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。
In this paper, the irrigation depth and time needed to control inefficient tillering of rice in deep irrigation were studied. The results showed that: when using deep irrigation to control invalid tillers, we should first pay attention to grasping the sensitive period to the external environment during the differentiation and development of tiller buds. Secondly, the depth of irrigation must be completely submerged on the node Stem leaf sheath: Once again, each control of a tillering buds, processing time should not be less than one leaf age.
