1. 苗木应用的增值效益
1. Value-added benefits of seedling application
以前园林中用了不少易老化的树种，越长越不值钱，现在就要多考虑如何对不同等级的苗木进行高效应用，从而实现苗木增值。
In the past, many kinds of trees were used in gardens, and the longer they grow, the less valuable they are. Now, we should consider how to apply different grades of seedlings efficiently, so as to realize the value-added of seedlings.
2. 时间艺术的增值效益

植物设计适当选取小规格全冠苗，通过时间的作用，创造出生长变化的景观，实现植物景观的持续升值。
In plant design, small size full-crown seedlings are selected appropriately. Through the function of time, the landscape of growth changes is created, and the continuous appreciation of plant landscape is realized.
3. 生态平衡的增值效益
3. Value-added benefits of ecological balance
通过植物自我生长，实现景观效果的持续优化，最终实现植物的自我稳定，形成兼具生态性和景观性的效果。
Through the self-growth of plants, the sustainable optimization of landscape effect is realized, and the self-stability of plants is finally realized, which has both ecological and landscape effects.
