| 摘 要： | 采用埋土试验法和微区试验方法,对矿物包裹复合肥料的缓释性进行了研究。结果表明,矿物包裹复合肥料的养分释放明显向后期延伸,矿物包裹复合肥料的肥效期可达120 d以上,比复混合肥料的肥效期至少延长80 d,有利于植物均衡吸收养分,其氮的利用效率比等养分复合肥高出38个百分点;其磷的利用效率比等养分复合肥高出11.5个百分点。

| Abstract: | Slow release effects of mineral coated slow release compound fertilizer were studied by micro-plot experiment and burying-earth experiment. The results showed that the nutrient releasing postpone to anaphase obviously. Effect period of mineral coated slow release compound fertilizer for crop may was more than 120 days. Effect period of it prolong at least 80 days than compound fertilizer. It is favorable to the balancing absorption of plants nutrient. Efficiency of nitrogen utilization of coated slow release compound fertilizer was 38 percentile higher than that of compound fertilizer. Efficiency of phosphorus utilization of coated slow release compound fertilizer was 11.5 percentile higher than that of compound fertilizer as same nutrient. |
