摘要
为研究化肥减量配施有机肥对马铃薯生产效益的影响,以常规施肥为对照,设置4个有机肥配施处理,研究了土壤养分、马铃薯产量和经济效益的差异。结果表明,施用一定量的有机肥能够显著提高土壤碱解氮、速效磷和速效钾含量,T1处理的马铃薯产量显著高于CK处理,而常规施肥处理的经济效益均高于配施有机肥处理。因此,常规施肥仍是现阶段马铃薯获得最大经济效益的最佳方案,化肥减量配施有机肥对改善土壤肥力效果明显,以农家肥配合化肥施用也能取得理想的收益,是促进可持续发展的必要趋势。
In order to study the effect of fertilizer reduction combined with organic fertilizer on potato production efficiency,the differences of soil nutrients,potato yield and economic efficiency were studied by setting 4 organic fertilizer treatments compared with conventional fertilization.The results showed that a certain amount of organic fertilizer could significantly increase the content of soil alkali-hydrolytic nitrogen,available phosphorus and available potassium.The potato yield of T1 treatment was significantly higher than that of CK treatment,and the economic benefit of conventional fertilizer treatment was higher than that of combined organic fertilizer treatment.Therefore,conventional fertilization is still the best plan to obtain the maximum economic benefits for potatoes at this stage,fertilizer reduction combined with organic fertilizer has obvious effect on improving soil fertility,and the application of farm fertilizer combined with chemical fertilizer can also obtain ideal benefits,which is a necessary trend to promote sustainable development.
