一、关于栽种宽度和密度栽植宽度依各地条件而定,人地矛盾突出的地方窄些,反之则宽些,但一般不低于15米,有条件的可达50米(结合经济林)。 15米模式:①均栽乔林,株行距3×2,2米行距,3米株距,套种农作物。②5行乔木,3×2米,2行经济作物,经济作物为果树或有经济价值的灌木、花草均可。 50米模式:①10行乔木,3×2米。10行经济林,2×3米。②均栽乔木,考虑栽种部分速生丰产林,解决效益问题。 10—50米之间宽度可参照以上两标准。关于栽植密度,从形象建设角度来看应加密栽植,不能按常规情况而论,增加密度一次成林,可增加绿化效果和环境形象,到一定年龄(5年)再间伐,还有经济收入。
I. Planting width and density planting width Depending on local conditions, the contradiction between human and land areas are more narrow, and vice versa are wider, but generally not less than 15 meters, conditional up to 50 meters (with economic forest). 15m mode: ① planted Qiao Lin, spacing of 3 × 2, 2 m row spacing, spacing of 3 meters, interplanting crops. ② 5 rows of trees, 3 × 2 meters, 2 rows of cash crops, cash crops, fruit trees or economic value of shrubs, flowers can be. 50 meters mode: ① 10 rows of trees, 3 × 2 meters. 10 lines of economic forest, 2 × 3 meters. ② are planted trees, consider planting some quick-growing high yield forest, to solve the problem of efficiency. 10-50 meters width can refer to the above two standards. On the planting density, from the perspective of the image construction should be encrypted planting, can not be the case in general, increasing the density of a forest, can increase the greening effect and the image of the environment, to a certain age (5 years) and then thinning, as well as economic income.
