娜塔栎品(pin)种(zhong)特性:一(yi)，高(gao)大(da)(da)落叶乔木(mu)，世界上著名的(de)(de)(de)景观彩色树(shu)种(zhong)。二，有(you)(you)很好(hao)的(de)(de)(de)耐(nai)旱(han)，耐(nai)水，耐(nai)高(gao)温，耐(nai)瘠薄，抗病虫害性能，是(shi)平原低洼地(di)，贫(pin)瘠地(di)造林(lin)的(de)(de)(de)首选树(shu)种(zhong)。三，主根(gen)深(shen)测根(gen)长(zhang)(zhang)树(shu)体稳当(dang)可做防风林(lin)树(shu)种(zhong)。此外。每年果实产量大(da)(da)，橡子富含(han)淀粉(fen)，在现(xian)代森林(lin)和景观中，它是(shi)动物们的(de)(de)(de)食(shi)物来(lai)源与(yu)野生动物息(xi)息(xi)相(xiang)关，形成(cheng)持(chi)续稳定的(de)(de)(de)生态(tai)系统(tong)，讲死林(lin)子变成(cheng)活森林(lin)，在维护生态(tai)系统(tong)持(chi)续发(fa)展和生物圈食(shi)物链方面有(you)(you)重要(yao)的(de)(de)(de)意义。需要(yao)注意的(de)(de)(de)不(bu)足。一(yi)是(shi)不(bu)耐(nai)盐碱，临海的(de)(de)(de)盐碱地(di)生长(zhang)(zhang)不(bu)良。比如(ru)崇(chong)明岛的(de)(de)(de)大(da)(da)部分(fen)地(di)区不(bu)太(tai)适宜(yi)种(zhong)植。会出现(xian)叶子黄化(hua)长(zhang)(zhang)不(bu)大(da)(da)等现(xian)象。二是(shi)乔木(mu)的(de)(de)(de)生长(zhang)(zhang)必须(xu)有(you)(you)适宜(yi)的(de)(de)(de)土(tu)壤与(yu)空间，栽种(zhong)时土(tu)球要(yao)大(da)(da)，胸(xiong)径与(yu)土(tu)球比例不(bu)少于1:8-10，穴位要大，回(hui)填的土壤要含有机质，不然生(sheng)长(zhang)较慢，影响(xiang)景观(guan)升级(ji)。三是本(ben)品种最适合华东，江(jiang)浙沪，长(zhang)三角地区，注意品种纯度，沼生(sheng)栎，舒玛栎不易分辩(bian)，应(ying)尽量(liang)就近取苗，保成(cheng)活(huo)率，快速恢复生(sheng)长(zhang)。
