we carried out experiment of selecting grasses with strong regeneration
high production and high WUE(water using efficiency).We studied the production
the rate of growth and the efficiency of water usage of regenerating grasses of 4 types in 2005.It shows that the second generation grasses of introduced types have higher production than the local grass
hooked Bristlegrass.Three types of introduced grasses
Macroptilium atropurpureum Siratro
Setaria sphacelata Narok
Brachiaria decumbens Basilisk are high throughput
more WUE
and stronger ability of regenerating
they thus are the grasses suitably planted in the hot-dry area of Jinsha River watershed.
