作物根际增氧栽培研究进展

Research Progress of Grop Rhizosphere Aeration Cultivation

根系在植物的生命活动中具有重要作用,不仅支持植物生长,更是植物吸收水分和养分的重要器官。近几年土壤板结日趋严重,通透性差,限制了根系生长,从而影响作物生长。土壤含氧量是决定作物能否正常生长发育的关键因子。一些研究显示,采用合理的增氧措施,可以有效提高作物根际氧气含量,提高土壤肥力,有利于改善作物产量、提高作物品质。文中总结了目前生产上一些常规增氧方法及增氧对植株生长发育的影响,旨在为根际增氧栽培的深入研究奠定基础。

Root system plays an important role in plant life activities,which not only supports plant growth,but also serves as an important organ for plants to absorb water and nutrients.In recent years,soil compaction becomes more and more serious and permeability is poor,which limits the growth of roots and affects the growth of crops.Soil oxygen content is the key factor to determine the normal growth and development of crops.Some researches showed that using reasonable measures of increasing oxygen can effectively increase the oxygen content in rhizosphere,improve soil fertility and improve crop yield and quality.In this paper,some conventional methods of increasing oxygen in production and the effect of increasing oxygen on plant growth and development were summarized,in order to lay a foundation for the in-depth study of rhizosphere aeration cultivation.
