【摘要】 以杉木组培容器苗为材料,进行不同基质和不同月份、不同施肥措施等处理对组培苗木生长影响的试验。结果表明,杉木组培生根瓶苗全年每月均可以移栽,但不同的月份因气候条件有别,苗木移栽成活率不一致,苗木移栽最好的时间是5月和11月,成活率分别为97.6%和97.7%,最低的是8月,仅86.8%;选用红心土或30%红心土+70%椰糠做基质,苗木移栽成活率高达96.3%以上,苗木根系发达,生长良好;采用芬兰复合肥0.8%+尿素0.05%+氯化钾肥0.05%的混合肥料配比,对杉木组培苗生长效果良好,移栽培养120天,苗木平均高生长15.8cm,地径0.263cm,比对照的分别高260.3%和324.2%。更多还原

【Abstract】 Effects of matrix,season and fertilization on growth of tissue-cultured container seedlings after transplanting in Cunninghamia lanceolata was studied in this paper. Results showed that in vitro rooting seedlings were able to be transplanted in all seasons of a year,while transplantation survival percentage of seedlings was different with seasonal climate conditions. The best seedlings transplantation was in May and November,and transplantation survival percentage was 97. 6% and 97. 7%,respectively. The worst was in August,only being 86. 8%. The matrix made of red soil or 30% red soil+70% coir contributed to higher transplantation survival rate with 96. 3%,developed root system as well as good growth of seedlings. Application of fertilizer mixed with 0. 8% Finnish compound fertilizer+0. 05% urea+0. 05% KCl improved growth of tissue-cultured C. lanceolata seedling. By using this combination,the average of seedlings height and basal increment was 15. 8 cm and 0. 263 cm after 120 days of transplantation,which was 260. 3% and 324. 2% higher than that of the control.更多还原
