THE PRELIMINARY STUDIES ON BIOLOGICECOLOGICAL CHAKACTERS AND UTILIZATION OF PENNISETUM LONGISSIMUM IN GUIZHOU

Pennisetum longissimum is a grass recorded by S. L.Chen and Y.X. Jin in 1984. The growth charcters, five nutritive components by the dry weight and the distribution of the plant in the different regions in Guizhou were Studied. The results showed that Pennisetum longissimum was a grass of both much biomass and high nutritive value. There was the value of further exploitation and utilization for the plant. And five natural concentrated areas of Pennisetum longissimum had been determined in Guizhou.
