摘要
采取起垄覆盖地膜的方式,选用青皮核桃打孔直播,大方块形芽接法嫁接。结果表明:起垄覆盖地膜提高了地温,提早了出苗和嫁接时间,嫁接成活率达94%;嫁接时间以6月10日至7月10日为宜;20 cm×45 cm是实现快速育苗,达到1年出圃的最佳密度,且当年国标二级以上苗出圃率达90%。
The green seedcase walnut seeds were sowed directly and grafted with square budding by the method of ridging and film mulching in this study. The results showed that the seed germination and grafting were earlier than the control by the ridging and film mulching due to increasing the soil temperature and the grafting survival rate was reached 94%. The optimal time for grafting was from June 10 to July 10. The optimal density was 20cm x45cm for rapid propagation and the rate of nursery stock met National standards II was reached 90% .
