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。 The effects of different fertilization treatments on phosphorus uptake by plants and their yield at jointing and maturing stages of maize were studied by field root bag test. The results showed that microbial inoculum, humic acid and organic-inorganic compound fertilizer could increase the phosphorus uptake of maize plants. Compared with N, P and K fertilizers, the uptake of P by plants increased by 13.7% -41.5% , Humic acid and organic-inorganic compound fertilizer increased corn yield and improved corn quality.
