摘要:

植物表面附着乳酸菌(LAB)的种类与数量是决定其青贮发酵品质的关键因素,也可能影响植物的健康生长。研究发现植物表面LAB受到诸多因素的影响。本文对植物特性(叶表面结构、叶表面营养成分、化学组成等)、外界环境(温湿度、降雨、氧气、光照等)、田间管理(施肥、刈割)等因素对LAB种类与数量分布的影响及机理进行了详细的论述,以便更好地把握植物表面LAB的分布情况,从种植管理、收获技术等入手提高植物表面优良LAB的种类与数量,为调制优质青贮饲料和植物健康生长提供科学依据。

Abstract:

The species and number of lactic acid bacteria(LAB)adhering to the surface of forage crops are the key factors that determine the fermentation quality of silage,and might also affect the growth of forage crops. Studies have found that LAB on the surface of forage crops are affected by many factors. This paper discussed the effects and mechanism of plant characteristics(leaf surface structure,nutrients,chemical composition,etc.),environments(temperature,humidity,rainfall,oxygen,photoperiod,etc.)and field managements(fertilization and mowing)on the distribution of epiphytic LAB,in order to well understand the situation of LAB on the surface of plants. Thus,we may increase the types and quantities of excellent LAB on the surface of plants through planting management and harvesting techniques,which will provide scientific bases for the production of high-quality silage and the healthy growth of plants.
