摘要
针对浅圆仓"热皮冷芯"的客观现实,对有害虫的储粮采用少量药剂多点常缓施药的方法,既有效地杀灭粮堆表层和上层的害虫,又充分利用粮堆"热皮冷芯"现象控制粮堆中心和下层虫害的生存,发挥"热皮冷芯"效应,确保储粮长期安全保管;同时也避免采用整仓环流熏蒸,因环流通风破坏了"热皮冷芯"效应,增大了药剂投放和粮堆中心粮温上升而带来储粮的安全隐患。通过多点常缓施药对浅圆仓"热皮冷芯"粮堆熏蒸的尝试,以期寻找更为科学合理的用药途径。
The reality of ＂hotskin but coldcore＂is an objectivein Squat of grain storage. Amethod has been taken by usinga smallmulti--dose chemicalwith varieties spraying so that the chemicals eould be released slowly. The experiment sueeessfully proved that it is not only effeetively to kill pests in both the uppersurfaee andthe grain bulk, but also eontrol the survive rate of lower bulk pests. By making full use of ＂hot skin but cold core＂ effect of grain bulks ean ensure the long--termsafetygrain storage, alsoavoid the use ofthe entire circulation fumigation in warehouse since the ventilation could destroy the ＂cold--hot skin＂ effect, inereasing the center ofthe grain bulk drug delivery andraisegrain storagetemperature which could bringhid- den dangers. The experimentofmulti--dosing ＆ slow releasing in ＂hot skin but cold core＂ grain bulk in squat fumigationis an attempttofind a more scientific and reasonable way for grain storage.
