当前有一些国家开始逐步推广使用一种微型喷咀喷灌。这种喷灌系统是在1969年首先在南非研制成功。微型喷咀多数是由塑料做的由基盘和顶盘两部分组成。喷咀直径为0.75～1.75毫米,工作压力为0.7～1.76公斤/厘米~2,喷水量为15.5～181.2升/小时,射程为1.5～4.0米.可以作全园喷洒也可以 At present, some countries have begun to gradually promote the use of a micro-nozzle irrigation. This sprinkler system was first developed in South Africa in 1969. Most micro-nozzle is made of plastic by the base plate and the top plate of two parts. The nozzle diameter of 0.75 ~ 1.75 mm, the working pressure of 0.7 ~ 1.76 kg / cm ~ 2, the amount of water spray 15.5 ~ 181.2 l / h, a range of 1.5 to 4.0 meters. Can be used for spraying the whole park can
