正确评估药剂蘸浆造林成本是科学使用植物抗逆剂的前提。通过对异地试验跟踪调查,采用成本核算法,分析了药剂蘸浆造林各项成本变化。结果显示:对照区、纳米型植物抗逆剂和多效抗旱驱鼠剂(RPA)处理区油松蘸浆造林总成本依次为(7 077.45±404.84)元·hm-2、(7 238.11±406.48)元·hm-2和(7 242.20±386.21)元·hm-2,侧柏为(5 435.10±394.83)元·hm-2、(596.69±411.88)元·hm-2和(5 635.57±422.21)元·hm-2。与对照差异不显著;而地区间、树种间和药剂间差异显著或极显著。油松和侧柏用工成本占总成本比重为58.37%±0.64%和80.00%±1.64%,种苗成本比重为39.60%±0.69%和17.97%±1.53%,树种间差异极显著;用工和种苗成本是控制药剂蘸浆造林总成本的关键因素,可以通过提高机械造林和工厂化育苗程度降低造林成本。
It is a prerequisite for scientific use of plant anti-retrogradation to correctly evaluate the cost of pesticide dip in afforestation. Through the follow-up survey of off-site tests, the cost accounting method was used to analyze the cost changes of pesticide dip in afforestation. The results showed that the total cost of Pinus tabulaeformis diphtheria afforestation in the control area, nano-plant resistance agent and RPA treatment area was (7 077.45 ± 404.84) yuan · hm-2, (7 238.11 ± 406.48) ) And the arborvitae were (5 435.10 ± 394.83) Yuan · hm-2, (596.69 ± 411.88) Yuan · hm-2 and (5 635.57 ± 422.21) · hm-2 and (7 242.20 ± 386.21) ) Yuan · hm-2. There was no significant difference with the control; however, there was significant or extremely significant difference among the species, species and medicaments in different regions. The proportion of labor cost to the total cost of Pinus tabulaeformis and Platycladus orientalis was 58.37% ± 0.64% and 80.00% ± 1.64% respectively, and the proportion of seedling cost was 39.60% ± 0.69% and 17.97% ± 1.53% respectively. The cost of seedling is a key factor in controlling the total cost of pesticide dip and afforestation, which can reduce the cost of afforestation by increasing the degree of mechanical afforestation and factory nursery.
