植树注意事项植树节英语手抄报内容

　　春天是植树最适合的时候，因为在这期间树木正处于萌动前的休眠期，尚未生根发芽，对于温度、湿度等环境条件，反应迟钝，生理活性较低，可耐初春冷热 无常的剧变气候。待栽植后，逐渐回暖，气温渐趋稳定，土壤解冻，雨水渐多，正好赶上树木苏醒，进入树木生长的大好季节，所以树木春栽是符合生长发育规律， 一般来讲，春栽宜早不宜迟。

　　Spring is the most appropriate time to plant trees, because trees before is in the stirring during this period, has yet to take root, for temperature, humidity and other environmental conditions, unresponsive, physiological activity is low, resistant to cold and hot spring impermanent changing climate. After being planted, gradually warming, the temperature is stable, soil thawing, more rain, awaken coincided with trees, into the trees grow a good season, so the plant trees in spring is in line with the growth and development regularity, generally speaking, the spring planting sooner rather than later.

　　植树除应注重季节外，在栽植中有几个问题也是应该注意的：

　　, besides should pay attention to season to plant trees there are a few problems in planting and it should be noted:

　　一、粗耕细作

　　One, to have a very crude plow

　　树木的生态习性虽与农作物有异，但对土壤要求仍然是精耕细作，尤其划拨给植树造林用的土地，往往都不是熟地良田，更需要进行较彻底的深翻，深度 在40至50厘米，以便疏松土壤，增加蓄水保墒的能力。整地也要细致，否则树木无法扎根，影响成活。采用沟植的要求整成水平沟，以利灌溉，同时也比较美 观。

　　Although ecological habit of the trees and the crops are different, but the soil requirements is still intensive cultivation, especially for afforestation land transfer, often are not cultivated land fertile land, more needs to be more thoroughly the commune, 40 to 50 cm in depth, so that the loose soil, increase the ability of filling soil conservaton. Site preparation is meticulous, trees won't be able to take root, affect survival. Using whole become level trench trench planting demands, and to facilitate irrigation, was also more beautiful.

　　二、树种的选择

　　Second, the choice of tree species

　　要考虑到树木植株枝叶的色彩、形态、风韵，使与周围环境相协调，起到美化的作用。既要考虑到树木的抗污、防毒、净化空气的特殊功能，又要考虑到 树种是否适应土壤性质，如土壤瘠薄的可种白榆、松、柏等，土层较肥厚的可种杨树、泡桐等，盐碱地可种沙枣、榆树等。起树时，应注意勿伤及根系，苗木必须健 壮，无病虫害。

　　Take into account the trees plant foliage color, shape, charm, make in harmony with the surrounding environment, have the effect of beautification. Should not only consider the trees of the fouling resistance, gas, air purification, the special features, also want to consider whether tree species to adapt to the soil properties, such as soil barren can kind of white elm, pine, cypress, etc., the soil hypertrophy can be kind of poplar, paulownia, saline-alkali land can be kind of elaeagnus angustifolia, elm, etc. Don't hurt the root tree up, we should pay attention to, must be the healthy strong seedlings, no plant diseases and insect pests.

　　三、树木的栽植

　　Third, the planting of trees

　　树坑要挖大，直径应比树苗的根幅大三分之一，挖深要超过长度的三分之一，并应清除掉坑内的煤渣、石灰等杂物，以利树木扎根生长。株行距应以林木 用度而定，如防护林用2米×2米，生产小径材可用1米×1米或2米×2米，大径材用4米×4米或6米×6米，甚至8米×8米。株行距必须笔直对称，植株不 能歪斜。栽植时要细心，应边填土边提苗，使根系舒展不扭曲，填土后必须用脚分层踩实。

　　Buffalos making big diameter should be one of three points than root of seedlings, digging deep to more than a third of the length, and shall remove the pit coal cinder, lime and other sundry, roots growth. Plant spacing should be in forest tree measurements, such as protection forest in 2 m x 2 m, trail production material available 1 m * 1 m or 2 m * 2 m, big diameter wood use 4 m * 4 m or 6 m * 6 m, 8 m even x 8 m. The plant row spacing must be straight and symmetric, plants can not skewed. Should careful when planting, should fill and seedlings, root stretch not distort, after filling must be layered with the feet trample.

　　四、养护管理

　　Fourth, maintenance and management

　　树木的养护管理很重要，栽植后要立即浇水三次，并要浇透，不足的要补水。要注意浇水后的根部培土工作，要经常锄草松土，如有间作不能喧宾夺主， 要保证树木的成活。施肥上，应在挖坑时，在树坑底部先施基肥，栽植后可用厩肥或化肥(每株250克左右)，用沟施或窝施肥料，促其生长。在养护管理上，应 该分片承包，固定专人管理，以保证成活率提高，树木旺盛成长。

　　Maintenance management of the trees are very important, planting water immediately after three times, and be drenched, insufficient filling water. Pay attention to the watering roots ridging after work, want to often weeding scarification, intercropping cannot a presumptuous guest usurps the host's role, if any, to ensure the survival of the trees. Fertilization, when should dig a hole, the bottom of the buffalos basal dressing first, after planting can use manure or fertilizer (per 250 grams), with a groove or nest fertilizer, promote its growth. On the maintenance management, contract, should be divided fixed personnel management, to ensure that improve the survival rate of trees grow well.
