Equations

O

SE = 9.43 × 10–6 + 1.80 × 10-6S + 2.84 × 10-5I, R2 = 0.9472

B

SE = − 2.34 × 10–5 + 2.45 × 10-6S + 2.93 × 10-5I, R2 = 0.9800

A

SE = − 9.85 × 10–5 + 5.06 × 10–5 ln(S) + 6.39 × 10–5 ln(I), R2 = 0.9942

  1. The significance level of the equation is 0.05. O is bare slope, B is Prunella vulgaris combined with earthworm planting slope,A is Single planting prunella vulgaris slope.
