Knapsack sprayer fired rice pests " annihilation

Recent positive hybrid rice tillering to jointing stage round stalk , due to climatic reasons , leaf roller and planthoppers intrusion, the main hazards to feeding rice leaf roller Inaba , causing Inaba rolled up , the whole white leaf blight , leaf photosynthesis can not be normal , empty husks rate increased , weight decreased, resulting in production. The clump of rice planthoppers will base sucking sap that is harmful brown necrosis, nutrients and moisture loss , causing yellow leaves , growth low , seriously affecting rice production . " These two types of pest invasion , fast, fast breeding , harm is also large, large area by pest sprayer speed of fear is too late , using sprayer ideal ." Said the person in charge of plant protection station .

It is understood that , with the hand sprayer for pest control and disease prevention, slow, poor spray pesticides , loss, and the power of small spray , spray pesticides can only stay in the rice leaf surface and can not penetrate the rice plexus , resulting in pest control is not complete. The motorized sprayer reflected the effect is: spray speed, every seven minutes to complete an acre spray , spray with high pressure, good atomization , high utilization , the use of a pressure sprayer can be sent directly to the pesticide less Inaba position , can be full "destroy" pests and diseases. The knapsack sprayer spray rice and found that rice leaf surface , rice straw on pesticides has been atomized mist beads, pest and disease prevention effect is obvious. Large grain Zhang Mingsheng said: " We passed the preliminary conclusions drawn comparison test : manual sprayers can only complete one acre per hour spraying tasks, while sprayer reaches 10-12 acres per hour , a difference of 10 times ergonomics , and greatly reduce the labor intensity . knapsack sprayer because the pressure is high, thin cloud point , prevention is better than ordinary sprayers and spraying the machine back on the body , with the hand sprayer as easy . "

Local agricultural experts believe that the knapsack sprayer finish 50-60 acres per day , the cost of pesticides per acre savings of 17.9% . Use self-propelled sprayer indeed reduce the labor intensity of farmers and medication costs, improve production efficiency, pest prevention and control to ensure the effective time , to solve the security source management of rice diseases and insect pests . Limited Fusite this bottle sprayer , 2009 also supports directory into the country , in the work against the ruling system will flourish , full lay rice pest " war of annihilation ."
