The second is to strengthen publicity and launch. In the past six years, * * * has distributed nearly 2 10000 publicity materials, distributed 5000 prevention and control patterns, played "Citrus Huanglongbing Science and Education Film" 67 times, and publicized 100 times on radio and television, making the prevention and control work a household name. Carry out various forms of technical training to further improve the recognition ability of citrus Huanglongbing. * * * Held more than 270 trainings, with 1.56 million person-times, and organized 207 scientific and technological consultations at all levels, with 1.2 1.00 million person-times.
The third is to carry out a comprehensive epidemic investigation and dig out the diseased plants. Since 2002, the general survey of epidemic situation has adopted the method of combining self-reporting by the masses with professional team investigation, and conducted a comprehensive survey according to the requirements of not leaking villages, villages, gardens, blocks and factories. Census data are divided into villages and households, registered and recorded, and epidemic situation files are established. In the past six years, * * * organized 4320 census teams in the whole region and investigated 34,965,600 citrus trees. By the end of 2007, citrus Huanglongbing had been found in 17 townships (streets) and 205 administrative villages, with the cumulative number of infected plants1353,700, and the affected area of the disease park was 27,250 mu.
On the basis of epidemic investigation, the method of combining self-digging by the masses and organizing professional teams to cut down diseased trees was adopted to dig out diseased trees thoroughly. Towns (streets) invested funds and organized professional teams to cut down and clean up the diseased trees in out-of-control orange orchards. For example, Gao Qiao Street and Qiaoyuan Town organized professional logging teams to cut down the diseased trees in the diseased orange orchards one by one. In particular, Gao Qiao Street organized professional felling teams for four consecutive years from 2004, which lasted for two to three months every year, and all the diseased trees in the orange orchards of all villages in the street were cut down. In the past six years, the cumulative number of infected plants in the whole region was 6.5438+0.3537 million. The occurrence range of citrus Huanglongbing has been shrinking, and the number of diseased plants has been decreasing. The continuous prevention and control has achieved practical results.
The fourth is to do a good job in the prevention and control of psylla and seedling management. ① Strengthen the control of psyllid. Monitoring points are set up in Tangjiaqiao of Qiaoyuan Town and Li Jiayang Village of Shangyang Town. Since 2002, information on the prevention and control of psyllid has been released irregularly every year, focusing on the prevention and control of psyllid in spring, summer and autumn, and classified and guided according to the occurrence base of psyllid. In August, 2007, 86,000 packages of pesticides for controlling psyllids were provided free of charge to six demonstration areas for comprehensive control of citrus Huanglongbing and 1.850 mu citrus orchard, which effectively promoted the control of psyllids on the surface. From 2002 to 2007, the control area of psyllid in the whole region reached more than 6.5438 0.88 million mu, and the control compliance rate was 90%. ② Do a good job in seedling quarantine management. During the transportation of seedlings and grafting in winter and spring every year, it is forbidden to transport seedlings and scions to epidemic areas inside and outside the province. At the same time, the quarantine inspection of citrus seedling market has been strengthened. In the past six years, 86,000 diseased orange seedlings have been destroyed, and the spread of the disease has been controlled from the source.
The fifth is to grasp the construction of demonstration areas. Take Caijiayang Village, Minjian Village, Dongao Village of Shangyang Township and Duanjiang Village of Toutuo Town in Cheng Nan as demonstration areas for citrus Huanglongbing prevention and control. These orange orchards are not only demonstration areas for comprehensive control, but also windows to show the control effect. The demonstration area pays attention to adaptive cultivation and psyllid control, and has achieved good results. For example, there are 978 mu of citrus in Caijiayang Village and Minjian Village in Cheng Nan, and 50 diseased trees were found in 2007. According to the investigation in Qiaoyuan town in 2006, the rate of diseased plants in suitable orchards was only 4.3%, while the rate of diseased plants in the control area reached 65438 06.3%.
Sixth, increase support. From 2003 to 2008, the district finance allocated 6.28 million yuan of subsidy funds, which effectively guaranteed the development of citrus Huanglongbing prevention and control work.
