最近,国外一些国家为了降低喷灌能源消耗,提高喷洒质量,降低成本,研究了上百种喷滴结合喷头或称微型喷头,这些喷头要求的工作压力低,喷灌强度小,特别适宜地形坡度陡,土壤透水性差或要求雾化条件高的作物。一、进口直径有两种见图1 SYM4×× D=10毫米(外螺纹) Recently, in order to reduce the energy consumption of sprinkler irrigation, improve the spraying quality and reduce the cost, some foreign countries have studied hundreds of sprinkler combined sprinklers or micro sprinklers. These sprinklers require low working pressure and small sprinkling intensity and are especially suitable for steep terrain, Crops that have poor soil water permeability or require high fogging conditions. First, the import diameter of two see Figure 1 SYM4 × × D = 10 mm (male)
