Abstract
A kind of high temperature of super-dry rice seeds is xeothermic to commit genocide biography pest and disease damage method, is related to arviculture plant protection technology, can be killed without agricultural chemicals and kind pass a pest and disease damage, including step is as follows：1. ultra-dry seeds are handled：Common drying is obtained into dry seedses, it is placed in ventilative mesh bag in thermostatic drying chamber or similar drying equipment, 45 DEG C of temperature of temperature 40 DEG C are first set to dry 5 to 8 hours, moisture drops to 8% 11%, 65 DEG C of temperature of temperature 55 DEG C are set to dry again 12 to 18 hours, seed moisture content is down in 5% 7%, obtains ultra-dried seed；Step will be completed, and 1. temperature setting in former drying equipment, is that 80 DEG C of 90 DEG C of heated dry airs dry 24 48 hours, kills the pest and disease damage of seed institute band by gained ultra-dried seed；After the cooling of ultra-dried seed high temperature dry heat treatment is taken out, allow seed to get damp again 37 days, nursery is carried out according still further to Nostoc commune Vanch sprout method.
Description
Technical field
The present invention relates to arviculture plant protection technology, belong to arviculture production field.
Background technology
Crop seeds can all carry a variety of germ polypides, venereal bacteria polypide of even quarantining, and can cause with seed dispersal
Pest and disease damage occurs for crop, so as to influence the quality of crop growth and crop, yield, pest and disease damage is passed here it is planting.Rice seed
Sub the same all to carry a variety of germ polypides, even quarantine pest and disease damage has a strong impact on paddy growth and yield.Existing market
Indiscriminate diversion rice is adjusted disorderly, kind is more drawn frequently, causes pest and disease damage multiple, how effectively to prevent and treat kind of a biography pest and disease damage, peasant is most
Kind of a biography pest and disease damage is killed using agricultural chemicals seed soaking sterilization, but effect is not highly desirable, and some are planted biography pest and disease damage such as viral difficulties and killed.
In seed dry heat sterilization research field, being currently known the pest and disease damage of seed institute band can go out at 75 DEG C -85 DEG C xeothermic 24-48 hours
Kill, but conventional paddy rice dry seedses were in 75 DEG C of -85 DEG C of dry heat treatments 24-48 hour that then seed vitality understands serious loss, lost
Seed practical value.Therefore till now, still without find can penetration and promotion high temperature be xeothermic on a large scale kills kind a biography in Rice Production
Pest and disease damage method.
The content of the invention
The invention solves the problems that technical problem：There is provided a kind of high temperature of super-dry rice seeds xeothermic biography pest and disease damage method of committing genocide,
Kind of biography pest and disease damage is killed without agricultural chemicals thoroughly, adapts to carry out penetration and promotion application in Rice Production.
The present invention implements technical scheme：A kind of xeothermic biography pest and disease damage method of committing genocide of high temperature of super-dry rice seeds, step is such as
Under：
1. ultra-dry seeds are handled：LIPIDS OF DRY RICE EMBRYO seed material is used, common drying dry seedses are obtained into, its water content is entered in≤15%
It is heated at high temperature drying after row elder generation low temperature, obtains ultra-dried seed, practical operation is mounted in seed in ventilative mesh bag and is placed on freeze-day with constant temperature
In case or similar drying equipment, 40 DEG C of -45 DEG C of temperature of temperature are first set to dry 5 to 8 hours, moisture drops to 8%-11%, then sets temperature
55 DEG C of -65 DEG C of temperature of degree are dried 12 to 18 hours, and seed moisture content is down in 5%-7%, obtains ultra-dried seed；
2. ultra-dried seed high temperature dry heat treatment：Step will be completed, and 1. gained ultra-dried seed in former drying equipment, improves temperature immediately
The xeothermic biography pest and disease damage of committing genocide of degree, is that 80 DEG C of -90 DEG C of heated dry airs dry 24-48 hours by temperature setting, kills the disease of seed institute band
Insect pest；
3. seed presoaking and germinating is handled：After the cooling of ultra-dried seed high temperature dry heat treatment is taken out, seed is allowed to get damp again 3-7 days, according still further to
Nostoc commune Vanch sprout method carries out nursery, such as uses germination incubator, or carries out presoaking and germinating with other methods, cultivates strong
Health seed bud is seeded into rice seedling bed.
The remarkable advantage of the present invention：1. rice seedling bed seedling rice blast and bakanae disease are investigated, it was demonstrated that the identical seed of identical rice varieties
The ultra-dried seed criticized compares conventional method using the technology of the present invention in the rice shoot that high temperature dry heat treatment is bred as（Disappear without any seed
Poison processing）The average prevention effect of the rice shoot of incubation, seedling rice blast and bakanae disease respectively reaches 89.7% and 100%.2. the invention is reduced
Pesticide use, protecting agriculture ecological environment：Seed soaking sterilization agricultural chemicals is saved first, with high temperature dry heat treatment super-dry rice seeds, no
Need to be soaked seed with agricultural chemicals again and sterilize, secondly reduce rice terrace Pesticide use, by killing kind of a biography pest and disease damage, during reducing paddy growth
Pest and disease damage occurs, and it is that some quarantine pest and disease damages and simple species pass pest and disease damage especially to reduce, so as to reduce Pesticide use, is subtracted
Few agricultural product pollution by pesticides, protecting agriculture ecological environment.3. the xeothermic biography disease pest of committing genocide of the high temperature of the super-dry rice seeds of the invention
Evil technology is simple, and cost is low, the biography that can commit genocide pest and disease damage, and does not influence seed quality, and this invention can be popularized in Rice Production
Popularization and application.
