作物根外喷肥在防倒、抗旱、防病、合理用肥、提高作物产量等方面都有一定的作用。根外喷肥时要注意的一个重要问题是要选用喷雾均匀、雾粒细小、喷雾速度快、使用轻便,适于大面积使用的喷雾器。最近在我省广泛试用的静电喷雾器(原称超低量电动喷雾器),基本上能符合这些要求。静电喷雾器由电源(1.5伏于电池8节)、微型电动机驱动塑料叶片转动的喷头、盛装喷液的塑料瓶等三个主要部件组成。它原用于喷施农药,后经我们改装,加大喷嘴孔径和喷液量,同样适用喷施各种肥料。用静电喷雾器喷肥比用一般背负式喷雾器有以下优
Root crop fertilizer outside the root in the down, drought, disease prevention, rational use of fertilizer, improve crop yields and so has a certain role. An important issue to be aware of when spraying fertilizer outside the root is to use a spray that is evenly sprayed, small mist particles, fast spray speed, light weight and suitable for large area use. Recently widely used in our province electrostatic spray (formerly known as ultra-low volume electric sprayer), basically meet these requirements. Electrostatic sprayer from the power supply (1.5 volts in the battery 8), miniature motor-driven plastic blades rotating nozzle, filled with spray plastic bottles and other three major components. It was originally used to spray pesticides, after we modified, increase the nozzle aperture and spray volume, the same spray applied to all kinds of fertilizers. Spray with electrostatic spray than with the general knapsack sprayer have the following advantages
