荒山荒地造林技术措施
1 造林树种的选择
The selection of afforestation tree species
根据襄汾县东西两山不同的立地条件、 各树种的生物学特性及在不同立地类型的生长表现,考虑树种来源、 劳力、 资金条件等因素,本着适地适树和优先选用优良乡土树种的原则进行荒山绿化树种的选择。苗木一般选择1~2 a生,侧柏最好使用容器苗,高度25.0 cm以上;刺槐地径1.0 cm以上;核桃地径1.5 cm以上。
According to the different site conditions of xiangfen things two
mountains, the biological characteristics of various tree species and
growth performance in different site type, consider species origin,
condition factors such as labor, capital, in line with to the principle
of optimal tree and select excellent native tree species for greening tree
species selection of barren hills. Nursery stock generally choose 1 ~ 2
a, biota orientalis had better use container seedlings, height 25.0 cm
or more; Acacia diameter 1.0 cm or more; Walnuts ground diameter 1.5 cm
or more.
2 造林密度及配置、 混交方式
2 afforestation density and configuration, mixed mode

2.1 造林密度 侧柏一般栽植在山坡的中上部或条件差的山脊,穴状或鱼鳞坑整地,密度可掌握在220~330株/667 m2;刺槐、 核桃适宜在土壤条件较好的水平阶及梯田成片栽植,密度一般为110~150株/667 m2。
2.1 afforestation density using general plant in the slope of the upper
or poor ridges, cavernous or scale-hole ploughing and density can be
master in 220 ~ 220 plants / 330 m2; Acacia, walnut in soil conditions
good level of order and planting of terraces and density is generally 110
~ 110 plants / 150 m2.
2.2 种植点配置 为充分发挥水土保持林的水土保持作用,侧柏、 刺槐在种植点配置上选用”品”字形,核桃采用正方形的配置方式。
2.2 growing point is configured to give full play to the water and soil
conservation of soil and water conservation forest, arborvitae, acacia,
choose "goods" glyph on planting some configuration, walnut square
configuration method.
2.3 混交方式 根据山区地形地块的自然分布情况,树种混交方式一般选用不规则的块状混交。
2.3 mixed way according to the nature of mountainous terrain block
distribution of tree species chosen commonly irregular block mixed mixed
mode.

3 整地方式
Three site preparation modes
整地是造林前的一项重要环节,按照水土保持的要求,针对坡的上下位置及坡度的大小,并根据实际情况采取不同的整地方式,尽量减少破土面,因地制宜。
Site preparation is an important link for afforestation in front of,
in accordance with the requirements of the soil and water conservation,
in view of the location and size of the slope up and down slope, and adopt
different ways of soil preparation according to actual condition, to
minimize the ground surface, adjust measures to local conditions.
3.1 山坡上一般对山坡上部及25°坡以上的地段,采用穴状、 鱼鳞坑整地,规格穴状坑穴径30.0~40.0 cm,深20.0~40.0 cm,穴面要稍向内倾斜;鱼鳞坑长径30.0~50.0 cm,短径30.0~40.0 cm,深20.0~40.0 cm,外侧有土埂,半环状,高10.0~20.0 cm,坑面外高里低,坑上方左右两角斜开引水沟,以积蓄坡面径流。
3.1 general on the upper slopes and slopes more than 25 ° slope area,
USES the cavernous, and scale-hole, site preparation, specifications
cavernous holes diameter 30.0 40.0 cm, 20.0 40.0 cm deep, the hole surface
slightly inward tilt; Scale-hole diameter 30.0 50.0 cm long, the short
diameter 30.0 40.0 cm, 20.0 40.0 cm deep, outside have TuGeng, half ring,
10.0 ~ 20.0 cm, outside the pit surface observed is low, so that both Angle
of oblique hole above open flume, slope surface runoff to savings. 资料内容仅供您学习参考，如有不当或者侵权，请联系改正或者删除。
3.2 对山坡中部及15°-25°坡的地方,采用鱼鳞坑、 水平阶整地,规格 鱼鳞坑同上,水平阶宽0.8~1.5 m,长以便于整平田面为宜,深30.0~50.0 cm。
3.2 to 15 °, 25 ° slope and slope, using scale-hole, horizontal soil
preparation, the above specifications and scale-hole, level of order 0.8
~ 1.5 m wide, long is advisable in order to leveling, a depth of 30.0 ~
50.0 cm.
3.3 对山坡下部及15°坡以下的地段,采用窄幅梯田整地,规格 宽2.0~5.0 m,长度随山坡情况而定,深30.0~50.0 cm,阶外缘培修土埂。
Under 3.3 to 15 ° slope and lower slope location, using a narrow
terraced land preparation, specification is 2.0 ~ 5.0 m wide, length over
hillsides, 30.0 50.0 cm deep, order the outer TuGeng culture.
4 造林时间
Afforestation of four time
根据山区土层浅薄,含水量低的特点,造林季节选择以春季、 冬季、 雨季造林为主。
According to the shallow mountain, the characteristics of low water
content, choosing afforestation season planting is given priority to with 资料内容仅供您学习参考，如有不当或者侵权，请联系改正或者删除。
spring, winter, rainy season.
4.1 侧柏以雨季造林为主,最适宜的造林时机是 进入雨季后下过一二场透地雨,然后天气连阴,此时造林成活率最高。切忌在无雨和降雨不多的时期强栽等雨,要严格遵循”三不栽”的原则,即”雨不透不栽,天不连阴不栽,雨过天晴不栽”。
4.1 biota orientalis is given priority to with afforestation of the
rainy season, the most suitable planting time is after entering the rainy
season or two field through the rain, and even the weather cloudy,
afforestation survival rate highest at this time. Period when there were
no rain and the rain is strong of avoid by all means, such as rain, we
will strictly follow the principle of "three-no", namely "the rain proof
not planted, it doesn't even Yin not planted, after a storm comes a calm
don't planted".
4.2 刺槐、 核桃一般以春季、 冬季造林为主 栽植时,一定要在根部蘸上泥浆。
4.2 acacia, walnut generally in spring and winter planting is given
priority to planting, must be dipped in the mud in the root.

5.1 容器苗造林 容器育苗造林要注意一下4个方面的问题:1)起苗时,应先挖
