摘要
本文综合报道了四川农业害鼠的种类、分布、群落结构、发生规律、监测技术、年龄判别技术、鼠害调查、防治指标及化学防治最佳组配方案。四川农业害鼠分布可概划为盆地、盆周、盆西、盆西南及川西北五大生态区;限制黑线姬鼠数量增长的主要外界因素包括日照、降雨、温度和种群分布状态。研究制定了农田害鼠“三定”监测技术和黑线姬鼠年龄判别的数学模型新技术;指出了鼠害防治指标是一个动态指标;农田鼠害程度调查宜采取平行线跳跃式方法;文章提出的“春季灭鼠,分片定量,定向投饵”及相应的配套技术,经上千万亩试验示范证明可节省投入30～50％,灭效高于90％,无鼠害持续时间达11个月以上,每亩挽回粮食10公斤以上。
This paper described briefly of the species, distribution, community structure, developed rule, surveillance, age structure and its identificufion, damage research technology, economic threshold, control technics and so on were also conducted to rats and mice In agriculture.
The paper divided the rodents ecological distribution areas from Sichuan, China, into inside area round area; west area, south-west area and north-west area of base according to the species and environment, sunlight hours, precipitation, temperature and state of population distribution Were the major environmental conditions to limit the population numbers of Apodemus agrarius Pallas, two new technologies of 'Three-Difined' rodents surveillance and age identification to Apodemus agrar-ius Pallas had been discussed; the economic threshold to rat damage control was dynomics; the opit-mum sampling technology to rat damage study was Parallel-Jumping method. The rats control was described carefully, and put out 'Control in spring, baits quantified by field and baits deposited by localization' and the other relative technologies had been extented about (6.6 million hectare in last three years, It indicated that cost decreased about 30-50%, more than 90% rats be killed, and more than 11 months with rat free, 150kg grains could not be destroyed Pre-harvest perha.
