通过对异地试验跟踪调查,在药剂蘸浆造林成本核算、产值分析和药剂经济效益估算的基础上,利用投入产出分析方法,结合林木鼠(兔)害治理规律,对药剂蘸浆造林投入产出效益进行了研究。结果表明,用技术贡献率、投入产出比、投资收益率和投资回收期指标进行药剂蘸浆造林效益分析。产值贡献率NPA>RPA,油松>侧柏。经济效益贡献率,定植当年米脂和麟游县的NPARPA,定植3aNPA>RPA;油松<侧柏。统计投入产出比侧柏>油松,NPA>RPA>CK;效益投入产出CK>RPA>NPA,系数CK侧柏。投资收益率NPA>RPA,定植当年油松>侧柏,定植3a油松<侧柏。药剂处理投资回收期比对照明显缩短。
Based on the follow-up investigation of off-site tests, on the basis of cost accounting, output value analysis and medicament economic benefit evaluation of pesticide dip-leaching and afforestation, the input-output analysis method and the law of forest tree rat (rabbit) Outcomes were studied. The results showed that the profitability of pesticide dip in afforestation was analyzed by technical contribution rate, input-output ratio, return on investment and payback period. The contribution rate of NPA> RPA, Pinus tabulaeformis> Arborvitae. The contribution rate of economic benefits, NPA RPA in pagoda area, colonization 3aNPA> RPA in Mianzhi and Linyou County in the year of planting; Pinus tabulaeformis; The statistic inputs and outputs were higher than that of Platycladus orientalis> Pinus tabulaeformis, NPA> RPA> CK; CK> RPA> NPA, coefficient CK RPA, Pinus tabulaeformis Planting> Platycladus orientalis 3a Pinus tabulaeformis Platycladus orientalis. Pharmacy treatment payback period was significantly shorter than the control.
