4种落叶松的引种效果与光合日进程

Analyses on Introduction Results of 4 Tree Species in Genus Larix and Diurnal Photosynthetic Changes

    摘要
  • 摘要: 在黄土高原丘陵区,引种的4种落叶松生长正常,但受水分限制,生长缓慢,其生长量大小排序为:华北落叶松 > 日本落叶松 > 兴安落叶松 > 长白落叶松;日平均光合速率大小排序为:日本落叶松 > 华北落叶松 > 兴安落叶松 > 长白落叶松;水分利用效率排序为:华北落叶松 > 兴安落叶松 > 日本落叶松 > 长白落叶松.华北落叶松可作为今后主要发展的树种.

     

    Abstract: The 4 tree species in genus Larix introduced into the Loess Hilly Region in northwest China grew normally though the growth rate was small because of water deficiency.The growth rate of these 4 tree species was ordered as: Larix principis-rupprechtii > Larix kaempferi > Larix gmelini > Larix olgensis.The mean of the diurnal photosynthetic rate was in order: Larix kaempferi > Larix principis-rupprechtii > Larix gmelini > Larix olgensis, whereas the transpiration rate of the 4 was ordered as: Larix principis-rupprechtii > Larix gmelini > Larix kaempferi > Larix olgensis.It was demonstrated by the results that Larix principis-rupprechtii might be extensively planted in the Loess Hilly Region in the future.
