Abstract
The present invention relates to a kind of broad spectrum insecticidal method, the main characteristic lies in that the farmland is covered with thin film, and the insecticidal poison gas is sprayed into the space in the film, over 98% of agricultural injurious insects can be killed. It overcomes the bad inseticidal effect of the current method and is suitable for insecticidal work for rice and yam family.
Description
The present invention relates to agrotechnique, particularly a kind of broad-spectrum deinsectization method is applicable to the farmland deinsectization.
Existing deinsectization method generally is to spray insecticide on crops, and its poor effect or waste are big, particularly can't kill the insect of piece root stem tubers such as underground insect such as potato.The net for killing winged insects that Chinese patent 91218856.1 proposes also can't improve the deinsectization technology.
The objective of the invention is to overcome the deficiency of above-mentioned existing agriculture deinsectization technology, and provide a kind of energy 98 percent ground to kill the broad-spectrum deinsectization method of agricultural pests.
The object of the present invention is achieved like this: the plastic film that will not have perforation has been covered in crops and field in large area with sealing, sprays deinsectization poison gas then in it, keeps 1-10 days.
Advantage of the present invention is to kill the insect of the crops of short bar, and effect reaches more than 98 percent.Particularly be applicable to crops deinsectizations such as paddy rice, wheat.
Describe embodiments of the invention and details thereof below in detail:
The present invention is that the plastic foil with intact atresia is covered on the crops such as paddy rice, wheat, sweet potato, vegetables in large area, each limit of film is embedded in hermetically in the mud soil in field, and the space that film is surrounded is airtight with the external world as far as possible.Use air extractor then, vavuum pump for example, the air in this space is extracted and spray into deinsectization poison gas, for example: gaseous state agricultural chemicals, content are the high concentration carbon dioxide gas more than 90% etc.Sealing kept 1-10 days, and insect will die like a rat or be choked to death.The deinsectization effect can reach more than 98 percent, even absolutely.
Claims (3)
1, a kind of broad-spectrum deinsectization method that adopts plastic film and agricultural chemicals is characterized in that, with plastic membrane sealing be covered on the crops field, the space sprays into deinsectization poison gas in film then.
2,1 described broad-spectrum deinsectization method as requested is characterized in that, with air extractor the space air that film surrounds is extracted, and sprays into deinsectization gaseous state agricultural chemicals.
3, broad-spectrum deinsectization method according to claim 1 is characterized in that, the deinsectization poison gas that sprays into can be that concentration is the carbonic acid gas more than 90 percent.
