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 is for root system respiration；(3) suitable moisture and the growth promoter of nutrition supplying tobacco seedlings are provided.Coordinate the contradiction between water, gas
It is to select and the theoretical basis of proportioning substrate.The existing floating seedling cultivation substrate for flue-cured tobacco of China is based on the peat composed of rotten mosses, and the peat composed of rotten mosses is can not be again
Production-goods source, and also environment is damaged, the exploitation of peat composed of rotten mosses resource is carried out and is limited by current China, and this restriction becomes apparent from increasing
The production preparation cost of the high floating seedling cultivation substrate for flue-cured tobacco with the peat composed of rotten mosses as main component, directly increase tobacco seedling cost, shadow
Ring the research and development of tobacco floating seed rearing.Due to tobacco floating seed rearing to the characteristic of substrate such as: porosity, unit weight, Organic substance
Content, pH value, electrical conductivity, moisture all have particular/special requirement, the most how to find the base both met needed for tobacco floating seed rearing
Matter, the material of acquisition ecological, environmental protective the most cheap, easy, it has also become the technical barrier that floating seedlings technical field is faced.
Patent No. CN201010252560.8, entitled " a kind of's floating seedling cultivation substrate for flue-cured tobacco and preparation method thereof " is special
Profit provides a kind of floating seedling cultivation substrate for flue-cured tobacco and preparation method thereof, uses fermentation rice husk, fermented maize or broomcorn straw, high temperature
Sterilization mellow soil, fine perlite, as seedling medium, are gathered materials on the spot, and ecological, environmental protective is cheap, has saved seedling cost, but
It is that the emerging of Nicotiana tabacum L., planting percent are the highest.
Summary of the invention
The technical problem to be solved in the present invention is for above not enough, it is provided that a kind of medium characteristics is good, draws materials easily, ecological
Environmental protection, emerges, floating seedling cultivation substrate for flue-cured tobacco that planting percent is high and preparation method thereof, reduces tobacco leaf seedling-raising cost, decreases life
Produce and put into, add 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, choosing
From one of following combination:
A) wheat straw that heart position is native, become thoroughly decomposed, each volume components percentage ratio is: heart position soil: the wheat straw=4-5:5-6 become thoroughly decomposed；
B) stone, the mushroom leftover bits and pieces that becomes thoroughly decomposed, each volume components ratio is: stone: the mushroom leftover bits and pieces=6-8:2-4 become thoroughly decomposed.
Preferably, a kind of floating seedling cultivation substrate for flue-cured tobacco, selected from one of following combination:
A) wheat straw that heart position is native, become thoroughly decomposed, each volume components percentage ratio is: heart position soil: the wheat straw=5:5 become thoroughly decomposed；
B) stone, the mushroom leftover bits and pieces that becomes thoroughly decomposed, each volume components ratio is: stone: the mushroom leftover bits and pieces=8:2 become thoroughly decomposed.
The floating seedling cultivation substrate for flue-cured tobacco of the present invention, its characteristic is: described substrate pH value is 5.8-7.1, and particle diameter is 0.5-
2.5mm。
The floating seedling cultivation substrate for flue-cured tobacco of the present invention, its characteristic also has: described matrix porosity is 70-80%；Unit weight scope is
0.19-0.44g/cm3, electrical conductivity is 2.0-2.6 μ s/cm.
The preparation method of the floating seedling cultivation substrate for flue-cured tobacco of the present invention, comprises the following steps:
1) preparation of each component:
The wheat straw become thoroughly decomposed or the preparation of mushroom leftover bits and pieces: the wheat straw of the particle diameter≤2.5mm after pulverizing or mushroom leftover bits and pieces
Piling up, thickness is not higher than 0.70m, and watering is 30% to water content, tightly covers with plastic sheeting or wheat bran mud, ferments to 60-70
DEG C keep 55-60 days；
The preparation of heart position soil: fetch earth after scalping the thick mellow soil of earth's surface 20cm, clap broken sieve make particle diameter 2.5mm after stand-by；
The preparation of stone: particle diameter is accounted for less than 2.5mm the stone washing of 90% volume.
2) substrate configuration: above-mentioned each raw material is carried out proportioning, mix homogeneously according to two kinds of combinations, fumigates beauteously with this, spray
Spill octicin solution sterilization, obtain substrate.
The present invention takes above technical scheme, has the advantage that
1) wheat straw make motive position soil in the floating seedling cultivation substrate for flue-cured tobacco of the present invention, becoming thoroughly decomposed, the mushroom washed stone, become thoroughly decomposed
Leftover bits and pieces as main component, these materials be all rural area Common materials or crops processing after garbage, not only ecological, environmental protective,
Be readily available, production cost low, and containing abundant organic matter in the wheat straw become thoroughly decomposed and the mushroom leftover bits and pieces that becomes thoroughly decomposed, it is possible to full
Foot tobacco seedling growth desired nutritional composition.
2) levitating seed-cultivating interstitial substance of the present invention is made by each component proportion, and the porosity of its substrate is at 70-80%, unit weight model
Being trapped among 0.19-0.44g/cm3, electrical conductivity is 2.0-2.6 μ s/cm, and these characteristics disclosure satisfy that tobacco seedling growth environment, it is ensured that tobacco seedlings
Normal growth.
3) base starting material of the present invention obtains and compound method is simple, and operating technology is prone to grasp；Significantly reduce
Floating seedlings cost, makes wheat straw, mushroom leftover bits and pieces obtain the most effective utilization simultaneously.
4) emergence rate of both matrix treatments is all better than commodity substrate.
