| 摘 要： | 为了探究半干旱地区苹果树的需水规律,以封闭果树根域土壤为试材,防止地面蒸发,采用定期连续测定土壤含水量的方法来测算果树的蒸腾量。结果表明：9年生矮化中间砧果树吸收土壤水分的主要垂直空间在0~60 cm土层,60 cm以下土层含水量变化不明显。果树秋季蒸腾耗水量为134 kg/棵,春季萌芽到花期,蒸腾耗水量为104 kg/棵。因此,在进行田间管理时,以0~60 cm湿润层确定节水灌溉较为科学。

| Abstract: | In order to study the water requirement law of apple trees in semi-arid areas, the soil in the closed fruit tree root region was used as test material to prevent ground evaporation, and the soil moisture content was measured regularly and continuously to estimate the transpiration of fruit trees. The results showed that the main vertical space of soil water absorption of 9-year dwarf interstock fruit tree was 0-60 cm soil layer, and the moisture content of soil layer below 60 cm had no obvious change. The transpiration water consumption of fruit trees was 134 kg/tree in autumn and 104 kg/tree from budding to flowering stage in spring. Therefore, in field management, it is more scientific to determine water-saving irrigation in 0-60 cm wet layer. |
