摘要
根据气流理论，用仓外与粮堆相通的黑色管道的构成循环系统，利用昼夜温差形成慢速环流气流，加速ＰＨ３气体在粮内的扩莠和渗透，达到了较好的杀虫效果。
According to the airflow theory, the circulatory system with the black aerationducts which were introduced into grain bulk from outdoor storage accelerated diffusionand permeation of PH3 through slow circulatory airflow which was produced through theheat absorbed of the black duct in daytime and the difference in temperature of day andnight. The circulatory system had good fumigation effect.
