What are the choices and combinations of plants in the lawn?

The plants planted on the lawn should first adapt to the local external environmental factors; Secondly, it must be coordinated with the position of the lawn and the color matching should be appropriate, otherwise it will affect the greening effect and lose its ornamental value.

Firstly, according to the external environmental factors of the lawn, the plant species in the lawn are selected.

1. Choose different tree species according to different lighting conditions. For example, for lawns with poor lighting conditions, shade-tolerant tree species such as pearl plum, nanmu and cypress should be selected.

2. Choose different tree species according to the terrain conditions of the lawn, such as: choose water-resistant and moisture-resistant tree species such as paulownia, Metasequoia glyptostroboides, Pterocarya stenoptera, weeping willow, etc. in low-lying areas; In the windward mouth, choose low shrubs or deep-rooted cold-resistant trees.

3. According to the difference of soil fertility and pH value, choose fertile or barren-tolerant tree species, acid-tolerant or calcareous tree species.

4. Generally, trees with strong germination ability, such as torch tree, are not planted in the lawn, so as not to increase the difficulty of lawn management.

Second, the plants selected in the lawn must be in harmony with the position of the lawn.

1. In the lawns of squares and parks, we should pay attention to the selection of trees with high ornamental value and good shading effect, such as cedar, ginkgo, paulownia, etc. In schools and memorial gardens for martyrs, we should choose trees with strong symbolic significance, such as planting peach trees and purple-leaf plums on the school lawn to symbolize that peaches and plums are all over the world, while planting more pines and cypresses on the lawn of memorial halls for martyrs to set off solemnity.

2. In factories, roadsides and other heavily polluted lawns, tree species that can resist pollution and absorb toxic substances, such as paulownia, Sophora japonica, hibiscus, Albizia Albizia and other trees with good noise resistance and dust absorption effect, should be selected in a targeted manner, while in factory lawns polluted by sulfur dioxide, tree species with strong sulfur dioxide resistance, such as Lagerstroemia indica, Podocarpus, Pinus bungeana and peach trees, are suitable for planting.

3 oil depots, gas stations and other places of lawn, should choose ginkgo, boxwood and other fire-resistant tree species.

Thirdly, according to the color of plants, matching the color of plants in the lawn garden is the main component of its ornamental value. If used properly, it can play a very good role. When planting colorful plants in the lawn, we should first pay attention to the different feelings brought by different colors, such as: green gives people a refreshing, calm and soft feeling, and red gives people a stimulating, unrestrained and warm feeling. Secondly, we should pay attention to the different effects of color contrast and coordination, plant plants with obvious color differences in the lawn, and compare them with each other to highlight their own characteristics and make people feel eye-catching and excited; Planting plants with similar colors can have a harmonious, integrated and cordial effect, such as planting peach blossoms, crape myrtle, red maple, winter jasmine and forsythia on the lawn outside the stadium. Lawns in sanatoriums and elderly activity areas are decorated with wisteria, hibiscus and iris. , all adopt the above methods to achieve the required completely different effects.

Fourth, when planting plants on the lawn, we should also grasp the scale of quantity, not only to achieve the expected effect, but also to take into account the shape of solitary trees and the layout of overgrown plants according to the surrounding buildings and facilities. In short, through the selection and collocation of plants in the lawn, a multi-level and three-dimensional mixed artificial plant community of arbor, shrub and grass is formed, which not only breaks the single and rigid color harmony pattern of the lawn, but also increases the green quantity of the green space.
