Abstract
The present paper was intended to use the fresh forage yield,regeneration rate and number of tillers as the major observation indexes for studying the effect of different cutting stubble handlings and mowing times on growth and production performance of Sorghum sudanense(hay king) stapf.in dry-hot valley of Yuanmou County.The results showed that the grass has a good adaptability in the dry valley area and can be gotten 5 times in its growing season;different cutting stubble handlings and mowing times are significant affect the ability of regeneration and tiller and the second one is the greatest impact.The increasing number of mowing stubble times significantly slow down the regeneration rate and significantly enhance the number of tillers by contraries;the grass has a difference significantly in up-ground biomass between any two groups from different stubble heights and mowing stubble times;for the measurements of total yield and regeneration rate,the mowing handling treatment of 10cm stubble height is the best choice, which can make the average recycling rate up to 2.50cm/d and fresh yield 125 760.6 kg/hm2,also this stubble height showed a more stable biomass in different mowed periods and remain a more sustainable growth ability in its reason.
