摘要:
注干施药技术是一种主动预防松材线虫病的技术。研究选取了浙江括苍山国家森林公园的黄山松Pinus taiwanensis 为研究对象,采用注干施药方法明确了2.3%(W/V)甲维盐对松材线虫病的预防效果,采用高效液相 色谱测定了注干施药1 a 和2 a 后黄山松不同组织部位中的甲维盐的残留量。结果表明,甲维盐注干施药对黄山松 林的松材线虫病防治效果显著,连续2 a 预防效果均达到100%;此外,建立了黄山松中甲维盐残留检测方法,枝 干中甲维盐的添加回收率超过80%,针叶中甲维盐的添加回收率超过90%,甲维盐分析方法满足残留检测要求; 注干后1 a,甲维盐在松树主干、侧枝及针叶中均维持着较高的残留浓度,其中在主干上的残留浓度最高处为29.95 mg·kg-1,在主干针叶中的残留浓度为8.46 mg·kg-1,第二年时,残留浓度降低,但在主干和侧枝内依然维持在1.00 mg·kg-1 以上。
Abstract:
Pinus taiwanensis stand in Kuocang Mountain of Zhejiang province were selected on January 31st, 2020 for experiment of trunk injection of Emamectin benzoate (EB) to control against pine wilt disease (PWD) caused by Bursaphelenchus xylophilus. In October 2020 and 2021, investigation was made on death rate of pine and EB residue after trunk injection. The result demonstrated that stand treated by injection in 2020 and 2021 had no death of trees, while the control (no injection) had death rate of 5.42% and 9.25%. Analysis on residues of EB in trunk, branch and needle of P. taiwanensis after 1 year of trunk injection resulted that the highest residue of EB in the trunk was 29.95 mg/kg, resudual in needle was 8.46 mg/kg. In 2021, EB residues decreased, but remained over 1.00 mg/kg the trunk, branch and needle.
