玉米氮肥和磷肥总量控制试验研究

Study on Total Amount Control of Nitrogen and Phosphorus Fertilizer on Maize

为了优化玉米氮肥和磷肥的适宜用量,采用田间试验,研究了氮肥和磷肥施用量对玉米产量的影响。结果表明:氮肥和磷肥的施用量对玉米产量的影响均达到显著水平,玉米产量达到最高时氮肥施用量为530.56kg·hm-2,磷肥施用量为105.45kg·hm-2。

In order to optimize the suitable amount of nitrogen and phosphorous fertilizer of maize, the effects of nitrogen and phosphorous fertilizer on the yield of maize were studied by field experiments. The results showed that the effects of nitrogen and phosphorous fertilizer amount on maize yield reached a significant level. The a- mounts of nitrogen and phosphorous fertilizer were 530.56 and 105.45 kg. hm-2 respectively when yield of maize was the highest.
