ZY-2喷头组合喷灌对农田小气候的影响研究

Effect of ZY-2 Sprinkler Combined Irrigation on Farmland Microclimate

采用CR1000自动传感器,测试了ZY-2摇臂式喷头组合喷灌条件下,高度1、3、5、7、9 m处干湿球温度,目的是研究喷灌对不同高度处空气温度和相对湿度的影响。结果表明,组合喷灌导致1 m和3 m高度处空气温度降低和相对湿度增大,温差、相对湿度差最大值分别出现在12:00及16:00左右,温差值、相对湿度差最大值分别达到13.8℃、49.7%,最小值出现在05:00左右,分别为0.1℃、5.2%。组合喷灌对温度、相对湿度的影响一般是持续到喷灌结束后20 min。

Using the CR1000 automatic sensor test under the ZY-2 combined impact sprinkler irrigation conditions different height 1,3,5,7,9 m department of dry and wet bulb temperature,to study the effect to different height of air temperature and relative humidity.The results show that the combined sprinkler irrigation led to the air temperature decrease and relative humidity increases in the height of 1m and 3 m,the maximum difference of temperature,relative humidity appear in about 14：00 pm,the values arrive to 13.8 ℃,49.7 % respectively,the minimum difference of temperature,relative humidity appear in the early morning about 05：00 am,the values are 0.1 ℃,5.2%,respectively.The effect on air temperature and relative humidity generally continued until the end of sprinkler irrigation 20 min.
