通过对麻栎栽培过程中不同技术措施的对比试验,研究了麻栎在造林时的最优初植密度、最适合苗木和最佳更新方式等麻栎栽培技术,结果表明:麻栎初植密度以4440株hm -2和3330株hm -2为宜;造林时应用Ⅰ、Ⅱ级苗可显著提高造林成活率和保存率;最佳更新方式为萌蘖更新,更新后胸径与树高的5年生长量比植苗和播种分别提高27.3%、51.1%和31.1%、56.7%。
通過對痳櫟栽培過程中不同技術措施的對比試驗,研究瞭痳櫟在造林時的最優初植密度、最適閤苗木和最佳更新方式等痳櫟栽培技術,結果錶明:痳櫟初植密度以4440株hm -2和3330株hm -2為宜;造林時應用Ⅰ、Ⅱ級苗可顯著提高造林成活率和保存率;最佳更新方式為萌蘗更新,更新後胸徑與樹高的5年生長量比植苗和播種分彆提高27.3%、51.1%和31.1%、56.7%。

Through comparative experiments of cultivating Quercus acutissima ,the optimum planting density ,seed‐lings and regeneration mode of seedlings of cultivating Quercus acutissima were studied .Result shows that :the op‐timal planting density of Quercus acutissima are 4 440 trees hm -2 and 3 330 trees hm -2 ;applying Ⅰ & Ⅱ‐grade seedlings of Quercus acutissima can significantly improve the survival rate and preservation rate;the optimal regen‐eration mode is sprout regeneration ,5‐year growth of DBH & tree height for Quercus acutissima increase by 27.3% ,51 .1% & 31 .1% ,56 .7% than that of planting and seed sowing .
