| 摘 要： | 研究了东北羊草草原金狗尾草种群的生长，并利用灰色系统理论考察了环境因子对金狗尾草生长的作用规律．结果表明：金狗尾草的生长具有明显的季节进程，八月份生长最快，其生物量为963g／m2．温度、活性有机质、水解氮、含水量、速效钾具有较大的灰色关联度，其中温度、活性有机质、水解氮是金狗尾草生长的优势因子．PH、有效磷、电导率关联度相对较小，是限制因子．金狗尾草生长的最优模型为y=2．9592x1＋47．815212x2＋3．6702x3-91．4113

| Abstract: | This paper studied the growth law of Setaria glauca L. Beauv and effect of en-virorunnt factors on the Leymus chinensis grassland in the northeast China with the greytheory. The results indicated: the growth of Setaria glauca L. Beauv population has a dis-tinct seasonal variation. it grows best on August. driong eight environment factors, temper-ature. active organic rnater. hydrolyted nitrogen, water content, quick acting postassium toSetaria glauca L. Beauv growth have the best connected coefficients, those of temperature,active orgathe matter, hydrolyted nitrogen are promoted factors, pH, effective phosphorus.conductrate are restrictive factors.The best medel of Setaria gtauca L. Beauv growth is Y=2. 9592x1+47. 8152x2+3. 6702x3- 91. 4113 |
