摘要： 为探究缓释肥处理对浙中地区双季稻产量和化肥利用率的影响,于2022年开展田间试验,试验共设8个处理。结果表明:在早稻季,与不施氮肥(ZPK)相比,不施磷肥(ZNK)、不施钾肥(ZNP)和施缓释肥(ZHLG)处理的籽粒产量分别提高了45.42%、43.59%和70.33%;ZHLG处理氮、磷、钾肥利用率分别为40.94%、27.10%和72.50%。在晚稻季,施缓释肥(WHLG)处理水稻667 m2籽粒产量最高,为536.3 kg,与晚稻不施氮肥(WPK)处理相比提高了6.81%。WHLG处理氮、磷、钾肥利用率分别为41.00%、21.50%和73.50%。综上,在浙中地区双季稻生产过程中施用缓释肥可有效提高水稻产量和氮肥利用率,是一种更为科学合理的施肥方式。

Abstract:

In order to investigate the effects of slow-release fertilizer on double-cropping rice yield and fertilizer utilization rate in central Zhejiang, a field trial was conducted in 2022, and 8 treatments were set. In the early rice season, the grain yields of ZNK, ZNP and ZHLG treatments increased by 45.42%, 43.59% and 70.33%, respectively, compared with ZPK treatment. The fertilizer utilization efficiency of nitrogen, phosphorus and potassium in ZHLG treatment was 40.94%, 27.10% and 72.50%, respectively. In the late rice season, the grain yield of 667 m2 of rice treated with WHLG was the highest, which was 536.3 kg, 6.81% higher than that of WPK treatment. The fertilizer utilization efficiency of nitrogen, phosphorus and potassium in WHLG treatment was 41.00%, 21.50% and 73.50%, respectively. In conclusion, the application of slow-release fertilizer in the production process of double cropping rice in central Zhejiang can effectively improve rice yield and nitrogen fertilizer use rate, which is a more scientific and reasonable fertilization method.
