中文摘要:为了提高果园喷雾的农药利用率,减少因农药地面流失而造成的环境污染,针对果园传统连续喷雾作业时存在过量喷洒和树间无效喷雾的特点,基于3WGZ-500型风送自走式喷雾机设计了自动对靶喷雾系统。该系统采用超声波传感器测距方式探测果树(传感器量程为0.35~2m,发射角为60°,喷药机两侧分别以15°均布5个)。根据传感器信号,控制与相应位置喷头对应的上、中、下3组管路电磁阀的开合,实现自动对靶喷雾。以5a树龄的苹果园为试验对象,在喷雾压力0.5MPa时,开展不同作业速度(1.3、1.7、4.5、7.2km/h)下果树冠层的有、无对靶喷雾试验,并与传统喷雾机喷药对照,结果表明:作业速度对3WGZ-500型喷雾机有、无对靶喷雾时的农药利用率影响不大,自动对靶喷雾系统开启时的农药利用率为35.8%,比关闭时的27.6%提高了29.7%,较传统喷雾机18.7%的农药利用率提高了91.4%,可大幅减少农药用量;3WGZ-500型喷雾机在不同作业速度的农药地面流失率十分接近,有对靶时地面流失率平均13.3%,相对无对靶时的18.86%降低了42%,说明对靶喷雾系统有效降低了对生态环境的污染。

Abstract:In order to improve the pesticide application efficiency and reduce the agricultural chemicals lost in orchard spraying, an automatic target spraying system based on the 3WGZ-500 self propelled sprayer was designed in view of excess spraying and ineffective spray at fruit trees clearances during traditional spray operation. Ten ultrasonic sensors were fixed on the two sides of the orchard sprayer at 15° intervals, which were used to measure the distance between the nozzles and sprayer targets. The sensor measure range was 0.35~2m and emission angle was 60°. Based on the sensor signals, three channel solenoid valves by side were used to control the switch of nozzles at the corresponding position. The experiment was worked at the five years old apple orchard, test spray pressure was 0.5MPa and operating speed was 1.3km/h, 1.7km/h, 4.5km/h and 7.2km/h respectively. The result showed that the operating speed had little effect on pesticide application efficiency at the condition of with target spraying system and without target spraying system. This target spraying system can reduce unnecessary spraying chemical pesticides. The pesticide application efficiency was 35.8% with target spraying system, which increased 29.7% compared to without target spraying system’s 27.6% and increased 91.4% compared with traditional spray’s 18.7%. The system can effectively reduce the pollution to the environment. Ground loss rate at different operating speeds was proximity. The ground loss rate was 13.3% with target spraying system, which reduced by 42% compared to without target spraying system’s18.86%.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
