摘要
为探明施肥对平欧杂种榛干物质积累及树体生长的影响,对辽宁省大连市金普新区(辽宁省经济林研究所)科研示范基地与抚顺市顺城区门进村榛子试验示范基地栽植的平欧杂种榛(达维、辽3)开展了施肥试验.结果表明:施肥与不施肥树体的平均总生物量分别为5 987.24 g和3 867.11 g,施肥后两试验地的榛子平均产量分别为4 480.5和4 515.0 kg·hm-2.施肥对树体生长有较明显的影响,也提高了 土壤中氮、磷、钾及有机质和微量元素含量,对丰产起到积极作用.
Abstract
In order to explore the effects of fertilization on dry matter accumulation and tree growth of Corylus het-erophylla × Corylus avellana,the fertilization experiment was carried out on Corylus heterophylla × Corylus avel-lana(Dawei,Liao 3)planted in the scientific research demonstration base of Jinpu New District(Economic Forest Research Institute of Liaoning Province)in Dalian City of Liaoning Province and the hazelnut experimental demon-stration base of Menjin Village in Shuncheng District of Fushun City.The results showed that the total biomass of fertilization and non-fertilization trees reached 5 987.24 g and 3 867.11 g,respectively.After fertilization,the aver-age yields of hazelnut in the two experimental sites were 4 480.5 and 4 515.0 kg·hm-2,respectively.Fertilization had a significant effect on tree growth,and also increased the contents of nitrogen,phosphorus,potassium,organic matter and trace elements,which played a positive role in high yield.
