番茄潜叶蛾绿色防控技术

为有效防控番茄潜叶蛾，经过近年来开展的监测预警技术明确了其在宁夏的生物学习性、发生规律、危害特点和分布范围，通过清洁育苗、清洁田园、轮作倒茬等农业防治措施，色板诱杀、性信息素诱杀、迷向诱杀、灯光诱杀等理化诱控技术，以及生物农药、化学农药防治等一系列试验示范，明确了各项技术应用的要点，集成了“监测预警+农业防治+理化诱控+生物防治+科学安全用药防治”的绿色防控技术模式。通过集成的绿色防控技术模式，建立“示范区+农业技术推广部门+种植基地+普通农户”的推广模式并进行大面积应用，指导种植户进行适期防治，有效控制了番茄潜叶蛾的危害，将损失率从30%降低至10%以下，目前在宁夏乃至周边累计示范推广应用0.75万hm²,667 m²新增产值945元，经济效益显著；减少使用农药3次，保障了番茄品质，实现了绿色生产。

Green Prevent and Control Technologies of Phthorimaea absoluta

Abstract: In order to effectively control Phthorimaea absoluta, the biological habit, occurrence law, damage characteristics and distribution range of Phthorimaea absoluta in Ningxia had been clarified through monitoring and early warning technologies carried out in recent years. The key points of various technological applications had been clarified by agricultural control measures of pollution-free seedling, cleaning fields and crop rotation, as well as physical and chemical control technologies of color plate trapping, sex pheromone trapping, mating disruption and light trapping, as well as a series of experimental demonstrations of biological and chemical pesticides control. Finally, a green prevention and control technological mode of ''monitoring and early warning + agricultural control + physical and chemical induction control + biological control + scientific and safe applicating pesticides to control'' was integrated. Through the integrated green prevention and control technology mode, a promotion mode of ''demonstration zone + agricultural technology promotion department + planting base + ordinary farmers'' had been established for large-scale application, guiding planters to carry out timely prevention and control, effectively controlling the harm of Phthorimaea absoluta, reducing the loss rate from 30% to below 10%. Currently, a total of 7 500 hm2 has been demonstrated and promoted in Ningxia and its surrounding areas, increating production value of 945 yuan per 667 m2 with significant economic benefits. The application of pesticides were reduced three times, which ensured the quality of tomatoes and achieved green production.
