玉米施用生物有机肥效益研究

Benefits of Bio-Organic Fertilizer Applied in Maize

为降低生产成本、减轻土壤污染、增加农民收入,开展了玉米生产中化肥减量、增施有机肥的效益研究。结果表明:化肥减量15%、配施有机肥1800 kg/hm^(2)玉米产量最高,为12713.8 kg/hm^(2),较常规施肥增产1.4%,净收益增加558.37元/hm^(2)。减施化肥、合理增施有机肥可以提高玉米产量、增加收益。

In order to reduce production costs,soil pollution and increase income,the benefits of the implementation of fertilizer reduction and organic fertilizer application in maize production were studied in this paper.The results showed that with the fertilizer reduction of 15%and the application of 1800 kg/hm^(2) organic fertilizer,the maize yield was the highest,that is 12713.8 kg/hm^(2).The production was increased by 1.4%compared with the traditional way.The net income was increased by 558.37 kg/hm^(2).It is proved that the proper fertilizer reduction and organic fertilizer application can improve the maize yield and increase incomes.
