Study of effect on soil salinity and respiration intensity by the straw compost

摘要

After the straw fermentation and add in soil for pot experiment, analysis of the soil pH, salinity, respiration intensity, and the relationship between soil pH and respiration intensity, salinity and respiration intensity before and after pot, concluded: pot under experimental conditions help to reduce soil pH and salinity, increase soil respiration intensity, soil pH, salinity and soil respiration intensity trends reverse. Experimental results show that the conditions for the experimental group 19-27 are more conducive to low soil pH and salinity, increase soil respiration intensity, and to improve soil properties, making it suitable for crop growth.
