摘要
为探究新型肥料纳米控释氮肥、控释钾肥、添加剂增效磷钾肥、黄腐酸复合肥、黄腐酸液体肥对水稻生长、产量及肥料利用率的影响,以习惯施肥为对照,开展了大田小区试验。结果表明,与常规施肥相比,几种新型肥料在氮素施用量减少25%、磷素和钾素施用量相同的条件下,均可提高水稻产量及经济效益,增产6.01%~18.50%,增收895.80~3250.69元/hm 2。在试验条件下,纳米控释掺混氮肥+黄腐酸液体肥、黄腐酸复合肥+黄腐酸液体肥的施肥效果突出;以磷钾肥、腐殖酸、海泡石、硅藻土配制成的添加剂增效磷钾肥效果较好;单施纳米控释掺混氮肥或控释钾肥的施肥效果优于纳米控释掺混氮肥+控释钾肥的施肥效果;纳米控释掺混氮肥、黄腐酸复合肥配合施用黄腐酸液体肥可以提高肥料效果。
In order to explore the effects of new fertilizers,including nano-controlled-release nitrogen fertilizers,controlled-release potassium fertilizers,additive synergistic phosphate and potassium fertilizers,fulvic acid compound fertilizers,and fulvic acid liquid fertilizers on rice growth,yield and fertilizer utilization,a field plot experiment is carried out with custom fertilization as control.The results show that compared with conventional fertilization,several new fertilizers can increase rice yield and economic benefits under the condition that the nitrogen application rate is reduced by 25%and the phosphorus and potassium application rates are the same.The increase in output is 6.01%to 18.50%,and the increase in income is 895.80 to 3250.69 yuan/hm 2.Under the test condition,nano-controlled-release blended nitrogen fertilizer+fulvic acid liquid fertilizer,fulvic acid compound fertilizer+fulvic acid liquid fertilizer have outstanding fertilization effects;the additive synergistic phosphate and potassium fertilizer made of phosphate and potassium fertilizer,humic acid,sepiolite and diatomite has better effect;the fertilization effect of single application of nano-controlled-release blended nitrogen fertilizer or controlled-release potassium fertilizer is better than that of nano-controlled-release blended nitrogen fertilizer+controlled-release potassium fertilizer;application of nano-controlled-release blended nitrogen fertilizer and fulvic acid compound fertilizer combined with fulvic acid liquid fertilizer can improve the fertilizer effect.
