| 摘 要： | 为获得超级杂交稻最佳的N肥用量,试验用中浙优一号为材料,设置6个不同处理,比较各处理对中浙优1号产量及相关性状的影响.结果表明,不施N肥或单一施用N肥,不施P、K肥,产量均较低,在P、K肥使用量固定的情况下,随N肥用量增加,产量有增加的趋势.施纯N量为180 kg/hm2的处理产量最高,并与其他处理有显著差异,当N肥用量过大,使用量超过纯N 240 kg/hm2时,产量反而降低.

| Abstract: | In order to obtain the best N fertilizer application rate in super hybrid rice, Zhongzheyou no.1 was took for experimental materials and six different treatments was set up. Comparison of effects of these treatments on Yield and Related characters of Zhongzheyou no. l was carried out .The results showed that without application of N fertilizer or a single application of N fertilizer with no P, K fertilizer, yields was lower. In the situation of P, K fertilizer fixed amount, yields were increasing gradually ... |
