摘　　要：[目的]探索谷氨酸发酵废液农业利用问题。[方法]采用盆栽试验,研究了谷氨酸发酵废液处理对水稻产量构成因素与养分吸收和分配的影响。[结果]与常规单施无机肥F处理相比,等氮量全部施用谷氨酸发酵废液处理M,可增加分蘖数,但穗粒数少,每株中养分积累量氮素、钾素较低,磷素积累量较高。减氮量配施谷氨酸发酵废液FM_2处理,可提高穗粒数,但分蘖数较少,某些器官中氮磷含量并未随氮肥用量的减少而降低。等氮量配施谷氨酸发酵废液FM_1处理,提高分蘖数和穗粒数,对提高水稻产量效果显著,各器官氮磷含量和积累量均高于F处理。[结论]谷氨酸发酵废液处理可提高水稻产量,促进养分向各器官转移,尤其是向籽粒转移,以等氮量配施谷氨酸发酵废液FM_1处理效果最显著,但需提高钾肥用量。[Objective]To explore the agricultural utilization problems of glutamate fermentative waste.[Method]Effect of glutamate fermentative waste on rice yield components and nutrient absorption and distribution were studied by pot experiment.[Result]Compared with inorganic fertilizer F,the treatment of M which used glutamate fermentative waste only,could increase the tiller number,decrease kernels number,and N and K accumulation in each plant in M treatment was low,but P accumulation was high.The treatment of FM2 which was decreased-nitrogen and combining application of glutamate fermentative waste,could increase kernels number and decrease the tiller number,the accumulation of N and P in each plant in FM2 didn＇t decrease because of decreased-nitrogen.The treatment of FM1 which was equal-nitrogen and combining application of glutamate fermentative waste,could increase both kernels number and the tiller number,could boost significantly the rice yield,N and P content and the accumulation of N and P in each plant also increased in FM1.[Conclusion]The application of glutamate fermentative waste can increase the rice yields,promote the nutrient transportation,especially the transportation to the grain.The treatment of FM1 which is equal-nitrogen and combining application of glutamate fermentative waste is the best.But the treatment of glutamate fermentative waste requires more potash fertilizer.
