本研究在露天盆栽条件下进行，在冬季小麦苗期采用不同程度的刈割处理模拟植食动物啃食，试验刈割程度设轻度、中度、重度（在小麦苗期分别刈割整个植物地上部分高度的33％、50％、100％）3个处理，以不刈割处理为对照（ CK），待小麦返青后测量各项形态和生理指标，收获后比较不同处理的生物产量和经济产量，以研究被植食动物啃食后冬小麦的生长和生理变化，以及冬小麦的补偿生长类型与补偿机制。结果表明：只有重度刈割在试验处理后短时间内对少量植株的存活有影响，在小麦发育早期推迟冬小麦叶、茎和穗的发育；刈割作用对冬小麦成熟时的叶片数影响不大；中度刈割可以刺激冬小麦植株增高，在一定时间后产生超补偿现象，而重度和轻度刈割对株高产生欠补偿效应；轻度刈割可促进穗增长以及冬小麦各部分生物量的增加而产生超补偿效应，中度和重度刈割则产生欠补偿效应，且刈割程度越重，欠补偿效应越明显；刈割对冬小麦地下部分的影响较地上部分大。

Research the growth and physiology changes of winter wheat to simulate herbivores grazing by pot experiment.Different clipping intensities at seedling stage were conducted in winter , each morphologic and physiological indicator was measured after the stage when winter wheat turned green, and the effects of different levels of clipping on biomass and economic yield were compared on harvest.The compensatory growth style and mechanism of winter wheat was the primary study.Cut up 0% ( CK) , 33%, 50% and 100% of the whole plant in height at seeding stage to meat with the four levels of treatments the check, light-clipping, moderate-clipping and heavy-clipping.Set one check and 3 replicate pots were prepared for each left treatment.Culture winter wheat in the open air from seeding to harvest.The results showed that only the heavy-clipping had a little effect on the survival rate within a short time just after experimental treatments.Heavy-clipping delayed the development of leaves, stems and ears in the earlier stage of their own development. Grazing had little impact on the leaves number in mature period. Compared with the check, moderate-clipping increased the height of plants, then produced over compensation phenomenon after a certain period of time, light-clipping increased the length of spikes and the weight of all parts of winter wheat, in contrast with the moderate-clipping and heavy-clipping.Moreover, the intensity of under-compensation increased with the clipping levels raising.The effects of clipping on underground parts were larger than that of above-ground parts.
