为了推进“绿色植保”、探明生物导弹在南充市防治玉米螟的效果,减少农药用量及残留和环境污染与防治成本,确保玉米生产、品质和生态环境安全,促进玉米增产增收,采用灯下诱蛾和田间剥查与试验示范相结合等方法,开展生物导弹防治玉米螟效果和效益研究。结果表明,每公顷投放生物导弹30~37对,平均防效78.0%,防治成本139.50~172.50元,比化学农药防治少142.50~168.00元,玉米产量比空白对照区平均高817.8 kg,增产11.0%,增加产值1799.16元,增收节支1941.66~1967.16元。2003—2014年累计示范推广24507.33 hm2,增产2004.21万kg,新增产值4409.26万元,节省防治费用349.23~411.72万元,增收节支4758.49~4820.98万元,减少农药5%杀虫双大粒剂551.41 t或90%杀虫单使用12.87 t。且生物导弹使用简便,劳动强度小,适于老、弱、妇、幼操作,对人畜和环境安全,节省药械和用水,是有机农业、现代农业、绿色和无公害农产品及IBM绿色防控示范园区防治玉米螟、减少化学农药的理想替代产品。
In order to promote the “green plant protection”, to find out the effectiveness of biological guided missiles in preventing and controlling corn borer in Nanchong, reduce pesticide use, residual and environmental pollution and prevention and control costs, ensure corn production, quality and ecological environment, and promote the increase of corn yield. Light moths and field stripping and test demonstration combined with other methods to carry out bio-missile control corn borer effect and benefit research. The results showed that 30 to 37 pairs of bio-missiles per hectare were put into operation, with an average control effect of 78.0% and a prevention and control cost of 139.50-172.50 yuan, which was 142.50-168.00 yuan less than that of chemical pesticides. The yield of maize was 817.8 kg higher than that of the blank control area, , Increase output value 1799.16 yuan, increase income and save 1941.66 ~ 1967.16 yuan. From 2003 to 2014, a total of 24507.33 hm2 of demonstration and extension products were produced, with an output of 2004.21 million kg and an added output value of RMB40.4926 million, saving on prevention and control costs of 349.23-4.1172 million yuan, an increase of 4758.49-4848.98 million yuan in revenue and expenses, and a reduction of pesticide 5% t or 90% pest use 12.87 t. The biological missile is easy to use and has low labor intensity. It is suitable for old, weak, young women and children. It is safe for human beings and animals and the environment, and saves medicine and water. It is an organic agriculture, modern agriculture, green and pollution-free agricultural product and IBM’s green prevention and control demonstration Park prevention and control of corn borer, the ideal alternative to reduce chemical pesticides.
