摘要
以3年生相同生境西洋樱桃品种"红灯"为试材,通过测定土壤含水量、茎流量、叶片水势、蒸腾速率等指标,研究同一樱桃在不同栽培条件下水状态参数的日变化。结果表明:土壤含水量无论在空间还是时间上,都是随深度和时间的推移而递减,茎流量呈现倒"U"字型曲线,叶片水势呈现"V"字型曲线,蒸腾速率在晴天呈现双峰曲线,土壤含水量、茎流量、叶片水势和蒸腾速率有明显的相关性。
Taking the same type of three-year-old P. avium L. cultivars cv. ＇ Hongdeng＇ as material, the soil water content, stem velocity,leaf water potential and transpiration rate in the same environment were measured, the diurnal variation of water of same plant under different cultivation condition was studied. The results showed that the soil water content decreased both in the spatial distribution and vertical distribution. The daily variation of stem velocity was kurtosis of U-inverse. The daily variation of leaf water potential was of V-type. The diurnal change curves of transpiration rate were of the midday-depression type in sunny day. Correlation analysis showed that soil water content, stem velocity and leaf water potential had a remarkable correlation with transpiration rate.
