为探究免耕半固态播种模式对水稻剑叶生理及光合特性的影响。通过设计翻耕半固态直播(FZ)、免耕半固态直播(MZ)、水稻插秧(YZ)和传统撒直播(CK)的田间对比试验,研究了不同栽培模式下水稻剑叶生理和光合特性的特征。与CK处理相比, 2016年早稻中早39、湘早籼45号FZ、MZ处理的剑叶SPAD值在乳熟期-成熟期显著高于CK处理, 2017中早39的FZ、MZ、YZ处理较CK处理早稻与晚稻增幅分别为0.85% ~ 15.41%,1.60% ~ 13.04%,且在齐穗+ 28 d和齐穗+ 35 d均达到显著性差异。FZ、MZ和YZ较CK处理水稻剑叶POD和SOD活性在齐穗后均呈增加趋势,而MDA呈降低趋势,其中中早39各时期MDA含量的均值平均降幅分别为13.35%,9. 35...

In order to explore the effects of no tillage and semi-solid sowing mode on the physiological and photosynthetic characteristics of flag leaf of rice. Field comparative experiments were designed to study the physiological and photosynthetic characteristics of flag leaf of rice under different cultivation modes, including tillage semisolid direct seeding(FZ),no tillage semi-solid direct seeding(MZ), rice transplanting(YZ)and traditional direct seeding(CK). In 2016, the flag leaf SPAD values of FZ and MZ treatments of early rice Zhongzao 39 and Xiangzaoxian 45 were significantly higher than thos...
