观察了 6个再生稻品种和 6个再生稻氮肥施用量的产量与伤流量变化动态 ,结果看出 ,再生季产量与头季成熟期及再生季齐穗期的伤流量呈极显著正相关 ,再生穗数与头季成熟期的伤流量呈极显著正相关 ,与再生季齐穗期的伤流量呈显著正相关。表明 :水稻再生力与根系后期的机能密切相关 ,头季成熟期的伤流量 ,可作为诊断再生力、筛选再生稻品种的重要指标
The results showed that there was a significant positive correlation between the grain yield and the traumatic flow in the mature season of the first season and the heading stage of the regeneration season. There was a significant positive correlation between the number of regenerated spikes and the amount of wounds in the first season, and the correlation between the number of spikes and the amount of wounds at the heading stage. The results showed that the rice regenerative ability was closely related to the function of the late root system and the injury flow during the first season could be used as an important index for the diagnosis of regenerative ability and selection of ratoon rice varieties
