摘要:
为改善土壤质量，优化土壤微生物区系，采用田间小区试验与室内化验分析相结合的方法，研究了优化施肥结合施用腐殖酸钾及沸石对设施土壤微生物生物量碳氮的影响。结果表明：番茄生育期间，土壤微生物生物量碳和微生物生物量氮总体呈现出先增加后降低的变化趋势，微生物生物量碳出现的高峰期要早于微生物生物量氮。与不施化肥、农民习惯施肥相比，优化施肥的基础上添加腐殖酸钾、沸石能不同程度地提高土壤微生物生物量碳氮含量。优化施肥+沸石处理的土壤微生物生物量碳氮占土壤有机碳、全氮的比例最高，分别比不施化肥高41.2%和61.9%，比农民习惯施肥高9.1%和21.4%；其次是优化施肥+腐殖酸钾+沸石处理，分别比不施化肥高41.2%和38.1%，比农民习惯施肥高9.1%和3.6%。可见，优化施肥的基础上添加腐殖酸钾或沸石在一定程度上可以改善设施土壤质量。
Abstract:
In order to improve soil quality and optimize soil microflora,the effects of optimized fertilization on microbial biomass carbon，nitrogen contents of greenhouse soil were studied by methods of field plot experiments and indoor test analysis.The results showed that the contents of soil microbial biomass carbon(MB-C)and soil microbial biomass nitrogen(MB-N)were firstly increased and then decreased.The peak value of MB-C appeared earlier than that of MB-N.Compared with no nitrogen treatment and farmer practice fertilization treatment,MB-C and MB-N could be increased by the treatments of optimized fertilization plus potassium humate or optimized fertilization plus zeolite.For the treatment of optimized fertilization plus zeolite,rates of MB-C and MB-N in organic carbon and total nitrogen were the highest and higher than no nitrogen treatment 41.2% and 61.9% respectively,higher than farmer practice fertilization treatment 9.1% and 21.4% respectively.The rate was higher in the treatment of optimized fertilization plus potassium humate and zeolite,higher than no nitrogen treatment 41.2% and 38.1% respectively,higher than farmer practice fertilization treatment 9.1% and 3.6% respectively.According to this study,we concluded that greenhouse soil quality could be improved by optimized fertilization plus potassium humate or zeolite.
