摘要
缓控释肥是一种高效且环保的新型肥料,在解决当前我国花生种植中存在的肥料利用率低、劳动强度大、环境污染等问题方面具有显著优势。为推动缓控释肥在花生种植中的广泛应用,阐述了缓控释肥施用量、施用方式及组配对花生产量和品质的影响及其机制。适宜的缓控释肥施用量能显著提高花生产量,并改善子仁品质;施肥方式的优化,如深施和分层条施,可以提高缓控释肥的增产效果;缓控释肥与速效肥或有机肥合理配施,能有效满足花生不同生育期对养分的需求。此外,还提出了未来应重点关注的研究方向,包括深入探讨缓控释肥对花生品质影响的内在机制,研发适合花生的专用缓控释肥及相关施肥技术,构建缓控释肥的应用评价体系。这些研究将进一步推动缓控释肥在花生种植中安全、有效、广泛使用。
Slow/controlled release fertilizer is an efficient and environmentally friendly new type of fertilizer,which has significant advantages in solving the problems of low fertilizer utilization,high labor intensity,and environmental pollution in peanut cultivation in China.To promote the widespread application of slow/controlled release fertilizers in peanut cultivation,the effects and mechanisms of slow/controlled release fertilizers application rate,application methods,and combination on peanut yield and quality were elaborated.Appropriate application of slow/controlled release fertilizers can significantly increase peanut yield and improve kernel quality.The optimization of fertilization methods,such as deep application and layered strip application,can improve the yield increasing effect of slow/controlled release fertilizers.Reasonable combination of slow/controlled release fertilizers and quick acting fertilizer or organic fertilizer can effectively meet the nutrient requirements of peanut at different growth stages.In addition,research directions that should be focused on in the future were proposed,including in-depth exploration of the intrinsic mechanism of the impact of slow/controlled release fertilizers on peanut quality,development of specialized slow/controlled release fertilizers and related fertilization technologies suitable for peanuts,and construction of an application evaluation system for slow/controlled release fertilizers.These studies will further promote the safe,effective,and widespread use of slow/controlled release fertilizers in peanut cultivation.
