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, cm以上; cm以上; 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 cm or more; Acacia diameter cm or more; Walnuts ground diameter cm or more.
2 造林密度及配置、混交方式
2 afforestation density and configuration, mixed mode
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。
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.
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。
