| 为了解决长期施用化肥导致土壤质量下降，甜菜产量低，品质差的问题，在甘肃省张掖市甘州区明永镇甜菜种植基地，采用田间试验方法，连续3 a进行了不同比例羊粪与化肥配施对土壤质量及甜菜含糖率和效益影响的研究。结果表明：施用100%羊粪比其他处理有利于改善土壤质量，提高甜菜含糖率，与100%化肥比较，土壤容重、pH值和全盐降低10.45%、15.14%和15.35%，孔隙度和团聚体增加5.29和5.81个百分点， 总持水量、CEC、有机质、有机碳和有机碳密度增加10.69%、16.85%、29.90%、29.93%和16.33%，蔗糖酶、脲酶、磷酸酶和多酚氧化酶活性增加18.93%、27.27%、21.74%和17.95%，甜菜含糖率增加2.74个百分点；施用100%化肥比其他处理有利于提高土壤全盐和氮磷钾含量，与100%羊粪比较，全盐含量提高18.14%，碱解氮、速效磷和速效钾含量提高1.23、1.78倍和1.22倍；施用50%羊粪+50%化肥比其他处理更有利于提高甜菜产量和经济效益，与100%化肥比较，甜菜叶丛高度、根体长度、根直径、单株根重、根产量、施肥利润和肥料投资效率增加6.40%、8.75%、19.00%、6.96%、5.33%、0.10万元·hm-2和0.02元·元-1。 |

| In order to solve the problems of soil environmental quality degradation, low yield and poor quality caused by long\|term application of chemical fertilizers, a field experiment was carried out in Ganzhou District, Zhangye City, Gansu Province to study the effects of different proportion of sheep manure and chemical fertilizer on soil environmental quality and sugar content and benefit of sugar beet for 3 consecutive years. The results showed that the application of 100% sheep manure was beneficial to the improvement of soil environmental quality and sugar content of sugar beet in comparison to other treatments. The soil bulk density, pH value and total salt were reduced by 10.45%, 15.14% and 15.35%, compared with that of 100% fertilizer treatment. At the same time, porosity and aggregates increased by 5.29 and 5.81 percentage points, and the total water capacity, CEC, organic matter, organic carbon and organic carbon density increased by 10.69%, 16.85%, 29.90%, 29.93% and 16.33% respectively. The activity of sucrase, urease, phosphatase and polyphenol oxidase increased by 18.93%, 27.27%, 21.74% and 17.95%. Sugar content of beet increased by 2.74%. Compared with other treatments, application of 100% fertilizer was beneficial to increasing of the contents of total salt, nitrogen, phosphorus and potassium in the soil, when compared with that of 100% sheep manure treatment, the total salt content increased by 18.14%, and the alkali\|hydrolyzed nitrogen, available phosphorus and available potassium increased by 1.23, 1.78 and 1.22 times. Based on the economics theory analysis, the 50% sheep manure + 50% chemical fertilizer treatment showed better results than other treatments in improving sugar beet yield and economic benefits. Compared with 100% chemical fertilizer, the 50% and 50% treatment's sugar beet cluster height, root length, root diameter, root weight, root yield per plant, fertilizer profit and fertilizer efficiency of investment increased by 6.40%, 8.75%, 19.00%, 6.96%, 5.33%, 0.10 yuan·hm-2 and 0.02 yuan·yuan-1, respectively. |
