摘要：

在农业农村部化肥“零增长”背景下,基于氮肥减量、水稻稳产和减少施肥次数要求的轻简化施肥方式对于肥料产品有更高的要求。本试验通过对杂交水稻施用不同品牌缓释肥稻坚强(N 26%、P2O5 10%、K2O 15%),好乐耕(N 18%、P2O5 5%、K2O 10%),绿聚能(N 26%、P2O5 10%、K2O 15%),威斯(N 26%、P2O5 10%、K2O 15%)等氮对比试验,探究其对产量及肥力提升效果。结果表明,4个品牌的缓释肥在不同田块、不同水稻品种上应用效果有些许差异,分水镇里湖畈(水稻品种为甬优12)中,籽粒干产量最高的处理是威斯,产量为9 761.9 kg·hm-2,相比不施肥(CK)高43.5%,相比常规施肥(NPK)高1.6%。百江镇冷水畈(水稻品种为甬优15)的试验点也有相似的规律,产量最高的处理亦是威斯,为9 542.7 kg·hm-2,相比不施肥(CK)高44.5%,相比常规施肥(NPK)高4.1%。而施用其他缓释肥品牌时,水稻产量与NPK没有明显差异。

Abstract:

Under the background of “zero growth” of fertilizers in the Ministry of Agriculture and Rural Affairs of PRC, light and simplified fertilization methods based on the requirements of nitrogen reduction, stable rice yield and reduced fertilization times have higher requirements for fertilizer products. In this experiment, the effects of different brands of slow-release fertilizers on the yield and fertility of hybrid rice were explored through the comparative test of nitrogen, such as Dao Jianqiang (N 26%、P2O5 10%、K2O 15%), Hao Legeng (N 18%、P2O5 5%、K2O 10%), Green Energy (N 26%、P2O5 10%、K2O 15%), Wei Si (N 26%、P2O5 10%、K2O 15%).The results showed that the application effects of the four brands of slow-release fertilizer on different fields and different rice varietiesare were slightly different. In Lihu field, Fenshui Town (rice variety Yongyou 12), the treatment with the highest dry grain yield was Wei Si, with a yield of 9 761.9 kg·hm-2, which was 43.5% higher than no fertilizer (CK) and 1.6% higher than conventional fertilization (NPK).Similar rules were also observed in the test site of Leng Shui field (rice variety Yongyou 15) in Baijiang Town. The highest yield was also Wei Si, which was 9 542.7 kg·hm-2, 44.5% higher than no fertilizer (CK) and 4.1% higher than conventional fertilizer (NPK). When other slow-release fertilizer brands were applied, there was no significant difference in rice yield compared with the conventional fertilization (NPK).
