摘要
【目的】研究有机肥替代20%化肥对土壤养分含量及春小麦产量的影响,为干旱区绿洲小麦减施化肥培肥地力提供科学依据。【方法】采用连续2年大田试验。设置不施肥处理(T1),常规施肥处理(T2)以及有机肥替代20%化肥处理(T3)3个处理。【结果】有机肥替代20%化肥处理与农户常规施肥处理均能增加小麦产量、提高土壤速效养分含量以及有机质含量,有机肥替代处理会在减少化肥施用的同时达到与农户常规施化肥一样的效果,且土壤各养分的增加效果随种植年限的增加而极显著。【结论】有机肥替代20%化肥比常规施肥更能显著的提高土壤养分含量,有机替代处理的小麦产量较常规施肥处理略有增加但差异不显著。
【Objective】To study the effects of organic fertilizer instead of 20%fertilizer on soil nutrient content and spring wheat yield through two consecutive years of fixed-point fertilization experiments in the hope of providing scientific basis for reducing fertilizer fertility of oasis wheat in arid region.【Methods】The field experiment was carried out for two consecutive years.There were three treatments:No fertilization treatment(T 1),conventional fertilization treatment(T 2)and organic fertilizer replacing 20%fertilizer treatment(T 3)were set up.【Results】The results showed that the organic fertilizer treatment could increase wheat yield,soil available nutrient content and organic matter content by replacing 20%fertilizer with 20%fertilizer,and the organic fertilizer treatment could achieve the same effect as the conventional fertilizer application,and the increase effect of soil nutrients with the increase of planting years was very significant.【Conclusion】The results showed that organic fertilizer can significantly increase soil nutrient content by replacing 20%fertilizer with conventional fertilizer,and the yield of wheat was slightly increased but the difference was not significant.
