在珠江三角洲水稻地区,常常遭受鼠类为害,窃食孕穗,损失甚重。据作者1959—1960年调查,发现当地为害水稻的鼠类有11种,拟褐鼠占优势;其次为小家鼠和褐家鼠,此外,还有黄胸鼠、板齿鼠等。鼠的洞穴多筑在稻田堤围上,昼伏夜出,它们的食性很杂,除为害水稻外,尚为害甘薯、甘蔗等。防治鼠害以化学防治为主,为了保穗,可在早晚造孕穗以前(早造4月或5月上旬,晚造7—9月间)调制2%磷化锌甘薯毒铒或用2%磷化锌螃蟹毒铒效果良好,成本也低。
In the Pearl River Delta rice area, often suffer from rodents, stealing booting, loss is very serious. According to the survey conducted by the author from 1959 to 1960, 11 species of rodent pests were found to be harmful to rice in the local area, and brown rat was dominant, followed by Mus musculus and Rattus norvegicus. In addition, there were Rattus flavipectus, Banded rat and so on. More rat caves built in the paddy fields embankment, nocturnal, their food is very mixed, in addition to damaging rice, but also harmful to sweet potatoes, sugar cane and so on. Prevention and treatment of rodent pests mainly chemical control, in order to spike, in the sooner or later to make bosom before (early in April or early May, late made 7-9 months) to prepare 2% zinc phosphide sweet potato poisoning or 2% Phosphatidylcholine crab erbium good effect, the cost is low.
