| 摘 要： | 分析了树脂和硫磺包裹尿素缓释肥料发展缓慢的原因和弊端，提出以水溶性聚合物作为尿素和复混肥料的包膜、胶结和内质缓释剂，具有降解快、对作物无害、改善土壤结构、成本低等特点，将促进缓释肥料的发展。采用生产不同时间段释放养分的缓释肥，按作物不同生育期对养分的需求比例掺混在一起，生产作物专用的缓／控释BB肥料简单易行，应是我国缓／控释肥料的发展方向。

| Abstract: | The reasons about the slow development and disadvantages of resin and sulphur coated urea are analyzed. Taking water-soluble polymer as the coating,cementing and endoplasm material for urea and compound fertilizer,it has fast rate of degradation,harmless for crops, improving the structure of soil,low cost, etc; and it will promote the development of controlled release fertilizer. The production of crop specific controlled release BB fertilizer is simple and easy to do by mixing different nutrient-lapsed tim... |
