摘要
以陇塬235新品种为基础,采用“纳米Fe微肥拌种+叶面喷施”,并减少化肥用量10%~60%进行试验。结果表明,化肥减量10%、20%和30%的小区均优于空白对照组,分别增产9.5、7.1、2.3 kg,增产率分别为2.08%、1.56%和0.5%。其中,化肥减量10%的小区表现最佳,适合大面积推广。
Based on the new variety Longyuan 235,experiments were conducted by using nano Fe micro-fertilizer for seed dressing and foliar spraying,and reducing the use of chemical fertilizers by 10%to 60%.The results showed that the plots with a 10%,20%and 30%reduction in chemical fertilizer use were all superior to the blank control group,with increased yields of 9.5,7.1 and 2.3 kg respectively,and the increase rates were 2.08%,1.56%and 0.5%respectively.Among them,the communities that had reduced the use of chemical fertilizers by 10%perform the best and were suitable for large-scale promotion.
