在田间苗圃采用全光播种育苗方式进行桤木种子不同覆盖方式、不同密度的对比试验，结果表明：不同覆盖方式对种子发芽率的影响极为显著，以谷皮+塑料小拱棚的发芽率最高，达51.5%；不同苗木密度对苗木质量的影响极为显著，以株行距8 cm×8 cm最为适宜，合格苗产量最高，达89.40万株/hm2。
在田間苗圃採用全光播種育苗方式進行榿木種子不同覆蓋方式、不同密度的對比試驗，結果錶明：不同覆蓋方式對種子髮芽率的影響極為顯著，以穀皮+塑料小拱棚的髮芽率最高，達51.5%；不同苗木密度對苗木質量的影響極為顯著，以株行距8 cm×8 cm最為適宜，閤格苗產量最高，達89.40萬株/hm2。

The contrast tests of different covering methods and different density of Alnus cremastogyne Bark seeds were carried out using all-optical sowing method ,the results showed that ,different covering methods had significant effects on the germination rate of seeds ,the germination rate of the bran+plastic small arch shed was highest ,up to 51.5%.Effects of different seedling wood density on seedling quality were extremely significantly , the spacing 8 cm×8 cm was most appropriate,the yield of qualified seedling was the highest,up to 894 000 line/hm2.
