【摘要】：水、肥、气、热是保障土壤肥力的四大要素,传统的灌溉方式往往忽视了气这一重要因素。土壤通气性不足,四个因素之间的平衡被打破,土壤理化性质变差,对作物生长造成不利影响,进而引起减产。良好的土壤通气性是作物正常生长发育的保证。加氧灌溉通过采用合理的方法改善土壤通气状况,协调土壤四大要素之间的关系,提高土壤肥力,满足作物生长的需要。研究表明,加氧灌溉可提高作物产量、改善作物品质。本文从根区低氧胁迫的影响分析入手,评述了土壤通气性的量化指标、测算方法和控制标准,综述了加氧灌溉技术及其应用,总结了加氧灌溉研究中存在的问题,探讨了加氧灌溉对土壤通气性的改善作用,提出了加氧灌溉与土壤通气性研究展望,以期为今后的研究提供参考。
[Abstract]:Water, fertilizer, gas and heat are the four main factors to ensure soil fertility. Traditional irrigation methods often ignore the important factor of gas. The balance between the four factors was broken, and the physical and chemical properties of the soil became worse, which had an adverse effect on crop growth and then led to the reduction of production. Good soil aeration is the guarantee of crop normal growth and development. By adopting reasonable methods to improve soil aeration, to coordinate the relationship among the four elements of soil, to improve soil fertility and to meet the needs of crop growth. The results show that oxygen irrigation can increase crop yield and improve crop quality. Based on the analysis of the effects of root zone hypoxia stress, this paper reviews the quantitative indexes, measurement methods and control standards of soil aeration, summarizes the oxygen-added irrigation technology and its application, and summarizes the existing problems in the research of oxygen-added irrigation. In this paper, the effect of oxygenated irrigation on soil aeration was discussed, and the prospect of aerobic irrigation and soil aeration was put forward in order to provide reference for future research.
