Abstract


Abstract: The method for UAV spraying of cotton defoliating agent in theYellowRiver basin was investigated in this study through comparison of a one-time pesticide application experiment and a two-time pesticide application experiment.  The experiment was carried out using a Jifei P30 multi-rotor electric UAV.  The experiment was divided into five different treatments, the first treatment was the one-time pesticide application to Jinfeng 103 cotton, the second treatment was the two-time pesticide application to Jinfeng 103 cotton, the third treatment was the one-time pesticide application to Lumianyan 37 cotton, the fourth treatment was the two-time pesticide application to Lumianyan 37 cotton, and the fifth treatment was blank test.  The cotton plant defoliation and opening of bolls were observed at 5, 10, 15, and 20 days under five different treatments, and statistical analysis was conducted to analyze variations in wadding and defoliation rate for the different treatments.  The results showed that the effects of defoliation rates and vomiting rates were better than those of the control group, and the effect of the two-time pesticide application of the same variety of cotton was better than that of the one-time pesticide application.  By observing defoliation and wadding after applications, the defoliation effect was determined to be faster than the wadding effect.  The costs of one-time pesticide application and two-time pesticide application were also compared, and the cost of the two-time pesticide application was approximately 1.58 times as much as the cost of the one-time pesticide application. Therefore, it is suggested to select the two-time pesticide application mode when spraying defoliant agent on cotton.
