在四川东部地区,中期测报以期距法较为实用。短期测报应按稻型、品种、移栽期、生育期以及田间蛾卵密度和卵块孵化进度进行。处于分蘗期的双季晚稻和分蘗末期的一季晚稻,亩卵块在100块以上,即可列为防治对象田,根据卵块密度和孵化进度确定防治次数和适期。較为簡化的防治标准是初見“新枯心”时施第一次药,以后根据卵块密度酌情再施一次,可将枯心率压低至1％以下。药剂治螟应掌握时間标准(即卵孵进度)及数量标准(卵块密度或侵入幼虫密度)职确定施药适期和次数。每亩用6％六六六1.5—2斤泼苗或撒毒土均可,但須有1—2寸的水层深度。
In the eastern part of Sichuan Province, the mid-term measurement is more practical by the period method. Short-term report should be based on rice type, variety, transplanting, growth period and field moth egg density and egg hatching progress. The late rice at the tillering stage and the late rice at the end of the tillering season are more than 100 mu eggs, which can be listed as the control field. According to the egg mass density and hatching schedule, the number of prevention and control and the appropriate period are determined. A more simplified prevention and control standard is the initial application of “new heartbreaking” when the first drug application, according to the egg mass density, as appropriate, and then applied once, the heart rate can be reduced to below 1%. Pharmacy governance borer should master the time standard (ie egg hatch) and the number of standards (egg density or density of invaded larvae) to determine the appropriate duration and frequency of administration. Per mu with 6% six six 1.5-2 pound splashed seedlings or soil can be sprinkled, but there must be 1-2 inches of water depth.
