Abstract
The invention discloses a flue-cured tobacco float breeding matrix and a preparation method of the flue-cured tobacco float breeding matrix. The matrix comprises main components of fermented rice husks or/and dried corn straws and broomcorn straws and a certain amount of high temperature disinfected mellow soil or deshydratees and puffed pearl. The preparation method mainly comprises the following steps of: performing biomass fermentation, configuring the matrix according to components and performing steam sterilization. The flue-cured tobacco float breeding matrix has the advantages that the fermentation rice husks, the corn straws and the broomcorn straws in the matrix are used as the main components and are waste produced by processing the conventional crops; the substances are easily available and are low in production cost; moreover, the fermented rice husks, the dried corn straws and the broomcorn straws contain rich organic substances; and a demand of tobacco seedlings for nutritious components during growth process can be well met.
Description
Technical field
The present invention relates to floating seedling cultivation substrate for flue-cured tobacco and preparation method thereof.
Background technology
The existing floating seedling cultivation substrate for flue-cured tobacco of China still be take the peat composed of rotten mosses as main body, the peat composed of rotten mosses is Nonrenewable resources, a large amount of use caused the wasting of resources, therefore, at present China by the exploitation restriction of peat composed of rotten mosses resource in the reasonable scope, this restriction, by obviously having increased existing manufacture cost of take the floating seedling cultivation substrate for flue-cured tobacco that the peat composed of rotten mosses is main component, obviously improves the price of floating seedling cultivation substrate for flue-cured tobacco, this also will 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, organic content, pH value, specific conductivity, moisture content all have particular requirement, therefore how to find a kind of required matrix of tobacco floating seed rearing that both met, again cheap, easily obtain material and become the technical barrier that prior art field faces.
Summary of the invention
The present invention is for avoiding the existing weak point of above-mentioned prior art, provides a kind of medium characteristics good, levitating seed-cultivating interstitial substance that is applicable to China Ge Yan district easily obtaining and preparation method thereof.
It is to adopt following technical scheme that the present invention deals with problems:
A floating seedling cultivation substrate for flue-cured tobacco, is selected from one of following combination:
A) fermentation rice husk, high-temperature sterilization mellow soil, fine perlite, each component volume percent is: fermentation rice husk: high-temperature sterilization mellow soil: fine perlite=6:2-2.5:1.5-2;
B) fermentation rice husk, slag ash, fine perlite, each component volume percent is: fermentation rice husk: slag ash: fine perlite=6:2-2.5:1.5-2;
C) fermented maize or broomcorn straw: fermentation rice husk: fine perlite, each component volume percent is: fermented maize stalk: fermentation rice husk: fine perlite=3-4:5-6:1;
D) fermented maize stalk: fermentation rice husk: high-temperature sterilization mellow soil, each component volume percent is: fermented maize stalk: fermentation rice husk: high-temperature sterilization mellow soil=3-4:5-6:1.
Floating seedling cultivation substrate for flue-cured tobacco of the present invention, its characteristic is: described matrix pH value is 5.5-6.0; Particle diameter is 2-5mm.
Floating seedling cultivation substrate for flue-cured tobacco of the present invention, its characteristic also has: the porosity of described matrix is 68-75%, and unit weight scope is 0.5-0.8g/cm3, and specific conductivity is 14.5-23.0.
The preparation method of floating seedling cultivation substrate for flue-cured tobacco of the present invention, comprises the following steps:
1), fermentation of biomass preparation: biological straw starter+particle diameter is crushed to the rice husk of 2-5mm or withered maize straw or withered broomcorn straw+water and mixes by weight the ratio of 1:400:80,55-60 days ferments at 55-60 ℃ of temperature, make rice husk surface by Huang turn ash or maize straw, broomcorn straw surface grows white hypha, gives off a peculiar smell, and dries rear color Dark grey.
2), matrix configuration: above-mentioned fermentation of biomass and slag ash, fine perlite, high-temperature sterilization mellow soil are configured by A claimed in claim 1, B, C, D, four kinds of combinations, mix, then under closed environment, with steam sterilizing 8-10h, obtain matrix.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1) in floating seedling cultivation substrate for flue-cured tobacco of the present invention, use fermentation rice husk, maize straw, broomcorn straw as main ingredient, these materials are all the common rear waste of farm crop processing, not only easily obtain, production cost is low, and fermentation rice husk, maize straw, broomcorn straw contain abundant organic matter, can better meet 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 matrix is at 68-75%, and unit weight scope is at 0.5-0.8g/cm3, and specific conductivity is 14.5-23.0, and these characteristics are well positioned to meet tobacco seedling growth environment, guarantees growing up strong and sturdy of cigarette seedling.
3) base starting material of the present invention obtain and compound method method simple, operative technique is easy to grasp; Can not only reduce significantly floating seedlings cost, and make rice husk, maize straw, broomcorn straw obtain rationally effectively utilizing.
Embodiment
Below in conjunction with example, invention is further described, but embodiment is not limitation of the present invention:
Since 2007, applicant carried out the research work of levitating seed-cultivating interstitial substance substitutability in Bozhou, and the research through triennium, filters out substrate formula of the present invention.Specific examples is as follows:
Extend trial is arranged in Qiaocheng District, Bozhou Zhang Ji, and test period is designed in by the end of December, 2008-2009 on April 10,, on August 15th, 2009-by the end of October.
1), fermentation of biomass preparation: biological straw starter+particle diameter is crushed to the rice husk of 2-5mm or withered maize straw or withered broomcorn straw+water by weight 1: the ratio of 400:80 mixes, 55-60 days ferments at 55-60 ℃ of temperature, make rice husk surface by Huang turn ash or maize straw, broomcorn straw surface grows white hypha, gives off a peculiar smell, and dries rear color Dark grey.
2), matrix configuration: above-mentioned fermentation of biomass and slag ash, fine perlite, high-temperature sterilization mellow soil are configured by the various combinations of table 1, mix, then under closed environment, use steam sterilizing 8-10h, standby.
Slag ash in the present invention refers to the material staying after coal briquette or loose coal combustion.
High-temperature sterilization mellow soil refers to the mellow soil of farming operation layer soil after steam high-temperature sterilization 8-10h.
In his-and-hers watches 1, on various heterogeneity composite substrates, carry out tobacco seedling, before growing seedlings, detect unit weight scope, pH value, specific conductivity, the porosity of medium of seedling bed, grow seedlings and detect matrix water suction situation in latter 24 hours, in 40 days, detect the stromal surface situation detected result of saltouing as shown in table 2:
The cigarette seedling of cultivating in above-mentioned matrix emerge and growing state is shown in Table 3:
