Abstract
A tobacco coated seed with disease-resistant cladding shell comprises a seed body, and is characterized in that the seed body is coated with a paecilomyceslilacinus ZY-19-2 antagonistic layer and a chitooligosaccharides inducing layer. The tobacco coated seed has the main advantages that the process is convenient, the industrial production is suitable, and the raw materials used by the cladding shell are pollution-free and friendly to the environment, and non-residue. In the utility model, as the antagonistic layer of the cladding shell of the seed contains paecilomyceslilacinus ZY-19-2 spores, the coated seed can effectively control the tobacco fungi disease. The inducing layer in the cladding shell contains chitooligosaccharides which is a soft pesticide, and has better bacteriostatic activity on fungi and bacteria, and can induce the chitinase activity in plants to be increased, and is absolutely safe to people and livestock as well as the environment, and the chitooligosaccharides can induce the paecilomyceslilacinus ZY-19-2 to generate chitinase so as to prevent tobacco fungi disease, thus achieving the purpose of improving the tobacco yield finally.
Description
Technical field
The utility model relates to a kind of tobacco seed packaging technique, particularly a kind of tobacco seed-coating seed that has disease-resistant encasement, this capsuled seed can effectively be controlled the tobacco fungal disease and can induce the fungal disease that produces in soil or the culture matrix in chitinase microorganism antagonism soil or the culture matrix.
Background technology
China develops the tobacco seed seed coating medicine since late 1980s, to the beginning of the nineties this technology be mature on the whole, the each province develops in the cigarette district polytype seed coating medicine and carries out tobacco seed processing, and the tobacco seed-coating pelleted seed begins to apply in leaf tobacco production.But, tobacco seed usually carries some fungal diseases, as balck shank, rust (Heursel, 1961), stalk break (Lucas, 1965), downy mildew (Lucas, 1975) etc., the entrained disease of seed can continue to cause the serious plant disease in tobacco seedbed and land for growing field crops, though the development of seed coating medicine and application are fallen greatly and reduced the disease that seed carries, some are invaded the interior fungal disease to embryo of seed parenchymas and are also thoroughly controlled.In addition, also contain many pathomycetes in the culture matrix in tobacco seedbed, the normal development of tobacco seedling even land for growing field crops tobacco is had bigger influence.
This case inventor once cultivated a kind of Paecilomyces lilacinus bacterial strain and (was deposited in Chinese typical culture collection center, preserving number " CCTCCNO:M207196 "), and declared Chinese patent, number of patent application is 200710300087.4, discover, Paecilomyces lilacinus (microbial inoculum) growth is fast, it is strong to produce the chitinase ability, can grow rhizosphere surely at tobacco plant, infecting of opposing black shank, and can overcome the bacteriostasis of soil effectively, keep the ability of the inhibition black shank of Paecilomyces lilacinus for a long time.And oligomeric chitosan can not only induce Paecilomyces lilacinus to produce chitinase antagonism tobacco fungal disease, oligomeric chitosan has bacteriostatic activity preferably to fungi and bacterium, and the active increase of the chitinase in the energy inducing plant, to people and animals and environment be perfectly safe (Bi Qingwen etc. the oligomeric chitosan of fly maggot is to the toxicity test of Alternaria alternate, 2007, Hua Zhong Agriculture University's journal).These two kinds of materials can be applied in the seed coating medicine of tobacco seed, just the focus of this case inventor concern.
Summary of the invention
A kind of tobacco seed-coating seed that has disease-resistant encasement that the purpose of this utility model provides at existing problem in the above-mentioned prior art just, this capsuled seed can effectively be controlled the tobacco fungal disease and can induce the fungal disease that produces in soil or the culture matrix in chitinase microorganism antagonism soil or the culture matrix, raw materials used pollution-free, environmentally friendly, the noresidue of encasement.
The purpose of this utility model is achieved through the following technical solutions: the tobacco seed-coating seed that has disease-resistant encasement of the present utility model comprises the seed body, wherein, on the seed body, be coated with Paecilomyces lilacinus antagonism layer and oligomeric chitosan inducing layer successively.
In the utility model, Paecilomyces lilacinus ZY-19-2 antagonism layer thickness is 0.05-0.30mm, and oligomeric chitosan inducing layer thickness is 0.05-0.20mm.
The making of the utility model tobacco seed-coating seed is that the bacteriostatic agent of increase is Paecilomyces lilacinus ZY-19-2 microbial inoculum spore and oligomeric chitosan on the basis of tobacco seed machinery art for coating operation at present.Be specially: with selected, tobacco seed after the classification is measured in the dressing machine of pouring into (LE-450 type tobacco seed dressing machine) in accordance with regulations, start rotary switch then, after treating spin stabilization, add the antagonist (clay among the present invention, surfactant such as Tween 80 etc.) be the Paecilomyces lilacinus spore of matrix), when the capsuled seed diameter reaches 0.05-0.3mm (the antagonism layer thickness is 0.05-0.30mm), the derivant (clay) that adds again among the present invention is the oligomeric chitosan mixed liquor of matrix), when the capsuled seed diameter reaches 0.10-0.50mm (inducing layer thickness is 0.05-0.20mm), can add the special-purpose seed coating medicine of tobacco again.After making the tobacco seed-coating seed through encasement bag quilt, diameter is 2.1-2.5mm, to wrap kind of a rotation polishing in dressing machine pot body then, colouring, carry out air blast when the control temperature is no more than 300 ℃ and dry up, take out capsuled seed then and carry out mechanical drying, after check, quantize encapsulation according to producing needs with encapsulating material (polyester, aluminium foil or polyethylene composite film) by packing machine, vanning at last changes finished room over to.
Major advantage of the present utility model is: easy to process, be fit to suitability for industrialized production, and raw materials used pollution-free, environmentally friendly, the noresidue of encasement.Use capsuled seed of the present utility model,, can effectively control the tobacco fungal disease because the antagonism layer of seed encasement contains Paecilomyces lilacinus ZY-19-2 spore.Inducing layer in the encasement contains oligomeric chitosan; Oligomeric chitosan is a kind of " soft pesticide ", fungi and bacterium there is bacteriostatic activity preferably, and the active increase of the chitinase in the energy inducing plant, people and animals and environment are perfectly safe, and oligomeric chitosan can induce Paecilomyces lilacinus ZY-19-2 to produce chitinase antagonism tobacco fungal disease.Finally reach the purpose that improves yield of tobacco.
