应用不同培养法研究了有机肥料的氮素释放特点，并与盆栽试验的作物吸氮量进行相关分析。结果表明，好气和厌气培养法在２个月内氮素释放累积趋势比较一致。符合ｙ＝ｘ／（ａ＋ｂｘ模型，与作物吸氮的相关性培养７ｄ即可达显著水平。好气培养—间歇淋洗法氮素释放累积量在一年内符合ｙ＝ａ＋ｂｘ模型，时间再长便符合ｙ＝ｘ／（ａ＋ｂｘ）模型。与作物吸氮量的相关性在一个月后达显著水平，４个月以后达极显著水平。 Application of different culture methods to study the characteristics of organic fertilizer nitrogen release and pot experiments with crop nitrogen uptake correlation analysis. The results showed that the aerobic and anaerobic culture methods showed a consistent trend of nitrogen release in two months. According to the model of y = x / (a ​​+ bx, the correlation with crop nitrogen uptake reached a significant level after 7 days of incubation, and the aerobic culture-intermittent leaching method accorded with y = a + bx model within a year, y = x / (a ​​+ bx) model. The correlation with crop nitrogen uptake reached a significant level in one month and reached a significant level in four months.
