摘要
研究表明,施肥处理1年后,施有机肥的土壤中有机态氮组分含量最高,其次是沸石配施化肥,单施化肥和对照最低。施有机肥1年后水稻产量和吸氮量仍保持高水平,沸石配施化肥也可提供水稻第二年生长所需氮素,而单施化肥和沸石则不能。
The research showed that organic nitrogen composition was the highest in applied organic fertilizer,zeolite with fertilizer was second and only appling fertilizer and control was the lowest after one year soil treated. The rice yield and nitrogen uptake were still high level after applied organic fertilization one year . Zeolite with fertilizer could supply rice nitrogen requirement of the next year, but the only appling fertilizer coundn't.
