摘要:
以黄花补血草为试材，设置0.5、10、15、20、25、30 mm 6个灌溉处理，以0 mm灌溉处理为对照，研究了不同灌溉量对黄花补血草生物量的影响。结果表明：1）黄花补血草密度随灌溉量的增加呈先上升后下降的趋势。2）单株地上部鲜质量在0.5 mm灌溉处理下最低，干质量在10 mm灌溉处理下最低，二者均在20 mm灌溉处理下最高，其含水量整体呈上升的趋势。3）地下部鲜质量在25 mm灌溉处理最大，显著高于对照和其它处理，在15、20、25 mm灌溉处理下的干质量显著高于对照与10 mm灌溉处理。4）在高灌溉（25 mm和30 mm）处理下，黄花补血草株高及冠幅均与对照之间存在显著性差异。
Abstract:
Limonium aureum was used as experimental material,the effect of the different irrigation quota on the biomass of Limonium aureum was studied under the six total irrigation treatments（0.5,10,15,20,25,30 mm),with the treatment of 0 mm irrigation as control.The results showed that,1)With the increasing irrigation quota,the density of Limonium aureum increased firstly and then decreased.2)The aboveground fresh and dry weight of Limonium aureum both reached the lowest point under the 10 mm irrigation treatment,and reached the highest point under the 20 mm irrigation treatment,and the water content of aboveground showed an increased trend on the whole.3)The fresh weight of underground reached the highest point under the 25 mm irrigation treatment,which was significantly higher than the control and the other irrigation treatments.The dry weight of underground under the 15,20,25 mm irrigation treatment was significantly higher than the 10 mm irrigation treatment and control.4)Under the high irrigation quota treatment（25 mm and 30 mm),there were significant differences between the plant height and canopy with the control.
