中文摘要:
      为探求光碳核肥对谷子光合特性、生理生化性能及产量性状的影响。以‘豫谷28’为试验材料,分析了开花期谷子各项生育指标对不同光碳核肥浓度处理的响应。试验共设4个处理:N0不喷施光碳核肥,设为对照(CK);N1、N2和N3喷施光碳核肥浓度分别为2.25、4.5和6.75 L/hm2 。结果表明,增施光碳核肥后,N1、N2和N3浓度处理下谷子光合特性和生理生化性能及产量均较对照(CK)显著增加,且峰值均出现在N2浓度处理下。其中在N2浓度处理下叶绿素a、叶绿素b、叶绿素(a+b)含量分别较对照(CK)增加了41.8%、53.8%和48.2%,光合速率、胞间CO2浓度、气孔导度和水分利用效率分别提高了30.9%、76.5%、66.7%和38.7%。可溶性糖和可溶性蛋白质含量分别较对照(CK)增加了95.1%和5.4倍;SOD、POD和CAT活性分别较对照(CK)提高了26.7%、86.8%和90.0%;重心高度较对照(CK)降低了8.3%,弯折力和抗倒指数则分别增加了56.5%和69.2%;穗长、穗粒质量、千粒质量、地上生物量和亩产量分别较对照(CK)提高了13.7%、60.4%、5.3%、58.1%和9.2%。综上所述,增施适宜浓度光碳核肥对于增强谷子的光合作用、改善其生理生化性能及提高产量具有重要意义。
英文摘要:
      To investigate the effects of CO2 capture agent on photosynthetic characteristics, physiological and biochemical indices and yield traits of foxtail millet, the authors used‘Yugu 28’as experimental material and analyzed the indices under different concentrations of CO2 capture agent at flowering stage. In this experiment, 4 treatments were set up: N0 was no spraying of CO2 capture agent (CK), the concentration of N1, N2 and N3 was 2.25, 4.50 and 6.75 L/hm2, respectively. The results showed that photosynthetic characteristics, physiological and biochemical indices and yield traits of millet were significantly higher than those of control under N1, N2 and N3, and all peak values appeared under N2. Under N2, compared with CK, the contents of chlorophyll a, chlorophyll b and chlorophyll (a+b) increased by 41.8%, 53.8% and 48.2%, respectively; the photosynthetic rate, intercellular CO2, stomatal conductance and water use efficiency increased by 30.9% , 76.5% , 66.7% and 38.7% compared with that of CK, respectively; the soluble sugar and soluble protein content increased by 95.1% and 5.4- fold, respectively; the activity of SOD, POD and CAT increased by 26.7%, 86.8% and 90.0%, respectively; while the height of gravitational center decreased by 8.3%, and the bending force and culm lodging resistant index increased by 56.5% and 69.2%, respectively; the spike length, panicle grain mass, thousand grain mass, aboveground biomass and yield increased by 13.7%, 60.4%, 5.3%, 58.1% and 9.2% , respectively. As suggested above, it is of great importance to enhance photosynthesis, improve physiological and biochemical indices and increase yield of millet with applying certain concentrations of CO2 capture agent.
