摘要
探索天然牧草最合理的调制方式,提高天然牧草干草的品质,是当前我国草原牧区畜牧业发展的关键所在。本实验以天然牧草为实验材料,通过控制天然牧草刈割时间以及集拢时间,研究不同调制方式下天然牧草营养物质和水分含量的变化。结果表明:同一天内刈割时间越晚,天然牧草的营养物质含量越少,牧草返潮作用越严重;当天然牧草刈割后,晾晒72h均可达到安全含水量;天然牧草达到安全含水量时要立即进行打捆贮藏,反之,牧草的营养物质含量会随晾晒时间的增加而降低。
The key to the development of animal husbandry in grassland pastoral areas is exploring the most reasonable modulation of natural pasture and improve the quality of natural pasture hay.In this experiment,natural pastures were used as experimental materials to study the changes in the nutrient content and moisture content of natural pastures under different modulation methods by controlling the cutting time and gathering time of natural pastures.The results showed that the later the cutting time in the same day,the lower the nutrient content of natural forage,the more severe the moisture effect of pasture;when the natural pasture is cut off,the safe moisture content can be achieved after drying for 72 hours;when the natural pasture reaches a safe moisture content,Bundling and storage are carried out immediately.On the contrary,the nutrient content of grasses will decrease as the drying time increases.
