Abstract

Abstract:

In order to explore the effects of different slope planting on the growth and fruiting of Dongkui bayberry, the 15°, 28° and 43° slopes were selected on the 650 m altitude mountain in 2017. The results showed that the trunk thickness and tree height of 7-year-old bayberry planted on 15° slope increased by 8.12%-8.47% and 25.08%-29.24% respectively compared with those planted on 28° and 43° slopes, respectively. The 6-7-year-old bayberry grew faster and the crown diameter expanded faster when planted on 15° slope, while the trunk thickness increased relatively quicker when planted on 43° slope. The maturity period of 7-year-old bayberry trees planted on 43°slope land was the earliest, which was 1-3 days earlier than that of bayberry planted on 28° and 15° slope land, respectively. Compared with that planted on 28° and 15° slopes, the yield of 7-year-old bayberry planted on 43° slope increased by 50.00% and 87.72%, respectively. Compared with the bayberry planted on 15° slope, the single fruit weight of the 7-year-old bayberry planted on 43° slope increased by 19.13%. The soluble solids content of bayberry planted on 28° and 43° slopes were better, which were 1.27 and 1.45 percentage points higher than that on 15°slope, respectively. The total sugar content of bayberry planted on 28° and 43° slopes was 10.60% and 13.39% higher than that of bayberry planted on 15° slope, respectively, and the total acid content was 8.76% and 11.68% lower than that of bayberry planted on 15° slope, respectively. The sugar-acid ratios of bayberry planted on 28° and 43° slope were 12.63 and 13.38, respectively. The planting of slope land is conducive to the early maturity of Dongkui bayberry, the increase of plant yield, the increase of single fruit weight, and the increase of sugar-acid ratio, among which the Dongkui bayberry planted on 43° slope land has early fruit, large fruit shape and excellent quality, which can be popularized and applied in the planting of bayberry in mountainous areas.

Key words: bayberry, alpine planting, Dongkui, slope planting, yield, quality
