Winter climate is dry, the lawn enters the rest period, if the maintenance measures are not in place, it will often cause the lawn to wither and even die in the next year, the ornamental value declines, and the ecological benefits of the lawn cannot be played as it should be. Mastering scientific winter lawn maintenance skills can extend the green period of the lawn, improve the soil, and allow the grass to recuperate.
Temperature is an important cause of yellowing of winter lawns.
The dry grass layer is a densely knotted body composed of elongated grass stems, creeping stems, roots, grass leaves, and undifferentiated branches and dry leaves. If you look up the lawn, you can see that the grass above is blue, but all below the middle is dry yellow. These layers of dry grass rise up in pieces, directly destroying the landscape and easily breeding pests and diseases.
So, what measures should be taken to maintain the lawn in winter?
Step 1: Weeding and pruning
Winter weed control can prevent the seeds of the weeds themselves from falling back into the ground and growing again, and on the other hand, prevent the weeds from seriously depleting the nutrients and water of the lawn soil in the winter. In order to take other measures as a basis, a complete removal of weeds from the lawn is required before winter arrives.
Lawn mowing can promote tillering of lawn roots while controlling dicotyledonous weed growth and reducing monocotyledonous weed competitiveness. The overall principle of lawn mowing is the 1/3 principle, that is, the mowing height should not exceed 1/3 of the height of the lawn, because the growth point of different grass species is different, so the pruning height is not the same.
Mowing the lawn should be avoided in high temperature as much as possible, and the grass leaves should be removed in time after pruning. The number of pruning is generally determined according to its own conditions and the growth of the lawn, and timely pruning is conducive to the growth of the lawn.
In winter greening, low shearing (root shear) and grass thinning can effectively remove the dry grass layer, reduce the consumption of water and nutrients, promote the germination of new leaves on the lawn, thereby prolonging its green period and achieving the purpose of greening the winter lawn.
Step 2: Punch holes, spread sand, fertilize
After the lawn is used for a period of time, due to suppression, watering and trampling, the flat bed is solid and hardened, resulting in soil compaction and reducing its ventilation and water permeability function. Lawn punching can expand the surface area of the lawn, improve the penetration capacity of the thick soil of the compacted and dry grass layer, accelerate the decomposition of the dry grass layer and organic residue of the lawn, improve the absorption of water and fertilizer by the lawn, thereby greatly improving the soil ventilation and water permeability, and promoting the development of the lawn root system.
Usually, after the lawn is punched or punched, it is accompanied by sand or soil covering, and if not, the effect of punching cannot be achieved. This operation is mainly suitable for sports fields, parks or lawns that are trampled more.
After the lawn is punched, the surface of the lawn can be smoothed by laying sand, the physical properties of the lawn topsoil can be improved, and the regeneration and growth of adventitious buds and creeping stems can be promoted. However, the specific substrate is laid depends on the soil conditions.
In addition to laying organic fertilizer on the compacted soil, river sand is appropriately added, and long-lasting organic fertilizer can be laid in the area with better soil quality, and the lawn that has never been paved with sand can be mainly paved with river sand. Proper spraying of plant hormones can regulate plant growth, so that the lawn can maintain nutritious growth in autumn and winter, and achieve the effect of green preservation in winter.
Step 3: Strengthen watering
The lawn enters the dormant period, and strengthening the watering of the lawn is one of the main measures for the maintenance of the lawn in winter. The south should continue to water according to the amount of evaporation, and the most important thing in the north is to grasp the timing of watering frozen water before freezing, and the frozen water should be watered evenly and thoroughly.
In fact, all the lawn watering, should be a full watering, to avoid only watering the topsoil, at least should reach the wet soil layer of more than 30 cm, for excessively arid lawn watering, the wet layer of the soil layer should reach more than 40.
In temperate areas, the lawn that has been trimmed, punched, and laid with an organic substrate should be watered once every 1 to 2 days when it does not rain, in order to play a green protection effect.
When fertilizing, it is necessary to pay attention to the uniformity of fertilization, so that the color of the lawn does not produce spots, and it is necessary to water after fertilization.
Step 4: Spray the turf greener
With the gradual increase in people's requirements for garden landscape effects, there are currently non-oily and completely non-toxic to plants, the environment, harmless lawn special color adder nutrients, used for the dormancy period of dry yellow lawn landscape transformation, to achieve the purpose of promoting the early return of lawn to greening, extending the green period of lawn, repairing disease patches, rich in a variety of nutrients required for lawn growth, spraying can not only greatly improve the landscape effect, but also promote lawn growth, enhance lawn resistance, so that lawn grass roots are robust, leaf thickening, leaf color thickened.
When can I use a turf greener?
Scope of use: the lawn is not green in time, the lawn is yellow in a large area during the dormancy period, the lawn is seriously degraded, the lawn disease causes baldness and yellowing, and the dead trees that cannot be replanted and replaced are dead seedlings.
How to use:
Using a piggyback sprayer, dilute the drug 40-60 times the liquid (according to the density of the lawn leaves, choose 60 times the liquid for the leaf density, and choose 40 times the liquid for the sparse leaves) and spray evenly after thoroughly stirring.
Precautions
1. Use when there is no rain or snow on a sunny day, and do not step on it for 24 hours after spraying.
2, the drug adhesion is strong, avoid spraying on cement, buildings and other items that do not need to be sprayed, such as accidentally sprayed on items that do not want to be sprayed, please wash away with water immediately.
3. Immediately after use, the sprayer, nozzle and strainer should be thoroughly cleaned.
