The stage of restoration overgrowth refers to the stage of initial planting of grassland, planting for one year or full coverage (100% overgrown with no empty land), also called the overgrown period. According to the design and process requirements, the ground bed of the newly planted grass should be strictly removed from weed seeds, grass roots and stems, and filled with pure guest soil, scraped and compacted more than 10cm before turf can be pasted. There are two types of turf: one is full patch and the other is thin patch. Thin paste is generally 20cm×20cm, a square of turf and other areas are left blank for thin paste. There is no long maturity period for all pastes. Only the recovery period is 7~10 days. For rare pastes, 50% of the vacant land will take a certain time to grow. The maturity period of the turf pastes in spring and summer is only 1~2 months, and the maturity period of autumn pastes is only 1~2 months. Winter stickers grow slowly and take 2 to 8 months.
In the maintenance management, the emphasis is on water and fertilizer management, spring sticking to prevent stains, summer sticking to sunscreen, autumn and winter sticking to grass to prevent wind and moisturizing. Generally, spray water once in the morning and evening within 1 week after pasting the grass, and check whether the turf is compacted, and the grass roots are required to be close to the guest soil. Spray water once a day in the evening within 2 weeks after application. After 2 weeks, depending on the season and weather conditions, it usually takes 2 to 3 days to spray water, mainly moisturizing. Fertilize 1 week after planting to 3 months, fertilize once every half month, spray with 0.1%~0.3% urea solution combined with watering, thin before and thick; once a month, 667m urea 2~3kg, rainy day Use a lawnmower to cut the grass when all the grass is 8~10cm high when spreading or liquid application in clear weather. Weeds are removed as early as half a month after planting, and as late as January, weeds begin to grow. Weeds should be dug and rooted in time, and compacted after digging, so as not to affect the growth of the main grass. Newly planted grassland is generally free of pests and diseases, and does not need to be sprayed. In order to accelerate growth, 0.1% to 0.5% potassium dihydrogen phosphate can be sprayed in combination with watering in the later stage.
