中科院沈阳生态研究所技术稳定性长效复合肥该技术主要是通过脲酶抑制剂和硝化抑制剂来调节土壤中的脲酶硝化和亚硝化细菌活性,一方面推迟氮素的释放高峰期,达到作物的需肥高峰与肥料释放高峰相吻合,另一方面减少氮素的淋溶损失,提高土壤中氨离子浓度的机理,减少了肥料的损失与浪费,从而大大提高肥料的利用率。稳定性专用肥实现一次基施,免追肥,满足作物整个生育期对养分需要,达到前期(苗期)控制地上生长,促进生根;中期(营养生殖期)供应充足, Shenyang Institute of Ecology, Chinese Academy of Sciences, the stability of long-term compound fertilizer The technology mainly through urease inhibitors and nitrification inhibitors to regulate soil urease nitrification and nitrification bacteria activity, on the one hand to postpone the nitrogen release peak, to crop Fertilizer peak and peak fertilizer release coincide, on the other hand reduce the leaching loss of nitrogen to improve soil ammonia ion concentration mechanism, reducing the loss and waste of fertilizers, thereby greatly improving fertilizer utilization. Stability of special fertilizer to achieve a basic facilities, no top dressing, to meet the needs of crops throughout the growing season on the nutrient needs to reach the pre-(seedling stage) control of ground growth and promote rooting; mid-term (vegetative period) adequate supply,
