摘要
本文对深灌水控制水稻无效分蘖所需的灌水深度和时间进行了研究。试验结果表明:采用深灌水控制水稻无效分蘖时,首先应注意是掌握在分蘖芽分化发育过程中对外界环境的敏感期进行;其次是灌水深度须完全淹没欲控分蘖芽所着生节上的母茎叶鞘:再次是每控制一个分蘖芽,处理时间应不少于一个叶龄期。
The depth and the time of deep water treatment were investigated in the experiments of inhibiting the ineffective tiller in rice plant. The results showed that the measure should be taken at the stage sensitive to environmental conditions. Water level should be raised to the depth completely submerging the leaf sheath in which the tiller bud need to be controlled. The period of a leaf emergence would be needed to controll a tiller bud.
