light graze meaning in English
轻刮痕
Examples
- Influence of fencing and light grazing on enclosed alpine steppes in the qinghai lake area
围栏内禁牧与轻牧对高寒草原群落的影响 - As a case study , the responses of leymus chinensis steppe of songnen plain in northeast of china to human being activity ( light grazing , middle grazing , heavy grazing and overgrazing ) were discussed based on the field observed data
结果表明，随著放牧强度的增加，羊草草原的植被盖度和生物量随之降低，优势羊草群落将逐渐被盐生植物所替代，群落结构趋于简化，物种向旱生化和盐生化演替。 - The paper summarized the research for the effects of different grazing intensity on grazing behaviour , grazing grass species and productivity of sheep in recent years , the result showed that : there was a negative correlation between the live weight gain per sheep and the grazing intensity , but there was positive correlation between the live weight gain per hectare and the grazing intensity ; feeding intake of sheep decreased when the grazing intensity become heavier ; there was not significant effect of different grazing intensity on sheep breeding indexes ; as long with the grazing intensity become heavier , the feeding time of sheep increased while resting and idling time decreased , but feeding intake per hundred mouths and daily intake reduced while intake velocity increased ; sheep feeding adaptability is relative ; the light grazing was beneficial to promote mutton quality , but mutton quantity and gross economy benefit was low
摘要根据近几十年来放牧强度对绵羊放牧行为、采食植物组成和生产性能的影响进行了综述，得出以下结论：绵羊的个体增重与放牧率之间呈线性负相关，而公顷增重与放牧率之间呈正相关；绵羊的采食量随著放牧强度的加重而降低；放牧强度对母羊繁殖性能各指标影响差异不显著；随著放牧强度的加重，绵羊的采食时间增加，游走、反刍卧息时间减少；每百口采食量和日采食量减少，而采食速度增加；放牧绵羊的嗜食性是相对的；轻牧有利于提高肉的品质，但是产肉量低，总的经济效益不高。
