本文是对位于杭州的中国农科院茶叶研究所进行的10年种植密度试验的经济分析。试验所用的无性系品种是龙井43,设4个不同密度处理。在密植的情况下,产量是浙江省一般茶园的10倍以上。用专门的计算机软件检查了如下常规的投资指标:净现值总和,永久性年金,收益成本比,内部报酬率,以及贴现后的资本回收期;此外,还计算了各种种植密度的最佳修剪时间,并采用各种茶农生产中出现的假设进行了敏感性分析。结果表明,种植密度为12000株/亩具有最佳的经济效果。
This article is an economic analysis of the 10-year planting density test conducted by the Tea Research Institute of Chinese Academy of Agricultural Sciences in Hangzhou. The clones used in the experiment were Longjing 43, which were treated at 4 different densities. In the case of close planting, the output is more than 10 times of the average tea garden in Zhejiang Province. The following general investment metrics were examined using specialized computer software: sum of net present value, perpetual annuity, cost-benefit ratio, internal rate of return, and capital payback period after discounting; in addition, the best of various planting densities Trim the time and conduct a sensitivity analysis using the assumptions that occurred in various tea farmers. The results showed that planting density of 12000 plants / acre has the best economic effect.
