Effects of the maize root on soil microbial flora under different cultivation patterns;

Research on factors hindering continuous cropping of flue-cured tobacco in soil ecosystem was reviewed with regards to autotoxicity of flue-cured tobacco roots exudates,deterioration of soil chemical characteristics,change of soil microbial flora,and decline of soil enzyme activities.

In order to improve the bearing capacity of foundations,some new grouting methods and techniques have been employed in the consolidation grouting of backfilled sand-cobble stratum,including casing drilling,filling sand in a perforated pipe,protecting the wall with SM plant glue,forming a hole by diamond drilling and grouting in stages.
