| 摘 要： | 根据近年国内外发表的有关草地刈割对豆科牧草影响方面的论述及研究结果,分析了刈割对豆科牧草生长发育及形态结构、生产力、品质及贮藏物质的含量和分配、光合生理生态、根系形态和土壤微环境以及植物种群和植物体内酶含量等的影响, 得出适宜的刈割能促进豆科牧草的再生和分蘖(枝),提高产量和改善营养价值,有利于草地植被结构改善,提高优良牧草的比例.为确定合理的刈割制度,保证尽可能减少或消除刈割的不利影响,对草地合理利用、草地刈割机制认识和人工草地建植等提供理论和技术依据.

| Abstract: | The responses of Legumes to defoliation in terms of growth,morphological structure,biomass,quality and distribution of stored nutrients,photo-physiological characteristics,root system,soil micro-environment,community and enzyme content were reviewed and analyzed.It could be concluded that an appropriate defoliation was propitious to the vegetative propagation of grassland plants and the improvement of grassland community structure.It was important to provide theoretic and technical guidance for defoliation system and reduce or eliminate its negative effect and understand the physiological mechanism. |
