摘要
为寻找在柑橘树中沉积分布较好且能够高效灭杀柑橘木虱的雾滴粒径,选取了同一型号、不同粒径的4种喷头在柑橘树中进行试验,所选喷头型号为Lanao YZK8001、YZS8002、YZS8003、YZS8004等4种型号,并分别将4种喷头安装在搭建的龙门架上进行试验。选取的柑橘树树龄在3~5年,试验在密闭防虫网内进行,通过试验测定各个喷头在柑橘树树冠中的雾滴沉积分布。结果表明:2号防虫网在柑橘树冠层表面的雾滴沉积分布最好,为50.40%;3号防虫网内雾滴在冠层内部的穿透性最好,主要是因为雾滴太小飘移严重,雾滴太大无法穿过果树叶片。在喷施相同药液的前提下,不同粒径的雾滴对柑橘木虱的灭杀效果不同,对木虱灭杀效果最好的为2号防虫网,在施药1天后的虫口减退率达到80%。试验得出了在柑橘树中沉积分布性能好且对木虱灭杀性好的雾滴粒径,为实际喷雾作业参数的设置提供了参考[1]。
In order to find the droplet size of the citrus tree which is well distributed and can effectively kill the citrus hibiscus,this paper selects four kinds of nozzles of the same model with different particle sizes to test in the citrus tree.Four models of Lanao YZK8001,YZS8002,YZS8003 and YZS8004 were installed on the constructed gantry for testing.The selected citrus tree is 3-5 years old and the test is carried out in a closed insect net.The distribution of droplets in the canopy of citrus trees was determined by experiments.The results showed that the distribution of droplets on the surface of citrus canopy was the best,which was 50.40%.The droplets in the No.3 insect net were in the crown.The penetration inside the layer is the best,mainly because the droplets are too small to drift,and the droplets are too large to pass through the leaves of the fruit trees.Under the premise of spraying the same liquid,the droplets of different particle sizes have different killing effects on citrus hibiscus.The best killing effect on hibiscus is the No.2 insect net,and the insect mitigation rate after 1 day of application Up to 80%.In this paper,the particle size of the mites is determined by experiments,which provides a reference for the actual spray operation parameters[1].
