四川丘区旱作主要生物灾害防治策略与技术

四川丘陵区是四川省面积最大、人口分布最集中的区,伴随着农业重心从成都平原转向盆中丘陵,四川丘区农业成为全省经济特别是农业的重要区域.近年来,由于异常气候和生态环境恶化,农业生物灾害常年影响丘陵地区农业活动,制约了丘区的农业生产和经济发展.因此,为了绿色安全地进行农业生产活动,笔者总结了丘区旱作农业主要生物灾害的防治策略...

Major Biological Disasters of Dry Farming in Sichuan Hilly Areas: Control Strategy and Technology

The hilly areas of Sichuan have the largest area and the most concentrated population in the province. Along with the agricultural production center transferring from Chengdu plain to the hilly basin, agriculture in Sichuan hilly areas has become an important part of the provincial economy. In recent years, due to the abnormal climate and the deterioration of ecological environment, agricultural biological disasters have influenced agricultural activities and restricted the agricultural production and economic development in hilly areas. Therefore, in order to carry out agricultural production safely and efficiently, we summarize the prevention and control strategies and technologies of the main biological disasters of dry farming in hilly areas. It is proposed that we should take biological disaster monitoring and early warning as the prerequisite and basis for the control, and strengthen agricultural control measures and plant quarantine inspections by taking chemical, physical, and biological preventive measures. At the same time, we should monitor, diagnose and prevent the occurrence of dry farming diseases, insects, weeds and rats and other biological disasters in hilly areas with the help of high-tech means, so as to accelerate the green development of agriculture in hilly areas and improve the quantity and quality of agricultural products.
