中文摘要:
      通过温室小区试验,研究了加气灌溉对土壤生境因子的影响。结果表明:与对照处理相比,加气灌溉降低了4.0%的平均土壤含水量,增加了1.5%的平均土壤O2含量、3.4%的平均土壤温度、3.7%的平均土壤NO-3—N含量及1.0%的平均土壤NH+4—N含量。加气灌溉对试验中观测的土壤生境因子的影响不显著(p>0.05),但土壤生境因子的微小改变可能会大幅改变土壤的环境效应和作物产量及品质,值得进一步研究。该研究对深入研究和客观评价加气灌溉技术具有重要意义。
英文摘要:
      Plot trials in greenhouse were conducted to study the effects of aerated irrigation on soil habitat factors.The results showed that aerated irrigation decreased the mean value of soil moisture by 4.0%, compared to the CK. But, aerated irrigation increased the mean value of soil oxygen content, soil temperature, NO-3—N content and NH+4—N content by 1.5%, 3.4%, 3.7% and 1.0%, respectively, compared to the CK. Effects of aerated irrigation on soil habitat factors in our study were not significant (p>0.05). But the small changes of soil habitat factors maybe lead to great changes of soil environmental effects and the crop yield and quality. The study has important implications for in-depth research and objective evaluation of aerated irrigation techniques.
