辽东桤木种子育苗技术研究

[目的]研究辽东桤木种子育苗的各个技术措施。[方法]采用不同播种量、不同播种方式、不同播种时间和不同覆盖物探讨对辽东桤木种子出苗的影响。[结果]播种量5g/m2、条播或撒播、4月25日～5月5日播种和只盖锯木屑再压少许河砂的出苗较快,出齐苗时间短,出苗数量适中。[结论]辽东桤木种子经100mg/LGA3溶液浸泡48h,以播种量5g/m2、于4月下旬～5月初采用条播或撒播、覆盖锯木屑再压少许河砂为宜。

Study on Techniques of Raising Seeding for Alnus sibirica

[Objective]The aim was to study the techniques of raising seeding for Alnus sibirica.[Method]The influence were researched by different seeding quantities,seeding methods,seeding time and overlay for raising seeding on Alnus sibirica.[Result]The seeds were emerged rapidly,the time for erupting completely seeding was short,the number of emergence was moderate under the seed quantity was 5 g/m2,strip or spread,seeding in April 25th to May 5th.covering wooden meal and sand.[Conclusion]The seeds of Alnus sibirica were soaked in 100 mg/L GA3 solution 48 h,the seed quantity was 5 g/m2,the seeding time was in the last third of April to in the first ten days of May,the seeding method was strip or spread and cover wooden meal and sand were well for raising seeding on Alnus sibirica.
