| 摘 要： | 采用大田试验研究养殖废水灌溉对作物-土壤系统各因子的影响。结果表明,灌水定额为900 m3/hm2有利于产量的增加,灌水定额为600 m3/hm2有利于水分利用效率提高。冬小麦叶水势随生育阶段的推移而减小,养殖废水处理的叶水势较清水处理的小。表层0~40 cm为水分交替变化的敏感土层,随深度的增加,变化幅度减小。 |
| 关 键 词： | 养殖废水灌溉 生长发育指标 叶水势 土水势 |

| Abstract: | Field trials were conducted to study the influence of livestock wastewater irrigation on crop-soil system.The results showed that irrigation quota of 900 m3/hm2 is beneficial to yield increasing,and irrigation quota of 600 m3/hm2 is beneficial to water use efficiency increasing.Leaf water potential decreases with advancing growth stage.And the leaf water potential is less than clear water control treatment.The soil layer of 0~40 cm is the sensitive layer of soil water alternating changing.And the change of ... |
