Preliminary Research of Water and Salt Movement in Soil Growing Fragrant Pear under Drip Irrigation
摘要
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.关键词
