摘要: 【目的】分析JT-30多旋翼植保无人机喷施缩节胺(DPC)对调节棉花生长的影响,研究植保无人机在棉花化控作业中的应用效果,为植保无人机在棉花化控作业的应用提供指导。【方法】与喷杆式喷雾机作业相比,采用JT-30六旋翼植保无人机喷施DPC作业,分析其对棉花株高、果枝长度、节间距等的影响。【结果】JT-30植保无人机喷施DPC 5、10、14 d后能够有效抑制棉花的株高,抑制率分别为7.26%、15.81%和21.17%;喷杆喷雾机作喷施作业后对应的抑制率为8.55%、16.81%和 22.80%;JT-30植保无人机喷施DPC对棉花株高的抑制效果与喷杆式喷雾机作业效果相当。在果枝长度、节间长度和果枝始节高度等指标上表现出了相似的结果,且高浓度DPC没有对棉花表现出药害作用。【结论】植保无人机喷施缩节胺可以有效促进棉花营养生长向生殖生长的转移、塑造良好株型、提高成铃率,且高浓度DPC对棉花无药害,具有与常规喷施相当的效果。

Abstract: 【Objective】 To explore the application effect of spraying 1,1-dimethyl-piperidiniuchloride (DPC) on regulating cotton growth by multi-rotor plant protection unmanned aerial vehicles(UAV), we carried out the experiment of regulating the growth of cotton by JT-30 UAV.【Method】In this paper, the effects of DPC for cotton plant height, length of fruit branches and length of internodes sprayed by JT-30 UAV was studied.【Result】The plant height of cotton was effectively inhibited after spraying 5 d, 10 d, and 14 d by JT-30 UVA, and the inhibition rates were 7.26%, 15.81% and 21.17%, respectively. The corresponding inhibition rates after spraying 5 d, 10 d, and 14 d by boom sprayer were 8.55%, 16.81% and 22.80%, respectively. The results showed that the inhibition effect on the plant height by spraying DPC on cotton by JT-30 plant protection UAV was equivalent to that of DPC sprayed by rod sprayer. Namely, there was no significant difference between the two kinds of application instruments. Similar results were also observed in the length of fruit branches, length of internodes, and the height of the first fruiting branches. In addition, high concentration of DPC did not show any effect of drug damage on cotton.【Conclusion】The above results showed that DPC sprayed by plant protection UAV could effectively promote the vegetative growth of cotton to the transfer of reproductive growth, create a good plant type and increase the boll rate, which displayed the same equivalent effect as boom sprayer and reached the requirements of cultivation management. The study of this paper was of high theoretical significance for the mechanization, modernization and standardization of machine-made cotton.
