摘要：选用香樟、乳源木莲和马褂木3种乡土阔叶树种,开展基质配比和容器规格对苗木出圃质量影响的研究。结果表明:不同树种容器苗对基质类型和配比的生长反应差异很大,树种与基质间的互作效应显著。以泥炭土为主的配比基质容器苗生长较快,而以沤制后锯屑为主的配比基质容器苗生长较慢。纯泥炭土基质虽具有很多优点,但因其价格高,浇水后饱和持水量过大而影响苗木根系生长,不提倡在生产上广泛应用。本试验优先推荐泥炭土∶焦泥灰∶黄心土=39∶40∶20(体积比)的基质(另加w=1%的钙镁磷)配方。如若利用锯屑作基质,应减少锯屑的配比用量,其比例控制在20%以下。针对树种生物学特性和适用配比基质,确定相应的容器苗出圃规格,以实现江南地区梅雨季节的容器苗造林。研究认为,在生产上可考虑采用管状容器育苗,但其前提条件是确保梅雨季节能及时造林,否则应选用规格较大的杯状容器。
This paper dealt with the studies on how the media mixture and the containers size affect seedling quality of three native broad-leaved species of Cinnamomum camphora, Manglietia yuyuanensis and Liriodendron chinense. The results indicated that media type and mixture produced a great impact on the growth of container seedlings of various species. There was great interaction between species and media. The container seedlings in the media of peat as main material grew more quickly. However, the container seedlings in the media of sawdust as main material grew more slowly. The pure peat has many advantages, but it should not be used widdy in production because of higher price and unfavorable effect of saturated water content on the root growth after watering. The test showed that the best medium mixture ratio of peat, burnt-soil, yellow soil and calcium magnesium phosphate was 39 ： 40 ： 20 ： 1. If sawdust is used as medium, the sawdust mixture ratio of medium should be reduced and controlled below 20%. To counter biological characteristics of tree species and applicable medium mixture, the size of container seedhngs should be made in order to achieve afforestation in the rainy season in the south of Yangtze River area. The studies showed that the fistular container seedlings may be adopted, but the prior condition is to make sure afforestation in rainy season in time, or the bigger size of cuppy container should be used.
