Demonstrate Research On The Integrated Utilization Technique Of Biogas Fermentative Liquid

In recent years, along with the national and local governments attach highly importance to the issue of "Agriculture, Countryside and Peasant" and constract socialism new countryside, rural household's biogas digestions have been rapid generalized and permeated. Beside got the clean quality energy, how to reflect the linking role of biogas fermentative residue (BFR) in agricultural production and exert the overall efficiency of biogas digestions is the sustainable development of biogas technology in rural areas must faces. Considerable practical experiences and pilot studies indicate that biogas fermentative residue have some special characteristics, such as fertilizer, seed soaking and feed additivity. Basis on the depth understanding the status of integrated utilization of biogas fermentative residue, author had finished demonstrate research with biogas fermentative liquid in rape, rice, pigs, sweet corn and ponkan.Biogas fermentative liquid spray can promoted the growth of rape crops and increased the yield in 2.5%~10.8%; biogas fermentative liquid seed soaking can significantly improved the quality of rice seedlings. Feeding rural finishing pig with biogas fermentative liquid raised the feeding stuff efficiency and reduced the F/G (feeding stuff growth ratio). The physics and chemistry analysis indicate that testing pig lean meat quality had been improved. Anatomize, excrement observe, hematology parameters and elements analysis indicate that feeds with biogas fermentative liquid is harmless. Biogas fermentative liquid seed soaking enhanced sweet corn seedlings quality; spraying and fertilizing test showed that the yield of treatment 2 and treatment 3 increased 5.37% and 11.75% individual than control; biogas fermentative liquid should topdress with a certain amount of fertilizer to use. Compared with the control(treatment 1), biogas fermentative liquid improved the nutritional quality of the sweet corn, amount of solubility ash content, soluble solid content (SSC), reductive sugar and total sugar increased, while the amount of vitamin C and total acitidy decreased. The content of TS/TA and SSC/TA of treatment 4 increased 74.0% and 52.7% respectively, significantly increased and were the highest among all treatments. Biogas fermentative liquid processing seeds can increase the seed to absorb more chemical element. Ponkan (Citrus reticulate Blanco) trees sprayed and topdressed with biogas fermentative liquid indicate that biogas fermentative liquid promoting Ponkan trees growth and increased percentage of fruiting rate. Compared with control, the individual tree production of treatment 2, treatment 3 and treatment 4 increased 57.19%, 44.05% and 46.91% respectively. The treatment with biogas fermentative liquid, soluble solid content increased 8.16%~9.39%, the content of total sugar...
