Abstract
By using surface drip irrigation, a field experiment including nine drip irrigation and fertigation treatments was carried out, with non-irrigation and non-fertilization as control (CK), to evaluate the integrative effects of water and nitrogen management on the increment of diameter, tree height, and stem volume, and the total nitrogen content in the 0-60 cm soil layer in the poplar (Populus ×euramericana cv. 'Guariento') plantations. There were three irrigation levels (irrigation was initiated when soil water potentials at 20 cm soil depth reached -75, -50 and -25 kPa) and three levels of nitrogen addition (150, 300 and 450 g·tree-1·a-1). Surface drip irrigation and fertigation treatments were applied in the gro-wing seasons of 2012 and 2013. The results showed that the combined treatments of water and nitrogen addition significantly increased growth and stem volume of the poplar plantation. In the first year of the experiment, the annual increment of stem volume was 11.54 m3·hm-2·a-1 in high water and high fertilizer treatment (soil water potentials of -25 kPa + nitrogen addition of 450 g·tree-1·a-1), which was 44.1% higher than that in the CK (8.01 m3·hm-2·a-1). In the second year, the annual increment of stem volume was 27.85 m3·hm-2·a-1 in medium water and high fertilizer treatment (soil water potentials of -50 kPa + nitrogen addition of 450 g·tree-1·a-1), being 36.0% higher than that in CK (20.48 m3·hm-2·a-1). The successive combined treatments signi-ficantly increased the total N content in the 0-20 cm soil layer, with total N content of each soil layer in the first and second year of the experiment being 12.3%-59.4% and 71.1%-81.1% higher than CK, respectively. The increments of diameter and tree height were significantly positively correlated with soil total N content. Nitrogen addition and the interactive effects of water and nitrogen addition significantly affected the diameter and height of trees and soil N content, while irrigation showed no significant effect. In conclusion, the combined drip irrigation and fertigation significantly increased growth and stem volume of the poplar plantation by promoting the soil fertility especially nitrogen availability in the topsoil.

g·tree<sup>-1</sup>·a<sup>-1</sup>)组合,于2012和2013年2个生长季的滴灌水氮耦合措施后,研究耦合措施对欧美108杨林木胸径、树高和蓄积量的年增量及0～60 cm土层全氮含量的影响.结果表明: 水氮耦合措施可显著促进108杨林木生长并有效提高林地生产力,耦合措施第一年,9个耦合处理中高水高肥处理(土壤水势-25 kPa+施N量450 g·tree<sup>-1</sup>·a<sup>-1</sup>)使108杨蓄积年增量达到11.54 m<sup>3</sup>·hm<sup>-2</sup>·a<sup>-1</sup>,相比CK的8.01 m<sup>3</sup>·hm<sup>-2</sup>·a<sup>-1</sup>提高了44.1%,耦合措施第二年,中水高肥处理(土壤水势-50 kPa+施N量450 g·tree<sup>-1</sup>·a<sup>-1</sup>)使108杨蓄积年增量达到27.85 m<sup>3</sup>·hm<sup>-2</sup>·a<sup>-1</sup>,较CK的20.48 m<sup>3</sup>·hm<sup>-2</sup>·a<sup>-1</sup>提高36.0%.连续的水氮耦合措施显著提高了林地0～20 cm土层全N含量,耦合措施第一和第二年高水高肥处理各土层全N含量分别比CK高出12.3%～59.4%和71.1%～81.1%.108杨胸径和树高增量与土壤全N含量呈显著正相关,施N水平和水氮交互作用对林木生长和土壤全N含量具有显著的影响,而灌溉水平的影响不显著.综合表明,滴灌水氮耦合措施可通过改善林地土壤肥力,尤其是浅土层全氮含量来有效促进林木生长并提高林地生产力.</AbstractText></OtherAbstract><KeywordList
