施用不同复合有机肥对烤烟光合特性及品质的影响

摘要

采用田间试验,研究不同复合有机肥对烤烟光合特性及品质的影响.结果表明:复合有机肥和化肥配施的效果明显优于单纯施用化肥,它不仅可以促进烟株光合作用强度,减小光合速率下降的速度,而且有利于后期烟叶中碳水化合物的增加和积累.提高烤烟的品质.%The effects of different compound organic fertilizers on photosynthetic characteristics and quality of tobacco were researched by using field experiments. The results showed that effect of combined application of compound organic fertilizer and chemical fertilizer was obviously better than that of application of pure chemical fertilizer, which showed as follows: promoting photosynthetic intensity of tobacco plant, reducing decreasing velocity of photosynthetic rate, bring advantage to the increase and accumulation of carbohydrate in tobacco leaf in later period, and enhancing the quality of tobacco.
