【摘要】：【目的】試驗(yàn)旨在對(duì)八層層疊式籠養(yǎng)密閉式雞舍冬季環(huán)境質(zhì)量進(jìn)行測(cè)定和分析,為層疊式籠養(yǎng)密閉式雞舍環(huán)境控制提供依據(jù)�！痉椒ā渴褂铆h(huán)境智能監(jiān)控系統(tǒng)和粉塵采樣器每天6:00-8:00、12:00-14:00和18:00-20:00測(cè)定八層層疊式籠養(yǎng)密閉式雞舍水平和垂直方向上不同位置的環(huán)境質(zhì)量參數(shù)(溫度、相對(duì)濕度、風(fēng)速、光照強(qiáng)度、CO_2濃度、粉塵濃度、氨氣濃度和PM10)。【結(jié)果】在采取側(cè)窗進(jìn)風(fēng)、縱向通風(fēng)的通風(fēng)模式下,冬季八層層疊式籠養(yǎng)蛋雞舍內(nèi)平均溫度、相對(duì)濕度、風(fēng)速和光照強(qiáng)度分別為19.11℃、52.02%、0.25 m/s和34.00 lx,空氣中平均二氧化碳濃度、粉塵濃度、氨氣濃度和PM_(10)分別是2083.22 mg/m~3、2.85 mg/m~3、1.04 mg/m~3和26.01μg/m~3。不同測(cè)定點(diǎn)之間環(huán)境質(zhì)量存在差異,從濕簾端到風(fēng)機(jī)端雞舍溫度、二氧化碳濃度、氨氣濃度、粉塵濃度和PM_(10)濃度呈逐漸增大的趨勢(shì),上層測(cè)定點(diǎn)H_(3.80m)、H_(4.50m)和H_(5.10m)的溫度、二氧化碳濃度和氨氣濃度顯著高于下層測(cè)定點(diǎn)H_(0.60m)、H_(1.30m)和H_(1.90m)。相關(guān)分析結(jié)果表明,風(fēng)速與溫度、二氧化碳濃度、氨氣濃度、粉塵濃度呈極顯著負(fù)相關(guān),溫度與氨氣濃度呈顯著正相關(guān)�！窘Y(jié)論】冬季八層層疊式籠養(yǎng)雞舍內(nèi)不同位置環(huán)境質(zhì)量參數(shù)存在差異,環(huán)境質(zhì)量基本符合《畜禽場(chǎng)環(huán)境質(zhì)量標(biāo)準(zhǔn)》(NY/T 388-1999)。
[Abstract]:[objective] the purpose of the experiment was to determine and analyze the environmental quality of eight layers of closed chicken coop in winter. [methods] using the environmental intelligent monitoring system and dust sampler to determine the different positions in horizontal and vertical directions of 8 layers closed chicken coop with 6: 00-8: 00, 12: 00-14: 00 and 18: 00-20: 00 every day. Environmental quality parameters (temperature, Relative humidity, wind speed, light intensity, concentration of CO _ 2, dust concentration, ammonia gas concentration and PM10 ~ (10). [results] under the ventilation mode of side window and longitudinal ventilation, the average temperature and relative humidity of eight layers of layers cage hens in winter, The wind speed and light intensity were 19.11 鈩，
