| 摘 要： | 通过对嫩江县试验田0～20 cm土壤的测定和分析,探讨了有机无机肥配施对黑土酶活性和作物产量的影响。结果表明,有机无机肥配施有利于提高土壤酶活性,不同比例的有机无机肥配施均可使黑土过氧化氢酶、脲酶、转化酶活性增加,以有机无机肥配施1 1处理最佳;有机无机肥配施能有效提高作物产量,其处理N3M3作物产量最高。

| Abstract: | The soil of experimental field 0-20 cm was collected and analyzed in Nenjiang County,the effect of inorganic fertilizer combined with organic manure on soil enzyme activity and crop yield was studied.The results showed that inorganic fertilizer combined with organic manure was helpful to improve soil enzyme activity,different proportions of inorganic fertilizer combined with organic manure all could increase soil catalase,urease,and invertase activities.The inorganic fertilizer combined with organic manure ratio 1:1 was the best treatment.The inorganic fertilizer combined with organic manure could effectively enhance the crop yield,and N3M3 treatment had the highest crop yield. |
