不同育苗基质对火焰树小苗生长量的影响试验研究

An Experimental Study of the Effect of Different Substrata on the Growth of Seedlings of the Flame Tree

开展5种不同育苗基质对火焰树小苗生长量、生物量和根冠比的影响,结果表明:5种不同基质对火焰树小苗的苗高、地径、主根长、地上部分鲜质量和地下部分鲜质量各处理间均具有极显著影响(P<0.001)。苗高、地径、主根长、地下部分鲜质量和地上部分鲜质量生长表现较好的基质配方均是3/5遮渣+/5针叶剧末+1/5牛粪的混合基质,其它配方的育苗基质对苗高、地径、主根长、地下部分鲜质量和地上部分鲜质的响应不一致。

In this paper, researches were conducted on five different nursery substrata of Spathodea cam- panulata seedlings growth, biomass and root shoot ratio. The results showed that 5 kinds of different sub- strata had significant effects （ P 〈 0. O1 ） on the seedling height, diameter, root length, fresh quality and underground parts of the fresh weight of Spathodea campanulata for each treatment. As for seedling height, diameter, root length, underground fresh quality and fresh weight of growth performance, a better matrix formulation was the mixed matrix of 3/5 bagasse, 1/5 needles and 1/5 cow dung. And the effects of other recipes of nursery substrate on seedling height, ground diameter, root length, underground fresh qual- ity and response of the fresh matter were not consistent.
