摘要

通过刺槐、沙棘、二色胡枝子、柠条和毛条等灌木树种造林密度的试验

在干旱和半干早地区

刺槐林(1×1)米的密度

5年内可丰产并提早发挥水土保持效益;雨水正常

此密度的丰产期更长。沙棘林以(1×1)和(1×1.5) 米的密度较适宜。二色胡枝子林以(0.3×1)米的密度

4年生以前可以

第5年要视降水情况;(1×1)米的密度可以继续发展。柠条分枝多

造林以(0.5×1.5)米的密度较适宜。毛条分枝少

(条播×1.5)米的密度比(0.5×1.5)米的密度产量高

生长也好。

Abstract

The experiment on forest culture density of Robinia pseudoacacia

Hippophae Rhamnoides

Lespedeza bicolor

Caragana microphylla and Caragana korshinskii in the semiarid area showed that the high yield may beobtained for R. pseudoacacia with density 1×1m

if the rainfall is normal

the period of high yield with such density will last. The suitable donsityof crop for H.rhamnoides is 1×1m and 1×1.5m .The density 0.3×1m is rightfor L. bicolor before 4 years

after 5 years it depends on rainfall.C. microphylla branches out more

so the density 0.5×1.5m is suitable

while C. korshinskii ramifies less

the yield with density (seeding in lines×1.5m) ishigher than 0.5×1.5m

and its plants grow better.
