超低容量施药是六十年代发展起来的一项新技术。喷雾机具按照在单位面积上喷施药量多少,可分四种:高容量喷雾机每亩喷施药液量大于25升;中容量为6.6～25升;低容量为0.33～0.66升;超低容量少于0.33升。超低容量喷雾是通过高效能的雾化装置,使雾滴变小,在单位面积上仍保持和常规喷雾相同的雾滴数量或农药沉积量。其特点是:雾滴小、均匀,喷液量低,农药含量高。以东方红—18型超低容量喷雾机为例,其优点是:①工效高:日工效为300～500亩,比手动喷雾器高百倍以上。②省药:一般可省药10～30％。③费
Ultra-low capacity application is a new technology developed in the sixties. Spraying machines in accordance with the amount sprayed on the unit area how much can be divided into four kinds: high-capacity sprayer spraying liquid per acre more than 25 liters; in the capacity of 6.6 to 25 liters; low capacity of 0.33 to 0.66 liters; super Low capacity less than 0.33 liters. Ultra-low capacity spray through the high-performance atomization device, so that smaller droplets in the unit area and the conventional spray to maintain the same number of droplets or pesticide deposition. Its characteristics are: small droplets, uniform, low volume spray, high pesticide content. Take Dongfanghong-18 ultra-low volume spray machine as an example, its advantages are: ① high work efficiency: daily work efficiency is 300 ~ 500 mu, more than 100 times higher than manual sprayer. ② provincial medicine: generally can save 10 to 30%. ③ fee
