摘  要:
在江淮丘陵地区首次较大规模引进薄壳山核桃的育苗过程中,为提高引种成功率和苗木生长量,在种子处理、土壤改良和苗期管理等方面采取了不同的技术措施,并分析不同处理因素对苗高、地径、树冠生长及成苗率的影响。初步研究结果表明:在粘盘黄棕壤为主的江淮丘陵地区,可以进行薄壳山核桃引种育苗;土壤改良有利于提高苗木生长量;间隔不长的不同播种时间对苗木生长没有显著影响;同批次的大粒种子生长量比小粒种子大。

摘  要:
In the process of seedling production of massively introduced Carya illinoensis in Yangtze-Huaihe hilly region of Anhui for the first time,different technical measures regarding the seed treatment,soil improvement and seedling tending etc.,were taken to ensure the successful introduction and improve the seedling growth.The effects of different treatment factors on seedling growth in height,basal diameter and crown and seedling survival rates were analyzed.Preliminary results showed that in Yangtze-Huaihe hilly region of Anhui with sticky yellow-brown soil as its zonal soil,Carya illinoensis could be introduced and grown.Soil improvement helped improve the seedling growth.Different sowing times with short intervals did not affect the seedling growth significantly.In the same batch of seeds,larger ones grew better than smaller ones.
