Abstract
The invention discloses a flue-cured tobacco float breeding substrate. The flue-cured tobacco float breeding substrate is made of (A) core soil and thoroughly decomposed straws, wherein the volume percentage of the core soil and the thoroughly decomposed straws is 4-5:5-6, or (B) stones and thoroughly decomposed mushroom residues, wherein the volume percentage of the stones and the thoroughly decomposed mushroom residues is 6-8:2-4. The flue-cured tobacco float breeding substrate is mainly made of the core soil, the thoroughly decomposed straws, the washed stones and the thoroughly decomposed mushroom residues, all the materials are common materials in villages or waste produced after agricultural products are processed, are ecological and environmentally friendly, easy to obtain and low in production cost, and the thoroughly decomposed straws and the thoroughly decomposed mushroom residues contain rich organics, thereby providing enough nutrients needed by growth of tobacco seedlings. Obtaining of the raw materials and the preparation method of the substrate are simple, the operation technology is easy to master, the cost for float breeding is largely lowered, and meanwhile the straws and the mushroom residues are reasonably and effectively utilized.
Description
Technical field
The present invention relates to a kind of floating seedling cultivation substrate for flue-cured tobacco and preparation method thereof, belong to floating seedlings technical field.
Background technology
The effect of floating seedling cultivation substrate for flue-cured tobacco is: (1) provides mechanical support to cigarette strain and root system; (2) provide enough air to supply root system respiration; (3) provide growing of suitable moisture and nutrition supplying cigarette seedling.The contradiction of coordinating between water, gas is the theoretical foundation of selection and proportioning matrix.The existing floating seedling cultivation substrate for flue-cured tobacco of China be take the peat composed of rotten mosses as main body, the peat composed of rotten mosses is non-renewable resources, and environment is damaged, the exploitation limits of current China to peat composed of rotten mosses resource, this restriction has more obviously been increased and take the manufacture cost of the floating seedling cultivation substrate for flue-cured tobacco that the peat composed of rotten mosses is main component, directly increase tobacco seedling cost, affect the research and development of tobacco floating seed rearing.Due to tobacco floating seed rearing to the characteristic of matrix as: porosity, unit weight, content of organics, pH value, electrical conductivity, moisture all have specific (special) requirements, therefore how to find and both met the required matrix of tobacco floating seed rearing, cheap, the material that easily obtains ecological, environmental protective, has become the technical barrier that floating seedlings technical field faces again.
The patent No. is CN201010252560.8, the patent that name is called " a kind of floating seedling cultivation substrate for flue-cured tobacco and preparation method thereof " provides a kind of floating seedling cultivation substrate for flue-cured tobacco and preparation method thereof, adopt fermentation rice husk, fermented maize or broomcorn straw, high-temperature sterilization mellow soil, fine perlite as seedling medium, gather materials on the spot, ecological, environmental protective, cheap, saved seedling cost, but the emerging of tobacco, planting percent are not high.
Summary of the invention
The technical problem to be solved in the present invention is for above deficiency, provides a kind of medium characteristics good, draws materials easily, ecological, environmental protective, floating seedling cultivation substrate for flue-cured tobacco emerge, planting percent being high and preparation method thereof, has reduced tobacco leaf seedling-raising cost, reduced to produce and dropped into, increased economic benefit.
In order to solve above technical problem, the technical solution used in the present invention is as follows: a kind of floating seedling cultivation substrate for flue-cured tobacco, is selected from one of following combination:
A) heart position soil, the wheat straw that becomes thoroughly decomposed, each component percent by volume is: heart position soil: the wheat straw=4-5:5-6 becoming thoroughly decomposed;
