宁南丘陵地区无公害马铃薯生产施肥技术及经济效益的研究结果表明,A级绿色马铃薯的生产中,以基施羊粪35700kg/hm2、油渣2400kg/hm2、尿素600kg/hm2的处理效果最好,其生物产量、鲜薯产量较对照分别增产82.4%、81.0%,净产值较对照增加21.2%,同时,使土壤有机质、水解氮、速效磷和速效钾含量分别较对照提高0.25g/kg、48.4mg/kg、4.4mg/kg和27.0mg/kg。该处理生产的马铃薯不仅产量高、品质好、食用安全,且经济效益显著,可作为无公害绿色马铃薯生产技术推广应用。
The results showed that the production of A-level green potato was the best with the treatments of Ji’ershi sheep manure 35700kg / hm2, oil residue 2400kg / hm2, and urea 600kg / hm2 Compared with the control, the biomass and fresh potato yield increased by 82.4% and 81.0% respectively, and the net output value increased by 21.2% compared with the control. At the same time, the contents of soil organic matter, hydrolyzed nitrogen, available phosphorus and available potassium were increased by 0.25g / kg and 48.4 mg / kg, 4.4 mg / kg and 27.0 mg / kg. The potato produced by this treatment not only has the advantages of high yield, good quality, safe consumption and remarkable economic benefits, and can be applied as a pollution-free green potato production technology.
