配方施肥对鄂西北地区马铃薯产量和经济效益的影响

Effects of formula fertilization on yield and economic benefit of potato of northwest Hubei province

为探索测土配方施肥技术在鄂西北地区马铃薯生产中的应用效果,2020年在湖北省郧西县进行大田试验,研究不同施肥配方对马铃薯产量和经济效益的影响。结果表明,与不施肥相比,习惯施肥、配方施肥1、配方施肥2的马铃薯产量和产值均显著增加,分别增加6630、8715和8040 kg/hm^(2),19890、24120、26145元/hm^(2);与农民习惯施肥相比,配方肥1、2的马铃薯产量和产值也均显著增加,分别增加2085、1410 kg/hm^(2),4230、6255元/hm^(2)。在本试验条件下,配方肥1(14-8-18)是比较适宜鄂西北地区马铃薯免耕、高产、高效栽培的施肥配方。

To explore the application effects of soil-testing formula fertilization technology on potato production in northwest region of Hubei province,field test had been conducted in Yunxi county in 2020 to provide research of effects on potato yield and economic benefit by different fertilization formulas.Results showed that,compared with no fertilization,conventional fertilization,formula fertilization 1 and formula fertilization 2 had increased potato yield and output value significantly,with an increase of 6630 kg,8715 kg and 8040 kg per hectare respectively and 19890 yuan,24120 yuan and 26145 yuan per hectare respectively.Compared with farmers conventional fertilization,potato yield and output value by formula fertilizer 1 and formula fertilizer 2 had also been increased significantly,with an increase of 2085 kg,1410 kg per hectare respectively and 4230 yuan,6255 yuan per hectare respectively.Under the conditions of this experiment,formula fertilizer 1(14-8-18)is a fertilization formula which is suitable for potato no-tillage cultivation with high-yield and high-efficiency in northwest region of Hubei province.
