| 摘 要： | 通过对华北落叶松避光遮荫育苗、灌水降湿育苗和锯末覆盖育苗等3种方法育苗效果的调查及分析,结果表明:避光育苗法资金投入较大,不宜采用,其他2种方法产合格苗数量差异极显著,灌水育苗每677 m2产合格苗11.8万株,锯末覆盖法产合格苗21.3万株。得出锯末覆盖法是华北落叶松最佳育苗方法的结论。

| Abstract: | Investigations and analyses about 3 seedling-raising ways(shading,irrigation and colling down,mulching with sawdust) on Larix principis-rupprechtii were conducted.The results showed that the bankroll input of shading ways was bigger and not be adopted.The amount of qualified seedlings had significant differences by using other 2 ways.11.8 ten thousand trees per 667m2 were produced by using irrigation way and 21.3 ten thousand trees were produced by using mulching with sawdust way.The conclusion was gotten out that mulching with sawdust was the optimal seedling-raising method of Larix principis-rupprechtii. |
