米槠造林措施与生长效应的初步研究

对14年生米槠试验林研究分析表明:挖大穴、回表土比简易挖穴平均胸径增长10.8%,蓄积量增长17.8%;施基肥比不施肥平均胸径增长9.4%,蓄积量增长14.5%;适当稀植比一般密度平均胸径增长12.1%。因此,采取必要的集约经营措施,能有效地促进米槠人工林速生丰产。

Preliminary study on the afforestation measure and growth effect of Castanopsis Carlessi

Based on studying on the experimental forest of 14-year-old Castanopsis Carlessi,the result showed that 10.8% increment in average DBH and 17.8% increment in volume occurred with digging the big holes compared to the simple holes;9.4% increment in average DBH and 14.5% increment in volume occurred with fertilized compared to the no fertilizer;and 12.1% increment with appropriate high density compared to the general density.In conclusion,the appropriate intensive farming measures will effectively promote Castanopsis Carlessi plantation rapid growth and high yield.
