摘  要：
[目的]探讨微生物肥料对谷田土壤环境及谷子产量的影响。[方法]设6个处理,分别为CF(N 187.5 kg/hm~2、P_2O_5105 kg/hm~2、K_2O 45 kg/hm~2);CY(常规有机肥2 250 kg/hm~2);CK(不施肥);WF(N 187.5 kg/hm~2、P_2O_5105 kg/hm~2、K2O 45 kg/hm~2+微生物肥75 kg/hm~2);WY(有机肥2 250 kg/hm~2+微生物肥75 kg/hm~2);WB(不施肥+微生物肥75 kg/hm~2)。通过研究土壤温度、近地层CO_2浓度、土壤紧实度、谷子农艺性状等,探讨微生物肥料的施用效果。[结果]添加微生物菌肥后的WY、WF、WB 3个处理较未添加的处理,0~20 cm土层平均地温增加了0.10~0.23℃,0~10 cm土层平均地温增加了0.14~0.27℃;近地层CO_2浓度增加了10~22 mg/L,增幅3.8%~7.6%;0~6 cm土层土壤紧实度降低了2.6%~7.9%,6~12 cm土层降低了2.0%~5.8%;产量增加了125~600 kg/hm~2,增幅3.1%~14.4%。[结论]该研究为谷子合理施肥、提高肥料利用效率提供科学依据。

摘  要：
[Objective]To study the effect of microbial feitilizer on soil environment and grain yield in millet field.[Method]Six treatments were set up in this study,namely CF( N 187.5 kg/hm~2,P_2O_5105 kg/hm~2,K_2O 45 kg/hm~2),CY( 2 250 kg/hm~2),CK( no fertilization),WF( N187.5 kg/hm~2,P_2O_5105 kg/hm~2,K2 O 45 kg/hm~2 plus 75 kg/hm~2 microbial fertilizer),WY( organic fertilizer 2 250 kg/hm~2 plus microbial fertilizer 75 kg/hm~2),WB( no fertilization plus microbial fertilizer 75 kg/hm~2). The effects of microbial fertilizer were investigated by studying the soil temperature,the concentration of CO_2 near the formation,the compactness of soil and the agronomic characters of grains.[Result]After adding inorganic fertilizer,three processing including WY,WF,WB,the following indicators have changed significantly than no added processing. 0 to 20 cm mean ground temperature increased by 0.10 ℃ to 0.23 ℃,0 to 10 cm mean ground temperature increased by 0.14 ℃ to 0.27 ℃,the concentration of CO_2 in the near strata increased by 10 mg/L to 22 mg/L,increasing by 3.8% to 7.6%. The compactness of 0-6 cm soil decreased by 2.6% to 7.9%,and that of 6 to 12 cm decreased by 2.0% to 5.8%. The output increased by 125 kg/hm~2 to 600 kg/hm~2,increasing by 3.1% to 14.4%.[Conclusion]This study provides a scientific basis for the reasonable fertilization of millet and the improvement of fertilizer utilization efficiency.
