| 摘 要： | 以生姜为试材，分析了不同种类肥料配施对生姜根系及根际土壤酶活性和微生物数量的影响。结果表明：生物有机肥配施处理的生姜根鲜质量增加，根系活力增强，分别比普通化肥处理和普通有机肥处理的根鲜质量增加28.3%、16.4%，根系活力提高41.2%、20.6%|生物有机肥处理的土壤有机质含量有所提高，在生姜生长旺盛期达到最大值，分别比普通化肥处理和普通有机肥处理增加45.4%、11.1%|生物有机肥配施可提高土壤微生物数量，与普通化肥处理相比土壤细菌增加了449.1%，真菌增加了374.3%，放线菌增加了489.8%，总量增加了451.5%，增幅高于普通有机肥处理|生物有机肥配施可提高土壤蔗糖酶、脲酶、过氧化氢酶活性，促进了土壤有机质的分解转化。

| Abstract: | Taking ginger(Zingiber officinale Rosc.)as experiment material,this paper analyzed the effects of different fertilizers combined application on ginger root system and rhizosphere soil enzyme activities and micro-organism quantity.The results show that the biological organic fertilizer can improve the fresh weight of ginger root and strengthen the root activity.The fresh weight of ginger root was higher than that applying common chemical fertilizer or common organic fertilizer by 28.3% and 16.4%,and the root activities were increased by 41.2% and 20.6%.The biological organic fertilizer can increase the soil organic matter.The max value of soil organic matter is achieved during vigorous stage. The contents were higher than that applying common chemical fertilizer and common organic fertilizer by 45.4% and 11.1%,respectively.This fertilizer could significantly improve soil microbe quantity.Compared with that applying common chemical fertilizer,the population of bacteria increased by 449.1%,that of fungi increased by 374.3%,that of actinomycetes increased by 489.8%,and the total population of these 3 kinds of microorganism was increased by 451.5%.Its increased quantity was higher than that applying common organic fertilizer.The activities of invertase,urease and catalase in soil were increased obviously by applying biological organic fertilizer.Thus the decomposition and transformation of soil organic matter was promoted. |
