Variation of Soil Enzyme Activity and Soil Nutrients in Aerially Seeded Pinus massoniana Plantation Replanting with Schima superba
We took the aerially seeded Pinus massoniana plantation and mixed forest of Pinus massoniana and Schima superb to study the variation and relation between soil nutrients and the activity of urease, invertase and acid phosphatase.The in-vertase, total nitrogen and available potassium of the two forest types at the same soil layer showed significant differences ( p<0.05) , the differences of urease of two forest types were significantly at 0-10 cm soil layer ( p<0.05) , while the differ-ences of acid phosphatase were significantly at >10-20 cm and >20-40 cm soil layers (p<0.05), and total P, organic mass fraction at 0-10 cm,>10-20 cm soil layers ( p<0.05) .The soil urease, invertase, acid phosphatase and soil nutri-ents of two forest types were significantly decreased with the increase of soil depth.The soil urease, invertase and total ni-trogen, total P, available N, available K and organic matter had a extremely significant positive correlation (p<0.01), a positive correlation with total potassium ( p<0.05) , acid phosphatase and total P , available P and organic matter had a ex-tremely significant positive correlation (p<0.01), and was positively correlated with available N (p<0.05).The aerially seeded Pinus massoniana plantation with Schima superb as complimentary planting can help to enhance soil nutrients, and activity in urease and invertase.
