In winter, the dormant lawn is in an extremely fragile state and is easily damaged by external factors. Because it is necessary to establish lawn protection signs, strengthen personnel patrols, and strictly prevent excessive trampling by pedestrians and rolling by passing vehicles. If the above-ground part of the lawn is worn out due to trampling and rolling during the dormant period, the underground part will be frozen and die, which will affect the timely greening of the green lawn next year. After the temperature rises, some lawns will sprout and the lawn will begin to tiller. The most feared thing is trampling, and trampling should be avoided as much as possible, causing soil compaction and bald spots on the lawn.
Summarize the lawn maintenance and management, and conduct a comprehensive statistics of the labor, plant protection, fertilization, sprinkler irrigation, mowing, weeding and other work in production. Compare with the original plan to see which work has not been completed and which work needs to be improved, so as to further improve the maintenance work. On the basis of summarizing last year’s work, make an annual production plan and budget, purchase materials, pesticides, fertilizers, equipment, facilities, etc., prepare for labor, and implement this year’s technical measures. In arid areas with strong winds and sand, especially for lawns sown in the same year, water should continue to be added to freeze-proof water. At this time, the irrigation temperature is low. In order to prevent ice cover, watering should be done between 10 am and 3 pm on sunny days so that the soil can absorb it quickly. This work should be completed before the temperature drops, and water can be returned in time.
In addition to the above measures, to protect the dormant lawn, it is also necessary to apply fertilizers reasonably, prevent cold and prevent fire.
In the dormant winter, a certain amount of organic fertilizer can be added to the cold-season lawn to improve the soil structure, promote the activity of beneficial microorganisms in the soil, increase the ground temperature, enhance soil fertility, and reduce diseases. All regions should combine local climate factors, adapt to local conditions, and use them flexibly. When applying fertilizer, fertilizer should be applied evenly to avoid “spotting”; the lawn should be trimmed before fertilization, and watered immediately after fertilization to prevent burns to the lawn.
For lawns that are laid later or sown later in autumn, they can be covered with covering materials such as non-woven fabrics, plastic films, plant ash or straw to prevent cold and frost damage during the winter dormancy period. The lawns in the winter dormant period gradually enter the yellowing period, which is very prone to fire, especially in places where there are many people. In addition to doing a good job of pre-winter pruning and removing the thick grass mat layer, the dead branches and leaves on the lawn should also be cleaned up. These flammable materials are easy to cause fire.
Water is the source of life, and the lawn is no exception. In the dry season, no matter how “dejected” the green lawn looks, once the rain moistens the soil, the lawn will always come back to life, providing us with fresh air and a green mood of contact with nature.
To get a perfect lawn, you need to water it frequently, especially in the dry season or in areas with less than 1000MM of rainfall. Water needs to be added twice a week, and in the hot summer, the water requirement should be more; each watering should be able to moisten the soil layer 15CM deep.
The best time for watering is between the morning sun, because watering at noon can cause burns to the lawn, and watering the lawn in the evening is prone to disease. However, the amount of water should not be too sufficient, because when the amount of water is too sufficient and water accumulates, the roots of the lawn will be deprived of oxygen, suffocated, and rotten. At this time, the lawn drainage work must be done well. Generally, when building the root lawn, a 2% water elevation slope is adopted to achieve the purpose of drainage. Drainage can also be done by using drainage pipes or underground ditches.
