    摘要:

    為了研究不同類型和大小的液壓噴嘴,、不同生物農(nóng)藥噴霧樣本對(duì)霧滴特性的影響,，采用激光粒度分析儀,、噴幅寬度測定裝置等對(duì)美國Teejet公司的平面扇形噴嘴XR8004,、XR11004和中空錐形噴嘴TXA8002,、TXVK8004等4種常規(guī)噴嘴和7種不同噴霧樣本（普通自來水和6種美國Bioworks公司的生物農(nóng)藥）,，分別對(duì)相同和不同噴霧壓力,、相同噴霧高度和相同噴霧環(huán)境下的霧滴粒徑大小分布,，以及相同噴霧壓力和相同噴霧高度下噴幅寬度等特性進(jìn)行了對(duì)比試驗(yàn)研究,，并對(duì)結(jié)果進(jìn)行分析。結(jié)果表明：在分別與水以一定比例混合后,，原液狀生物農(nóng)藥的霧滴粒徑與水的霧滴粒徑大小差異不顯著,，但比原粉末狀生物農(nóng)藥霧滴粒徑尺寸大；生物農(nóng)藥在同一噴嘴噴霧下,，霧滴粒徑隨噴霧壓力增大而減?。辉谙嗤瑖婌F壓力情況下,，霧滴粒徑大小分布均勻度隨噴嘴噴量速率的增大而減小,，噴量速率越大，其粒徑尺寸越分散,、越不集中,；噴嘴噴幅寬度的大小隨噴霧角度增大而增大，不同類型生物農(nóng)藥的噴霧樣本對(duì)噴幅寬度影響不大,。因此,，根據(jù)以上噴嘴和生物農(nóng)藥的噴霧特性，對(duì)于不同的農(nóng)作物選擇適當(dāng)?shù)膰娮煨吞?hào),、噴量流速和噴霧壓力來噴施農(nóng)藥,，可以提高農(nóng)藥的噴霧效率和有效性。

    Abstract:

    In order to study the effects of different biological pesticides samples on the droplet characteristics with different types and size hydraulic nozzles, a particle/droplet laser image analysis system and a portable spray pattern analyzing system were used to investigate the spray droplet characteristics of biological pesticides with hydraulic nozzles. Spray parameters included the spray droplet size distributions and spray pattern widths. Seven different spray samples (water and six types of biological pesticides manufactured by Bioworks Inc.) were tested with two Teejet flat fan nozzles (XR8004 and XR11004) and two Teejet hollow cone nozzles (TXA8002 and TXVK8004) under laboratory conditions. Droplet size distribution was evaluated at the same and different spray pressures separately and the same spray height. In addition, the spray pattern width was determined at the same spray pressure and the same spray height. The results showed that there was no significant difference between the droplet size of the liquid biological pesticide after mixing with water in a certain proportion and the droplet size of water, and the droplet size of the liquid biological pesticides was higher than that of the powdery biological pesticide mixture with water. The droplet size of biological pesticide sprayed was decreased as the spray pressure increase for the same nozzle;the droplet size distribution uniformity was decreased as the increase of the nozzle flow rate, and the larger the spray flow rate was, the more dispersed the particle size was. The spray pattern width was increased as the increase of the spray angle, and different biological pesticide samples had little effect on the spray pattern width. Therefore, proper selection of nozzle types, spray pressure and flow rate was necessary for discharging particular biological products to achieve optional spray application efficiency and effectiveness.
