| 摘 要： | 研究不同氮磷钾配比及施肥量对中棉所41产量及光合特性的影响。结果表明,在N∶P∶K=1∶0.8∶0.6条件下,随着氮肥用量的减少,产量随之下降。在同样氮肥用量的情况下,不同P,K配比,产量表现不同,在高肥情况和低肥情况下均表现为磷肥增产效应比钾肥明显。在花铃期测定光合特性变化规律与产量表现一致。在同样肥料用量情况下,16叶期1次追施氮肥,皮棉产量最高,达到1648.61kg/hm2。

| Abstract: | The effect of different ratio N∶P∶K on the yield and photosynthetic characteristics of cv. Zhongmian 41 was studied, The result showed that the yield was decreased with the reducing of N fertilizer application at the ratio of N∶P∶K = 1 ∶0.8∶0.6. The yield was different at different ratio of P∶K with the defined N application. In the condition of both heavy and low fertilizers, the effect of P application on the yield increasing was more obvious than that of K application. At the phase of flowering and boll-setting, the changing rule of photosynthetic characteristics monitored was consistent with that of the yield. In the condition of the same fertilizer application, at the stage of 16-leaf-age, the lint yield was the highest (1 648.61kg/hm~2) by additional N application. |
