摘要：

为了探索‘保大麦20号’最佳及最有效的化肥施用量,在其他条件相同的情况下,设7个处理,进行大麦化肥减量试验。结果表明：（1）减少肥料用量10%的处理产量最高,减少肥料用量20%的处理其次,正常施肥水平的处理居第三位;（2）减少化肥用量20%的处理显著低于减少化肥用量10%的处理,但显著高于其他所有处理,其他减少化肥用量的处理随着化肥用量的减少产量随之减少;（3）投入产出比随着化肥用量的减少而增加,减少化肥用量10%、20%的处理收益较大;（4）减少化肥用量10%、20%的处理,穗实粒数及千粒重高于正常施肥水平的处理。在生产中,‘保大麦20号’可以减少化肥用量10%~20%,达到节本增效的目的。

Abstract:

To explore the best and most effective fertilizer application amount for barley variety ‘Baodamai.20’, 7 treatments were set up to reduce fertilizer application in barley production under other conditions being the same. The results showed that: (1) the treatment with 10% fertilizer reduction had the highest yield, followed by 20% fertilizer reduction treatment and then the normal fertilizer level treatment; (2) the yield of 20% fertilizer reduction treatment was significantly lower than that of 10% reduction treatment, but significantly higher than that of other treatments, whose yield declined with the decrease of fertilizer amount; (3) the input-output ratio increased with the decrease of fertilizer, and 10% and 20% fertilizer reduction had relatively big benefit; (4) 10% and 20% fertilizer reduction had higher number of grains per ear and 1000-grain weight compared with the normal fertilizer level treatment. For ‘Baodamai 20’, the goal of cost-efficiency could be achieved by reducing fertilizer application for 10%-20%.
