    摘要:

    通過風(fēng)洞試驗(yàn)與除草劑田間藥效試驗(yàn)對擋板導(dǎo)流式罩蓋進(jìn)行了性能測定。結(jié)果表明：罩蓋防飄噴霧系統(tǒng)的最優(yōu)結(jié)構(gòu)參數(shù)為擋板寬度40cm、擋板傾角50°、噴頭傾角50°。噴施除草劑30d后，使用此罩蓋噴霧技術(shù)的株數(shù)防效為81.4%、鮮重防效為76.4%，均優(yōu)于常規(guī)噴霧。當(dāng)藥劑用量減少20%時(shí)仍然可達(dá)到與常規(guī)噴霧相同的防效，實(shí)現(xiàn)減量噴霧，節(jié)約了農(nóng)藥，降低了成本。

    Abstract:

    Guided baffle shield application is effective and economical method to reduce droplets drift. The performance research of this system was carried out with wind tunnel experiment and field trials of herbicide.The results showed that the optimum structure parameters of the guided baffle shield sprayer were: shield width of 40cm, shield angle of 50°, nozzle angle of 50°. 30 days after herbicide application, the weeds control effects was 81.4%, fresh weight effects was 76.4% which were superior to conventional application; when the herbicide dosage reduced by 20%, the effect with shield application was same to conventional application. So the guided shield application could save pesticide and reduce cost. 
