| 摘 要： | 在沙地针叶树播种时使用"科瀚98"、FA旱地龙2种抗旱节水制剂,分别采用浸种和拌种进行种子不同处理试验,结果表明,4种处理在不同程度对不同苗木的生长有促进作用,同时促进了樟子松、油松苗木的干物质累积;同时,在一定程度上减轻土壤的酸化,增加土壤有机质,提高土壤的肥力和蓄水力,增加抗旱节水、增效节支作用.建议在沙区针叶树育苗中根据实际情况推广应用. |

| Abstract: | 2 kinds of anti-drought and water-saving agents Kehan 98 and FA Handilong were used in sowing on sandy fields for coniferous trees,and such different seed treatments as seed soaking and seed dressing were conducted.The results indicated that: 4 treatments had promotion effects on growth of seedlings to some extents and promoted accumulation of dry matters of Pinus sylvestris var.mongolica and Pinus tabulaeformis at the same time,and lessened soil acidification and increased soil OM,fertility and water storing capacity,enhanced the effects of anti-drought and water-saving and increasing efficient and reducing expenditures eventually,which should be popularized and used in seedling cultivation of coniferous trees on sandy fields in line with the actual practice. |
| Keywords: | anti-drought and water-saving agents sandy fields coniferous trees sowing seedling cultivation |
