Problems solved by technology

[0004] At present, there are many kinds of pesticides on the market, most of which are chemical pesticides. These pesticides are highly toxic and powerful, and play a certain role in killing insects and bacteria on crops.

However, because these pesticides are highly toxic and difficult to decompose, they have great side effects on the use of food, melons, fruits, vegetables and other crops, often causing food poisoning and chronic iron poisoning. Accidents are not uncommon, and the incidence of cancer and other difficult and strange diseases caused by chronic poisoning has increased sharply, which will seriously endanger people's physical and mental health; Increase the amount of medicine per mu, so that the cost continues to rise, but the control effect is mediocre
