摘要:

肥料深施是提高粮食产量和氮素利用率的关键要素。鉴于当前临海地区化肥种类繁多、施肥方式多样,通过田间试验,研究不同肥料与不同施肥方式相结合对水稻产量及土壤肥力的影响。结果表明,惠多利复合肥深施(HS)和惠多利复合肥减量深施(HSJ)对水稻增产效果明显;茂施缓释肥一次性深施(MSY)显著增加了稻谷含氮量。因此,水稻产量及养分吸收受肥料类型和施肥方式的影响较大。茂施缓释肥减量深施(MSJ)提升pH值的同时也显著提升了土壤有机质、全氮、有效磷、速效钾含量。综上所述,HS和HSJ施肥处理的株高和穗长增效显著且显著提升水稻产量,建议在后续生产中进行推广。

Abstract:

Deep application of fertilizers is a common strategy to improve grain yield and nitrogen use efficiency. In view of the variety of fertilizer and the variety of fertilizer application methods in Linhai area, this study studied the effect of different fertilizer and different fertilizer application methods on rice yield and soil fertility through field random block experiment. The results showed that the side-deep placement of Huiduoli compound fertilizer (HS) and the side-deep placement of Huiduoli compound fertilizer reduction (HSJ) had obvious effects on rice yield increase; while the one-time side-deep placement of Moith slow-release fertilizer (MSY) significantly increased the nitrogen content of rice. Therefore, rice yield and nutrient uptake were significantly affected by fertilizer types and fertilization methods. In terms of soil nutrients, the effect of Moith slow-release fertilizer reduction and side-deep placement (MSJ) significantly increased pH value, and also significantly increased soil organic matter, total nitrogen, available phosphorus, and available potassium. HS and HSJ fertilization treatments showed significant efficiency gains in plant height and spike length and significantly increased rice yield, which is recommended for subsequent agricultural production.
