| 摘 要： | 采用田间试验的方法,研究了杂交中稻广两优香5的营养特性与施肥效应。结果表明,在生育前期广两优香5对氮、磷需求量大,中后期钾素吸收增加;养分对其产量构成因子的影响上表现为氮钾磷;结合模拟的最佳施肥量和经济施肥量,推荐了江汉平原地区中等肥力条件下的施肥量为氮170~200 kg/hm2、磷70~100 kg/hm2、钾105~135 kg/hm2。

| Abstract: | The paper researched the nutrition characteristics and fertilizer effect for hybrid rice Guangliangyouxiang 5 by field experi- ment. The results showed that Guangiliangyouxiang 5 needs more nitrogen and phosphorus in early growth stage, more potassium in late growth stage. Fertilizer effect on yield components is N 〉 K 〉 P. Combined with the simulate optimum and economical amount of fertilizer, the recommended amount of fertilizer is N 170-200 kg/hm^2, P2O5 70-100 kg/hm^2, K2O 105-135 kg/hm^2. |
