摘　　要：In order to explore the application effect of Yezhiyuan in early hybrid rice,Liangliangyou No.211 and Lingliangyou No.268 were tested in a teaching base in Hunan Agricultural University and Xidu Town, Hengyang County, with Yezhiyuan.The test results showed that the application of photosynthesis synergist in later tillering stage would increase the content of chlorophyll of functional leaf and photosynthetic rate, reduce transpiration rate and enhance yield per unit area. With Yezhiyuan applied, both of photosynthetic rate and chlorophyll content kept higher compared with control group in two experimental sites, and practical yield in Hunan Agricultural University grew 8.54% higher compared with control group, and 10.67%in Hengyang.为探明"叶之缘"光合作用增效剂在杂交早稻上的应用效果,2012年分别在湖南农业大学耘园教学实习基地以陵两优211为材料,在衡阳县西渡镇以陵两优268为材料,开展了"叶之缘"田间试验。结果表明,在早稻分蘖末期喷施光合作用增效剂,可增加早稻功能叶叶绿素含量、提高光合速率、降低蒸腾速率、增加单位面积产量。光合作用增效剂处理下光合速率、叶绿素含量两试点均显著高于对照,实际产量农大点比对照增产8.54%,衡阳点比对照增产10.67%。
