造林 栽植杨树要速生,优良品种须选准,I-69、 I-72、中林46都可行,新推2001杨引种应精心。适地适树是基础,砂质壤土最适应,岗地粘土生长慢,长期积水不适应。五大一深和一管,一条一条要记清:大穴深宽各1米,大肥施足穴底中,大水浇透压根水,大苗健壮要栽深,大株行距南北向,通风透光便间作;苗木标准高3米,随栽随运随时起,加强管护保成活,责权分明利自己。栽植季节很重要,春栽秋栽都适合,春栽二月中旬始,清明过后莫栽植,十月气爽栽树好,气温转冷己生根,严冬天寒莫栽树,顶凌造林难成活。若想栽树快点富,理想树种选杨树,熟记口诀灵活用,速生成材有保证。
Afforestation planted poplar fast-growing, fine varieties must be selected, I-69, I-72, Zhong Lin 46 are feasible, the new 2001 introduction of the introduction of Yang should be carefully. Appropriate tree is the foundation, the most suitable sandy loam, Kong clay slow growth, long-term stagnant water does not adapt. Big five and a deep and a tube, one by one to keep in mind: a large hole wide and deep 1 meter, large enough to apply foot acupuncture points, large water drench root water, seedlings robust to planted deep, large lines from north to south, ventilation and light Then intercropping; seedlings standard 3 meters high, with the plant from time to time with the transfer, and strengthen the management and protection Paul Survival, responsibility and authority to distinguish themselves. Planting season is very important, autumn planting are suitable for spring, spring planting mid-February, Mo-planting after Ching Ming, cool in October, planting trees, cold temperatures have rooted, winter and winter planting trees, top Ling Ling Afforestation difficult survival . If you want to plant faster hurry, the ideal tree species of poplar, mature memorize formulas flexible use of fast-growing timber is guaranteed.
