杂交中稻头季稻花期阴雨下产量与再生稻产量的关系
YieId of Main Crop Rice under Continuous Overcast and Raining during FIowering Stage and Its ReIation with YieId of Ratooning Crop in MiddIe -season Hybrid Rice
摘要
Abstract
In order to determine the remedial function of ratooning rice for rain disaster,20 approved middle -season hy-brid rice varieties were used to study the main crop rice yield under continuous overcast and raining during flowering stage and its relation with yield of ratooning rice under nitrogen application or no nitrogen application.The results showed that there were significant difference between the yields of main crop and ratooning crop with or without nitrogen application. There was significantly negative correlation between the yields of main crop rice and ratooning rice.The yields of main crop and ratooning rice were significantly increased by nitrogen application.The varieties with higher yield under no nitrogen application were more increased under nitrogen application.The yield of ratooning rice can serve as the supplement of the main crop rice in continuous overcast and raining days during flowering stage.This study provided the theoretical basis and technical support for the anti reverse technology of middle -season hybrid rice and ratooning rice.关键词
