摘要: 探究化肥配施不同种类有机肥对黑土肥力及春玉米产量的影响,为保护好和利用好黑土地提供理论依据。基于田间定位试验,监测了单施化肥(NPK)、化肥配施玉米秸秆(NPK+ST)、化肥配施牛粪(NPK+NF)、化肥配施鸡粪(NPK+JF)和化肥配施猪粪(NPK+ZF)5个处理实施5 a后0~20 cm,20~40 cm土层土壤有机碳、活性有机碳与速效养分含量、土壤酶活性及年际间玉米产量的变化。结果表明,与NPK处理相比,NPK+NF和NPK+ZF处理显著增加了0~20 cm土层土壤有机碳含量,增幅为11.5%,11.1%;化肥配施有机肥处理显著增加了0~20 cm土层活性有机碳含量,增幅为18.3%~39.2%;NPK+NF、NPK+JF和NPK+ZF处理显著增加了0~20 cm土层速效磷和速效钾的含量,增幅分别为1.19~3.02倍,14.0%~19.6%。NPK+ST、NPK+NF和NPK+ZF处理显著增加了0~20 cm,20~40 cm土层土壤纤维素酶活性,增幅分别为15.7%~29.3%,19.4%~41.7%;NPK+JF和NPK+ZF显著增加了0~20 cm土层土壤脲酶活性,增幅分别为16.0%,12.1%;化肥配施有机肥处理显著增加了0~20 cm,20~40 cm蔗糖酶活性和磷酸酶活性,蔗糖酶活性增幅为47.3%~126.0%,19.0%~31.4%,磷酸酶活性以NPK+ZF处理增加最突出。5 a间,化肥配施有机肥处理玉米平均产量较NPK处理增加4.82%~11.70%,以NPK+ZF处理增幅最高。因此,有机肥还田可有效改善黑土耕层土壤有机碳水平、养分供应能力及酶活性,随之玉米产量得以提升。

Abstract: To investigate the effects of chemical fertilizer combined with different kinds of organic amendments on soil fertility and spring maize yield in mollisol, which provides theoretical foundation for protection and utilization of mollisol.Five treatments i.e., chemical fertilizer alone(NPK), NPK plus corn stalk(NPK+ST), NPK plus cow manure(NPK+NF), NPK plus chicken manure(NPK+JF) and NPK plus pig manure(NPK+ZF) were selected from a field experiment to monitor contents of soil organic carbon, active organic carbon, available nutrients, and soil enzyme activity at 0-20 cm, 20-40 cm soil layer after five amended years, as well as the annual change in maize yield. The results showed that compared with NPK treatment, NPK+NF and NPK+ZF significantly increased soil organic carbon content at 0-20 cm soil layer by 11.5%, 11.1%, respectively, the application of NPK plus organic amendments significantly increased active organic carbon content at 0-20 cm soil layer with the range of 18.3%-39.2%.Compared with NPK treatment, soil available phosphorus and potassium contents at 0-20 cm soil layer were significantly increased in NPK+NF, NPK+JF and NPK+ZF treatments with the range of 1.19-3.02 times, 14.0%-19.6%. In relative to NPK treatment, cellulase activity at 0-20 cm, 20-40 cm soil layer were significantly increased in NPK+ST, NPK+NF and NPK+ZF treatments with the range of 15.7%-29.3% and 19.4%-41.7%, NPK+JF and NPK+ZF significantly increased the urease activity at 0-20 cm soil layer by 16.0% and 12.1%, the activity of invertase and phosphatase at 0-20 cm and 20-40 cm soil layer was significantly increased in organic amended treatments, with the range of 47.3%-126.0% and 19.0%-31.4% in invertase activity, respectively, and NPK+ZF treatment had greater phosphatase activity than others in both soil depths. During the five years, the average maize yield was increased under combined application of chemical fertilizer and organic amendments in the range of 4.82%-11.70%, as compared with NPK, and the highest average yield was found in NPK+ZF treatment. Therefore, organic amendments could effectively improve the level of soil organic carbon nutrient supply, and enzyme activity in topsoil of mollisol, and subsequently increase the maize yield.
