不同植保机械施药对水稻病虫防治效果的研究

Research on Control Effect of Rice Diseases and Pests Using Different Machinery Spray Pesticides

对自走式喷杆喷雾机、多旋翼植保飞行器、背负式机动弥雾机3种不同植保机械施药的作业效果及水稻病虫防治效果进行比较。结果表明,自走式喷杆喷雾机与植保飞行器工效远高于背负式机动弥雾机,是背负式机动弥雾机的6.7~10.0倍。且自走式喷杆喷雾机用工成本较低,每公顷24元,植保飞行器用工成本每公顷36元,是背负式机动弥雾机的1/5~1/3。多旋翼植保机飞行器喷药速度比自走式喷杆喷雾机快,但电池充电耗时较长。自走式喷杆喷雾机喷幅宽,喷雾均匀、用水量足,与多旋翼植保飞行器均适用于大面积推广,值得应用。多旋翼植保飞行器对水稻病害的防治效果较差,其用水量与病害控制效果有一定的关系,建议加大用水量或添加沉降剂使用。

The effect of homework,control effect of rice diseases and pests were compared,which were three different machinery spraying pesticide the self-propelled spray boom sprayer,multi-rotors aircraft,motorized knapsack mist sprayer.The results showed that the self-propelled spray boom sprayer and multi-rotors aircraft work efficiency were much higher than motorized knapsack mist sprayer,which was 6.7 to 10.0 times of motorized knapsack mist sprayer.And low labor costs,the self-propelled spray boom sprayer labor costs was only 24 yuan per hectare.The multi-rotors aircraft labor costs was 36 yuan per hectare,which was 1/5~1/3 of motorized knapsack mist sprayer.The multi-rotors aircraft spraying speed was faster than the self-propelled spray boom sprayer,but battery charging time was longger.The self-propelled spray boom sprayer had the advantage of spraying range wide,spray evenly and plenty of water.The self-propelled spray boom sprayer and the multi-rotors aircraft are suitable for large area promotion and worthy of application.The control effect of the multi-rotors aircraft to rice disease is poorer,which might have a certain relationship with the water consumption.When the multi-rotors aircraft sprays pesticide should be used more water or join the settling agent.
