Abstract
The invention relates to a pesticide, particularly relates to using calcium cyanamide or calcium cyanamide and calcium oxide for vanishing maggots. The invention can be used to treat feces of human and animal with harmless treatment, the breeding flies are blocked from the sources, the invention can vanish the flies well, reduce the damage of flies which is one of the four pests to human without environmental pollution, increase the fertilizer efficiency of animal and human excreta, while the calcium cyanamide is decomposed completely in the water without residues. After calcium cyanamide is decomposed, the outcome does not pollute the environment. When the animal and human excreta containing the mixture of calcium cyanamide or calcium cyanamide and calcium oxide is used as fertilizer, the fertilizer efficiency and nitrogen content are improved efficiently, so while killing maggots with calcium cyanamide, the nitrogen content is increased, the product is economical and environmental friendly, and has good economical effect.
Description
Technical field
The present invention relates to a kind of insecticide, particularly utilize nitrolim or nitrolim and calcium oxide to be used to the maggot of going out.
Background technology
Fly is the object that people eliminate by every means as one of " four pests " always." maggot " is screwworm, and the rotten smelly dirt of fly happiness food gets over generally, and the food of biting can both pollute germ virus, and people and animals have just eaten and fallen ill easily.The main disease of propagating infecting both domestic animals and human has tens kinds of cholera, dysentery, hepatitis and tuberculosis etc., also can propagate parasitosis such as the roundworm of infecting both domestic animals and human and lung filaria, and harm is big.The key measure of fly-killing is the larva of fly-killing, and common method is with 1% chlorophos solution, periodically sprinkle or adopt the method for heat kill, be exactly awfully hot hot chaff tepetate on animal manure, cover the maggot in the manure pit of can suffocating completely but will seal.But in the said method, adopt the chlorophos solution maggot of going out, can produce serious pollution environment.And adopt the method for heat kill very inconvenient.
Summary of the invention
The purpose of this invention is to provide and a kind of people, animal ight soil is carried out harmless treatment, can block easy to use, the medicine of the maggot of going out that cost is low of growing chain of fly and the using method of this medicine from the source.
For achieving the above object, the technical scheme that is adopted is:
Nitrolim is used to the maggot of going out.
The composition of nitrolim and calcium oxide is used to the maggot of going out.
Nitrolim and calcium oxide are used to the maggot of going out, and it is characterized in that in the above-mentioned composition, and the weight ratio of nitrolim and calcium oxide is 1: 1-0.5.
Nitrolim be used to the to go out using method of maggot;
In people, animal ight soil, add the nitrolim of human and animal excreta weight 0.25-2%, placed the maggot of just can going out 12 hours to 168 hours.
The composition of nitrolim and calcium oxide be used to the to go out using method of maggot;
In people, animal ight soil, add the nitrolim of human and animal excreta weight 0.5-4% and the composition of calcium oxide, placed the maggot of just can going out 12 hours to 168 hours.
The composition of nitrolim and calcium oxide is used to kill the using method of maggot, it is characterized in that the weight ratio of nitrolim and calcium oxide is 1 in the above-mentioned composition: 1-0.5.
By a large amount of evidences, the present invention has following characteristics:
1, the present invention can carry out harmless treatment to people, animal ight soil, and the maggot of going out is effective, can effectively cut off the [of fly from the source, because usage amount is few, environmentally safe, the maggot cost that goes out is very low, and can increase the fertilizer efficiency of human and animal excreta and the stink of minimizing human and animal excreta.
If after maggot thoroughly killed, thereby can utterly destroy fly.By experimental results demonstrate, in the non-irrigated lavatory of rural area practicality, put into the composition of a certain amount of nitrolim or nitrolim and calcium oxide, the maggot of can effectively going out, the amount of fly and the stink in non-irrigated lavatory also reduce simultaneously, can effectively improve environment, and because nitrolim is a kind of slow release fertilizer, in the maggot of going out, can improve the fertilizer efficiency of human and animal excreta, replenish calcium fertilizer deficiency in the soil, environment, soil are not had influence, and can effectively alleviate of the influence of non-irrigated lavatory stink environment, when other animal wastes are handled, also can reduce stink simultaneously.
2, nitrolim can decompose in water fully, and noresidue can not impact environment.When the composition as fertilizer sources of ight soil and nitrolim or nitrolim and calcium oxide uses in the farmland, mixed catabolite can be utilized by plant absorbing as nitrogenous fertilizer, therefore, when utilizing nitrolim killing maggot, nitrogenous fertilizer is provided again, not only economy but also environmentally friendly, and because usage amount is little, the cost of fly eradication and maggot is low.
