摘要:
用盘装佛甲草设计制作8个浇灌试样,在福建省厦门市的夏季典型气候下,对比实测不同浇灌方式对试样水分蒸发量、浇灌耗水量及基质温度的影响.结论表明:在盘装佛甲草每日间歇裸浇1次的情况下,浇灌时间点对其日水分蒸发量影响不大,但对其逐时水分蒸发量有时序影响;在吸液材料持续浇灌情况下,吸液材料和吸液方式对盘装佛甲草的日水分蒸发量和逐时水分蒸发量均影响不大;与每日裸浇1次的间歇浇灌相比,在夏季连续高温下,利用吸液材料持续灌溉至少可节约用水18%且可显著降低基质温度均值和振幅值.此外,在持续高温条件下,盘装佛甲草3 d不浇灌,其日水分蒸发量将显著降低,6 d不浇灌,其日水分蒸发量将接近于零.
Abstract:
8 irrigation samples of palletized Sedum lineare Thunb were carried out, and the effects of different irrigation methods on the water evaporation, water consumption and substrate temperature of the samples were measured and compared under the typical summer climate in Xiamen City. The results show that: under the condition of intermittent bare irrigation once a day for palletized Sedum lineare Thunb, the time point of irrigation has little effect on its daily water evaporation, but has a time sequence effect on its hourly water evaporation. Under the condition of continuous irrigation with water suction material, the material and method for water suction has little influence on the daily and hourly water evaporation; comparing with the intermittent irrigation with bare irrigation once a day, on the continuous high temperature days in summer, continuous irrigation with suction material can save 18% of water consumption at least per day in summer and significantly reduce the mean value and amplitude value of substrate temperature; for 3 days without irrigation, its daily water evaporation decreases significantly; for 6 days without irrigation, its daily water evaporation is close to zero.
