摘　　要：分析在前茬水稻秸秆全量还田下,种植小麦应用“生物腐熟菌+普通尿素+控释尿素”简化施肥(一基一追)技术模式对生育期、产量及效益的影响,探讨在“一基一追”的栽培条件下的普通尿素与控释尿素的最佳比例。结果表明,在本试验条件下,普通尿素与控释尿素比例在7∶3的情况下,产量最高达到589.11 kg/0.067 hm^(2),比不施肥处理多389.8 kg/0.067 hm^(2),比不施用缓释肥处理多4.87 kg/0.067 hm^(2)。实现了施肥次数减少、基础产量提高和化肥减量增效,促进了耕地质量提升。This paper analyzed the effect of the simplified fertilization(one base and one topdressing)technology mode of"biological maturity bacteria+common urea+controlled-release urea"on the growth period,yield and benefit of wheat planting under the condition of full return of the previous crop of rice straw,and discussed the optimal ratio of common urea and controlled-release urea under the cultivation condition of"one base and one topdressing".The results showed that under the conditions of this experiment,when the ratio of common urea to controlled release urea was 7:3,the maximum yield reached 589.11 kg/0.067 hm^(2),389.8 kg more than the treatment without fertilization,and 4.87 kg more than the treatment without slow-release fertilizer.It has reduced the number of fertilizer application,improved the basic yield and increased the efficiency of fertilizer reduction,and promoted the quality of cultivated land.
