摘要

在陕北丘陵沟壑区

以油松纯林为对照

通过对油松与沙棘行状混交、带状混交和宽行混交沙棘平茬、宽行混交沙棘不平茬的油松树高、地径、树冠、顶梢生长、存活率等的监测研究

结果表明

不同方式混交的油松在栽后前3 a的生长状况与纯林无差异.当混交林的沙棘覆盖度达到70%以上后

行状混交和宽行混交沙棘不平茬的油松生长量开始下降

栽后6~7 a大量死亡

第8 a基本死完;宽行混交沙棘平茬的油松

随着平茬沙棘的萌生

油松的生长量大于纯林

在萌生沙棘生长的第3 a

沙棘覆盖度达40%~45%时

油松的生长量明显大于对照;带状混交的油松

当沙棘侵入油松林带后

油松的生长量大于对照

当沙棘的覆盖度达40%~45%时

油松生长速度与纯林的差异明显.不同年份的降水量对油松的生长影响显著

但滞后1 a.

Abstract

After observed Chinese pine's height

trunk diameter

top shoot growth

crown diameter

survival percent when mixed with seabuckthorn by row

by strip

by wide row and wide row cut seabuckthorn and compared them with Chinese pine of only Chinese pine woods in loess hilly and gully region of northern Shaanxi

the results show:Chinese pine's growth of mixed woods has no distinctly difference after planted three years later.When mixed sea buchthorn coverage density achieves at 70%

Chinese pine's growth of mixed woods by row and by wide row become slowly

after being planted six to seven years

a flock of Chinese pine begin to perish

eight years later

all of Chinese pine has deceased. As cut sea buckthorn germinate

Chinese pine of mixed woods by wide row cut sea buckthorn grow faster than that of only Chinese pine woods

after cutting sea buckthorn three years

when germinated seabuckthorn coverage density achieves at 40%~45%

Chinese pine's growth of mixed woods by wide row cut sea buckthorn become distinctly faster than that of only Chinese pine woods.When sea buchthorn intruded the strip of Chinese pine

Chinese pine of mixed woods by strip grow faster than that of only Chinese pine woods

eight years later

when seabuckthorn coverage density achieves at 40%~45%

Chinese pine's growth of mixed wood by strip become distinctly faster than that of only Chinese pine.Annualprecipitation has big influence on Chinese pine growth

but the influence lags one year.
