摘要
为探究不同施肥方案对油茶及其果实的生长及产量的影响.以都匀市国有平浪林场为试验地点,设置有机肥和复合肥2种肥料处理,0.60、0.80、1.00 kg/(株·a)3种施肥量,对不同施肥方式下油茶及其果实的生长情况和品质状况进行评估,比较了不同施肥方案对油茶及其果实产量和品质的影响.结果表明:处理组B2油茶及其果实的品质和产量相对较好,其株高、冠幅、地径、产量相较于对照组分别提高了:35.58％、49.46％、56.85％、63.96％;油茶果实的单果尺寸、单果质量、鲜果含油率、种仁含油率、干出仁率、干出籽率相较于对照组分别提高了:35.51％、85.85％、33.98％、32.09％、15.97％、34.17％.试验结果可为油茶的科学施肥提供理论依据.
Abstract
To explore the effects of different fertilization schemes on the growth and yield of Camellia oleifera A-bel.and its fruits,this study used the State-Owned Pinglang Forest Farm in Duyun City as the experimental site,and set up two types of fertilizer treatments,organic fertilizer and compound fertilizer,with three fertilization a-mounts of 0.60,0.80,1.00 kg/(plant·a).The growth and quality of Camellia oleifera Abel.and its fruits under different fertilization methods were evaluated,and the effects of different fertilization schemes on the yield and quality of Camellia oleifera Abel.and its fruits were compared.Result:The quality and yield of treatment group B2 Camellia oleifera Abel.and its fruits were relatively good,with plant height,crown width,ground diameter,and yield increased by 35.58％,49.46％,56.85％,and 63.96％compared to the control group,respectively;Com-pared with the control group,the single fruit size,single fruit quality,fresh fruit oil content,kernel oil content,dry kernel yield,and dry seed yield of Camellia oleifera Abel.fruits increased by 35.51％,85.85％,33.98％,32.09％,15.97％,and 34.17％,respectively.This study provides a theoretical basis for the scientific fertilization of Camel-lia oleifera Abel..
