Fig 4. Diversity analysis of bacteria in response to the following treatments.

Fig 4

DP267 = Trichoderma spp. strain 267 added to soil after fumigation. DPHZ = Commercial T. harzianum added to soil after fumigation. DP = Fumigation without the addition of Trichoderma. CK = Untreated control. Soil was sampled from each treatment 2–20 cm deep on day 1 before applying Trichoderma (a), on day 7 after the third applying Trichoderma (b) and when the cucumber plants were uprooted(c). The number of asterisks indicates the degree of correlation (P < 0.05): (*p < 0.05, **p < 0.01, ***p < 0.001).
