摘要

通过大田试验

研究了N

100

(尿素提供100%的氮)、M

(味精废液和尿素分别提供10%和90%的氮)、M

(味精废液和尿素分别提供30%和70%的氮)和M

(味精废液和尿素各提供50%的氮)等处理对西瓜根际土壤微生物量碳(MBC)和微生物量氮(MBN)含量的影响。结果表明

施用味精废液使土壤生物过程活跃

有利于土壤有机物质的转化和西瓜正常生长所需的营养供应。在西瓜不同生育期

根际土壤MBC和MBN含量动态变化规律不同。与M

处理相比

和M

处理对西瓜根际土壤微生物量碳、氮的影响较小。分析可知

味精废液与化肥以3:7比例配施对西瓜根际土壤微生态环境的作用效果最佳

更有利于平衡西瓜氮素营养。

Abstract

A field experiment including five treatments

they were CK(neither urea nor chicken manure was applied)

N100(100% of nitrogen was provided by urea)

M10N90(10% and 90% of nitrogen was provided by monosodium glutamate wastewater and urea

respectively)

M30N70(30% and 70% of nitrogen was provided by monosodium glutamate wastewater and urea

respectively)

and M50N50(50% and 50% of nitrogen was provided by monosodium glutamate wastewater and urea

respectively) was performed. The experiment was to evaluate the effect of monosodium glutamate wastewater co-applied with inorganic fertilizer on soil microbial biomass carbon(MBC) and microbial biomass nitrogen(MBN) contents in the rhizosphere soil of watermelon. The results showed that using monosodium glutamate wastewater can accelerate soil biological processes

and was of great advantage to the transformation of organic matter and provision of nutrition to meet the needs of watermelon's regular growth. The dynamic changes of MBC and MBN contents were different at different growth duration. Compared to the M30N70 treatment

the M10N90 and M50N50 treatments had less effect on MBC and MBN contents in the watermelon rhizosphere soil. In conclusion

monosodium glutamate wastewater co-applied with inorganic fertilizer

especially the M30N70 treatment

could improve the ecological environment of watermelon rhizosphere soil and could balance nitrogen alimentation.
