Abstract:
In order to increase the content of available P in refuse composts, P dissolving intensity and microbes were analyzed from 7 kinds of tested refuse composts,and the isolated and enriched P dissolving microbes were used to produce P dissolving inoculant which was applied to potted Chinese cabbage and in fields. The results indicated that P dissolving intensity of the refuse composts usually was 11700~16100 mg/kg and the composts contain 350~860 millions P dissolving microbes per gram.The microbes able to dissolve P include: Bacillus spp.,Pseudomonas spp.. Arthrobacter spp., Alcaligenes spp. and Serritia spp.They would release 28100~46600 mg/kg and 29100~36900 mg/kg of available P from Kunyang and/or Morocco rock phosphate, respectively. By using PDI in compost. the available P in composts would be increased by 23~25 mg/kg. especially when the composts were mixed with plant materials and reek phosphate. It would effectively increase the production of Chinese cabbage by 9.5% and 90.8% to apply the composts with the P dissolving inoculant to the waste land of ted soil.
