| 摘 要： | 于2005-2006年用氮肥模拟农家肥(牛粪)在稻田中的氮素释放,结果表明:1)以设计农家肥在前期释放30%～50%的处理水稻产量为10.751～10.763 t/hm2,高于以农家肥在前期释放70%的处理(10.083 t/hm2),说明,农家肥在前期释放氮素较少,而进入孕穗期后释放较多.2)以用农家肥与无机化学氮,水稻产量为最高,达到11.283 t/hm2,而用农家肥产量为6.757 t/hm2.说明,用农家肥与无机化学氮混合施用可有效提高水稻产量.进一步研究表明:农家肥与氮肥配合施用后,在孕穗期后氮的吸收利用率为最高. |

| Abstract: | The urea used as farmyard manure was applied to study the effect of different nitrogen release condition on rice yield.The results showed that the yield with applying 30% to 50% nitrogen before booting was 10.751 t/hm2 to 10.763 t/hm2,higher than 10.083 t/hm2 with applying 70% nitrogen before booting because applying ear fertilizer was beneficial to yield increase,and the yield with applying farmyard manure and inorganic fertilizer was the highest(11.283 t/hm2),significantly higher than 6.757 t/hm2 with onl... |
