加氧灌溉对烟草生长影响规律的研究

加氧灌溉能很好地解决常规灌溉中“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。通的对烟草进行机械加氧灌溉、化学加氧灌溉及常规对照三个处理进行试验研究,通过检测并分析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,两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。

Study on the influence of tobacco growth by oxygation

Oxygation can solve well 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 were studied by dealt with three processing, machinery oxygation, chemical oxygation and conventional irrigation. The related index of root and agronomic trait were tested and analysed. The two oxygations can significantly promote the growth of root, the increase of leaf area, and improvement the yield of tobacco. Compared with the conventional treatment, mechanical oxygation is conducive to the root deeper than chemical oxygation, but chemical oxygation is conducive to distribute nutrient to the ground plant.
