【摘要】：現(xiàn)代集約化、規(guī)�；竽辽a(chǎn)存在舍內(nèi)空氣質(zhì)量惡化問題,粉塵、有害氣體及微生物蓄積,進而影響畜、禽健康和生產(chǎn)。筆者在舍內(nèi)加裝人工負(fù)離子發(fā)生裝置,研究空氣負(fù)離子對雞舍中需氧菌總數(shù)、粉塵含量和氨氣濃度的影響,探討其在雞舍空氣凈化中的應(yīng)用。采用兩棟完全相同的雞舍,通過2個試驗研究人工負(fù)離子對雞舍空氣環(huán)境的改善效果及有效作用時間。試驗1,加裝人工負(fù)離子發(fā)生裝置雞舍為試驗組,無負(fù)離子發(fā)生裝置雞舍為對照組,在不同時間點采樣測定;試驗2,分別設(shè)置不同負(fù)離子發(fā)生功率,在負(fù)離子發(fā)生前、發(fā)生時及發(fā)生后不同時間采樣測定。結(jié)果表明,在該試驗條件下,人工負(fù)離子能顯著降低雞舍內(nèi)需氧菌總數(shù)和粉塵含量(P0.05),而且具有明顯的時間效應(yīng)(P0.05),0.5μm以下粉塵含量不受負(fù)離子處理時間的影響(P0.05),1.0μm及以上粉塵含量隨處理時間的延長明顯降低(P0.01),空氣負(fù)離子對雞舍內(nèi)氨氣含量沒有顯著影響(P0.05);相對于低發(fā)生功率(32 W),43 W發(fā)生功率下空氣負(fù)離子對雞舍內(nèi)粉塵和需氧菌清除效率更高,開啟負(fù)離子發(fā)生裝置30min后,可保持雞舍內(nèi)需氧菌總數(shù)30min和粉塵含量60min內(nèi)處于明顯降低狀態(tài)(P0.05)。結(jié)果提示,空氣負(fù)離子可用于改善雞舍空氣環(huán)境質(zhì)量,有利于畜、禽健康生產(chǎn)。
[Abstract]:Modern intensive and large-scale livestock production has problems of deterioration of air quality, accumulation of dust, harmful gas and microorganism, which affects the health and production of livestock and poultry.An artificial anion generator was installed in the house to study the effect of air negative ion on the total number of aerobic bacteria, dust content and ammonia concentration in chicken house, and its application in the air purification of chicken house.Two identical chicken coops were used to study the effect of artificial negative ions on the improvement of the air environment and the effective time of action.In experiment 1, artificial anion generating device was added to the chicken house as the test group, and the non-negative ion generating device chicken house was used as the control group to sample and measure at different time points; in experiment 2, different negative ion generating power was set up, before the negative ion occurred,Sampling time was measured at and after occurrence.The results show that, under the experimental conditions,Artificial negative ions can significantly reduce the total number of domestic oxygen bacteria and dust content in chicken coop, and have obvious time effect. The dust content below 0.5 渭 m can not be affected by the time of negative ion treatment. The dust content above 1.0 渭 m and above is not affected by the treatment time.There was no significant effect of negative air ion on ammonia content in henhouse, and the removal efficiency of air negative ion on dust and aerobic bacteria in chicken house was higher than that at low power of 32 W ~ (-1) ~ (43 W).When the negative ion generator 30min was turned on, the total 30min and dust content of 30min and dust content 60min in the chicken house could be significantly decreased (P 0.05).The results suggest that air anion can be used to improve the air quality of chicken house and be beneficial to the healthy production of livestock and poultry.
