摘要

本项研究采用正交试验

选用L

（3

）正交表拟定试验方案

对半干旱黄土丘陵沟壑区集流抗旱造林技术优化模式进行了研究

结果表明:影响造林质量的四个因素顺序是:造林树种（A）>栽植穴覆盖材料(D)>单株集流面积（B）>造林整地工程（C）。各因素中水平顺序如下:A因素中:刺槐>白榆>侧柏;D因素中:农膜>泡沫>作物秸秆;B因素中:2.5m

>2.0m

>1.5m

;C因素中:反坡梯田>水平沟>鱼鳞坑。半干旱黄土丘陵沟壑区集流抗旱造林技术优化模式是:A

即造林树种为刺槐

栽植穴覆盖材料为农膜

单株集流面积为2.5m

造林整地工程为反坡梯田。

Abstract

The optimization pattern of afforesative techniques with collecting runoff with collecting runoff to drough-resistance was presented by using L9（34）plan in the orthogonal experiments.It has shown that the order of four factors contributed to afforestative species(A)>cover material in the planted pits (D)>collection area of runoff for each tree(B)land preparation for afforestation(C).Of all factor

the order of the same kind is as follow;for A

Robinia pseudoacaia L.>Ulmus Pumila>Plalycladus arientalis Franco;For D

film>foam matcial>straw;for B

2.5m2>2.0m2>1.5m2;and for C

reverse slope terrace>level furrom>fish-scale pits.In semiarid loess hilly areas

the optimization pattern of afforestative techniques with collecting runoff to drough-resistance is A

Namely

afforeatative species is Rohinia Pseudoacacia L;the cover material of planted pits is film

the collectiom area of runoff for each tree is 2.5m2

and the land preparation pattern for afforestation is reverse slope terrace.
