Abstract
The invention discloses a new method for preventing sweet potato soft-rot disease. The new method for preventing sweet potato soft-rot disease is characterized by comprising the following steps: timely harvesting the sweet potatoes, avoiding mechanical damages, carefully selecting healthy sweet potatoes, safely storing the sweet potatoes in a cellar, carrying out early-stage storage, carrying out middle-stage storage, and carrying out late-stage storage and the like, so that the method is capable of realizing the purpose of preventing sweet potato soft-rot disease. The method is easy to operate, well in effect, free of additional cost input and especially suitable to the northern regions for sweet potato storage. The method is capable of effectively preventing and treating sweet potato soft-rot disease as well as reducing disease incidence.
Description
Technical field
The present invention relates to farm crop and store diseases prevention field, be the prevention and controls of a kind of sweet potato soft rot specifically.
Background technology
Sweet potato soft rot is that sweet potato is gathered and one of main disease of storage period. When sweet potato water content height, between storage period, very easily raw soft rot, if do not paid attention to, will cause Ipomoea batatas to rot in a large number.
Summary of the invention
The present invention solves current sweet potato to store the deficiency in diseases prevention technology, invents a kind of method preventing sweet potato soft rot.
The present invention is for solving the problems of the technologies described above, and the technical scheme taked is, a kind of method preventing and treating sweet potato soft rot, and its special character comprises following process engineering:
1, gather in the crops in good time, avoid physical abuse. Summer potato to be harvested around the Frost's Descent, and autumn potato to be harvested before the Beginning of Winter, and fine day will be selected to gather in the crops, and reduces as far as possible or avoid producing wound when digging potato.
2, selected strong potato, accomplishes that safety enters cellar for storing things. Before sweet potato enters cellar for storing things selected, eliminate potato sick, residual, rotten, aqueous vapor enters cellar for storing things after drying, as far as possible with newly storing. Will old mamoty in cellar for storing things except exposing new soil before old cellar for storing things, it is possible to every square metre carries out fumigation sterilization with 15 grams, sulphur.
3. storage in earlier stage, namely enters to store in latter 30 days, and the groundwork of this period is ventilation, insulation and falls apart wet, and temperature controls below 15 DEG C, and humid control is 90% ~ 95%. Utilize ventilation hole or door and window, with good conditionsi utilize exhaust fan, add forced ventilation. If day temperature height, it is possible to take open evening, daytime close method; Later along with the decline gradually of temperature, ventilation hole can be opened night day and close, and can no longer ventilate in time storing temperature and be stabilized in below 15 DEG C.
4, preserving mid-term, namely to this period in the beginning of spring in the early stage of after, cellar for storing things temperature reduces, and is the period that potato block is the most easily damaged to plants caused by sudden drop in temperature, and heat-insulating and cold is the focus in this period, makes cellar for storing things temperature be not less than 10 DEG C, preferably controls at 12 DEG C ~ 14 DEG C. Closing ventilation hole or door and window, thicken cellar for storing things external thermal insulation, potato heap is upper covers straw mattress or mollugo.
5, anaphase storage, namely after the beginning of spring, outside air temperature raises gradually, running check cellar for storing things temperature, remains on 10 DEG C ~ 14 DEG C, and noon, temperature too high was leaked informaton in time, closes air port in time at dusk, cellar for storing things temperature is remained within optimum range.
Technique effect
The technique effect of the present invention is, adopts above-mentioned technical scheme, it is possible to realize a kind of method of sweet potato soft rot, the method is simple to operate, effective, it does not have extra cost drops into, especially it is applicable to area, the north and stores sweet potato use, can effectively prevent and treat sweet potato soft rot, reduce the incidence of the state of an illness.
Embodiment
1, gather in the crops in good time, avoid physical abuse. Summer potato to be harvested around the Frost's Descent, and autumn potato to be harvested before the Beginning of Winter, and fine day will be selected to gather in the crops, and reduces as far as possible or avoid producing wound when digging potato.
2, selected strong potato, accomplishes that safety enters cellar for storing things.Before sweet potato enters cellar for storing things selected, eliminate potato sick, residual, rotten, aqueous vapor enters cellar for storing things after drying, as far as possible with newly storing. Will old mamoty in cellar for storing things except exposing new soil before old cellar for storing things, it is possible to every square metre carries out fumigation sterilization with 15 grams, sulphur.
3. storage in earlier stage, namely enters to store in latter 30 days, and the groundwork of this period is ventilation, insulation and falls apart wet, and temperature controls below 15 DEG C, and humid control is 90% ~ 95%. Utilize ventilation hole or door and window, with good conditionsi utilize exhaust fan, add forced ventilation. If day temperature height, it is possible to take open evening, daytime close method; Later along with the decline gradually of temperature, ventilation hole can be opened night day and close, and can no longer ventilate in time storing temperature and be stabilized in below 15 DEG C.
4, preserving mid-term, namely to this period in the beginning of spring in the early stage of after, cellar for storing things temperature reduces, and is the period that potato block is the most easily damaged to plants caused by sudden drop in temperature, and heat-insulating and cold is the focus in this period, makes cellar for storing things temperature be not less than 10 DEG C, preferably controls at 12 DEG C ~ 14 DEG C. Closing ventilation hole or door and window, thicken cellar for storing things external thermal insulation, potato heap is upper covers straw mattress or mollugo.
5, anaphase storage, namely after the beginning of spring, outside air temperature raises gradually, running check cellar for storing things temperature, remains on 10 DEG C ~ 14 DEG C, and noon, temperature too high was leaked informaton in time, closes air port in time at dusk, cellar for storing things temperature is remained within optimum range.
