摘要
在农业生产系统中,保护农作物免受杂草、昆虫、病菌等的危害是作业过程中的一个重要环节,而目前农作物保护最主要的手段是用化学农药。现代不断开发的高效农药在理论上可以使农药有效成分的使用量减少到每公顷数千克以内,但是在实际中这样少量的农药能否有效地得到投放是一个值得怀疑的事情。为此,通过喷杆式喷雾机喷雾质量影响因素分析,为农药的合理使用在技术上提供参考依据。
In the agricultural production system, protects the crops to be exempt from the weed, the insect, the germ and so on harm is a important link in work process, but the most main method of crops protection are applying chemical pesticide at present. The modem highly effective pesticide may theoretically cause the amount of the use of the pesticide effective component to reduce to several kilograms each hectare, but whether the such few pesticide is effectively applying in reality are the matters which is dubious. This article attempts through analyzing influencing factors of atomization quality of spray rod type spraying machine, provides technically the reference for the pesticide reasonable using.
