生態護(hu)坡毯的施工

生態護坡(po)毯是(shi)(shi)一種常(chang)用(yong)的護坡綠化產品，產品主要(yao)(yao)是(shi)(shi)以(yi)(yi)植(zhi)(zhi)物纖(xian)維為基質(zhi)，所以(yi)(yi)生態護坡毯屬于環保型(xing)產品，在施(shi)工和護坡過程中不(bu)會對環境造(zao)成任(ren)何的污染，植(zhi)(zhi)物纖(xian)維可降解，涵(han)養土壤，為植(zhi)(zhi)物生長提供所需要(yao)(yao)的營養物質(zhi)，早日產生綠化效果(guo)。

生(sheng)態(tai)護(hu)坡毯的(de)(de)(de)施工(gong)方法：1、準(zhun)備工(gong)程(cheng)：挖(wa)除廢土、加種(zhong)(zhong)(zhong)(zhong)植(zhi)土（5-10公分(fen)(fen)厚）（根據需要(yao)）、夯實、整平、修坡時(shi)將(jiang)碎 石塊檢出，使坡面(mian)(mian)達到(dao)施工(gong)要(yao)求。2、綠化(hua)種(zhong)(zhong)(zhong)(zhong)植(zhi)：劃分(fen)(fen)為基(ji)質處理，綠化(hua)放樣(yang)(yang)，種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)撒播(bo)(bo)，鋪設(she)(she)草(cao)毯(tan)、養護(hu)(hu)五個。（1）、基(ji)質處理：先進行(xing)垃圾(ji)、雜草(cao)的(de)(de)(de)清理，種(zhong)(zhong)(zhong)(zhong)植(zhi)土應耙細整平，排水良(liang)好；并應進行(xing)土壤(rang)消毒，七天(tian)后(hou)，可(ke)(ke)(ke)依土壤(rang)肥力，施適量(liang)的(de)(de)(de)基(ji)肥。（2）綠化(hua)放樣(yang)(yang)：以(yi)(yi)設(she)(she)計(ji)為依據，先放毛(mao)樣(yang)(yang)，如平面(mian)(mian)布置與現場不(bu)利，應及時(shi)告(gao)訴工(gong)程(cheng)監理，以(yi)(yi)便設(she)(she)計(ji)單位(wei)作(zuo)變更設(she)(she)計(ji)。試放樣(yang)(yang)經認可(ke)(ke)(ke)后(hou)，正式定點放線(xian)。（3）播(bo)(bo)種(zhong)(zhong)(zhong)(zhong)：根據種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)量(liang)的(de)(de)(de)多少，和植(zhi)物的(de)(de)(de)特性，可(ke)(ke)(ke)采(cai)用撒播(bo)(bo)法、條(tiao)(tiao)播(bo)(bo)法、點播(bo)(bo)法等。播(bo)(bo)種(zhong)(zhong)(zhong)(zhong)量(liang)一般根據種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)發芽率、氣候(hou)、土質及幼苗生(sheng)長(chang)速度而定。大粒種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)覆(fu)土厚度約為種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)直徑的(de)(de)(de)2—3倍，小粒種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)覆(fu)細土，以(yi)(yi)不(bu)見種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)為度；細粒種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)也可(ke)(ke)(ke)不(bu)覆(fu)土，播(bo)(bo)種(zhong)(zhong)(zhong)(zhong)后(hou)將(jiang)床面(mian)(mian)壓實，使種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)與土壤(rang)緊密(mi)接觸，便于種(zhong)(zhong)(zhong)(zhong)子(zi)(zi)(zi)由土壤(rang)中吸收(shou)水分(fen)(fen)發芽。床面(mian)(mian)壓住后(hou)及時(shi)覆(fu)蓋(gai)生(sheng)態(tai)護(hu)(hu)坡毯(tan)，以(yi)(yi)利保(bao)育(yu)。（4）鋪設(she)(she)生(sheng)態(tai)護(hu)(hu)坡毯(tan)：使用時(shi)，如同鋪地毯(tan)一樣(yang)(yang)，將(jiang)草(cao)毯(tan)覆(fu)蓋(gai)于播(bo)(bo)種(zhong)(zhong)(zhong)(zhong)后(hou)的(de)(de)(de)土壤(rang)上(shang)，并用竹簽或鉛絲固定，防止生(sheng)態(tai)護(hu)(hu)坡毯(tan)脫落(luo)或被風(feng)刮開。（5）養護(hu)(hu)：種(zhong)(zhong)(zhong)(zhong)植(zhi)后(hou)應澆透(tou)水，以(yi)(yi)后(hou)要(yao)根據天(tian)氣情況(kuang)、自(zi)然條(tiao)(tiao)件和草(cao)種(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)種(zhong)(zhong)(zhong)(zhong)類(lei)而定，如沒(mei)有養護(hu)(hu)條(tiao)(tiao)件也可(ke)(ke)(ke)以(yi)(yi)零養護(hu)(hu)。

生(sheng)態護坡毯覆蓋地(di)表(biao)后(hou)，能有效的(de)防(fang)止風、熱、水(shui)(shui)、冷、鹽(yan)堿等(deng)不(bu)利因素對土(tu)壤(rang)的(de)侵(qin)蝕，起到物理(li)防(fang)護作用。可提高植(zhi)物的(de)成活(huo)率、對植(zhi)物的(de)保護效果顯著。生(sheng)態護坡(po)毯(tan)環保性強，易于固定，鋪設迅速，每人每天可鋪設千余(yu)平方米。生(sheng)態護坡(po)毯(tan)自身吸水(shui)(shui)、儲水(shui)(shui)性好，被狀結構可以減少地(di)表(biao)水(shui)(shui)的(de)蒸發(fa)，生(sheng)態護坡(po)毯(tan)改(gai)變(bian)土(tu)壤(rang)的(de)溫度(du)和濕度(du)，積聚(ju)腐殖質，提高土(tu)壤(rang)墑情(qing)，改(gai)良貧瘠土(tu)壤(rang)。
