The lawns formed by artificial planting of herbaceous plants or artificial transformation of natural grasslands, which have the function of beautifying the environment and ornamental value, have gradually become “a symbol of civilized life, a paradise for sightseeing and resting, a guardian of the ecological environment, and a cradle for athletes”.
一. Designing lawns and creating garden landscapes
The geometric shape of the lawn can be used to design various regular lawn flowerbed landscapes, and various irregular lawns can adjust the density and depth of the scenery. This is one of the most expressive and most used gardening techniques. In addition to using green as the background, the color of the lawn is mainly used to design the landscape. The brightness and purity of the lawn color. The brightness of the lawn grass color varies with its variety. In addition. The direction of the lawn grass blades can be changed by trimming and suppressing, thus presenting different shades of color. By using lawn grasses of different textures to create shapes, even if they are all green, people can tell the difference at a glance, just like adding darker patterns on a dark background, the artistic effect is different.
In the design of lawn landscape, attention should be paid to spatial contrast, volume contrast and color contrast. At the same time, the shape, undulation, color and organizational characteristics of the lawn can be used to reconcile, so as to form a landscape with virtual and real contrast and sparse and dense alternation. The plasticity of the lawn can soften the rigid lines of the building and enrich the artistic composition of the building. Lawns are generally used in modern gardens, and other plants are often needed to design the garden landscape. The lawns are arranged on both sides of the main road of the garden, making the main road wider and the space more open. When arranging lawns beside the path, low shrubs are needed to raise the facade landscape of the main road. At this time, the path and the terrain are combined to design a curve, which can create the artistic conception of “winding paths leading to secluded places”. Therefore, lawns combined with flowers, shrubs and trees can often create a multi-layered landscape.
二. Fine planting to ensure lawn growth
There are four planting methods: sowing, planting, laying grass blocks and laying grass rolls. For the sowing method, seed selection and seed treatment should be done to determine the sowing and sowing methods; for the planting method, the planting method should be determined, the grass source should be selected, and the grass source should be dug and planted; laying grass blocks and laying grass rolls should go through the selection of grass sources, determination of grass blocks, grass roll size specifications, transportation and storage, laying, etc. Different laying methods have their own advantages and disadvantages. When laying the lawn, the appropriate planting method should be selected according to the actual situation to produce economical and high-quality lawns.
1. Fine land preparation
The site must be prepared according to the design elevation before planting the lawn. The main operations include: digging (planing) loose soil, leveling, fertilizing, etc., and changing the soil when necessary. For lawns with special requirements such as sports field lawns, groundwater drainage facilities should also be set up. In order to improve soil fertility, it is best to apply some high-quality organic fertilizer as base fertilizer. In order to prevent underground pests and protect the lawn tiller roots, apply appropriate amount of pesticides evenly while applying fertilizer to avoid the powder from forming lumps and affecting the survival of lawn plants.
2. Arrange drainage and irrigation system
Like other venues, lawns need to consider the removal of surface water. Therefore, when leveling the ground at the end, it is necessary to consider the drainage of the ground. There are depressions to avoid water accumulation. Lawns use gentle slopes to drain water. A gentle slope ditch is built in a certain area. At the bottom end, a rainwater outlet can be set to receive and discharge surface water, and it can be drained through underground pipes or directly connected to the lake pool by a ditch. The ideal flat lawn surface should be slightly higher in the middle and gradually tilted to the surrounding or edge. Lawns that are too flat or have too high groundwater levels or too much water accumulation, sports field lawns, etc., should all be equipped with concealed pipes or open ditches for drainage. The most complete drainage facility is to use a concealed pipe system connected to a free water surface or drainage network. At present, most lawns at home and abroad use sprinkler irrigation. For this reason, the sprinkler network should be buried before the final leveling of the site.
