Phosphorus Status and Inorganic Phosphorus Fractions in Apple Orchards Soil with Different Planting Years
In order to provide scientific basis for phosphorus fertilizer application in apple orchard in Jiaodong region
total phosphorus
available phosphorus
inorganic phosphorus and inorganic phosphorus fractions in 0-100 cm layer soil of apple orchards with different planting years were analyzed. The average contents of total phosphorus
inorganic phosphorus
and available phosphorus in the 0-40 cm soil layer were 0.76 g/kg
681.10 mg/kg
73.05 mg/kg respectively. The planting years had a significant effect on the soil phosphorus contents. The total soil phosphorus
available phosphorus and inorganic phosphorus fractions decreased with the deepening of soil layer. The inorganic phosphorus mainly existed in the form of Al-P and O-P
followed by Fe-P and Ca-P. The planting years significantly affected the composition of inorganic phosphorus fractions
and the proportion of Al-P was the highest in 11~15 years apple orchards
while the proportion of O-P was the highest in 16~20 years apple orchards. The results of correlation analysis and path analysis showed that Al-P was a relatively effective source of phosphorus in this region.
