| 摘 要： | 为提高氮肥利用率,探讨蓄肥改土剂对水稻的应用效果,以水稻品种五优稻4号为材料,采用二因素裂区试验设计,研究了不同型号蓄肥改土剂及不同尿素施用量对五优稻4号生长的影响。结果表明:3种型号蓄肥改土剂均能提高氮肥利用率,五优稻4号水稻品种施用蓄肥改土剂后,节约尿素25%,即可达到稳产的效果,节尿素25%和节钾肥30%组合也可达到稳产效果。

| Abstract: | In order to improve nitrogen use efficiency and explore application effect of soil additive for nutrient retention on rice ,taking rice variety Wuyoudao 4 as test material ,the effect of different soil additive for nutrient retention and urea application amount on growth of Wuyoudao 4 were studied .The results showed that three types of soil additive for nutrient retention could improve nitrogen use efficiency .After applying soil additive for nutrient retention ,75% urea application amount could reach stable yield ,75% urea application amount＋70% potassium application amount could also reach stable yield . |
