通过研究干热河谷坚尼草不同刈割周期及留茬高度对其生产性能的影响,结果表明：随着刈割周期延长,坚尼草产草量、株高和分蘖数逐渐增加,以20～30d刈割产草量相对较高,分蘖强,差异不显著,但生长高度与10～15d刈割差异显著;不同刈割高度对坚尼草产草量没有显著影响,随着刈割高度增加,产草量和分蘖数逐渐降低,而生长量增加,刈割高度为10～20cm时,其产草量、分蘖数和生长性较好。为促进其分蘖、生长和提高产草量,其刈割周期与刈割高度分别25～30d和10～20cm为宜。

The paper studied the effect of mowing interval on the growth and yield of Panicum maximum in dry-hot Valley. The results showed the forage yield, height and tiller number were gradually increased as the mowing interval extension. The forage yield was high and the tillering was strong when mowing interval was 20-30 days,but,the difference was not significant. The plant height was significant difference in 10-15 days of mowing interval. There were no significant difference of forage yield in different mowing interval. The forage yield and tillering reduced as the cutting height increased,however,the growth was increase. The forage yield, tilling and growth were better when the mowing height was from 10 cm to 20 cm. The best mowing interval was 25-30 days and the best mowing height was 10-20 cm in production management of Panicum maximum.
