为确保春季枸杞病虫害的封园工作顺利开展,必须提前对防治机械进行检修与维护保养,有条件的产区可根据各自的产地生境及相关的技术方案进行硬件改进。(1)发动机的检修。及时检修发动机中的各种故障,对于有问题的零部件要及时进行更换,并及时清洗发动机外表的油污。(2)冷却系统的检修。由于防治器械大多属于水冷系统的柴油机,春季如果温度在0℃以下,就必须把发动机的放水阀打开,将机体内的水排干。
In order to ensure the successful opening of the garden of the wolfberry diseases and insect pests in Spring, the prevention and cure machinery must be overhauled and maintained in advance. The qualified producing areas can be hardware improved according to their respective habitats and relevant technical solutions. (1) engine maintenance. Timely maintenance of the engine in a variety of failures, the timely replacement of the parts in question, and promptly clean the engine surface of the oil. (2) cooling system overhaul. As most of the prevention and control equipment belongs to the water-cooled diesel engine, if the temperature is below 0 ℃ in spring, the engine drain valve must be opened to drain the water in the body.
