不同施肥方式对晚稻肥料利用效率的影响

Effects of Different Fertilization Methods on Fertilizer Utilization Efficiency of Late Rice

2022年开展了晚稻不同施肥模式肥料利用率田间试验,结果表明,在平衡施肥条件下,基肥侧深施用可促进水稻早期发育,确保生长量和分蘖茎数,提高了产量,比基肥常规施用增产4.6%,肥料贡献率提高3.5%,氮磷钾肥料利用率分别提高0.16%、1.13%、0.13%。

In 2022,a field trial on fertilizer utilization rate of late rice with different fertilization modes was carried out.The results showed that under the condition of balanced fertilization,the side deep application of base fertilizer promoted the early development of rice,ensured the growth amount and the number of tillers,and increased the yield.Compared with the conventional application of base fertilizer,the yield increased by 4.6%and the contribution rate of fertilizer increased by 3.5%.The utilization rate of nitrogen,phosphorus and potassium fertilizer was increased by 0.16%,1.13%and 0.13%,respectively.
