有机无机复合肥及调节剂对玉米产量及磷素吸收的影响

Effects of Regulating Factors on Maize P Uptakes and Its Yield

通过田间根袋试验,研究了不同施肥处理对玉米拔节期和成熟期植株吸磷量及其产量的影响。结果表明,施用微生物菌剂、腐植酸和有机无机复合肥能增加玉米植株吸磷量,与施氮磷钾肥料处理相比,植株吸磷量增加幅度为13.7%～41.5%;施用微生物菌剂、腐植酸和有机无机复合肥增加了玉米产量,提高了玉米品质。

Rhizobox experiments were conducted to study P uptakes of root and output during the jointing and mature periods,when microbial fertilizer,Humic acids and organic-mineral fertilizer were used as regulating factors.The results showed that the output of maize and P uptakes of root respectively increased after applying the above fertilizer,which was beneficial to improve maize quality.
