摘要
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。
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.
