造林密度对中华猕猴桃枝条产量及经济效益的影响

2012年11月于安徽省泾县桃花潭镇苏岭村对5种不同造林密度的中华猕猴桃林枝条生长量与产量以及经济效益进行研究。结果表明:造林密度对中华猕猴桃2年生枝条基部直径、单株产量、单位面积产量影响显著,对枝条长度的影响较小;造林密度越小,枝条平均基部直径越粗,单株产量也越高;5种造林密度的猕猴桃林单位面积枝条产量大小为C(2 m×1.66 m)D(2 m×1.45 m)B(2 m×2 m)E(2 m×1.25m)A(2 m×2.4 m)。造林与抚育管理成本与造林密度成正比,造林密度越大,成本越高;总收入、纯利润与造林密度呈抛物线关系;当造林密度为2 m×1.66 m时,其2年生生枝条总产量最高,经济效益最大。

Effect of afforestation density on yield and economic benefit of Actinidia chinensis branches

In November 2012 in Taohuatan township Suling village of Jingxian County in Anhui Province,the branches growth and yield and economic benefit of Actinidia chinensis with five afforestation density were studied. The results showed that,afforestation density had significant effect on the base diameter of Actinidia chinensis 2 years old branches, single branch yield and yield per unit area,but small effect on the length of branches. The smaller the afforestation density,the larger the branches average base diameter,also,the higher single branch yield. The yield per unit area of five kinds of afforestation density was C（ 2 m × 1. 66 m） ＆gt; D（ 2 m × 1. 45 m） ＆gt; B（ 2 m × 2 m） ＆gt; E（ 2 m × 1. 25 m） ＆gt; A（ 2 m × 2. 4 m）. Afforestation and tending management cost was proportional to the afforestation density,afforestation density the greater the cost was higher. Afforestation density and total income,net profit was parabola relationship. When afforestation density was 2 m × 1. 66 m,the total output and economic benefit of Actinidia chinensis 2-year-old branches was the largest.
