Most lawns in the northern regions are cold-season varieties, and they have dormant habits in the summer, especially in the early-maturing pods. During this period, the physiological metabolism of the lawn is very slow, and the resistance is also weak. If the conservation management is not strengthened, it will easily cause alopecia areata and even a large area of ​​death, which will seriously affect the landscape effect of the lawn.

The pruning of the cool-season turf is reasonable during the dormancy period in summer, and the growth is slow, and the number of pruning is relatively reduced.
1. Pruning can not be too frequent Generally trimmed two or three weeks, not too frequent. Otherwise, it will have an adverse effect on the development of the growth point of the base, and may also cause degradation of the lawn.
2. Grasp the appropriate height should be strictly in accordance with "one-third" pruning principle, that is, cut off part of the original lawn can not exceed one-third of the height. Raise the height of the lawn under the shade of forest and shading.
3. Avoid repeating the trimming of the flat bed or the relatively blunt blade of the lawn mower to avoid repeated pruning at the same location and in the same direction.
Loose soil and rolled soil and rolling are contradictory and uniform. Loose soil is to increase the permeability of the lawn, which is conducive to the absorption of moisture and nutrients from the lawn. Rolling is to increase the turfgrass and promote the growth of turf litter, so that the lawn becomes dense and robust. The combination of the two will not only ensure the healthy growth of the lawn, inhibit the growth of weeds, but also maintain the beauty of the lawn.
1. Loose soil, pruning the surface loose soil vertically, that is, mechanically remove the cover of the turf surface and loosen the soil. Vertical pruning cuts the turf and increases the air permeability of the lawn. These two measures are generally conducted in late summer and early autumn.
2. Drilling Hole punching is usually performed in the early summer. It is best to drill hollow holes with a pitch of 15 cm to 20 cm, pull out the soil column, and then backfill the rough sand.
3. Rolling is generally not carried out alone. It is advisable to combine the pruning with a roller of about 200 kg.
Water and drainage The water consumption of the lawn is reflected in several aspects such as surface evaporation, leaf transpiration, and large voids in the soil.
1. Watering time The best time for watering at sunrise, but also in the evening when the evening, but at this time watering is easy to infect diseases, with the fungicide spray. Do not water at high temperatures at noon, otherwise it is easy to cause burning and infection, it is difficult to remedy.
2. Increase the amount of watering, reduce the number of watering In order to avoid the growth of bacteria in a humid environment, accelerate the breeding, each watering must make the soil moist to a depth of 15 cm. Usually two or three times a week watering, especially in arid areas to increase the number of appropriate.
3. The slope of the timely draining bed (generally 2%) should be able to meet the requirements of drainage. If there is accumulated water in some areas, it should be drained manually or drained.
Fertilization and spraying should be prohibited during hot summer days. However, if the lawn is seriously deprived of fertilizer, 0.5% urea and 0.5% potassium dihydrogen phosphate solution can be topdressed. Once every two weeks, fertilization can be carried out simultaneously with the fight. The spray must be sprayed evenly, and the preparation concentration should not be too large. It is not allowed to mix various pesticides at will. A variety of insecticides and fungicides are used interchangeably.
