Bermuda lawns are warm-season lawns, and cold-season lawns must be planted in spring to deal with the dormant weather of warm-season lawns in winter, so that Bermuda lawns also have excellent lawns in winter. Bermuda lawns or lawns planted with green grass will slowly fade when exposed to frost or when the weather is lower than 10°C, and there will be a longer yellowing period in winter; while turf-type ryegrass or Poa pratensis sprout quickly. The quality of the slab is excellent, and it can be cultivated in 28-45 days in spring.
The farming time of Bermuda ryegrass mixed turf: Eastern China and Central China usually start in mid-October, and South China usually start in early November.
Preparation of Bermuda ryegrass mixed seeding turf before seeding: In order to make ryegrass emerge smoothly, the fertilizer and water consumption of Bermuda lawns should be appropriately reduced two months before the seeding, and the competition between Bermuda lawns and ryegrass during the seeding should be reduced, and the topsoil should be contacted. Reduce the thickness of the withered grass layer. Before the sowing, the Bermuda lawn should be cut low and the withered grass layer should be removed to facilitate the full contact of the grass and the soil.
Variety selection and cultivation amount of Bermuda ryegrass mixed turf: Select the fine varieties of annual ryegrass, perennial ryegrass, bluegrass and creeping bentgrass, etc., and choose different cultivation according to the different application areas of the turf. quantity. Cultivation of Bermuda ryegrass mixed turf:
A tillage machine should be used for farming to ensure the average degree of farming. After farming, it is quietly suppressed, or the sand layer of less than 15px is covered, so that the grass seeds and the soil are fully touched. The ryegrass can produce full seedlings in 7-10 days, and show beautiful green in about 21 days. It is estimated that it can be used unlimitedly after 28 days.
Sprinkler irrigation of Bermuda ryegrass mixed turf: Use a stable and moderate sprinkler irrigation system to maintain the humidity of the bed during the budding period. As the temperature begins to drop during spring sowing, large amounts of water should not be sprinkled, otherwise the wheat seedlings will be damaged. In the future, gradually reduce the frequency of sprinkler irrigation to facilitate the development of the lawn root system and form a tough and beautiful lawn.
Fertilizer for Bermuda ryegrass mixed sowing lawn: When the ryegrass grows to 2-4 leaves, apply a compound fertilizer of 3:1:2 nitrogen, phosphorus and potassium to prevent the appropriate amount of nitrogen from being applied, otherwise the disease resistance of the wheat seedlings can be reduced or burns. ; Then apply fertilizer every two weeks, preferably nitrogen fertilizer; 10-12 weeks after sowing, iron fertilizer can be applied to keep the lawn green.
