加氧灌溉能较好解决常规灌溉中“水氧矛盾”的问题,从而实现低水肥、高吸收、高产量、高品质的目标.通过对烟草进行机械加氧灌溉、化学加氧灌溉及常规对照3个处理的试验研究,检测并分析了烟草根系和农艺性状的相关指标,得出相对于常规对照处理,2种加氧灌溉处理均显著促进根系生长,增大叶面积,提高烟叶产量.机械加氧灌溉比化学加氧灌溉更有利于根系的扎深,化学加氧灌溉比机械加氧灌溉更有利于营养物质向地面植株的分配.

Oxygation can solve the problem of ＂contradiction between water and oxygen＂ of the conventional irrigation to realize goals of low fertilization, high absorption, high yield and high quality. In this paper, tobacco is studied by dealing with three processing, machinery oxygation, chemical oxygation and conventional irrigation. The related index of root and agronomic traits are tested and analyzed. The two oxygations can significantly promote the growth of roots, the increase of leaf areas, and improve the yield of tobacco. Compared with the c...
