Study On Preliminary Characters Of9Turfgrass Species Suitable For Golf Course

In this experiment, Hunan lawn commonly Paspalum vaginatum CV.Salam、 Paspalum vaginatum CV.09-1、Paspalum vaginatum CV. Sea Spray、tifgreen328、Agrostis stoloniferacv.XN-8、Agrostis stoloniferacv.XN-9、Agrostis stoloniferacv.Penn-1、Zoysia willdcv. XN-1、Zoysia japonicacv. Lantai No.3this nine kinds of lawn grass as the research object, in accordance with standards established by the United States USGA test rootzones observed the nine kinds of turf grass in Changsha phenology and external morphology and evaluation system using motion lawn to lawn integrated traits were evaluated, the results are as follows:1phenologySix kinds of warm-season grasses are turning green in late March, where tifgreen328earliest, Paspalum vaginatum cv.salam latest; except in late April-May observed Paspalum vaginatum cv.SeaSpray, tifgreen328and Zoysia japonicacv. Lantai No.3heading and flowering and fruiting, the other five kinds of grass seed for the test no heading and flowering; in mid-November to mid-December into the withering period, which Paspalum vaginatum cv.salam earliest, Zoysia willdcv.XN-1latest. Three kinds of cool-season grasses XN-8and XN-9reviving in mid to late September, XN-8than XN-9turning green early6d, Penn-1summer all the dead, and no turning green.Press the green of the length of the order of Zoysia willdcv.XN-1(273d)> tifgreen328(272d)>Paspalum vaginatumcv. Sea Spray (271d)> Zoysia japonicacv.Lantai No.3(263d)> Paspalum vaginatum cv.09-1(256d)> Agrostis stoloniferacv.XN-8(246d)> Agrostis stoloniferacv.XN-9(242d)> Paspalum vaginatum cv.salam(233d)>Agrostis stoloniferacv.penn-1(205d). Especially the newly introduced Paspalum vaginatum cv. Sea Spray overcome the older generation Paspalum vaginatum cv.salam reviving late, early yellow, green and wintering poor short-term disadvantage, outstanding performance.2external morphologyZoysia japonicacv.Lantai No.3and Zoysia willdcv.XN-1belongs to the mid-type, and the leaf length, leaf area and plant height are Zoysia japonicacv.Lantai No.3maximum, Paspalum vaginatum cv.09-1internode thick, three varieties (lines) in general, the rest belongs to plant low, slender leaves, internodes type of moderate thickness, good performance.3BiomassAboveground biomass in the order of:Zoysia japonicacv.Lantai No.3> Zoysia willdcv.XN-1> Agrostis stoloniferacv.penn-1> Agrostis stoloniferacv.XN-9> Agrostis stoloniferacv.XN-8> Paspalum vaginatum cv. SeaSpray> Paspalum vaginatum cv.salam> Paspalum vaginatum cv.09-1> tifgreen328. Belowground biomass in the order of:Zoysia japonicacv.Lantai No.3> Zoysia willdcv.XN-1> Paspalum vaginatum cv. Sea Spray> Paspalum vaginatum cv.salam> Paspalum vaginatum cv.09-1> tifgreen328> Agrostis stoloniferacvXN-8> Agrostis stoloniferacv.penn-1> Agrostis stoloniferacv.XN-9.Zoysia willdcv.XN-1and Zoysia japonicacv.Lantai No.3high biomass, indicating that weed resistance, drought tolerance, resistance to disease and insect resistance trampling strong, creeping bentgrass based biomass low, indicating that anti-creeping bentgrass, adaptability is poor, other varieties (lines) performance center.4Turf CharacteristicsSeashore paspalum in Changsha series, in addition to density, lower scores disease, other items scores were higher; tifgreen328addition to the low intensity of the lawn, the other outstanding performance indicators; creeping bentgrass series advantage lies in its texture, uniformity outstanding performance, the disadvantage is summering poor, lawn Ping low intensity, slow turf, especially Agrostis stoloniferacv.penn-1summer basic withered, autumn can not be restored; Zoysia lawn intensity series of advantages, coverage, disease resistance, the green of outstanding performance, the disadvantage is poor texture.5integrated traits evaluatedEvaluation system by nine kinds of sports turf turfgrass comprehensive quality evaluation results are:Paspalum vaginatum cv.salam and Paspalum vaginatum cv. Sea Spray is V grade, indicating that the two varieties for golf courses and other sports Changsha lawn. Paspalum vaginatum cv.09-1, tifgreen328, Zoysia willdcv.XN-1grade Ⅳ, indicating that the four varieties (lines) in Changsha, according to the actual application, as an alternative to golf sports turf grasses. Creeping bentgrass series and Zoysia japonicacv.Lantai No.3grade Ⅲ, in Changsha show in general, not for golf sports turf. In summary, through the nine turfgrass varieties (lines) in Changsha phenology, external morphology observation and evaluation of integrated traits lawn, Changsha regions and regions with similar golf course grass chosen to provide a theoretical basis and practical reference.
