Methods of maintenance of winter lawns

1. Pour frozen water

Strictly grasp the watering time of frozen water, although the temperature drops after the beginning of winter, frost appears, but the turfgrass is still growing, and the soil temperature drops still needs a process, at this time, if the frozen water soil can not be frozen, the water will soon evaporate, so it will not play the role of freezing water. The best time to water frozen water should be mastered when the night freezes and the day disappears, i.e.; Watering during the day and forming a thin layer of ice at night, it can melt again the next day.

2. Hydrate in winter

The maximum temperature during the day is around 5, and if the lawn is severely deprived of water, it can also be watered from 10 am to 3 pm.

3. Cold and fire prevention

According to the temperature, straw mats, or insulation cotton are appropriately covered, or when the average daily temperature is between 5 and 10, spray "Qilin anti-frost".

As the temperature drops in winter, the lawn begins to dormant and enters the yellowing period one after another, which is very prone to fires, especially in places with frequent human activities. In addition to proper pruning before wintering and removing overly thick grass bedding, it is also necessary to regularly clean up the lawn of dead branches and leaves.

4. Anti-trampling and disease-proof

The winter lawn is in the dormant stage, and the dormant lawn is in an extremely fragile state and is very vulnerable to external damage, so the winter maintenance management should prevent excessive trampling by pedestrians and the crushing of vehicles, otherwise it will affect the rejuvenating rate of the next year.

The disease prevention and control of lawns in winter cannot be compared with summer, but it cannot be ignored, and lawns are also prone to low temperature diseases during the period of -4 to 4, so quarantine should be strengthened in time. According to the environmental conditions, spray the special fungicide "Qilin Junqing" for disease prevention and control in an appropriate and appropriate manner.

5. Return to green water in early spring

After a winter of water evaporation, the soil is relatively dry, and watering the lawn before it turns green can return to green early and prolong the green period of the lawn. When the average temperature of the day is stable above 2 to 5, you can pour water all over the water, "the night freezes and the day disappears, and the watering is just right". When irrigating, a small amount should be advisable, pay attention to watering evenly and thoroughly, and ensure that the moistened soil layer reaches 10 cm to 15 cm.

Cool-season lawn: Warm-season lawn such as grass, tall fescue, ryegrass, shears, purple fescue: Manila, knotweed, bison grass, dogtooth root, white clover, horseshoe gold and other cool-season lawns are mostly similar to winter wheat, and the winter can generally ensure a relatively long green period Warm-season lawn withers yellow in winter from the aspect of landscape effect:

Generally, there are more cool-season lawns in the north and warm-season lawns in the south.

Cut it short and water it properly. Don't overdo it and it should be watered at noon.
