摘要:
研究香梨滴灌条件下土壤水盐分布特征，可为香梨合理水盐调控灌溉技术提供参考。对株行距为3 m×5 m、树龄4 a的香梨分别进行150，200，250，300 mm灌溉定额滴灌试验，测定香梨生育期土壤剖面水分和盐分分布特性。结果表明：香梨生育期内，150，200 mm和250 mm灌溉定额使香梨根区土壤处于水分胁迫状态，不能满足香梨对水分的需求，300 mm灌溉定额在香梨生育期具有洗盐效果，可作为株行距为3 m×5 m、树龄4 a的香梨节水控盐滴灌灌溉定额。进行香梨节水灌溉时，需考虑滴灌灌溉定额对土壤水盐分布的影响。
Abstract:
Distribution features of the soil water and salt under drip irrigation were studied to offer a reference for reasonable irrigation technology for the purpose of the adjustment and control of water and salt in soil growing fragrant pear. The distribution features of soil water and salt were analyzed based on the field experiment of the fragrant pear with planting space were 3 m×5 m, 4 years old, under the drip irrigation quota of 150, 200, 250, 300 mm, respectively. Results showed that soil water content could’t meet fragrant pear demand of moisture and appear water stress under 150, 200, 250 mm irrigation quota in the fragrant pear growth period. Drip irrigation quota of 300 mm had the effect to regulate and control soil water and salt, which was regarded as the reasonable drip irrigation quota and technical parameters for 4-year-old fragrant pear planted according to space of 3 m×5 m. The drip irrigation quota should be considered when the soil water and salt distribution features are adjusted under water saving irrigation for young fragrant pear.
