培育措施对华山松果材兼用林生长和果实产量的影响

分析了不同培育措施(土壤类型、整地方式、造林方式、造林密度、林分结构、营林措施)对华山松果材兼用林生长和果实产量的影响.结果表明:不同土壤类型、造林密度、林分结构和营林措施对华山松的树高、胸径、冠幅和果实产量的差异都达到极显著水平;不同整地方式和造林方式对华山松的树高、胸径、冠幅、枝下高及果实产量的差异都不显著.在此基础上,初步总结出营建华山松果材兼用林的关键技术措施.

Effect of different silvicultural measures on growth and fruit yield of Pinus armandi Franch fruit and timber forest

Effect of different silvicultural measures(soil type,site preparation modes,plantation modes,planting density,stand structure,forestry measures) on the growth and fruit yield of Pinus armandi Franch fruit and timber forest were analyzed.The results showed that their variances of different soil type,planting density,stand structure,forestry measures on tree height,diameter at breast height(DBH),crown width and fruit yield of Pinus armandi Franch are extreme remarkable,different site preparation modes and plantation modes on tree height,diameter at breast height(DBH),crown width,clear bole height and fruit yield of Pinus armandi Franch are not remarkable.On the bases of above study,series of key silvicultural technical measures on fast growth and high yield of Pinus armandi Franch fruit and timber forest were put forward.
