Warm-season lawn overseeding method

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.

Problems solved by technology

Technical disadvantages of this method: ①The method is not systematic, and the actual operability of overseeding is poor; ②There is no sowing amount and preparation measures for lawn beds; ③There is no sowing method and post-sowing maintenance and management measures; ④There is no specific method of pruning and weed removal and disease control Specific measures; ⑤ Key technologies for transforming seasonal grasses lacking cold and warm seasons

Disadvantages of this technology: (1) The scope of application is small, aimed at Shanghai; (2) Dwarf Bermuda lawns are followed by cool-season ryegrass; ①There is no specific variety and seeding rate of ryegrass; ②The steps of lawn bed preparation are not specific (3) No specific sowing method; (4) No specific maintenance measures after sowing, such as: ① sand filling, ② watering, ③ rolling, ④ pruning, ⑤ fertilizing; Keys to Success—No Specific Measures for Conversion Jobs

Disadvantages of this technology: (1) It is based on research results in Guangzhou; (2) There is no systematic cover sowing method, and the operability is poor; (3) There are no key technologies for cover sowing, such as bed preparation, sowing methods, watering, rolling, and pruning; Disease prevention and weed prevention; (4) No key technology - specific measures for switching between cold and warm seasonal grasses
