Abstract
The invention discloses an insect-prevention storage method which comprises the steps as follows: bagging grains and piling into stacks; then sealing the grain stacks and evacuating by a vacuum pump to keep the pressure inside the stacks at 0.05-0.08MPa for 2h; then charging carbon monoxide into the sealed stacks at a speed of 0.5-1g/m<3> and keeping for 5-10h; then evacuating the stacks by the vacuum pump again to keep the pressure in the stacks at 0.02-0.05MPa; charing carbon monoxide into the stacks at a speed of 0.2-0.4g/m<3> and keeping for 5-10h; then slowing charging carbon dioxide into the grain stacks to normal pressure and keeping for 3-4d. With the insect-prevention storage method, less carbon monoxide is charged into the grain stacks to damage the nervous systems of insects in the grains after oxygen is reduced due to evacuation. Besides, the insect-prevention storage method has the advantages of reducing the dosage of the carbon dioxide, having short insect killing time and a good insect killing effect, killing all the insects in 4-5 days about, and reducing the loss of grains.
Description
Technical field
The present invention relates to a kind of storing grain method, be specifically related to a kind of efficient, safe insect protected storing grain method.
Background technology
Grain reserves are the grain consumption demands that be to guarantee the nonagricultural population, regulate grain supply and demand balance inside the province, stablize the grain market price, tackle major natural disasters or other accidents and a material stock system setting up.Annual all have a large amount of grain to be transported into bin storage, grain is infested easily in the deposit process, therefore grain quality is had a greatly reduced quality, solve the insect pest problem in the grain storage process, it is a big problem that must solve in the grain storage process that the quality of grain can not suffered damage.The chemical treatment method of insect protected is to add medicament such as hydrogen phosphide when grain storage, but the long-term use of these medicaments has made insect pest develop immunity to drugs, and insecticidal effect is not ideal enough.Non-chemically processing method has good insecticidal effect, but also can better keep original quality of grain, gets a good review in the recent period, and therefore, the silo insect pest is a main trend of following grain storage insect protected to adopt non-chemically processing method only to put.
Summary of the invention
The present invention is directed to the deficiency of above-mentioned warehouse grain storage, a kind of method of insect protected grain storage is provided, this method can effectively stop the generation of insect pest in the grain, and worm's ovum, larva and adult are all had good fragmentation effect, and does not damage the original quality of grain.
The present invention is achieved by the following measures:
A kind of insect protected storing grain method adopts and divides buttress sealing killing method to carry out grain storage, it is characterized in that step is:
(1) grain divides the buttress sealing: grain is packed in the bag, rick, then with the sealing of grain buttress;
(2) once vacuumize: will vacuumize in the grain buttress with vavuum pump, making the buttress internal pressure is 0.05-0.08MPa, keeps 2h, then with 0.5-1g/m
3Speed in sealing buttress, charge into carbon monoxide, keep 5-10h;
(3) secondary vacuum pumping: vacuumize with vavuum pump once more, making the buttress internal pressure is 0.02-0.05MPa, then with 0.2-0.4g/m
3Speed charge into carbon monoxide, kept then 5-10 hour;
(4) filling CO 2: in the grain buttress, slowly charge into carbon dioxide, kept 3-4 days to normal pressure.
In the above-mentioned insect protected storing grain method, with the airtight film of PVC the grain buttress is sealed, film thickness is 0.15mm.
In the above-mentioned insect protected storing grain method, preferred version is: when vacuumizing for the first time, being evacuated to the buttress internal pressure with vavuum pump is 0.06MPa, then with 0.8g/m
3Speed charge into carbon monoxide; When vacuumizing for the second time, being evacuated to the buttress internal pressure with vavuum pump is 0.03MPa, then with 0.3g/m
3Speed charge into carbon monoxide.
In the above-mentioned insect protected storing grain method, grain gunnysack, woven bag or cloth bag splendid attire, the height of grain buttress is the 12-15 layer.
Grain of the present invention can be cereals such as rice, wheat, corn, also can be beans such as soya bean, mung bean.Insect in the grain mainly contains grain weevil, rice weevil, sitophilus zea-mais, eating-core bean worm, grain peat, rusty grain beetle, red flour beetle, lesser grain borer, India rain moth, booklice etc.
This method is improved on the basis of traditional carbon dioxide Pesticidal technology, charges into a small amount of carbon monoxide after vacuumizing the oxygen minimizing in the grain buttress, and the nervous system of the insect in the grain is suffered damage.In addition, this method only need be filled carbon dioxide one time, has reduced the consumption of carbon dioxide, and the desinsection time is short, effective, can kill whole insects, and reduce grain loss in about 4-5 days.
The specific embodiment
Below by specific embodiment the present invention is further set forth, should be understood that, following explanation only is in order to explain the present invention, not limit it.
Experimental technique
1, sample is prepared
With rice weevil, lesser grain borer, rusty grain beetle, booklice is experiment examination worm, and 30 of above-mentioned examination worms are inserted in the rice of 400g northeast, puts into incubator and cultivates 10 days (25 ℃ of temperature, relative humidity 75%), has worm's ovum to generate.The rice that will have worm's ovum is divided equally into two parts, and a as experimental group, portion is organized in contrast.
2, sample is handled
Experimental group is handled as follows: the rice that will have worm's ovum is put into freshness protection package, and sealing is preserved, and vacuumizes then, makes bag internal pressure between 0.05-0.08MPa, keeps 2h, presses 0.5g/m behind the 2h
3Speed in bag, charge into carbon monoxide, kept then 5 hours.And then vacuumize, the pressure in the bag is controlled at 0.02-0.05MPa, then press 0.2-0.4g/m
3Speed in bag, charge into carbon monoxide, keep 5h then.After vacuumizing for twice, in freshness protection package, charge into carbon dioxide, reach normal pressure, kept 3-4 days until the freshness protection package internal pressure.After the processing, becoming borer population in the rice is 0.
Control group is handled: the rice that just has worm's ovum is put into freshness protection package, keeps 4 days, and becoming borer population in the rice is 37.
3, killing rate calculates
Killing rate (%)=[1-(experimental group becomes borer population/control group to become borer population)] * 100=100%.
