Abstract:

In order to increase the yield of bamboo shoots and control soil obstacle factors happening in the bamboo forest (Phyllostachys praecox f. prevelnalis), the comparative experiment of soil decontaminant Ronbao had been conducted for consecutive 3 years. The results of experiment showed that: the yield of bamboo shoots at the application rate of 600 kg/hm2 plus 45% compound fertilizer at 900 kg/hm2 increased averagely by 30.1% in comparison with that under CK without the application of soil decontaminant. After the application of soil decontaminant, soil pH values were significantly higher their controls (P<0.05) while the contents of soil exchange acidity were significantly lower than their controls (P<0.05). No bacteria strains were observed in the decontaminant-treated soil whereas 18 soil bacteria strains were found in the control. This showed that the soil decontaminant had a sterilization effect, resulting in mitigating the soil-borne disease and increasing the survival rate of bamboos.
