垃圾多次施用对石灰性土壤肥力的影响

Effect of Garbage Applied Many Times on Calcareous Soil Fertility

通过采用盆栽试验,探讨垃圾对石灰性褐土和褐土性土的土壤肥力的影响。试验结果表明:石灰性褐土要比褐土性土具有更强的提升土壤速效钾、速效磷、碱解氮的能力。石灰性褐土与褐土性土的最大速效钾、速效磷、碱解氮含量之差分别为17.3284mg/kg、2.3108 mg/kg和30.94mg/kg。

The test of fertilizer effect was carried out in different soils and in different application methods to investigate the effect of many applications of garbage on limp soil fertility.The results showed that the calcareous soil had the higher available N,available P and available K than the common soil.The available K,available P and available N of the calcareous soil were 17.3284 mg/kg,2.3108 mg/kg and 30.94mg/kg,respectively,which were all higher than the common soil.
