棋盘格上的独立树木
生成一张置于透明背景棋盘格中心、写实风格的单棵落叶树素材，适用于库存抠图或合成使用。
Create a photorealistic cutout stock image of a single mature {argument name="tree type" default="broadleaf deciduous tree"}, isolated and centered, showing the entire tree from roots to crown. The tree has a thick textured brown trunk that splits into several large upward branches, dense irregular rounded foliage, many small glossy leaves in varied {argument name="leaf color" default="bright spring green"} tones, natural shadows within the canopy, and fine visible branch details peeking through the leaves. Use even studio-style daylight, sharp focus, high detail, no ground, no landscape, no people, no text. Place it on a {argument name="background style" default="transparent-background preview checkerboard"} made of subtle light gray and white squares, as if displaying a PNG asset with transparency. Composition: square canvas, tree centered vertically and horizontally, crown nearly fills the upper width, trunk centered in the lower third, clean object-cutout edges, realistic botanical proportions. 生成一张照片级写实的单棵成熟 {argument name="tree type" default="阔叶落叶树"} 抠图素材，居中独立显示，展示从根部到树冠的完整树木形态。树木拥有粗糙且纹理分明的棕色树干，向上分叉出几根粗壮的枝干，树冠茂密且形状不规则，布满许多深浅不一的 {argument name="leaf color" default="明亮的春绿色"} 光泽小叶，树冠内部带有自然阴影，枝叶间隐约可见精细的枝条细节。使用均匀的摄影棚日光照明，对焦清晰，细节丰富，无地面，无景观，无人物，无文字。将其放置在由浅灰色和白色方块组成的 {argument name="background style" default="透明背景预览棋盘格"} 上，呈现出类似 PNG 透明素材的展示效果。构图：方形画布，树木垂直和水平居中，树冠几乎填满上方宽度，树干位于下三分之一处中心，物体边缘抠图干净，符合真实的植物学比例。
