摘　　要：通过田间试验的方法,研究秸秆还田与锌肥配施对土壤养分、春玉米产量及子粒锌含量的影响,为合理施用锌肥提供理论依据。研究表明,无秸秆还田时,施用锌肥后比不施锌土壤有效锌含量提高64.00%,全锌含量提高2.51%,在施锌情况下,S1Z4处理比S0Z4土壤有效锌含量增加了0.21 mg/kg;秸秆还田可以增加土壤速效氮磷钾含量,而单独施锌对土壤速效氮磷钾含量无显著影响;无秸秆还田条件下,施锌肥可增加春玉米产量14.06%,秸秆还田条件下,施锌则可增产17.3%;无秸秆还田情况下,施用锌肥使春玉米子粒锌含量提高20.17%,秸秆还田配施锌肥则使子粒锌含量提高32.61%。秸秆还田与锌肥配施是提高土壤供锌能力、增加春玉米产量和子粒锌含量的有效方法。Field experiments were conducted to study the effects of straw returning combined with zinc fertilizer on soil nutrients,spring maize yield and grain zinc content to order to provide theoreti⁃cal basis for rational application of zinc fertilizer.The results showed that available zinc content of soil increased by 64.00%and total zinc content increased by 2.51%by applying zinc fertilizer,and under zinc application,the available zinc content of soil in S1Z4 treatment increased by 0.21 mg/kg compared to S0Z4 treatment;Straw returning could increase the content of soil available nitrogen,phosphorus and potassium,but zinc application alone had no significant effect on the content of soil available nitrogen,phosphorus and potassium;Under the condition of no straw returning to the field,the yield of spring maize could be increased by 14.06%by applying zinc fertilizer,and under the con⁃dition of straw returning to the field,the yield of spring maize could be increased by 17.3%by apply⁃ing zinc fertilizer;The application of zinc fertilizer increased zinc content of spring maize grain by 20.17%,while straw returning combined with zinc fertilizer increased zinc content of grain by 32.61%.In conclusion,straw returning combined with zinc fertilizer is an effective way to improve soil zinc supply capacity,and increase spring maize yield and grain zinc content.
