摘要:

【目的】研究地表温度、土壤含水量对春尺蠖羽化的影响,为提高虫害防治效率、降低防治成本提供理论依据。【方法】以新疆克拉玛依市开发区为例,选择有代表性的12块林地(P0~P11),利用实测春尺蠖羽化量数据、地表温度及土壤含水量卫星数据,采用趋势、相关性及回归方法,分析春尺蠖羽化量的时空分布特征及其变化趋势,研究地表温度、土壤含水量在时空维度对其羽化的影响。【结果】(1)点P3、P4、P10、P11所处林分春尺蠖虫害最严重,P6所处林分虫害水平始终较低。(2)春尺蠖逐日羽化量与地表温度呈正相关,与土壤含水量呈负相关,且这种相关性主要集中在羽化高峰日前。(3)点P5、P7、P8所处林分内土壤含水量与春尺蠖逐日羽化量的负相关性较大。(4)2021年羽化高峰日前,地表温度主要通过蒸发效应影响土壤含水量进而间接影响羽化进程,而2022年地表温度对羽化则主要表现为直接影响。【结论】地表温度、土壤含水量对春尺蠖羽化的影响是一种综合效应。在适宜春尺蠖羽化的土壤温湿度范围内,地表温度的上升或土壤含水量的下降会促进羽化,反之则抑制羽化,且这种影响主要集中在羽化高峰日前。点P5、P7、P8所处林分内土壤含水量与春尺蠖逐日羽化量的负相关性较大,可在这些区域内开展人工灌溉从而抑制春尺蠖的发生。

Abstract:

【Objective】 To study the effects of surface temperature and soil water content on the emergence of Apocheima cinerarius Erschoff, and to provide theoretical basis for improving the efficiency of pest control and reducing the cost of pest control. 【Methods】 In this study, the development zone of Karamay,Xinjiang, was taken as an example, select 12 representative forest areas(P0-P11). Based on the measured data of the emergence of Apocheima cinerarius Erschoff, the satellite data of surface temperature and soil moisture content, the temporal and spatial distribution characteristics and trends of the emergence of Apocheima cinerarius Erschoff were analyzed by trend analysis, correlation and regression analysis, and the effects of surface temperature and soil moisture content on its emergence in the spatial and temporal dimensions were discussed. 【Results】 (1)The pest damage of Apocheima cinerarius Erschoff was the most serious in P3, P4, P10 and P11, and the pest damage level of P6 was always low. (2)The daily emergence of Apocheima cinerarius Erschoff was positively correlated with surface temperature and negatively correlated with soil water content, and this correlation was mainly concentrated before the peak day of emergence. (3)The negative correlation between the soil water content and the daily emergence of Apocheima cinerarius Erschoff at P5, P7 and P8 was larger.(4)Before the peak of emergence in 2021, the surface temperature mainly affected the soil moisture content through the evaporation effect and indirectly affected the emergence process, while the surface temperature in 2022 mainly affected the emergence directly. 【Conclusion】 The effects of surface temperature and soil water content on the emergence of Apocheima cinerarius Erschoff are a comprehensive effect.Within the range of soil temperature and humidity suitable for the emergence of Apocheima cinerarius Erschoff, the increase of surface temperature or the decrease of soil water content will promote the emergence, and vice versa, it will inhibit the emergence, and this effect is mainly concentrated before the peak day of emergence. In the spatial dimension, the soil water content in the stands of P5, P7 and P8 has a great negative correlation with the daily emergence of Apocheima cinerarius Erschoff. Therefore, artificial irrigation can be carried out in these areas to inhibit the occurrence of Apocheima cinerarius Erschoff.
