Fertilizers with a single conventional control design 3 to deal with 5 replicates. The results showed that the yield of single plant treated with biogas slurry as basal fertilizer and biogas slurry was increased by 6.99kg compared with the conventional single application of chemical fertilizers for two years. In 1997, the yield per plant (25 plants) was 8.70% higher than that of the control. In 1998 Increase by 12.07%, the difference reached a very significant level; in 1997, the biogas processing was 2.90% more than the pig manure processing and 3.19% in 1998, with no significant difference; in 1997, pig manure processing increased by 6 .4 7% in 1998, an increase of 8.6%, the difference was significant. At the same time, it also shows that the application of biogas fertilizer can also improve the quality of Guanxi honey pomelo with obvious economic benefits. An average increase of 14 6 6 3.4 Yuan hm2 over the two years of comparison.
