Abstract
The invention discloses a flue-cured tobacco floating seedling matrix, a preparation method and the application thereof. Specifically, the matrix is made by mixing and sterilizing 10-65 parts of shale and 0-20 parts of organic fertilizer calculated by weight ratio. The preparation method thereof mainly comprises the following steps: (1) treatment of materials: the shale is crushed and sieved to cause the particle size of the shale to be 0.56mm for use; (2) mixing and disinfecting: the treated shale or the mixture that the treated shale and an organic fertilizer are fully mixed is sterilized and disinfected to obtain the flue-cured tobacco floating seedling matrix. The flue-cured tobacco floating seedling matrix and the preparation method thereof can solve the problems that the sources of the flue-cured tobacco floating seedling matrix materials are difficult, the production cost is high, and resource utilization contradicts the ecological environment protection. The flue-cured tobacco floating seedling matrix of the invention has the advantages that necessary nutrient components are provided for the growth of the flue-cured tobacco seedling, and the rate of emergence and the planting percent of the seedlings are improved.
Description
Technical field
The present invention relates to a kind of floating seedling cultivation substrate for flue-cured tobacco, relate in particular to a kind of efficiently, floating seedling cultivation substrate for flue-cured tobacco and its production and application cheaply.
Background technology
Floating seedlings is the main seedling raising manners that adopts on the cured tobacco production in recent years, and its seedling matrix material is a mixed-matrix, and prescription is complicated, the production cost height.
No. 200510048691.3 patent of Chinese patent provides a kind of with the floating seedlings culturing method of sand as host material.This method has overcome the deficiency that existing floating seedling cultivation substrate for flue-cured tobacco production cost height, permeability are poor, environment had pollution.But this method has the following disadvantages: mountain sand and river sand dry hole rate reach 8.5-10.1%, and fertilizer-preserving ability is poor, thereby have increased the difficulty of fertilising, and time-consuming; Merely do not contain organic matter and nutritive element with sand as the material of matrix, the seedling emergence rate of being cultivated is low, and planting percent is low.
Summary of the invention
The present invention has overcome above method deficiency, provides a kind of nutritive element abundant, easy to use, the emergence rate height, the planting percent height, the floating seedling cultivation substrate for flue-cured tobacco that production cost is low, relate in particular to a kind of efficiently, floating seedling cultivation substrate for flue-cured tobacco and its production and application cheaply.
For solving the problems of the technologies described above be, floating seedling cultivation substrate for flue-cured tobacco of the present invention calculates with weight ratio, and by 10～65 parts shale, 0～20 part fertilizer is formed.This method may further comprise the steps;
1) material is handled: sheep hepatolith shale is pulverized, and screening, making its particle diameter is that 0.5～6mm is stand-by;
2) mix sterilization: after shale or shale and fertilizer are fully mixed, handle through sterilizing.
Above-mentioned shale can be any one or more mixing in following: purple shale, black shale, culm, siliceous shale, irony shale, calcareous shale.
Above-mentioned sterilizing is handled, and comprise any processing or multiple mixed processing in following: high-temperature disinfection treatment, chemical agent are disinfected, uviol lamp is disinfected.
Above-mentioned floating seedling cultivation substrate for flue-cured tobacco is as the application of floating seedling cultivation of fire-cured tobacco.Its using method floating seedling cultivation substrate for flue-cured tobacco occupation mode is routinely used.
Innovative point of the present invention and good effect
1, the shale main chemical compositions is organic 0.096～10.098%, full nitrogen: 0.018～0.032%, full potassium: 1.0023～1.0467%, full phosphorus: 0.05～0.07%, hydrolyzable nitrogen: 11.11～13.11mg/kg, hydrolysis phosphorus: 6.6～7.2mg/kg, effective potassium: 74.2～83.2mg/kg, chlorion: 5.68～5.83mg/kg, effective calcium 0.37～0.42%, effective magnesium: 167.0～189.0mg/kg, effective copper: 0.229～0.329mg/kg, effective iron: 0.064～0.078mg/kg.Become active well plant nutrient after nutritive element slowly-releasing in the shale comes out, can be the flue-cured tobacco seedling-cultivating growth necessary middle micro-nutrient composition is provided.
2, because shale has certain adsorption capacity, can adsorb nutritive element when contacting with fertilizer, form " warehouse " of plant nutrient and physiological activator, thereby effectively slow down the speed that nutritive element discharges and decomposes, reach the raising fertilizer efficiency, increase survival rate of seedling, reduce the multiple effect of polluting.
3, this floating seedling cultivation substrate for flue-cured tobacco is because efficient, low-cost; can large-scale application in cured tobacco production; this has opened up new technological approaches for the agricultural use of shale, thereby China is improved the level of resources utilization and protects non-renewable resources to do the contribution that makes new advances.
