Study On Assessment Of Beijing Golf Course Turf Quality

In this experiment through monitoring regularly to the beijing golf course turf quality, the monitoring of scene and the assaying in the laboratory to the affect factors about the quality of the turf, and analysis the correlations among the factors. The results are: 1. The main influent factors of Green turf quality are: physical factors of soil, plant community factor and the use function of turf. These factors are restrict each other, physical chemistry factor of soil is basic, plant community factor and the use function of turf is external presentation of the turf quality. The cultivation of turf influence synthetical assessment of golf course turf quality.2. The formula of Green turf quality assessment is: , in this formula"A"is Calculated value,"w_i"is weight value of Influent factor,"w_i '"is weight value of consistency,"R_i"is single item appraisal end value,"R_i '"is influencing factor uniform appraisal end value. using this appraisal system carrying on the measurement to the Green turf, the result is 58. 8, lower than the criterion result, it is related to cultivate and punch and it is match with the actuality of Green turf. So, this evaluation system is very external, idiographic to the Green turf quality.3. The formula for synthetical quality evaluation of Approaches, Fairways, Tee and Bunker in golf course is B=30% B₁ +30% B₂+30% B₃ +10% B₄, in this formula"B₁"is the turf quality appraisal result of Approaches"B₂"is the turf quality appraisal result of Fairways"B₃"is the turf quality appraisal result of Tee,"B₄"is the quality appraisal result of Bunker. using this appraisal system carry to the golf course except Green. the result is 85. 3, the rank of turf quality is high, and the result is match with the appearance quality of turf and the reaction of players.4. Synthetical quality evaluation index of golf course turf: C=60% A +40% B , in this formula"C"is synthetical quality evaluation index of golf course turf,"A"is the mean of Green turf quality evaluation,"B"is the mean of turf quality evaluation of other areas on golf course. using this appraisal system carry to evaluation of the golf course turf, the result is 69. 4.5. The turf quality is tremendous influenced by the artificial lakes' water quality in golf course, water′s quality monitoring results represent: The water quality potential of hydrogen conforms to the national standards basically, but exceptional samples present strong alkalescence; There is green alga In the water, Nitrogen content exceeding the allowed standard, associated measures must be improved, We should do our best to reduce turf quality influence which brought by source.6.The management and maintaining affect the quality of turf, we should do many work to satisfy turf growth.
