摘要
主要报道应用舒根型容器与半轻型基质 ,培育马尾松优质容器苗 3年的研究结果。①舒根型容器培育苗木 ,根系顺导向槽往下伸展 ,不会形成卷曲根 ,并可通过空气自然截根 ,促进产生大量侧、须根 ,同时根系与基质紧密结合形成牢固的根团 ,有利于提高造林成活率 ;②两种舒根型容器相比较 ,以盒式容器为优 ,苗高生长与苗株生物量要比管形容器分别大 12 .8%与 2 4.6 % ,茎根比小 ,根系发达 ,苗木质量高 ;③在基质比较试验中 ,按苗木生长、根系数量、理化性能与保水供肥性能 4项综合权衡 ,1994年以I号基质最好 ,其次是Ⅲ号、Ⅳ号基质 ,1995年与 1996年以Ⅰ号基质为优。这几种优良基质是以树皮粉 ,锯木屑与猪栏粪等配制而成。 3年的试验结果表明 ,半轻型基质以 1/ 3树皮粉、1/ 3有机质 (锯木屑、猪栏粪等 )、1/ 3营养土 (林地表土 )
This paper mainly reported the results of three years of breeding fine seedlings of Pinus massoniana with root-thinning container and semi-light stroma.(1)In breeding the seedlings with root-thinning container,its root system could stretch down the directional grooves,not forming curled roots.Root cutting by air could promote occurrence of plenty of lateral roots and hair roots.Root system and stroma could trghtly connected to form firm root ball,which helps to increase survival rate of afforestation.(2)Box container is better than tube container. Growth and biomass of the seedling bred with box container are 12.8%,and 24.6% higher than those of seedlings bred with tube container.(3)By comparision of 4 indexes of growth of seedling,qualitithy of root,physical and chemical property,capability of keeping water and fertilizer,in 1994,No.1 of stroma was best;in 1995 and 1996,No.1 of stroma was best,No.2 and No.4 were next.The several types of fine stroma were compounded with bark powder,saw-dust and pigsty manure.Three years of test showed that,the best stroma is the stroma compounded with bark powder,saw-dust and pigsty manure at a propertion of 1∶1∶1.
