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%。
In order to find out the application effect of photosynthesis synergist on the early hybrid rice, the experiment was conducted in Lingyun Teaching Practice Base of Hunan Agricultural University in Lingliang County Tomb Liangyou 268 for the material, carried out “leaf edge ” field test. The results showed that spraying photosynthesis synergist at early tillering stage increased the chlorophyll content, photosynthetic rate, transpiration rate and yield per unit area of early rice. Photosynthesis synergist treatment photosynthesis rate, chlorophyll content of two pilot were significantly higher than the control, the actual output of agricultural output 8.54% larger than the control, Hengyang point yield 10.67% more than the control.
