Effect On Different Treatments On The Natural Heap Storage Beef Cattle Manure Composting And Nutrient Loss Law

With the continuous improvement of scale and intensification of China’s beef production, the emissions were also followedly increasing, due to lack of safe handling measures of beefcattle manure, a great quantity of beefcattle manure was stacked but not effectively used, which resulting in the loss of nutrients in the cattle manure but also seriously polluted to the environment, so it became a major environmental problem for beef cattle production in China. This study closely combined the beef actual production in Jilin Province, by different treatment of beefcattle manure, separately using open-air natural heap storage, shed naturally heap storage, the heap storage of shed plusing cellulose decomposing bacteria to study beefcattle manure under the conditions of the naturally heap storage and adding efficient cellulose decomposing bacteria, the situation of each group of beefcattle manure, of which the dynamic changes of nutrients and degradation and maturity. So as to identify effective beefcattle manure treatment, and provide a theoretical reference and technical support for rational and efficient use of beefcattle manure.In this experiment, cattle in Jilin Province were chosen as the object of study, set three treatment groups, of which three replicates for each treatment group, respectively sampled on0,5,15,25,35,45,55,65d, Determination nutrient content of sampled beefcattle manure and the decomposition of beefcattle manure in fermentation heap storage process. The results show that on the third day the temperature reached52℃after vaccination cellulolytic bacteria, and reached the highest value at61℃on7d after a heap storage; temperature of shed group pile reached above50℃4d later than the inoculated group, inoculated group above50℃continued for10d, which reach the standards of animal manure harmless, studio group was6d, which was4d less than the inoculated group; moisture, organic matter content of inoculated group heap decreased fastest; after inoculation of cellulolytic bacteria, there was a strong role in the degradation of cellulose and hemicellulose, while lignin degradation capacity was weak, at the end of heap storage, fiber relative degradation rates of each group were as follows:57.45%,46.01%,43.18%; The decomposition rate of hemicellulose were as follows:60.43%,49.16%,46.01%, the degradation rate of lignin was not significantly different between groups. Total nitrogen and nitrogen of alkaline hydrolysis both showed a first decreased and then an upward trend, while the ammonium nitrogen showed the opposite trend, nitrate nitrogen concentration variation showed a pre-emergence slightly declined and then gradually increased and finally decreased gradually process. nitrogen in of bacteria in pile of beefcattle manure was higher than the other groups, indicating that vaccination cellulolytic bacteria contending nitrogen better, total phosphorus content of beefcattle manure in each group showed a rising trend, in which available phosphorus content showed a first decreased and then gradually upward trend; total K, available K both shown a growing trend in the whole heap storage period. The decomposition of beefcattle manure, the matrix within heap of the inoculated group on35d changed into a brown reproductive quality, suggesting that the beefcattle manure pile was basically coming into the maturity stage. C/N ratio among the groups showed a declining trend, of which the inoculated group declined fastest, when on35d it reduced below20, while the open group in the entire heap storage period had not dropped below20. This indicated that adding cellulolytic bacteria could make the pile ahead of maturity. total humic acid of beefcattle manure of heap storage between processing groups showed a declining trend, and humic acid content showed a firstly decreased and then increased trend, while fulvic acid showed a reducing trend. At the end of the heap storage, the total content of humic acid of each treatment group were:72.23g/kg,73.36g/kg,89.27g/kg, humic acid contents were:43.29g/kg,41.47g/kg,43.04g/kg, and fulvic acid contents were:28.94g/kg,31.89g/kg,46.23g/kg, Seed germination index of inoculated group was significantly higher than the other two groups, furtherly showed that the vaccination cellulolytic bacteria could promote the decomposition of the pile, and shorting the pile composting time.
