St udy on the Comprehensive Prevention and Control Technology of Rice Blast in Nanchong Area
摘要
Abstract
Nanchong city is one of the frequent and serious areas of rice blast in Sichuan Province. Comprehensive prevention and control technology of rice blast were studied and applied since 1997, and made significant achievements. The results showed that dif-ferent varieties have different resistance to rice blast. The control effect of hybrid rice and glutinous rice intercropping to hybrid rice leaf blast were 45.23%~69.85%, to glutinous rice leaf blast were 61.69%~75.14%45%, to hybrid rice panicle blast were 46.03%~62.41%, to glutinous rice panicle blast were 65.58%~74.82%. Do a good job of infected rice straw and overwintering pathogen source treatment before sowing and transplanting would postpone the occurrence of rice blast. The occurrence degree of rice blast in health cultivation treatment was lighter 10%~30% than conventional cultivation or excessive application of nitrogen fertilizer treatment. The suitable agents and best control period were determined.关键词
