pond, 18, grow seedling nutritional pond, and a tetrad booth can build 24, grow seedling nutritional pond.As long as insert ground monomer canopy then repair a sidewalk in centre, consider farming operability and nursery pond whether horizontal problem, block again, repair a horizontal sidewalk, form " cross " shape, as the length in grow seedling nutritional pond, not necessarily by the requirement of 11 meters of x3.3 rice, determine according to canopy length, but wide still by 3.3 meters of specifications.
2, operation sidewalk in booth is laid; Seedling raising greenhouse generally all offers inlet/outlet in the middle of canopy right overhead facade, and what have is also designed with between buffering, will be connected when operation sidewalk is built with passage of entering, and is convenient to personnel's turnover.Operation sidewalk is wide 50 centimetres, and length is consistent with canopy, but highly will lower than the ridge 5, grow seedling nutritional pond cm, avoid personnel by or farming operates time foul is brought into grow seedling nutritional pond, cause cigarette seedling pollution or catch an illness.Operation sidewalk can not be hardened into cement land for building in order to beautiful, lays with the little standard brick of general cement, and gap place earth or sand are filled, and guarantee that sidewalk is plain.If when in this movable standard brick canopy, facility has variation or needs to recover to plough, be easy to just remove.
Nursery pond makes organizational system on ground level as far as possible, not spoiled soil plow layer as far as possible.Grow seedling nutritional pond adopts the weedtree a tree, used in making timber for boats of long 4 meters of wide 0.1 meter of x of x high 0.1 meter (or high 0.05 meter of the wide 0.1 meter of x of 2 block lengths, 4 meters of x stacks) to build, it can be used as the ridge, limit in grow seedling nutritional pond, surround pond framework, wood a tree, used in making timber for boats length can be undertaken reducing, splicing by pond requirement, with screw, the junction book iron plate being equipped with hole is connected and fixed again, tenon also can be adopted to be fixedly connected with (slightly loaded down with trivial details), namely form the grow seedling nutritional Chi Chi ridge, Chi Geng exceeds 0.1 meter, ground in pond, exceeds operation about 0.05 meter, sidewalk.The outer eaves of Chi Geng is close to operation sidewalk, keeps net area 36.3 ㎡ in pond, can fill 171 floating plates, educate cigarette seedling 27360 strain.Calculate by planting percent 90%, left and right, 1.7 hectares, land for growing field crops (25 mu) can be transplanted, a tetrad booth 24 grow seedling nutritional ponds, by 90% planting percent, left and right, 40 hectares, land for growing field crops (600 mu) can be transplanted.
After grow seedling nutritional pond framework is built up, ground in further smooth pond, pulverizes the earth of the inside bulk with instruments such as hoes, pick out the hard impurities such as rubble, weeds, and strike off with wooden unit, then pat consolidation with instruments such as ocean shovels, like this, grow seedling nutritional pond just first one-step forming.Grow seedling nutritional pond does not adopt hardening of cement to build, otherwise can cause the heavy damage to original arable land, is difficult to the basic original appearance recovering original arable land, is the destruction to basic farmland protection, and the covert character of use changing arable land is a kind of behavior of appropriation of land.
(3) plastic film mulch in grow seedling nutritional pond
After nutrition pond is made, also need again to find level at the bottom of pond, then use the pesticide spray such as decis, phoxim once, the underground pests such as anti-mole cricket; Although carry out smooth at the bottom of pond, but still may occur the foreign material such as some hard stalk, iron wire, sands, can film be damaged, make seepage in film, therefore, must be rebasing with the fine earth that sieves, repave last layer worn-out agricultural film, bag with fertilizer, colour bar Polypropylence Sheet etc., then just plastic film mulch.Lay film we claim water bed film, the width of film is 4 meters, length 100 meters (being commonly referred to as 1 volume), and length can be reduced according to the length in nutrition pond, the farm-oriented mulch that its Thickness Ratio is general slightly thick (0.08 millimeter--8).To check (mainly checking with or without trachoma) water bed film before plastic film mulch, confirm water-tight.Paving water bed film time want unsettled membrane, can not draw on ground, so as not to film undermined, leak.
(4) water filling
After completing water bed film film, just start water filling in grow seedling nutritional pond, waterflooding requirement: the depth of water 6 ~ 8 centimetres, lower than nutrition pond ridge 2--4 centimetre, water quality requirement be clean, clean (in principle with running water, well water as well).After water filling is complete, nutrition pond surrounding water bed film is outwards overturn, is laid on the ridge, and unnecessary film is stuck in the ridge with the gap of operation sidewalk.When just having started water filling, do not inject too much water, first inject 3 cm, check whether after 1--2 to be placed days and leak, water-tight rear continuation notes 6--8 centimetre water, if leak, again changes film, in order to avoid again change film when finding below, not only increase workload and cost, be also unfavorable for operation.
(5) nutrient solution and copper sulphate is added
After water has been noted, nutrient solution and copper sulphate to be added with regard to `.Nutrient solution is a kind of Water soluble fertilizer being specifically designed to nursery, and solid shape is packaged by specification, and main component is nitrogen, phosphorus, potassium and some trace elements.During Ensure Liquid liquid, calculating amount of application to be carried out according to the size in nutrition pond, used Water soluble fertilizer is put into a plastic big basin, dissolved by clean water, the centre in grow seedling nutritional pond and two are poured into more respectively for point three parts, then basin has been scooped water in pond pouring repeatedly, guaranteed that in whole nutrition pond, nutrient solution fully mixes.Calculation of fertilization amount formula is: long (cm) × pond wide (cm) × depth of water (cm) × fertilising concentration (mg/kg) ÷ nutrient content (%) in fertilizing amount (kg)=pond; Or by often coiling consumption measuring and calculating.Can't stick with paste and disorderly use.While adding Water soluble fertilizer, also the copper sulphate dissolved is added.The program adding copper sulphate is the same with Water soluble fertilizer, also will carry out calculating according to the size in pond, could not go wrong.The object adding copper sulphate to suppress the root system of cigarette seedling to grow bottom floating Pan, long to depths, and not director Xiang Heng, also for being convenient to take out cigarette seedling after seedling, meanwhile, avoids because root system is long, produces damage when taking out cigarette seedling to floating plate.Copper sulphate usage amount is: 70 grams/pond (11 meters of x3.3 rice), and other substandard ponds calculate by 2 Ke/㎡.
(6) floating disc cultivating seedling is put into
After a few procedure completes above, just can start sabot nursery.Its flow process is as follows: outside booth, look for one piece of smooth place, whether lay plastic foil (or colour bar cloth) → staff seedling-cultivating tray that carries out disinfection before marching into the arena → check meets the requirements (as penetrating in bottom outlet no, coil whether distortion etc.) → check that whether matrix is (as moderate in moisture, whether lump, make mix whether even etc.) → sabot (all covering again after first filling 2/3) → check whether uniformity → with straight wood (bamboo) sheet strikes off and spreads a substratum matrix after revealing white hole rib → artificial seeding (or using seeder) → finish and cover, and strike off → send into nursery pond with wood (bamboo) sheet.
By above flow process, flue-cured tobacco seedling-cultivating nutrition pond has just been built up.
