Abstract
The invention belongs to the technical field of raising seedlings of flue-cured tobacco, and in particular relates to a method for raising seedlings of flue-cured tobacco by moistening. The method comprises the following steps: (1) preparing a site, a seedling tray and a rectangular water plate; (2) sowing; (3) managing in a seedling stage, wherein, the rectangular water plate is maintained to befilled with water before a cross-shaped stage of the tobacco seedlings, and the rectangular water plate is not filled with water while matrixes are maintained to be moistened after the cross-shaped stage of the tobacco seedlings; and (4) preparing for transplantation. By adopting the method for raising the flue-cured tobacco seedlings, less water is needed, cost of seedling-raising materials is low, the tobacco seedlings can be cultured stereoscopically, and the root systems of the tobacco seedlings are well-developed.
Description
Technical field
The invention belongs to the flue-cured tobacco seedling-cultivating technical field, be specifically related to the moistening method of growing seedlings of a kind of flue-cured tobacco.
Background technology
The flue-cured tobacco seedling-cultivating of China experienced flat furrow broadcast sowing grow seedlings, flat furrow nutritional bag and three developing stage of floating seedlings.What widely adopt at present is the floating seedlings mode, its main device that adopts is the floating type seedling-cultivating tray that polystyrene foam is made, concrete mode is: set up nursery pond in booth, place nutrient solution and water in the pond, cigarette seed mixed culture medium is planted on the hole of growing seedlings of floating type seedling-cultivating tray, after the cigarette seedling is bred, the floating type seedling-cultivating tray that to give birth to into seedling is distributed to the plantation place, after transplant finishing again with floating type seedling-cultivating tray wash clean, withdrawal concentrates on the keeping of tobacco purchasing point, finally is recovered to nursery again.
Though the mode that floating type is grown seedlings can satisfy the demand of flue-cured tobacco seedling-cultivating to a certain extent, but it still exists following problem in the actual use: 1, the floating type seedling-cultivating tray is owing to need be placed in the nursery pond, and nursery pond need be arranged on the level land, owing to can not adopt the mode of solid growth, the amount of growing seedlings in its unit space is less; 2, owing to need to place a large amount of nutrient solutions and water in the nursery pond, for the water-deficient area, the cost that floating type is grown seedlings is higher; 3, the aquatic environment that floating type is grown seedlings, than being easier to cause disease, emergence rate is lower, and because root system is in the water environment for a long time, it is undeveloped causing into shoot root; 4, the seedling dish that floating type is educated adopts polystyrene foam to make, and its intensity is lower, is very easy to damage in the process that companion cigarette seedling is transported together, causes seedling cost higher.
Summary of the invention
But the technical problem to be solved in the present invention provides less, the flourishing moistening seedling-cultivating method of flue-cured tobacco of stereo cultivation cigarette seedling and cigarette shoot root system of growing seedlings that the cost of material is low of a kind of demand to water.
In order to solve the problems of the technologies described above, the invention provides the moistening seedling-cultivating method of a kind of flue-cured tobacco, include following steps:
1) plantation is prepared, build plastic tunnel, and the place in the smooth plastic tunnel, the plastics seedling dish that ground on the scene is settled the rectangle water pond and cooperated with the rectangle water pond, the rectangle water pond degree of depth is 3～5cm, and it is 2～6cm that plastics seedling dish is provided with hole, the hole aperture area of placing matrix and cigarette kind
2, the degree of depth is 1～3cm, and the bottom, hole is provided with permeable hole, and plastics seedling tray bottom is filled up matrix apart from rectangle water pond 1～2cm in the hole;
2) sowing, in the first ten-day period of the March in every year, in the matrix in hole, each hole is settled 2 with the sowing of cigarette kind, implants the dilution nutrient solution of 1:1000 in the rectangle water pond, and the dilution nutrient solution degree of depth remains on 1～2cm;
3) seedling management, keeping the temperature in the booth is 20～25 ℃, and humidity is 50%～70%,, guarantees not cut off the water supply in the rectangle water pond before the phase at the grand cross of cigarette seedling, and at the grand cross after date of cigarette seedling, the rectangle water pond is cut off the water supply, and guarantees that by watering or water spray matrix is moistening;
4) transplant to prepare, in transplanting preceding 3 days, the dilution nutrient solution of 1:1000 is added the rectangle water pond, the degree of depth is that the degree of depth is 1～3cm.
Wherein, matrix is planted the commodity matrix that industry is generally used for the cigarette seed, and its main component is peat, the peat composed of rotten mosses, vermiculite and fine perlite.The dilution nutrient solution of 1:1000 is the liquid that obtains behind commodity nutrient solution and the ratio mixed diluting of water according to 1:1000, and its main nutrient composition is nitrogen, phosphorus, potassium and various little fertilizer.
As preferred version, in order to realize three-dimensional seedling raising, improve the amount of growing seedlings in the unit space, also be provided with the support that can lay the rectangle water pond on the place in the step (1), described support is 1～3 layer, layer is apart from 0.8～1m.
As preferred version, in order to save matrix, simultaneously for the ease of laying matrix, the matrix in the step (1) flushes with the opening in hole, and a need be placed on Miao Panshang with matrix like this, gets final product matrix is floating then.
As preferred version, for the grand cross at the cigarette seedling in the step (3) that guarantees cigarette seedling support place need applied fertilizer before the phase 1～3 time.
Though adopt moistening seedling-cultivating method of the present invention to be difficult for forming the cigarette seedling that height differs, as preferred version, reach neat and consistent in order to guarantee the cigarette seedling, the grand cross after date at the cigarette seedling in the step (3) carries out 1 leaf-cutting.
Adopt the moistening seedling-cultivating method of flue-cured tobacco of technique scheme to have following advantage, 1, owing to adopted the rectangle water pond to replace traditional nursery pond, the rectangle water pond can be placed on the support body, can realize three-dimensional seedling raising, improves the amount of growing seedlings in the unit space; 2, because the rectangle water pond is much smaller than nursery pond, plastics seedling dish is placed in the rectangle water pond by feet, can moisteningly grow seedlings, and is therefore less to the demand of water; 3, because at the grand cross after date of cigarette seedling, the rectangle water pond is cut off the water supply, guarantee that by watering or water spray matrix is moistening, root system needn't be immersed in the water for a long time, so well developed root system and cigarette seedling are difficult for sick; 4, owing to adopt plastics seedling dish to replace polystyrene foam seedling dish, it is not fragile.
Last table is that the inventor is at the different times of breeding experiment, floating seedlings culturing method and moistening seedling-cultivating method are randomly drawed 100 strain cigarette seedlings respectively obtain experimental data, can clearly find out from cigarette seedling test situation in seedling stage, adopt not only emergence rate height of moistening seedling-cultivating method of the present invention, and root system development is good, has excellent popularization and is worth.
