Types and functions of garden coverage
Garden coverage refers to a general name that is used to improve ground coverage and soil surface protection. It is mainly divided into two types: inorganic coverage and organic coverage.
Inorganic coverage is not easy to rot, and the maintenance cost is low, but the soil ventilation is worse, affecting plant growth. The types of inorganic coverage include stones, gravel, pebbles, burned pottery and volcanic rocks, etc.
Organic coverage mainly uses pine needles, straw, wood chips, crushed branches, bark, fruit shells and other plant materials to crush, covering the flower bed, flower pots, trees and shrubs and flowers.
Next, let's take a look at the coverage of both water -saving and moisturizing effects.
Broken bark. It is a kind of ordinary and cheap coverage. There are many materials, such as a variety of pine and cypress, which are particularly suitable for slope planting. It is not easy to slide slopes. It can be purchased from the wood factories and used it.
Dry leaves. It can be kept in autumn and winter, because the deciduous decomposition is fast, and it can be crushed and covered on the soil before using them.
Grass. Free cover. The grass can also be quickly decomposed and can be converted into the nutrients of the soil. It is best to use it on a thin layer. Generally, it is necessary to wait until the grass is dry to avoid rot.
Stalk. The speed of straw decomposition is slower than the leaves and grass, and it has beautiful colors, but ensure that there is no weed in straw, otherwise it may cause weeds to grow.
Pine needles. Pine needles are beautiful covers. It can be covered in one place stably and can be degraded slowly, but using pine needles for a long time, soil will become acidic. For plants that like acidic soil, it is a very ideal coverage.
Block -shaped bark. Pine bark degradation is also very slow, but it is not easy to maintain stability, so it is not suitable for places that are used in slope or are easily rushed off by heavy rain. The size of the block can be selected by itself. The larger the degradation, the slower.
Wood chips. This can be obtained from nearby wooden factories. Such covers can quickly absorb nutrients in the soil and change the pH value of the soil.
Fruit shell (Cocoa bean shell). It is one of the most beautiful covers. Because the fruit shell has beautiful shapes and rich colors, there are many gardens like coffee coffee aroma.
Crusted gravel and river pebble. Because it is inorganic, this type of coverage will not be dismissed. Therefore, no need to consider each year. Once used, it is difficult to change.
In addition to moisturizing, each cover can also prevent weeds. Compared to the exposed soil, these natural coverage have decorative effects, which can make the garden more perfect.
