以杂交水稻深优9586为材料,采用盆栽试验,通过自制增氧装置增加灌溉水中的氧容量,研究增氧灌溉对杂交水稻根系生长特征及活力的影响。结果表明：与CK处理相比,增氧灌溉处理水稻的根总表面积、总体积、平均根粗和根尖数均具有明显优势;随着生育期的推进,各增氧处理的根系干物质积累不断增加,且明显优于CK处理,但是根冠比整体呈降低趋势;同时,所有增氧处理水稻的根系TTC还原强度均明显强于CK处理,说明增氧灌溉处理能明显提高根系活力。

To explore the effects of oxygation on rice root growth, taking hybrid rice Shenyou 9586 as the material, the research conducted the pot experiment with self-made oxygen-enriching equipment which could increase the oxygen content of irrigation water, so as to study the impact of oxygation on root growth characteristics and root activity of hybrid rice. The results showed that the root surface area, total volume, mean root diameter and root number of oxygation treatments had significant advantages compared to CK treatment. With the advance of growth period, the root dry matter accumulation of o...
