| 摘 要： | 通过盆栽试验,对不同土壤水分条件下（土壤含水量分别为田间持水量的80%、60%、45%、35%）1年生大红袍花椒生长及蒸腾耗水特性进行了研究。结果表明：不同土壤水分条件下,大红袍花椒耗水量差异很大,土壤含水量为田间持水量的80%、60%、45%、35%时,5~8月份花椒幼苗的耗水量分别为10.05、5.97、5.39、3.37 kg;土壤水分供应充足有利于花椒地上部分的生长,干旱胁迫则有利于花椒根系的生长。 |

| Abstract: | Zanthoxylum bungeanum was cultivated in pots on different soil water contents(soil water contents are respectively 80%,65%,45%,35% of field capacity).The results showed that the water consumptions of Z.bungeanum on different soil water contents above were respectively 10.05,5.97,5.39 and 3.37 kg respectively in the condition of relative soil water content 80%,65%,45%,35% from May to August.Adequate soil water improves the above-ground growth of Z.bungeanum and water stress improves root system. |
| Keywords: | Zanthoxylum bungeanum soil water content water consumption biomass |
