不同施肥组合对小麦光合性状及产量的影响

摘要

The effects of different fertilization combinations on wheat photosynthetic characters and yield were studied in this paper .The results indicated that all the fertilization treatments significantly increased the chlorophyll content , photosynthetic rate and leaf area index of flag leaf .The photosynthetic rate was the high-est under the treatment of combined application of pig manure compost and N -P-K fertilizer ( T5 ) , which increased by 17.0%compared to the contrast;and then were the T2 and T3 treatments, which increased by 14 .0%and 11 .0% respectively .The T5 treatment increased all the tested indexes more significantly com-pared with the other treatments .T5 treatment could significantly increase the grain number per spike and ob-tain the highest yield .%研究了不同施肥组合对冬小麦光合性状及产量的影响。结果表明：各施肥处理冬小麦旗叶叶绿素含量、光合速率、叶面积系数比对照都显著提高，其中猪粪堆肥有机无机复混肥（ T5）处理光合速率最高，平均比对照提高17．0％，其次是T2、T3，分别比对照提高14．0％、11．0％；与其它处理相比，T5处理各项指标提高最为显著；T5处理可以显著提高小麦的穗粒数，产量最高。
