摘要
大量试验证明,苇状羊茅在当地土壤及气候条件不栽培,分蘖能力强,生长迅速,地上生物量及株高的增长动态均符合logistic曲线,而生物量的衰减动态符合y=a+blnx曲线,峰值在7月,绿期长达250d左右,鲜草产量为37500kg/hm^2.
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.
