How to carry out lawn greening and maintenance management

1. Generally speaking, if the turf is newly planted in that year, it should be watered 2-3 times a week (except in rainy season). When watering, the amount of water should be sufficient and the water should penetrate into the ground 10- 15cm.

2, more than two years, and the lawn grows normally, in its growing season should be watered 2-3 times (once a month).

3. In summer or when the temperature is high, watering should be done before 10 in the morning and after 4 pm.

4. When watering with a water truck, you should not only water it 1 time, but also spray it back and forth for more than 3 times.

Second, fertilization.

1, fertilization during dormancy

(1) Fertilization time: Generally, fertilization can be carried out in the dormant period from late autumn to early spring.

(2) Fertilization: Just apply the screened compost.

(3) Fertilization method: firstly, the grass leaves are cut off, and then the fertilizer is evenly spread on the lawn surface (the low-lying areas are leveled with fertilizer); The dosage per mu is generally 1 000-1500kg (every 1-2 years1time), and the fertilizer should be soaked by spraying water in time after fertilization.

2. Fertilization in growing period

(1) Fertilization time: generally from April to September.

(2) Use fertilizer: ordinary fertilizer (such as urea) is enough.

(3) Fertilization method: spray 0.5% urea solution (1 times) on the leaves, or spray urea solution on the lawn with the ratio of fertilizer to clean water of 1: 50, and water it in time after spraying, so that the fertilizer can penetrate into the soil evenly.

(4) Precautions: It takes 1 week to apply chemical fertilizer to the mowed lawn.

Third, weeding.

Weeds should be removed in time, generally on the principle of early removal, small removal and removal.

Fourth, loosen the soil

The soil in the lawn is easy to harden, so it must be loosened frequently. Usually a small lawn can be loosened with a rake. When loosening soil, you only need to dig evenly in both vertical and horizontal directions (depth is 4-8 cm, loosening soil every half month 1 time).

Verb (abbreviation for verb) rotates.

1, the rolling time is generally suitable in spring and rainy season.

2. The rolling frequency is generally 3-4 times (every year). When rolling in spring, the lawn must be watered first, so that the grass stems can be closely combined with the soil.

Six, mowing the grass

1. Mowing can generally be carried out from May to September, with mowing every 15-20 days 1 time.

2. When the height of grass exceeds 10- 15cm, it should be trimmed in time.

3. After pruning, keep the height of the grass at about 4-5 cm, and don't cut it under the same root.

Seven. Renewal and rejuvenation of lawn

1. Root cutting method: In early summer, roll the lawn with hob or roller with nails (the appropriate depth is 10 cm, the appropriate hob spacing is 20 cm, and the appropriate roller nail spacing is 5 cm), so as to cut off the old roots and apply fertilizer immediately after root cutting to promote the growth of new roots.

2. One-time regeneration method: dig out all the aged turf, then pick out weeds and tear the turf into small bundles, and finally replant the turf by point planting method (this method is suitable for grass seeds with strong germination, such as Sijiqing).

3. Strip regeneration method: dig an area for the aged turf (dig an area every 30cm), 1-2 years later, dig another area when the place to be dug is full of new grass, and complete the regeneration after 2-4 years; This method is suitable for lawns with creeping stems and large areas, such as Zoysia japonica.
