在大田苗床上分别进行了马尾松芽苗定距移栽不同切根处理、不同时间切根、不同深度切根等试验研究 ,试验结果表明 :切不切根 (包括切胚根 )、切根次数 ,以及切根时间、切根深度等均对苗木质量和生长状况有显著性影响 ;以芽苗定距移栽 3次切根苗木质量最优 (侧根数达14 .5条 /株 ,侧根生物量 1.2 5g/株 ,高径比 74∶ 1,地径 0 .2 6 cm) ,其次是 2次切根 ,;切主、侧根时间以 8月底和 9月初为宜 ;切根深度以 8~ 10 cm为最优
Masson seedlings in the field were cut and transplanted Masson pine seedlings different root cutting treatment, cutting at different times, different depths of root cutting and other experimental studies show that: cut not cut root (including cut radicle), cut root The number of cuttings and the rooting depth had significant effects on the quality and growth of nursery stock.The quality of cuttings with transplanting three times a day was the best (the number of lateral roots was 14.5 / plant, the lateral roots Biomass 1.2 5g / strain, height-diameter ratio of 74: 1, diameter 0.226 cm), followed by 2 times of cutting; cutting the main, lateral rooting time in late August and early September is appropriate; cutting depth to 8 ~ 10 cm is the best
