武陵山中部区域油茶基地投产表现情况研究

Study on the Performance of Camellia oleifera Base in the Central Region of Wuling Mountain

摘要:

为科学评估武陵山中部区域投产油茶基地产量与抗性表现情况，以来凤县5个投产油茶基地样本为研究对象，对其良种率、病虫害发生率与发生程度进行调查，对其果实产量进行测定分析。结果表明：良种油茶单株平均果实产量和单位面积冠幅果实产量要高于非良种油茶，其中尤以‘长林53号’油茶良种表现最好，理论亩产油量可达82.14 kg;较高的良种率可显著提高油茶果实产量，1号高良种率试验样地平均单位面积冠幅果实产量是4号低良种率试验样地的59.5倍，高良种率可显著降低病害发生率与病害发生程度。据此对武陵山区油茶种植与研究提出建议，为油茶栽培提供参考。 标签：

Abstract:

In order to scientifically evaluate the yield and resistance performance of Camellia oleifera bases in the central region of wuling mountain, focused on five Camellia oleifera bases in Laifeng County as research samples.The rate of superior seedlings, incidence rate, and severity of diseases and pests were investigated, and the fresh fruit yield was measured and analyzed.The results showed that the average yield per plant and per unit area of superior seedling Camellia oleifera were higher than non-superior seedling Camellia oleifera.Among them, ‘Changlin 53' clone exhibited the best performance as a superior seedling, with a theoretical yield of 82.14 kg.A higher rate of superior seedlings significantly increased the fresh fruit yield of Camellia oleifera.The average per unit area yield in the experiment plot with a high rate of superior seedlings was 59.5 times that of the experiment plot with a low rate of superior seedlings(Experiment 1 vs.Experiment 4).A higher rate of superior seedlings also significantly reduced the incidence rate and severity of diseases, providing recommendations for Camellia oleifera cultivation and research in the Wuling Mountain area.
