摘要
以早稻中早 39 为试验材料,在黄岩区院桥镇开展肥效试验,探究在常规施肥与配方施肥条件下的肥料利用率.结果表明,在比常规施肥养分投入减少 51 kg·hm-2 条件下,配方施肥早稻产量为 7 386 kg·hm-2,比常规施肥产量的 7 277 kg·hm-2,增加 109 kg·hm-2.利用差减法得出,配方施肥处理的氮肥、磷肥、钾肥利用率分别是 38.7%、41.0%、85.7%,其中氮肥、钾肥利用率分别比常规施肥提高了 6.0 和 24.1 百分点,磷肥利用率比常规施肥降低了 1.0 百分点,需进一步提升肥料利用率.
Abstract
This study used early rice Zhongzao 39 as the experimental material and conducted a fertilizer efficiency experiment in Yuanqiao Town,Huangyan District,to explore the fertilizer utilization efficiency under conventional and formula fertilization conditions.The results showed that under the condition of reducing nutrient input by 51 kg·hm-2 compared with conventional fertilization,the yield of early rice under formula fertilization was 7 386 kg·hm-2,which was an increase of 109 kg·hm-2 compared with the yield of 7 277 kg·hm-2 under conventional fertilization.According to the difference method,the utilization rates of nitrogen fertilizer,phosphorus fertilizer,and potassium fertilizer in the formula fertilization treatment were 38.7%,41.0%,and 85.7%,respectively.Among them,the utilization rates of nitrogen fertilizer and potassium fertilizer were 6.0 and 24.1 percentage points higher than conventional fertilization,and the utilization rate of phosphorus fertilizer was 1.0 percentage point lower than conventional fertilization.Further improvement of fertilizer utilization rate is needed.
