摘要
以豫麦49-198为供试冬小麦品种,研究了大田无机肥与有机肥配施对旗叶光合性状及子粒产量的影响.结果表明,单施有机肥或无机肥与有机肥配施均能延缓旗叶后期光合速率下降,延长叶片功能期,有利于后期光合物质的积累与转运.与不施氮肥(对照)比较,单施有机肥或无机肥与有机肥配施均能提高豫麦49-198子粒产量,并以单施牛粪处理产量最高,差异达显著水平.通过分析各处理子粒产量构成因素发现,不同施肥处理产量的提高主要因该处理提高了产量三要素中的某些因子,如尿素与牛粪配施主要通过增加单穗粒数来实现产量提高.综合以上分析,单施有机肥或无机肥与有机肥配施均能提高旗叶后期光合速率和增加子粒产量.
To investigate the application effects of inorganic nitrogen （N） combined with organic manure on photosynthesis and yields of winter wheat, a wheat cultivar （Yumai 49 - 198） was used in field experiments. The results showed that application of both single organic manure and urea combined with organic manure could increase net photosynthesis of flag leaf and could prolong the physiological function of wheat leaves, which would make for accumulation and transportation of photosynthesis matter in the later stage. Comparing with no N application, each fertilizer treatment increased grain yield of winter wheat, especially application of single cattle manure with 7.5 percent of yield increase. In addition, there are differences in yield components of Yumai 49-198 such as the treatment of urea combined with cattle manure that mainly enhanced grain number per spike to increase yield. On the whole in this experiment, the single manure or urea combined with manure treatment could increase net photosynthesis in the later flag leaves and increase the grain yield of Yumai 49 - 198.
