摘要 为评价刮板式清粪机和传送带式清粪机对兔舍内空气环境质量的影响效果,选取除清粪机械不同外,兔只数、兔生长阶段、风机数量、建筑形式均相同的两栋兔舍,分别在2018年4月连续一周对两类兔舍中的温度、相对湿度、氨气(NH3)、二氧化碳(CO2)、甲烷(CH4)、粉尘、硫化氢(H2S)浓度进行检测。(1)兔舍外、刮板式舍和传送带式舍的温度分别为17.79℃、18.39℃、18.43℃,舍外与舍内温度差异不显著(P>0.05),刮板式舍与传送带式舍内温度差异不显著(P>0.05);(2)兔舍外、刮板式舍和传送带式舍的湿度分别为50.17%、50.3%、48.99%,舍外与舍内湿度差异不显著(P>0.05),刮板式舍与传送带式舍内湿度差异不显著(P>0.05);(3)刮板式舍和传送带式舍内NH3、CO2、粉尘的浓度分别为2.99mg/m^3、813.40mg/m^3、0.31mg/m^3和2.13mg/m^3、614.13mg/m^3、0.31mg/m^3,传送带式舍内NH3和CO2浓度显著低于刮板式舍(P<0.05);未检出H2S、CH4。 To evaluate the effect of two types of manure cleaning machines on air quality in rabbit houses, two rabbit houses with the same number of rabbits, rabbit growth stage, number of fans, and architectural form but different types of manure cleaning machines were selected. The temperature, relative humidity, NH3, CO2, CH4, dust, and H2S concentrations were measured for a successive week in April 2018. Results show (1) the outdoor temperatures, the temperature inside scraper house and conveyor belt house were 17.79 ℃, 18.39 ℃, and 18.43 ℃, respectively, with insignificant difference between outdoor and indoor temperature (P>0.05), and insignificant difference between temperatures inside scraper type and belt type houses (P>0.05);(2)The humidity outdoor and inside scraper house and conveyor belt house were 50.17%, 50.3% and 48.99%, respectively. There was insignificant difference between the indoor and outdoor humidity (P>0.05), nor was the humidity between scraper-type and conveyor belt houses (P>0.05);(3) The concentration of NH3, CO2, and dust in scraper-type and conveyor belt houses were respectively 3.94 ppm, 415.00 ppm, and 0.31 mg/m^3 and 2.8 ppm, 313.33 ppm, and 0.31 mg/m^3, the concentration of contaminated NH3 and CO2 in conveyor belt house was significantly lower than that in scraper house (P <0.05);H2S and CH4 were not detected.
