不同处理对树木落叶生物基质理化性质的影响

对经不同处理获得的悬铃木、加杨的树木落叶生物基质的理化性质进行了试验研究。结果表明:处理7有利于固着植物,处理4有利于根系的通气,处理1可提供较多的可利用水,处理2的水气比适中,可能适合于多种植物。各种处理的pH都呈微酸性,差别不是很显著,相比之下,处理7、6、3更有利于P素的转化,处理7的基质溶液中离子浓度较高,在使用时有必要进行洗盐处理。从养分含量来看,悬铃木落叶基质和加杨落叶基质都有较为丰富的营养,其中处理7可提供较高的可利用N、P、K的营养,其次是处理3和处理6。

Effects of Different Treatment on the Physical and Chemical Properties of Tree Leaves Biological Matrix

The different treatments to get the Platanus orientalis L and the Populus canadensis Moench leaves physical and chemical properties of biological matrix was studied.The results showed that treatment 7to deal with a solid plants,for the root system treatment 4ventilation,treatment 1could provide more available water,treatment 2moderate in water and gas ratio,could be suitable for various plants.Various processing pH value was acidic,the difference was not very significant,in contrast,processing 7,6,3more conducive to P element transformation,in dealing with treatment 7of matrix solution,the concentration of the ions was higher,in use was necessary to deal with semidiameter.From the nutrient content to see,leaves bio-medium of Platanus orientalis L and the Populus canadensis Moench had achieved matrix rich nutrition,among them,the processing and could provide higher available N,P,K nutrition,followed by processing 3and 6processing.
