摘要
本文对青钱柳MPT苗型(根坨苗)育苗技术进行了初步研究。研究表明用GA100mg·L^(-1)处理种子10h可使62%种子提早1年发芽,缩短了培育时间;采用128穴、72穴和50穴塑料穴盘培育青钱柳60d龄苗,进行两段育苗,移栽成活率100%;用泥炭、森林腐殖土、树皮粉、腐熟厩肥配制的营养基质均可提高根坨苗质量;用根坨苗造林,其造林成活率比裸根苗提高23.2%。
The MPT seedling cultivation technique for Cyclocarya paliurus （ Batal.） Iljinsk was studied. The results showed that 62% of the seeds treated with GA100mg · L^ - 1 for 10h germinated one year earlier than those of control. By the application of two stages growing seedling technique, the young seedlings were transplanted to plug trays with 128, 72 and 50 cells respectively, and the survival rate was 100%. The culture media made of peat, humus, tree bark powder and manure could improve the quality of the MPT seedlings. Plantation using MPT seedlings had a higher survival rate than that using bare -root seedlings by 23. 2%.
