Abstract
A pot experiment including four treatments,i.e.CK(neither urea nor cattle manure was applied),CF(100% of nitrogen was provided by urea),CM(100% of nitrogen was provided by cattle manure),and CM+CF(50% and 50% of nitrogen was provided by cattle manure and urea,respectively) was conducted to evaluate the effects of cattle manure co-applied with inorganic fertilizer on root morphological characteristics and microorganism population,enzyme activtiy in the rhizosphere soil of Platycladus orientalis.The results indicated that compared with CF treatment,CM+CF treatment significantly increased the root surface area,specific root surface area,total root length,root tip number and root activity,showing 110.01%,59.27% and 28.54% increases in root surface area,respectively,in comparison to the treatments of CK,CF and CM.At the same time,the microbial populaton,microbial biomass carbon(MBC) and microbial biomass nitrogen(MBN) in CM+CF treatment was also increased,demonstrating 62.22% and 45.35% increases in MBC and MBN contents compared to the CF treatment,respectively.The microbial biodiversity indices and microbial population had the same variation tendency between CM and CM+CF treatments,while the CK and CF treatments had the opposite variation tendency.In additon,the activity of urea enzyme,catalase enzyme,polyphenol oxidase enzyme and invertase enzyme in CM+CF treatment was still improved,and the increase amplitude of polyphenol oxidase enzyme was the maximum.In contrast to CM+CF treatment,the CM treatment had less effect on the rhizosphere environment of Platycladus orientalis.In conclusion,cattle manure co-applied inorganic fertilizer can be beneficial to increase the number of soil microorganism and enzyme activities,and create a good miro-ecological environment for the growth of Platycladus orientalis.
