| 摘要：为了探讨水溶性肥料兴欣安利素和兴欣富利素对水稻和小麦产量调控，以水稻武运粳23号、小麦扬麦16号为材料，在其后期喷施1次和2次，分析其叶绿素变化趋势，及其产量。结果表明，对于小麦在抽穗扬花期喷施液体叶面肥，均明显提高旗叶叶绿素含量，结合多菌灵喷施效果会提升。而对水稻叶绿素的调控是在破口期喷施液体叶面肥，均不同程度地明显提高旗叶叶绿素含量，尤其是高浓度的叶面肥处理。在产量方面，小麦所有肥料处理的千粒重含量均明显高于对照。就叶面肥兴欣安利素来说，高浓度处理的小麦籽粒千粒重显著高于低浓度处理的。结合多菌灵喷施小麦籽粒的千粒重增加。从产量上看，喷施一次，低浓度的肥料喷施下小麦籽粒产量上升，但是比对照差异不显著。高度肥料喷施下，小麦籽粒产量显著上升。但不同肥料间差异不显著。喷施两次，所有肥料处理下小麦籽粒产量均显著上升。对于水稻，所有肥料处理的千粒重均不同程度的明显高于对照，肥料间比较无明显差异。综上所述，含氨基酸水溶肥料液体叶面肥兴欣安利素和含腐殖酸水溶肥料液体叶面肥兴欣富利素在小麦扬花期和齐穗期及水稻破口期和齐穗期喷施均可以明显提高叶片叶绿素含量，抗早衰，从而提高稻麦千粒重和产量。30128 毕业论文关键词: 叶面肥，水稻，小麦，喷施，叶绿素，产量 Different water soluble fertilizer was studied in the anti -pre mature aging, production control and mechanism of the rice wheat in Nanking hills Abstract: In order to explore the water soluble fertilizer and xing xin xing xin amway futura element for rice and wheat production regulation, to rice wuyunjing, 16 to 23, of young wheat materials, spraying late in the 1 and 2 times, analyze its chlorophyll change trend, and its production. The results showed that the chlorophyll content of the flagellate was significantly increased in wheat, and the effect of the combination of the polymyronic spray was improved. For control of rice chlorophyll is spraying liquid foliar fertilizer of the break period, are obviously improved in different degrees of the flag leaf chlorophyll content, especially the high concentration of foliar fertilizer treatment. In terms of yield, the amount of grain in the wheat fertilizer was significantly higher than the control. In amway, the high concentration of wheat grains is significantly higher than the low concentration. The grain weight of wheat grain was increased by the combination of the polymyronic spray. On production, the yield of wheat grains was increased with low concentration of fertilizer, but not by comparison. The yield of wheat grains increased significantly under high fertilizer spray. But the differences between different fertilizers were not significant. The output of wheat seed grains increased significantly with all fertilizer treatment. In the case of rice, the weight of all fertilizer treatment was significantly higher than that of comparison, and there was no obvious difference between the fertilizer. To sum up, water soluble fertilizer containing amino acid liquid foliar fertilizer xing xin amway and liquid foliar fertilizer containing humic acid water soluble fertilizer xing xin young rich element in wheat flowering and full panicle stage and rice crevasse and full panicle stage spraying can obviously increase the chlorophyll content, premature aging resistance, thus improve the thousand seed weight and yield of rice and wheat.
