中文拼音 [yìngyángmáo]
硬羊茅
英文
hard fescue-
The bud bank is composed of 3 age classes bud on leymus chinensis, arundinella hirta and hordeum brevisubulatum populations, 2 age classes bud on hemarthria japonica, calamagrostis epigeios and c. rigidula populations. the age structure of bud is obviously an increasing model in all of 6 grass species
羊草、野古草和野大麥種群芽庫由3個齡級組成，牛鞭草、拂子茅和硬拂子茅種群由2個齡級組成， 6種禾草芽庫的年齡結構均為明顯的增長型。The tiller - nodes of 6 species of rhizome grass, including leymus chinensis, hemarthriajaponica, arundinella hirta, calamagrostis epigeios, c. rigidula, hordeum brevisubulatum in songnen plain, can live at best for 2 to 5 years, and do 2 to 4 propagating generations which is the same as the age class of tiller in number. the age structure of population is an increasing model which the young tiller is more than the old at quantity and biomass. during the whole growing season, the age spectrum varies for each species
松嫩平原，羊草、牛鞭草、野古草、拂子茅、硬拂子茅和野大麥等6種根莖型禾草種群的分蘗節最多可以存活2 5個年度，可以進行營養繁殖2 4個世代，分蘗株的齡級數與分蘗節營養繁殖的世代數相同，在種群分蘗株的數量和生物量上，生長季的各個時期均以幼齡分蘗株占較大比例，呈現為明顯的增長型年齡結構，各種類的年齡譜組成各異。The negative correlation of the dry matter production to the age class of rhizome indicates level of significance ( p < 0. 05, po. ol ) in leymus chinensis, calamagrostis epigeios and c. rigidula populations
羊草、牛鞭草和硬拂子茅種群根莖的干物質積累量與齡級間的負相關關系達到顯著和極顯著水平。The rhizome of grass, including leymus chinensis, hemarthria japonica, arundinella hirta, calamagrostis epigeios and c. ? rigidula populations, can normally live for 3 to 4 years which is the same as the age class
羊草、牛鞭草、野古草、拂子茅和硬拂子茅種群根莖的存活年度一般為3 4年，根莖的齡級數與存活年度相同。The winter tiller is more than the spring tiller at quantity hi leymus chinensis, calamagrostis epigeios and c. rigidula population at the beginning growing season. it is an efficient strategy to increasing survival fitness and propagating potential for rhizome grass to grow many active and strong winter tillers
生長季初期，羊草、拂子茅和硬拂子茅種群返青的分蘗株以冬性植株多於春性植株，冬性植株生活力旺盛、抗性強，形成冬性植株是根莖型禾草種群提高生存適合度，增強營養繁殖力的有效策略。分享友人
