| Abstract: | In this papar, many results show that its tillering capability is very strong. Its growth is very fast, and fresh grass yield is near 37500kg/hm2 under the conditions of local soil and climate. The dynamics model of accumulation of fresh grass and height are in conformity with the logistic equations, attenuation dynamics model of fresh grass fits in with y=a b lnx. Peak value is in July. Green last 250 days or so. |
