摘  要：
为了缩短薄壳山核桃砧木的出圃时间,提高其嫁接成活率,就薄壳山核桃大颗粒种子与小颗粒种子、种子的不同贮藏方法、不同胚根尖与容器处理、不同截根处理与施肥浓度对1年生薄壳山核桃实生苗的高度与地径生长的影响情况进行了对比试验。结果表明:种子大小对苗木的地径和高度均有较大的影响,在育苗过程中,应优先选择颗粒饱满的大粒种子进行育苗;用湿沙贮藏的种子其发芽率比干藏的高8.4%;不同育苗容器、不同施肥浓度对苗木生长量有明显的影响;不同胚根处理方法对苗木生长量也有影响,但影响不明显;不同截主根措施对苗木生长量的影响很大,不截主根苗的苗高和地径比截主根苗分别高97.68%与26.32%。并结合试验结果与生产经验总结提出了薄壳山核桃优质砧木苗培育的主要技术要点。

摘  要：
In order to shorten the cultivation time of rootstock in Carya illinoensis,and to improve the survival rate of grafting,effects of some factors on height and ground diameter of C.illinoensis seedlings were analyzed,for example,the seed size,seed storage,seed treatment before sowing and concentration of fertilizer.The results showed that seed size had great effect on ground diameter and height of seedling.In the processing of seedling culture,plump seeds should be choosed in preference.Germination rate of seed storaged in wet sand was 8.4% higher than in dry sand.Different containers and concentrations of fertilizer had significant effect on increment of seedling.Different treatments of radicle had not any insignificant effect on increment of seedling.Different treatments of cutting main root had insignificant effect on increment of seedling.Height and ground diameter of the seedlings with main roots was 97.68% and 26.32% higher than that with main roots,respectively.The cultivation techniques of fine rootstock in C.illinoemis were summarized based on the results and production experience.
