摘要 针对大树反季节移栽成活率欠佳的状况,在反季节移栽过程中对几种常见树种开展了起挖前、后喷施抑制蒸腾剂的对比试验。结果表明,起挖后喷施抑制蒸腾剂,对各树种恢复无影响;起挖前喷施抑制蒸腾剂,对各树种恢复有影响,纸质叶片树种抑制蒸腾剂喷施浓度以200mg/L为好,蜡质叶片树种抑制蒸腾剂喷施浓度以300mg/L为好。栽植深度试验表明,保持栽植后浇水前土球高于地面10~15cm为好。 In view of the poor survival rate of large trees planted off-season,a comparative experiment was carried out on several common tree species by spraying antitranspirant before and after digging during the off-season transplanting process.The results showed that spraying antitranspirant after digging had no effect on the recovery of various tree species,spraying antitranspirant before digging has an impact on the recovery of various tree species.The suitable concentration of antitranspirant for papery leaf tree species was 200mg/L,and that for waxy leaf tree species was 300mg/L.The experiment of planting depth showed that it was better to keep the soil ball 10-15cm above the ground before watering after planting.
