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.

Key words: plant surface, lactic acid bacteria, adhering to, silage
