摘  要：
采用盆栽试验,设常规灌溉、分根区交替灌溉、分根区固定灌溉3种处理在沈阳农业大学网室内对非洲菊进行了研究,结果表明:同一时期,对3种灌溉处理下植株叶片叶绿素含量、地上干物质量进行比较结果为:分根区交替灌溉>常规灌溉>分根区固定灌溉;对可溶性糖含量进行比较结果为分根区固定灌溉的含量每个时期都小于全根灌溉,交替灌溉在8月和10月时小于常规灌大于固定灌,12月时大于常规灌,交替灌溉的含量随气温的降低逐渐增加,12月比8月增加了36.49%,达到了显著性差异;对3种灌溉处理下作物的养分利用率进行比较结果为分根区交替灌溉>常规灌溉>固定灌溉,并达到了显著性水平。

摘  要：
Pot experiment was introduced to study Gerbera in net room of Shenyang Agriculture University.The samples including alternative partial root-zone irrigation;fixed partial root-zone irrigation;conventional irrigation.The results showed that in the same period,the content of the chlorophyll、the ground dry weight in Gerbera leaves were changed in the sequence: alternative partial root-zone irrigation>conventional irrigation>fixed partial root-zone irrigation;the content of soluble sugar of Gerbera were changed in the sequence: conventional irrigation>fixed partial root-zone irrigation,in August and October conventional irrigation>alternative partial root-zone irrigation> fixed partial root-zone irrigation,in December alternative partial root-zone irrigation>conventional irrigation,as the temperature decrease,the content of soluble sugar gradually increased,the content in December than in august increased by 36.94%.the nutrient utilization of Gerbera were changed in the sequence:alternative partial root-zone irrigation>conventional irrigation>fixed partial root-zone irrigation,and it reach the statistical significant.
