, 2015 测定3种土壤条件下不同品系羊草(Leymus chinensis)稳定同位素(δ13C)值、叶绿素(SPAD)值及主要营养成分,并探讨了其相关性与回归关系。结果表明,土壤因素对羊草BG-2、B品系的δ13C值和SPAD值有较大影响,对羊草Y1品系SPAD值影响不大;羊草δ13C值与土壤有机质、碱解氮、全盐及土壤水分含量相关系数在0.737~0.800,除与土壤全盐含量之间显著相关外 ...

, 2007 针对白三叶Trifolium repens与黑麦草Lotium perenne、弯叶画眉草Eragrostis curvula混播时导致后2种植物数量减少甚至消失的现象,通过白三叶的根部、地上部和植株水提液对黑麦草和弯叶画眉草种子进行发芽实验,以及白三叶与黑麦草、白三叶与弯叶画眉草种子混播进行实验,研究表明:白三叶(幼苗、2年生植株根及茎叶)的水提取液在原液以及稀释20倍时对受体植物的胚根和胚芽的生长均产生明显的抑制作用,而在100倍稀释液时表现出一定的促进作用 ...
