Abstract


This study from the lawn adaptive method of GIS the geographic distribution of our lawn transition zone discussed; transition zone is difficult to achieve the status of the evergreen lawn by selecting the appropriate grass transition zone, located in the South Sichuan International Golf Course series of tests to study the transition zone golf course planting evergreen lawn overseeding. Reached the following conclusions: 1. Several common lawn grass adaptation GIS spatial database, the database can query the country at any point of these grass species (warm-season) suitable or not suitable (cool-season) the number of days. Adaptive information to obtain the turf grass in the region. 2. Cold, warm season turfgrasses Adaptability Division, according to the adaptability of the turfgrass divided the country into suitable areas more suitable area and the area of ??discomfort to recognized there has been relatively vague lawn zonal distribution clearly defined. 3. Lawn transitional zone geographical distribution, and draw lawn transitional zone thematic maps. Studies have shown that lawn transition zone has the following characteristics: a) the transition zone including the country's 16 provinces and some or all of the broad belt region, area about the land area of ??14.25%; b) lawn transitional to the northern boundary roughly from the southwest slash to the northeast, and the southern boundary is relatively more latitude parallel lawn transition zone is the product of the combination of horizontal zonal and vertical zones. 4. The technical details on the lawn overseeding. Show that in the transition zone with effective technical planting evergreen lawn overseeding, overseeding quality by overseeding technology portfolio decisions. The Zoysia fairways in Chengdu overseeding perennial ryegrass sown at the end of October, sowing rate 10g / m 2 (100 kg), while fertilization after emergence 10g / m ~ 2 (100kg/hm ~ 2 ) about ensuring the smooth completion of the job overseeding is feasible. 5. Overseeding the lawn of cool and warm season turfgrass competition. That the clustering pattern of overseeding lawns of cool and warm season turfgrass competition measures, overseeding lawns of cool and warm season turfgrass intense competition occurs mainly in the spring conversion period. 6. The study is the first to combine GIS technology and lawn transitional research, and the geographical distribution of the transition zone on the lawn is the first time a dedicated research the lawn divisions and lawn transition zone study proposes a new method, but also evergreen lawn in the transition zone on the construction and management provides a theoretical and technical reference.
