荔枝果园风送式喷雾机喷药的思考

Thoughts on Spraying Medicines by Air Sprayer in Litchi Orchards

针对荔枝果园喷药效率低、费工、费药等问题,采用风送式喷雾机,分别在缓坡地、丘陵缓坡地和丘陵山地等不同地形荔枝果园进行喷药作业,探究风送式喷雾机与传统人工管道喷药效率及成本投入的差异。结果表明,风送式喷雾机喷药效率是管道喷药的4倍以上,节省药水量40%以上,该结论为荔枝果园机械化应用提供借鉴。

In order to solve the problems of low spraying efficiency and labor-intensive in litchi orchards,this paper uses air-driven sprayers to spray litchi orchards in three different terrains:gentle slopes,hilly slopes,and hills.Differences in spraying efficiency and cost input between air-driven sprayer spraying and traditional manual pipe spraying were analyzed.The results showed that the spraying efficiency of airdriven sprayers is more than 4 times to pipeline spraying,save more than 40% of the amount of liquid medicine.In addition,to achieve simple and efficient cultivation management,we provided some suggestions for the development of air-driven sprayers and the fusion of machines and agronomy.
