Green grass, as the name suggests, is the lawn used in the green area of golf courses. In reality, people call dwarf Bermuda sandpei commonly known as green grass. This species belongs to the genus Graminea, which is the common bermudagrass and the African bermudagrass. A hybrid variety. It has slender leaves, dense leaves, short internodes, low height, tolerance to salt and alkali, and resistance to low pruning (3-5mm). It has many advantages such as wide adaptability, strong growth potential, and rapid growth. It is the most popular in the south. One of the best golf green grasses. In recent years, green grass has also been gradually used in public green spaces, sports fields and high-end residential areas. Since the green grass is cultivated in the planting layer of Huangshajia improver, the entire lawn Mechanical drafting is used to form a lawn roll with uniform thickness and dense root growth. The laid lawn has an immediate effect and is extremely neat and beautiful. After the lawn is established, the incidence of pests, diseases and weeds is low, making it easy to manage and maintain. For the purpose of landscape effect in winter, it is often from mid-October to Perennial ryegrass was reseeded in mid-November. The green grass lawn that has been reseeded with ryegrass is loved by people for its bright green color, vigorous growth, full of vitality and good landscape effect in winter. After reseeding , making the lawn evergreen all year round.We are deeply aware of the importance of maintenance and management. If we are not careful, it will produce negative effects such as inverted spots, bald spots, and yellowing. Especially from March to June, maintenance is the top priority. The following is a brief introduction to the green grass (replenishment). The main points of year-round maintenance and management (sown with ryegrass) are:
January: Putting green grass is dormant. Apply compound fertilizer or organic fertilizer to lawns that are sown with ryegrass in early autumn, irrigate them appropriately, mow the lawn in time, and leave the grass at a height of 3 to 4 cm. To prevent the germination of weed seeds in spring, focus on spraying Apply pre-emergent herbicides. Suppress weed growth by mowing, supplemented by herbicides or pulling out by hand.
February: Putting green grass is dormant. The green grass that has been reseeded with ryegrass should be cut in time. From the second half of the year, keep low pruning, leaving the grass height 3-4cm. From the second half of the year, control water and fertilizer, stop fertilizing, and water less or not at all. Weeds can be removed with herbicides or manually, and pests and diseases are less likely to occur due to low temperatures.
March: The stolon node buds of the green grass have begun to sprout at the beginning of this month. Reseed the ryegrass and mow the grass in time. Keep the mowing low, leaving the grass height 2cm, and continue to control water and fertilizer. While mowing, you can use 10% aqueous solution. Dilute glyphosate 2000 times or spray ryegrass with paclobutrazol mixed with water to inhibit its growth. This stage is the most critical, because the dormant buds of dwarf Bermuda begin to sprout around March 10, sprout, grow new leaves, and close to It grows creeping on the ground. Ryegrass grows very fast, and both compete for water, light and nutrients. This growth method determines that the green grass is at a disadvantage. If left to its own devices, the green grass will not be able to turn green smoothly. Therefore, it is advisable to Frequent low-level mowing and the use of herbicides and chlormequat are used to inhibit the growth of ryegrass. At the same time, the lawn should be drilled(Recommended by customers Kashin Turf Aerator), combed, and part of the ryegrass, dead, and overly dense green grass stems should be combed out to increase the breathability of the roots of the lawn, promotes root growth and is conducive to the greening of green grass. At this stage, the lawn is susceptible to spring dead spot disease. Pay attention to prevention. Keep spraying with a mixture of mancozeb thiophanate methyl for 7-10 days, 2-3 times in a row , can be prevented and treated.
April: Warm-season lawns will completely turn green by the end of this month. Therefore, lawns reseeded with perennial ryegrass should be kept low-cut, leaving 1cm of grass, additional compound fertilizers should be applied, and timely watering should be done.
May: Trim the grass in time, leave 2-3cm of grass, apply compound fertilizer once in the middle of the year, and water at the right time. Weeds are reduced through a combination of low pruning and manual pulling, which is a period when pests and diseases are less likely to occur.
June: Lawn growth enters its peak period, mow the grass in time, leave 2-3cm of grass, add compound fertilizer once in the middle of the year, and water at the right time. Weeds enter the vigorous growth period, and herbicides and manual pulling can be used to remove broadleaf weed seedlings. , control with herbicides. Frequent low-level mowing can also cut off some weeds. At this stage, there is a lot of rain, high temperature and humidity, and the lawn is susceptible to rust, fusarium, fusarium wilt, downy mildew, etc. Pay attention to observation and timely prevention and control , you can take preventive measures according to the weather forecast and spray fungicides every 7-10 days.
July: The peak growth period. The ryegrass will die completely. Cut the grass in time, leaving 2-3cm of grass. Apply an additional compound fertilizer in the first ten days of the month to control moisture when it is dry and wet. At the end of early July, when the yellow plum season ends and enters the high season, water it. It should be done in the morning and evening, and fungicide should be sprayed again in the early ten days to prevent diseases.
August: The growth peak continues, so mow the grass in time. At the same time, it is advisable to comb the grass to remove part of the grass stems and hay layer to facilitate the rejuvenation of the lawn. Weeds are mainly pulled out by hand and watered in time. This stage enters the period of high incidence of insect pests. Leaf-eating pests are the most common, including Spodoptera litura, rice leaf-cutting borer, leafhoppers, etc. Underground pests include grubs, mole crickets, cutworms, etc. When pests are discovered, use pesticides promptly to control the insect population density to a minimum.
September: Growth peak. Mow the grass, water and fertilize in time. To prevent rust and powdery mildew, it is advisable to spray fungicides 1-2 times. Pay close attention to the occurrence of insect pests and prevent and control them in time.
October: The lawn is growing vigorously. Cut the grass in time to 2-3cm, and resow ryegrass around the middle of the year. Sow seeds at this time. After more than a month of growth, the young ryegrass will coincide with the green period of Bermuda. Sowing The best dosage is 20-25g/square meter.
November: The growth of Bermuda enters a slow period. The reseeded ryegrass should be re-applied with organic fertilizer or compound fertilizer in the second half of the year to maintain a good green effect in winter. If the reseeded ryegrass has poor emergence, it is advisable to replenish it in the first ten days of the year to avoid insect pests at this stage. There are still 1-2 generations to occur, so pay close attention and take timely control if found to reduce over wintering pests.
December: Bermuda enters the dormant period and ryegrass enters the growing period. Winter management should be strengthened, grass should be cut in time, and 3-4crn of grass should be left. At this stage, there are fewer weeds, diseases and insect pests, and management is simple and extensive. In summary, as long as Focus on the two stages of Bermuda’s greening period from late March to late April and the germination period of ryegrass reseeding from early October to mid-November. Together with regular lawn maintenance, the lawn can be evergreen and achieve a relatively high level. Good landscape effect.
