Problems solved by technology

However, in the transition zone area, due to the distinct seasons and the large annual temperature difference, there is currently no turfgrass species that can perform well in this area and is evergreen in all seasons. requirements
However, due to improper technology, various phenomena such as low emergence rate, poor seedling rate, and uneven emergence and seedling growth are often caused.

Embodiment

[0019] Experiment site 1: Guozhuang Town, Jurong City, Jiangsu Province, in the lawn base, with an area of ​​5200m 2 ; Experiment site 2: In the lawn base of Jiangsu Agriculture and Forestry Vocational and Technical College, with an area of ​​5200m 2 ; Experiment site 3: the lawn outside the guest house in Yangzhou City.

[0020] The selected lawn grass species: the warm-season grass species is Tiantang 328, and the cool-season grass species is Runcao No. 2 from Eguancao.

[0021] Operating time: as figure 1 As shown, from July 15th to 30th, 2014, the mowing height was raised by 1 to 1.5cm higher than usual, which caused the lawn cover to rise; from September 19th to October 11th, 2014, the lawn cover Low-cutting at a certain height, leaving a layer of leafless branches at the base, so that the seeds of cool-season grasses can fall smoothly to the soil surface, and reduce the amount of seeds retained in the grass layer;

[0022] Removal of grass clippings: remove all trimme...

Abstract

The invention discloses a coverage difference-layer overseeding method. According to the overseeding method, special growth properties of tifdwarf bermudagrass seeds are utilized and a unique pruning technology is adopted; in a lawn growth management process, relatively high parts are pruned to form a top green leaf coverage layer and a base part becomes a leaf-free branch layer; in an overseeding process, the top green leaf coverage layer is pruned and a leaf-free branch layer is kept, so that seeds can smoothly fall down to the ground after grass seeds of cold-season type lawns are sowed and a condition that the seeds are remained on leaf layers is reduced; the germination rate, the emergence rate and the seedling forming rate of the seeds are improved, so that the quality of the lawns is improved and the landscape quality of the lawns is improved.

Description

technical field [0001] The invention relates to an overseeding method of poor coverage layers, which belongs to the technical field of green planting. Background technique [0002] With the rapid development of urban construction and urban landscape green space construction, the requirements for the quality of lawns are getting higher and higher, especially evergreen lawns in all seasons. However, in the transition zone area, due to the distinct seasons and the large annual temperature difference, there is currently no turfgrass species that can perform well in this area and is evergreen in all seasons. requirements. However, due to improper technology, various phenomena such as low emergence rate, poor seedling rate, and uneven emergence and seedling growth are often caused. In this case, it is necessary to develop a new overseeding method based on the special growth characteristics of Tianfudao and make use of this characteristic. Contents of the invention [0003] Pu...
