| 摘 要： | 以稀植大穗型品种辽单145为材料,研究不同化控剂种类和喷施时期对辽单145光合特性、形态指标和产量的影响。结果表明,喷施化控剂提高了辽单145灌浆期穗位叶光合速率和叶面积指数。6展叶期和9展叶期,康丰利化控剂处理下辽单145叶面积指数和穗位叶光合速率分别达到最高值。与对照相比,喷施化控剂降低了辽单145株高和穗位高。喷施金得乐化控剂增加了辽单145茎粗,缩短其茎基部节间长度。测产结果表明,在6展叶期喷施康美化控剂可以显著提高辽单145产量。

| Abstract: | Effects of different chemical regulators and spraying periods on photosynthetic characters, morphological indexes and yield of thin planting, big ear-type hybrid maize Liaodan145 were studied. The results showed that LAI and photosynthetic rate of ear leaf were all significant increased by spraying chemical regulators at filling stage. LAI and photosynthetic rate of ear leaf reached the highest values by spraying Kang Fengli at leafage 6 and 9 respectively. Compared with CK, plant height and ear height of Liaodan145 were reduced by spraying chemical regulators. Stem diameter of Liaodan145 was increased and internode length of that was shortened at Jin Dele treatment. Results of yield data showed that the yield of Liaodan145 was significant improved by spraying Kang Mei at leafage 6. |
