摘要
针对广西土壤养分状况，利用木薯皮、淀粉渣、酒精渣，经生物发酵处理，配以合理氮、磷、钾化肥研制成生物有机复混肥。2006～2007年在木薯、甘蔗上进行施用试验。结果表明：在同等N＋P2O5＋K2O总养分施用条件下，生物有机复混肥与进口复合肥、通用复混肥比较，木薯分别增产14．16％、16．94％，甘蔗分别增产4．46％、12．40％。土壤有机质、速效氮、速效磷等养分有显著的提高。
According to the content of soil nutrient condition in Guangxi, the skin of cassava, filter mud and vinasse from starch processing factory and distillery were mixed and fermented,and chemical N, P and K were added after fermentation to produce bio-organic compound fertilizer. During 2006-2007, the bio-organic compound was applied in the cassava and sugarcane field. The results showed that at the same level of total nutrient contents of N, P205, K20, the yield of cas- sava and sugarcane applied compound fertilizer increased by 14.16% and 4.46% than that of the imported compound fertilizer treatment, respectively, and increased by 16.94% and 12.40% than that of the common compound fertilizer. The application of bio-organic fertilizer could increase the contents of soil organic matter, available N and available P.
