准确估测新造林林木产值是评价药剂蘸浆造林经济效益的基础。为此通过对异地试验跟踪调查,采用林木估价法对药剂蘸浆造林林木产值进行了研究。结果表明,药剂处理林木保存率比对照显著提高,差异极显著。苗高价格与苗高符合指数函数模型。定植当年对照与药剂处理区林木净产值和纯收益均为负值,产值小于造林成本。与对照相比,药剂处理区经济效益明显提高,林木产值、净产值和纯收益NPA>RPA>CK,差异极显著。
Accurately estimating the output value of newly reforestation trees is the basis for evaluating the economic benefits of pesticide dip in afforestation. To this end through the follow-up survey of off-site testing, the use of forest valuation method of pesticide dip pulp afforestation production value. The results showed that the preservation rate of medicinal plants was significantly higher than the control, the difference was significant. Miao high price and seedling height in line with the exponential function model. In the year of planting, the net value of net forest output and net income of the control and chemical treatment areas were negative, and the output value was less than the cost of afforestation. Compared with the control, the economic benefits of the pesticide treatment area increased significantly, and the difference was significant between the output value of forest products, net output value and NPA> RPA> CK.
