2O3.43 percent) of organic fertilizer. The germination rate of the seeds is 80 percent and the germination index of the seeds is 98 percent by using Chinese cabbage seeds. In the composting process, the compost is long in decomposing time due to the fact that the compound microbial inoculum is not added to the materials, the measured parameters such as the seed germination rate and the seed germination index are obviously lower than those of the fertilizer added with the compound microbial inoculum, and meanwhile, a large amount of organic matters and nitrogen are lost, so that the organic fertilizer with higher quality is not obtained easily.
In conclusion, the organic fertilizer composted by using the fish manure of the captive breeding system provided by the invention has the advantages that the components are reasonably compatible, the fertilizer quality is improved under the synergistic effect, the fertility of the prepared organic fertilizer is good, and the germination rate and the seed germination index of crops are greatly improved.
The invention is not to be considered as limited to the particular embodiments shown, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
