摘　　要：以2008年3月营造的省级湿地松良种0-609家系林分为研究对象,对间伐后林分开展施用硫酸钾复合肥与施用GGR6促脂试验。结果表明:施用硫酸钾复合肥与施用GGR6的湿地松林分与对照林分的松脂产量差异达极显著水平(P<0.01),施用硫酸钾复合肥与施用GGR6生长调节剂对湿地松林分具有显著的促脂作用。试验中最佳单株施肥量为300 g,最佳GGR6施用量为1/20000的水溶液2 kg·株^(-1),松脂产量可提高27%以上。This experiment took the stand built by 0-609 families of provincial slash pine improved varieties in March 2008 as the research object,and carried out fertilization(potassium sulfate compound fertilizer)and application of GGR6 to promote fat test on the stand after thinning.The results showed that the pine resin yield of Pinus elliottii stand treated with fertilizer and GGR6 was significantly different from that of the control stand(P<0.01).The application of potassium sulfate compound fertilizer and GGR6 growth regulator had a significant lipid promoting effect on Pinus elliottii stand.In the experiment,the best fertilization amount per plant was 300 g·plant^(-1),and the best GGR6 was 2 kg·plant^(-1)of 1/20000 aqueous solution.The yield of turpentine can be increased by more than 27%.
