A kind of composite multi-layer fertilizer structure is that plural kind of fertilizer is integrally pressed into fertilizer unit, and pre-buried planted in the soil with self-restraint plants crop； Wherein the fertilizer unit includes: substrate fertilizer, the upper layer of position what fertilizer unit, to decompose soil poisoning element and improvement soil property； All one's life fleshes up, the second layer of position what fertilizer unit, plants the root, stem, the Ye Chengchang that plant crop to promote； Crop flowers, result are planted to promote to plant by one flowers and fruits fertilizer, the lower layer of position what fertilizer unit. Accordingly, the stage growth for planting crop is planted in cooperation, and fertilizer nutrient needed for discharging different phase growth in due course provides plant and plants crop better growing conditions.一種複合多層肥料結構，係將複數種肥料一體壓製成肥料單元，預埋在土壤中以涵養植栽作物；其中該肥料單元包括：一基底肥，位於肥料單元之上層，用以分解土壤中毒素及改良土質；一生長肥，位於肥料單元之第二層，用以促進植栽作物之根、莖、葉成長；一花果肥，位於肥料單元之下層，用以促進植栽作物開花、結果。據此，配合植栽作物之階段成長，適時釋放不同階段生長所需之肥料養分，提供了植栽作物良好的生長條件。
