摘    要:试验研究了松嫩草地不同生境和密度下五脉山黧豆地上部生育规律和生物量。结果表明:人工栽培五脉山黧豆植株比野生植株具有较大的株高、分枝长度、分枝数和生物量。其中,人工一年生种群株高和单株生物量比野生植株平均增加了19.1 cm和11.66 g。野生种群植株不同密度间个体生长的差异不显著(P>0.05);人工种群植株不同密度间个体生长差异显著(P<0.05),体现了密度制约的效应。人工二年生种群植株比一年生植株有较大的密度竞争压力,在生物量等方面比一年生种群植株小。

关 键 词:五脉山黧豆  野生  栽培  密度  生长发育  生物量

Abstract:The comparative study on aboveground growth rule and biomass of Lathyrus quinquenervius between different habits and densities in Songnen grassland was conducted.The results show that: plants in field are greater in height,ramification length and number,and biomass than those of wild.There is no significant difference in density of wild plants but the difference of plant density in field is significant.Plants,especially those in two-year populations, are bigger in low density than those in high density in field,resulting from the effect of density dependence.The plants in two-year populations have more pressure of density competition,and show much smaller shape in biomass.
Keywords:Lathyrus quinquenervius  wild  planting  density  growth evelopment  biomass
