Embodiment 1

[0033] 1) Over-sowing time: Over-sow grass seeds from the end of September to the beginning of October;

[0034] 2) Overseeding grass seeds: perennial ryegrass (Lolium perenne L.) commonly used varieties "Yeying", "Fairway", etc.;

[0035] 3) Overseeding amount: 20-35 g / m2;

[0036] 4) Lawn bed preparation: combing, cutting, pruning, punching, fertilizing in autumn, pest control and other operations for the warm-season lawn to be overseeded;

[0037] 5) Sowing: The best sowing effect is when there is no wind; generally use a rotary hand-push seeder to sow twice in the form of "meter" until it is uniform and mark it to prevent missing sowing. Test before sowing; Finally, use a thick blanket or mat to drag the brush along the "Z" shape to brush the seeds into the turf, but be careful not to drag the grass seeds out of the overseeding area;

[0038] 6) Sanding: Immediately after mopping, the general amount of sand used is 0.3-0.5m3 / 100㎡, and it should be mopped again after sand...

Abstract

The invention provides a warm-season lawn overseeding method and belongs to the technical field of lawns. The method includes the steps of overseeding time setting, wherein reseeding of cold-season grass seeds is conducted on a warm-season lawn from late September to early October, and the cold-season grass seed overseeding amount is 20-35 g/m<2>; preparation of a turf bed; sowing; sand laying; irrigation; rolling; pruning; fertilizer application; weeding; disease prevention; maintenance. According to the warm-season lawn overseeding method, reseeding is conducted on the warm-season lawn by means of the cold-season grass seeds, proper overseeding time and overseeding amount are selected, and the lawn is formed quickly by taking the measures of turf bed preparation, sowing, irrigation, pruning, maintenance management and the like, so a good athletic lawn is obtained while the warm-season lawn is dormant in winter; by means of water and fertilizer control, the cold-season grass and warm-season grass are successfully converted in June and July, and accordingly the lawn remains green throughout the year.

Description

technical field [0001] The invention belongs to the technical field of lawns, and in particular relates to an overseeding method for warm-season lawns. Background technique [0002] The main content of several key factors affecting the lawn formation of bermudagrass ryegrass in autumn sowing before winter in Hangzhou Bay area: Through experiments on different sowing dates and different weeding intensities, the influence of bermudagrass ryegrass in autumn on top-seeding black ryegrass in Hangzhou Bay area was studied. Wheatgrass, the main conclusions: ①Climate is the key factor affecting the lawn formation of ryegrass top-seeding in autumn, and the most suitable temperature for top-seeding ryegrass is that the average daily temperature is 18-23°C, and the time is in the first ten days of October; ②Grass grooming intensity (≥ 50), the emergence rate of ryegrass is uniform, and it can form a lawn in the first ten days of November, and the landscape effect can be guaranteed. Te...
