中药复方消毒剂对鸡舍内空气浮游菌杀灭和有害气体降解的试验研究

The Study on Effect of Chinese Herbal Compound Disinfectant to Air Bacteria Killing and Degradation of Harmful Gases in a Henhouse

为了解国内某厂家生产的植物源中药复方消毒剂对鸡舍现场空气沉降菌和有害气体的降解效果。随机选用5间鸡舍,3间分别使用浓度为1∶500、1∶1000的中药消毒剂和百毒杀进行空气消毒,2间为饮用水喷雾对照和空白对照,试验重复3次,每次设计消毒前1 h,消毒后1、4、10和24 h五个时间监测点,采用了细菌自然沉降法和有害气体检测仪对鸡舍内空气浮游菌含量和氨气、硫化氢等有害气体进行了检测,同时还挑选5个养殖工人对鸡舍内除臭效果感官评分。2个浓度的中药消毒剂,在消毒后4 h,杀菌率分别达到95.88%和97.32%,消毒后10 h杀菌率最高,分别为95.07%和99.12%,消毒后24 h杀菌率仍维持90%以上(90%杀菌率为消毒剂合格线)。1∶500浓度要优于1∶1000浓度,但二者间差异不显著(P>0.05)。与消毒前1 h比较,2个浓度的消毒剂四个时间段(消毒后1、4、10和24 h)对氨气和硫化氢的降解,均差异显著(P<0.05);对照消毒剂百毒杀在消毒后1 h杀菌率即达到90%以上,并且持续至24 h后,但对氨气和硫化氢的降解不明显,仅在消毒后10 h显著差异(P<0.05);饮用水对照组在喷雾1 h后,杀菌率为12.17%,其后3个时间段都在1%以内,对对氨气和硫化氢的降解几乎无影响。消毒24 h后,通过养殖工人感官评判,1∶500稀释的中药消毒剂效果最佳,可判定为0级,1∶1000浓度试验消毒剂组、百毒杀组、饮用水对照组和空白对照组均判定为1级,但药物组明显优于对照组。试验设计的中药消毒剂对鸡舍内环境有显著改善作用。

To study the effect of the Chinese bacteria killing and degradation of harmful respectively with a concentration of 1 ： 500, herbal compound disinfectant from a domestic manufacturers to air gases. 5 henhouse were selected randomly disinfection, 3 house 1 ： 1000 Chinese herbal compound disinfectant and Baidusha air disinfection, 2 for drinking water spray control and blank control. The experiment was repeated 3 times, and each was designed 1 h before, 1,4, 10 and 24 h five time monitoring points to detect the content of air bacteria, ammonia and hydrogen sulfide, using the bacterial natural sedimentation and harmful gas detection instrument. And 5 breeding workers were selected to sensory testing on the effect of deodorization. The 2 concentration of Chinese medicine disinfectant sterilization rate reached 95.88% and 97.32% respectively after 4 h disinfection, 10 h after were 95.07% and 99.12%, and 24 h after remained above 90% （90% disinfectant sterilization rate is pass line）. The concentration of 1 ： 500 was better than that of 1 ： 1000, but there was no significant difference between the two groups （ P 〉 0.05 ） hydrogen sulfide （1,4,10 and 24 h） Compared with 1 h before disinfection, the degradation of ammonia and of 2 concentrations of disinfectants for four time periods were significantly different （P〈0.05）. The sterilization rate of the control disinfectant Baidusha reached 90% after 1 h disinfection and continued to 24 h after, but the degradation of ammonia and hydrogen sulfide was not obvious, only after disinfection 10 h significant difference （P〈0.05）. The sterilization rate of drinking water group was 12.17% after spray 1 h, bur the follow of three periods were within 1%, and almost no effect on the degradation of ammonia and hydrogen sulfide. According to the sensory evaluation of the workers, the concentration of 1 ： 500 Chinese medicine disinfectant was the best, judged to be 0, and other groups were determined as 1. The drug groups was superior to the control group. The experimental results proved the disinfectant has significant effect on improving the henhouse environment.
