| 摘 要： | 通过玉米和水稻盆栽实验对改性 (氧化氨解 )造纸黑液木质素———AOL作为一种缓释氮肥的肥效进行了研究。结果表明 ,与等氮量的碳铵和尿素相比 ,AOL对盆栽玉米有着良好的增产效果 ,能够提高玉米对氮肥的利用率 ,但对盆栽水稻增产效果则不及碳铵和尿素。出现这种现象的原因正是由于AOL的缓释性和抗淋溶性。实验表明AOL是一种良好的缓释氮肥

| Abstract: | A pot experiment was conducted to study the fertilizer efficiency of Ammonia-oxidized Lignin (AOL) used as a slow-released nitrogen fertilizer on corn and rice. The result indicated that AOL could strikingly increase the yield of corn and utilization ratio of nitrogen compared with ammonium bicarbonate and urea. However, it did not seem to be as effective as that for rice. In consideration of the nature of AOL with slow-released and anti-leaching properties, it may be concluded that AOL can be regarded as an attractive slow-released nitrogen fertilizer. |
