项目现场查定专家组意见表

2021年6月19日科技部农村中心组织专家组队项目现场查定的意见。在广西壮族自治区北流市大伦镇建立了松脂高效栽培标准示范基地1个，面积4005.5亩。针对马尾松配方施肥和密度调控等技术试验示范林，对大伦镇玉塘村大坪组金猫岭的12年生马尾松未施肥和施肥林各随机抽取15株测产，经测算后，得出5月19日-6月19日施肥林平均单株产脂量0.166kg，未施肥林平均单株产脂量0.088kg。

On June 19, 2021, the Rural Development Center of the Ministry of Science and Technology organized an expert panel to conduct on-site inspection and assessment for the project, and released the corresponding inspection opinions. A standard demonstration base for efficient cultivation of pine resin was established in Dalun Town, Beiliu City, Guangxi Zhuang Autonomous Region, with a total area of 4005.5 mu. For the experimental demonstration forests adopting technologies including formulated fertilization and density regulation of Pinus massoniana, 15 trees were randomly selected from each of the 12-year-old Pinus massoniana stands with and without fertilization at Jinmaoling, Daping Group, Yutang Village, Dalun Town for yield testing. Through calculation and analysis, it was determined that during the period from May 19 to June 19, the average resin yield per tree of the fertilized stands was 0.166 kg, while that of the unfertilized stands was 0.088 kg.
