Abstract:
The organic matter and available N，P，K content were determined by different stubble way of seabuckthorn forest soil soil samples.The results showed that arsenic sandstone area of different stubble way of seabuckthorn forests soil the soil organic matter content in addition to stubble 75% showed a decreasing trend，30%,50%,100%soil organic matter content of soil enrichment to the middle layer (11~20 cm),30%middle soil organic matter content was the highest，16.5 g/kg，100% middle soil organic matter content was minimal，6.28 g/kg.Soil available N，P，K content in 50% was the highest，which readily available P，K enrichment in middle earth (11~20 cm).Stubble 75% of the soil，the soil N，P，K contents were higher than middle soil and subsoil；30% for each layer，in addition to the content of soil organic matter and soil was higher than that of 50%，N，P，K contents were less than 50%.This research may provide different stubble on Hippophae rhamnoides forest soil chemical properties and provide theoretical basis for the effect of it.
