摘　　要：以杨—麦复合模式及小麦单作模式为研究对象,设计了4种修枝处理,比较不同修枝处理内小气候因子、小麦产量及品质的差异,并分析影响小麦产量及品质的主要小气候因子。结果表明:杨—麦复合模式内小麦穗长、单穗重、麦粒长、千粒重及产量均显著低于对照模式,但小麦营养成分含量表现不一;对杨—麦复合模式内欧美杨107进行不同修枝处理后,处理Ⅰ内小麦产量及品质要好于其他3种修枝处理。可见,小麦产量及品质随杨—麦复合模式内小气候因子的改变而发生变化,而小气候因子的变化与杨树修枝强度与方法密切相关。因此,为实现杨树与农作物"双赢",应采用处理Ⅰ的修枝方法开展杨树修枝,即从造林第5年春季修除第1年生的轮生枝,第6年春季修除第2年生的轮生枝。In this paper the poplar-wheat agroforestry pattern and wheat monoculture pattern were the study objects and the differences of the microclimate, wheat yield and quality in the patterns with 4 kinds of pruning treatments designed were compared,and the main microclimatic factors affecting the wheat yield and quality were analyzed. The results showed that the ear length, one ear weight, kernel length, 1000-kernel weight and yield of wheat in the poplar-wheat agroforestry pattern were significantly lower than those in the control pattern while the nutrient contents of wheat were mixed;The wheat yield and quality with treatmentⅠwere higher than those with the other 3 treatments indicating that the wheat yield and quality varied with the change of the microclimate factors in the poplar-wheat agroforestry pattern,which was closely related to the pruning intensity and method. Therefore,to achieve the win-win result of poplar and crops,the pruning method of treatmentⅠshould be adopted pruning in the 5th spring after forestation the whorled branches grown in the first year and pruning in the 6th year the whorled branches grown in the second year.
