中文摘要:
      本文在喷杆喷雾机上优化喷洒装置, 采用多喷头组合喷雾, 设计了双扇面喷雾的吊杆喷雾装置, 对单一扇形雾喷头、双扇形雾喷头组合、双扇面吊杆喷雾进行了大田试验, 数据结果显示:标准扇形雾喷头ST110-04(德国Lechler)+双扇面吊杆的喷雾效果最好, 在冠层上中下不同部位的沉积变异系数为28.4%, 在棉花冠层下部的覆盖率达到50.92%, 虫口减退率超过85.0%; 标准扇形雾喷头和防飘喷头组合ST110-02+IDK120-02(德国Lechler)喷雾效果其次; 单一喷头喷雾在冠层下部的覆盖率较小, 为33.14%, 虫口减退率(红蜘蛛)为77.3%。双扇面组合喷雾与单扇面喷雾相比有显著性差异, 不同类型喷头组合的喷雾性能优于其他类型喷头。
英文摘要:
      The objective of this study was to improve the droplet deposition uniformity on cotton canopy. Combined nozzle spray with boom sprayers was used in this study. The pendent boom appliance with double-fan spraying was designed to compare the single normal flat-fan nozzle, double flat-fan nozzle and pendent boom spray in cotton fields. Furthermore, the deposition uniformity and coverage of pesticides and pest control effect were investigated. The spray effect of normal flat-fan nozzle ST110-04 (Lechler)+double flat-fan pendent boom were the best; its deposition variation coefficient in different parts of the canopy was 28.4%; the coverage rate in the lower part of cotton canopy was 50.92%, and the decrease rate of pest insects was more than 85.0%. The spraying effect for the normal flat-fan nozzle and air induction flat-fan nozzle ST110-02+IDK120-02 (Lechler) were second: the coverage rate in the lower part of cotton canopy for single flat-fan nozzle was 33.14%, and the decrease rate of pest insects (the spider mite) was 77.3%. In conclusion, double flat-fan nozzle spraying significantly improves spraying performance.
