2004-2005年在辽宁省鞍山、辽中地区进行水稻辅助一次性全层高效施肥试验,结果表明,水稻插秧前的水耙田前一次性全层施高活性腐植酸型长效缓释水稻专用肥、辅以在水稻秧苗插秧后10～15天追施尿素的施肥技术,与常规传统“少吃多餐”的多次施肥方法相比,水稻增产增效显著;在高肥力土壤地块以施长效缓释水稻专用肥750kg/hm2、追施尿素150.0kg/hm2产量最高,中等肥力土壤地块施长效缓释水稻专用肥825kg/hm2、追施尿素187.5kg/hm2产量最高,低肥力土壤地块施长效缓释水稻专用肥900kg/hm2、追施尿素187.5kg/hm2产量最高。
2004-2005 in Anshan, Liaoning Province, Liaozhong region of rice-assisted one-time full-height and high-efficiency fertilizer application, the results showed that before transplanting rice paddy before the one-time full-layer high activity humic acid long-term slow release rice Fertilizer, supplemented by 10 to 15 days after rice seedling transplanting urea fertilization technology, and conventional traditional “eat less meals,” compared to multiple fertilization methods, rice yield and efficiency significantly; in high-fertility soil The results showed that the yield of paddy rice was 750kg / hm2 and topdressing urea was 150.0kg / hm2. The medium fertility soil plot was applied with 825kg / hm2 of special fertilizer for long-release slow-release rice and 187.5kg / hm2 of topdressing urea. Long-term application of land-effect slow-release rice special fertilizer 900kg / hm2, topdressing urea 187.5kg / hm2 yield the highest.
