Description
Technical field: the invention belongs to the floating seedling cultivation of fire-cured tobacco technical field.
Background technology: floating seedling cultivation of fire-cured tobacco is the present advanced person's who extensively adopts in the world a seedling growing process, but need a large amount of matrix material in the floating seedling cultivation of fire-cured tobacco technology as cultivating soil, since in the flue-cured tobacco seedling-cultivating to the porosity of medium characteristics, permeability, unit weight, the content of organic matter, pH value, humic acid, electrical conductivity, water content, effectively iron ion and effectively manganese ion content, specific (special) requirements is all arranged, so at present host material will lean against growth forest or the land for building in the virgin forest for many years and gets careless carbon and be equipped with expanded perlite then, batch mixes such as expanded vermiculite form, nowadays consider the influence of environmental protection and water and soil loss, progressively limited taking of careless carbon, make that the source of goods of matrix is in short supply, price is high, every cubic metre price is generally 600～700 yuans, has increased the cost of floating seedlings undoubtedly greatly; Even, present for example expanded perlite, expanded vermiculite etc. of some compositions in the matrix material that uses, because of its chemical property is not degraded for a long time, long-term use meeting causes certain pollution to the field of planting flue-cured tobacco.How can seek a kind of cheaply, obtain easily, and meet the matrix of educating cigarette seedling characteristic and become one and be stranded the technical barrier of scratching this technical field technical staff.
Purpose of the present invention, provide a kind of low price that has in order to overcome the weak point that exists in the above-mentioned existing floating seedling cultivation of fire-cured tobacco technology just, good, the easy acquisition of permeability, ten minutes meet the floating seedling cultivation of fire-cured tobacco sand cultivation technique that tobacco floating is educated technical characteristic.
The objective of the invention is to realize by following technical solution.
Be that matrix is placed in the hole of seedling-cultivating tray, allow whole seedling-cultivating tray swim on the nutrient solution, nutrient solution provides cultivation nutrient by the cigarette seedling of bottom outlet in being planted in the seedling-cultivating tray hole of seedling-cultivating tray; Host material is husky; From being seeded into the cigarette seedling and entering in " grand cross phase " 30～35 days, the addition of nutrient solution makes seedling-cultivating tray produce floating being as the criterion for being unlikely to; In " the grand cross phase " of cigarette seedling, the interpolation nutrient solution is dark 8～12cm to the pond, seedling-cultivating tray is produced be floated to transplanting.
Because husky is that the husky bottom outlet that can carry over seedling-cultivating tray in flotation process sinks to nursery pond as the matter of utmost importance of matrix in the floating seedlings technology, cause the loss of matrix, therefore, the present invention will be seeded into the cigarette seedling enter " grand cross phase " (be one or two true leaves of cigarette seedling intersect be crosswise) with three or four true leaves during this time be about in 30～35 days, adopt nutrient solution that seedling-cultivating tray is only produced infiltration keeping effect and is unlikely to make the seedling-cultivating tray generation floating, can be under the husky situation that in the seedling-cultivating tray hole, does not produce drift motion as matrix because of flow action does not run off along the seedling-cultivating tray bottom outlet, and nutrient solution can provide nutrition to matrix and cigarette seedling by the seedling-cultivating tray bottom outlet; And the cigarette seedling enters " grand cross phase " and has progressively produced many root systems by growth, these root systems spread to whole matrix part, forming the effect of grabbing of a kind of pocket grabs matrix firmly and catches, therefore, after " grand cross phase ", the addition of nutrient solution should increase, and makes seedling-cultivating tray enter drift epoch, and promptly from " little cross phase " to " grand cross phase " husky matrix during this can't make husky the generation run off because of the package action of cigarette shoot root system.Promptly " the grand cross phase " of cigarette seedling to 30～35 days that transplant in, the addition of nutrient solution should be dark 8～12cm to the pond, it is floating that seedling-cultivating tray is produced, and becomes until the cigarette seedling and just can transplant the land for growing field crops strong sprout.
The present invention compared with prior art; have with low cost; joint medicine resource, the good advantage of cigarette seedling quality that makes things convenient for management, saving of labor, province's fertilizer, cultivates; husky every cubic metre price is generally 40～50 yuans; reduce about 15 times than careless carbon matrix cost price; husky harmless and can improve native Reel to the farmland, help protecting environment and maintenance ecology.
Further set forth content of the present invention below in conjunction with drawings and Examples.
Fig. 1 is the schematic diagram of growing seedlings of the present invention;
Fig. 2 is a floating seedlings schematic diagram of the present invention.
Embodiment one: the present invention there is no specific (special) requirements as the sand of matrix 1 material, and promptly common sand material gets final product, and seedling-cultivating tray 2 is selected 200 hole polystyrene foamed plastics lattice seedling-cultivating trays, specification: 66.5cm * 34cm * 5.5cm for use.Every dish weight 190～220 grams.No matter husky body material is mountain sand or river sand, and what emphasis was considered is ventilation dish water-based energy, water imbibition and water binding capacity, unit weight, hole ratio, adsorptivity, physical and chemical stability, have no side effect, particle size, pollution-free, no earth, free from admixture.Availablely before using execute fumigation sterilization beauteously, make husky body keep certain gentle during use, can be agglomerating to hold, scatter naturally for good in the back of loosing one's grip; Medium in tray after taking matrix filled up the hole 3 of seedling-cultivating tray, will keep 3～4 centimetres stromal thickness more than the card, matrix dish flush end overhead about 10 centimetres, is carried out pier three times, and just matrix reaches certain packing in dish, then card is wipeed off.Extrude 2～3 millimeters shallow nest at center, matrix hole with finger or pressure orifice plate during sowing, broadcast 1～2 tobacco seed, spread the dry matrices 1 of one millimeter of one deck then thereon equably again, kept about 7 days adding clean water in the nursery pond, amount of water only produces immersional wetting to seedling-cultivating tray and unlikelyly makes it floating, the water liquid height is between 0.5～1.5cm, water changes nutrient solution 5 into after 7 days, every about 7 days, replenish one time of nutrition liquid 5, addition still remains between 0.5～1.5cm, and unlikely that seedling-cultivating tray is produced is floating.Cigarette seedling 6 enters " grand cross phase " (be one or two true leaves of cigarette seedling intersect with three or four true leaves be crosswise) from being seeded into, time is about 30～35 days during this, the nutrient solution that adopts only produces the infiltration keeping to seedling-cultivating tray and acts on, unlikely that seedling-cultivating tray is produced is floating, and whole seedling-cultivating tray all should be stabilized in a place and not produce floating." the grand cross phase " of cigarette seedling 6 back to 30～35 days that transplant in, the addition of nutrient solution increases, it is floating that seedling-cultivating tray is produced, addition this moment of nutrient solution 5 should be to the pond dark 8～12cm, be enough to make seedling-cultivating tray to produce floating effect.And at this moment because the root system 7 of cigarette seedling prosperity has tightly wrapped the husky body material of matrix 1, husky body material just can not run off along the bottom outlet 4 of seedling-cultivating tray 2 yet in floating.
