Abstract: In view of serious influence of henhouse environment（temperature，humidity and dust）on growth and development of broilers，high-pressure space electric field sterilization was carried out on henhouse environment dust removal，environment monitoring system with single chip microcomputer STM32 as control core was used to monitor broiler farm equipped with high-voltage space electric field.The best distribution position was determined by cluster analysis，and changes of temperature，humidity and dust before and after corona discharge were analyzed.Results showed that，after corona discharge，average temperature in henhouse decreased by 0-3~0-8 ℃，and change rate was 1-20%~2-60%.Average relative humidity decreased by 5%~9%，and change rate was 9-03%~12-81%.Average concentration of dust PM2-5 was reduced by 33-66~98-33 μg/m3，and change rate was 34-56%~57-39%.Average concentration of dust PM10 was reduced by 34-00~54-34 μg/m3，and change rate was 29-39%~36-79%.Corona discharge had a certain effect on humidity and had a very obvious removal effect on dust in henhouse environment.
