【摘要】 研究不同遮光度对栽培长白楤木生长发育的影响。结果表明,适度遮光可促进长白楤木的生长,提高植株高度,但对茎粗促进作用不明显。适度遮光更有利于植株干物质的积累,但是重度遮光不利于长白楤木种子的成熟。不同遮光处理延迟了长白楤木的开花期和结果期,尤其是80%遮光处理,到了秋季枯萎期种子不能成熟。田间观察30%、50%遮光处理并没有影响种子的成熟,因此,只有重度遮光不利于长白楤木种子成熟。更多还原

【Abstract】 Of different degrees of shading cultivation Aralia continentalis the impact of growth and development.The results show that moderate shading Aralia continentalis promote growth,enhance the plant height,but to promote the role of stem diameter was not obvious.Moderate shading is more conducive to the accumulation of dry matter,but the shading is not conducive to severe Aralia continentalis mature seeds.To deal with different shading Aralia continentalis delayed the flowering period and the results of a view,especially the 80% shading treatment,withered in the autumn period of not maturing seeds.Field observation of 30%,50% shading did not affect the processing of the mature seed,therefore,is not only conducive to severe shading Aralia seeds mature wood.更多还原
