| 摘 要： | 为了探明早稻种子包衣肥的缓释性能，对用其制备的包肥种子中养分N、P、K的初期释放率、微分释放率和累积释放率进行了测定。研究结果显示：包衣肥中养分的初期释放率＜40%，其中N的初期释放率最快，K次之，P释放得最慢；N、P、K的微分释放率显示包衣肥中养分能够均匀释放，能够满足早稻生长前期对养分的需求，提高肥料利用率，表明早稻种衣肥的缓释性能良好。

Slow-release Properties of Early-rice Seed-coating Fertilizer |
| |
| Abstract: | In order to explore the slow- release properties of early rice seed- coating fertilizer, the initial release rate, differential release rate and cumulative release rate of N, P and K in early rice seed-coating fertilizer were determined. The results showed that the initial release rate of early rice seed-coating fertilizer nutrients were less than 40%, the initial release rate of N was the fastest, then was that of K, and the release rate of P was the slowest. The differential release rates of N, P and K showed that the nutrients of early rice seed-coating fertilizer released evenly, which could meet the early growth demand of early-rice for nutrients and improve fertilizer use efficiency, so that the slow-release properties of early rice seed-coating fertilizer were good. |
