用I-214杨短轮伐期杨树采伐木梢头进行深栽造林试验,与2年生大苗截根深栽和常规造林比较,梢头深栽在成活率、树病及胸径生长等方面效果都较好。梢头深栽成功的关键是选用幼年(4—7年)、生长旺盛和健康的采伐木梢头和深栽入地下水中。
The results of deep-plantation experiments on poplar cuttings with I-214 short rotations were compared with those of two-year-old seedlings with deep-rooted cuttings and conventional reforestation. The results showed that the shrubs were better in survival rate, tree disease and DBH growth . The key to the successful plantation is the selection of juveniles (4-7 years), vigorous growth and healthy harvesting of wood shoots and deep planting in groundwater.
