Abstract:

针对宁夏平罗西大滩盐碱荒地改良利用问题,研究了施用不同有机肥后对盐碱土壤的改良状况及对水稻生长和产量的影响。结果表明:与单施化肥相比,5个有机肥配施化肥处理均有显著改良提升盐碱土的效果。其中,化肥配施生物有机肥处理显著(p < 0.05)提高了土壤有机质和碱解氮、速效磷、速效钾养分含量,降低了0~20 cm土壤全盐和交换性钠的含量,极显著(p < 0.01)的降低了土壤pH值,有效改善了土壤活性。水稻产量达到7290 kg/ha,增产295%。
Against the problem of Ningxia Pingluo Xidatan saline-alkali wildlands utilization, this paper stu-died the effects of applying different organic manure application on the soil amelioration, rice growth and yield. The results showed that, comparing with the chemical fertilizer, five kinds organic manure mixed chemical fertilizer treatment significantly improved and enhanced the saline- alkali soil. Among them, bio-organic fertilizer mixed chemical fertilizer treatment significantly (p < 0.05) increased soil organic matter and N, P and K nutrient content, reduced the total salt and exchangeable sodium content of 0 - 20 cm soil, extremely significantly (p < 0.01) reduced the soil pH, and effectively improved the soil activity. Rice production reached 7290 kg/ha, increasing 295%.
