喷雾机使用性能的好坏直接影响着灭草效果,我们发现使用喷雾机喷药后出现以下问题:①不同作业幅灭草效果不一;②同一作业幅内各行间灭草效果不一;③同一作业幅前后不同位置灭草效果不一。产生以上问题的主要原因是喷雾机没有达到标准技术状态,作业中液泵压力不足或不稳,喷头流量不均,雾化不良,搅拌不均或不搅拌等。
Sprayer performance directly affects the performance of weed control effect, we found that the use of spray sprayer after the following problems: ① different operations amplitude weeding effect varies; ② the same operation within the various lines weeding effect varies; ③ Before and after the same operation in different positions weeing different effects. The main reason for the above problems is that the sprayer has not reached the standard technical condition, the pump pressure is not enough or unstable during the operation, the flow rate of the spray head is uneven, the atomization is poor, the stirring is uneven or the stirring is not performed.
