摘　　要：为探索播种时间、裸根苗套袋及拉枝角度对皖南地区薄壳山核桃苗木生长的影响,以不同品种和树龄的薄壳山核桃为试验材料,对比不同播种时间、裸根苗整株套袋处理、拉枝角度等处理中薄壳山核桃的生长量、成活率、结果短枝数量。结果表明:(1)冬播覆膜对种子出苗率无显著影响,对幼苗生长量有显著影响,冬播覆膜措施下的1年生苗地径比春播粗2.18 mm,苗高比春播高38.5 cm;(2)薄壳山核桃裸根苗移栽整株套袋处理的成活率与对照组间存在显著差异,整株套袋提高了裸根苗移栽的成活率;(3)薄壳山核桃拉枝角度为45°时与拉枝角度65°、85°和105°处理的平均结果短枝数均存在显著差异,拉枝角度在85°时结果短枝数最多。即薄壳山核桃冬播生长量比春播生长量大,裸根苗移栽套袋处理的成活率增加,拉枝角度处于85°短枝数最多。In order to explore effects of sowing time,bagging bare-root seedlings,and branch-pulling angle on growthof Carya illinois seedlings,using different cultivars of C.illinois at different ages as experimental materials,increment,survival rate and fruiting short branch number in C.illinois were compared in treatments of different sowing time,wholeplantbagging of bare-root seedlings,and branch-pulling angles.The results showed that:(1)Winter sowing and filmmulching had no significant effect on seed emergence rate,but it had significant effects on seedling increment.Grounddiameter of one-year-old winter-sowing seedlings was2.18mm higher than that of spring-sowing seedlings,and seedlingheight was38.5cm higher than that of spring-sowing seedlings.(2)Survival rate of bare-rooted C.illinois seedlings inwhole-plant bagging treatment was significantly different from that of control,and whole-plant bagging increased thesurvival rate of transplanted bare-root seedlings.(3)Average fruiting short branch number of C.illinois in branch-pullingangle45°treatment had significant differences with those in branch-pulling angle65°,85°and105°treatments,and itwas the most in branch-pulling angle85°.So increment of winter-sowing seedlings was more than that spring-sowingseedlings,bagging treatment could increase survival rate of transplanted bare-rooted seedlings,and number of shortshoots was the most in the branch-pulling angle85°treatment.
