多年生草地的刈割时间和次数必须根据草种的生物学特性、生理生态变化、立地环境条件和利用方法来确定。现在有些地方不按科学规律办事,随意刈割,使多年生草地寿命缩短,产草量下降,草的饲用品质变劣,甚至使草霉烂变质,根茬窒息死亡,造成很大的经济损失。因此,要十分重视草地的刈割适期和方法。
Mowing time and number of perennial grassland must be determined according to the biological characteristics of grass species, physiological and ecological changes, site environmental conditions and utilization methods. Nowadays, some places do not work according to scientific laws and are free to cut. As a result, the life span of perennial grasslands is shortened, the yield of grass is reduced, the quality of feed of grass is deteriorated, and even the grass rot is deteriorated and the stubble is killed by root stubble, resulting in great economic losses. Therefore, we must pay great attention to the lawn mowing period and method.
