我国对高尔夫球场草坪管理的研究中还没有涉及果岭球速方面的研究,随着我国高尔夫运动的进一步发展,必然会更加强调草坪运动性能的提高,因此对果岭球速的整体提高和均一程度的提高将会是今后研究的焦点之一。本论文就是针对我国气候特点和我国高尔夫球场养护特点进行的果岭球速方面的研究。 论文主要应用果岭测速计(Stimpmeter),在北京万柳高尔夫球场进行果岭球速变化特点的调查和不同果岭养护措施对果岭球速影响的研究。通过对球场果岭球速的调查和对修剪、滚压、打孔、铺沙、梳草等养护措施对果岭球速影响的试验,结果表明: 万柳高尔夫球场全年的各月的平均果岭球速基本保持在一个较快的水平(230cm左右)。除8月、9月出现球速下降外,其他各月果岭球速都呈上升的趋势,最快的果岭球速出现在10月,平均球速为238.3cm。 高尔夫球场果岭球速春季比夏季和秋季较慢。春季球场果岭球速的均匀程度较差,夏季和秋季均匀度较高。主要原因是夏季和秋季较春季进行的养护措施要多,且施用频率更高,如修剪,滚压等。 修剪高度和修剪方式对果岭球速的影响均极显著。修剪后平均果岭球速显著提高,果岭球速的均匀程度也有所提高。修剪高度每降低0.5mm,果岭球速会提高近5%左右。相同修剪高度的二次修剪措施能进一步提高果岭球速, 3mm时二次修剪可以将果岭球速显著提高15.2cm。 滚压可以提高果岭球速50cm左右,滚压对果岭球速的提高可以持续两天左右。剪草高度3mm,每3天滚压一次得到的平均果岭球速最快,为281.9cm。在修剪高度相同时滚压频率越高所得到的果岭球速越高。 打孔后进行铺沙滚压的操作对果岭球速的提高最大,达到70cm。实施一周左右达到稳定,实心打孔和空心打孔没有显著差异。 梳草后的果岭球速比不梳草快2cm左右,两者的差异不显著。 经过线性回归,果岭球速与留茬高度X_1、枯草层厚度X_2和土壤表面硬度X3的回归方程为y=282.2066-6.6042x_1-8.3782x_2+20.1292x_3。但是经过统计分析可知除上述三个因子和已经消除的风力、表面湿度、坡度因子外还有对果岭球速有影响的因素存在,需要进一步分析和研究。
There were little research of green speed , with the development of golf in China, People would pay more attention to the improvement of play quality of golf course. Green speed would be a focus research aera .This thesis was green speed research base on local climate and golf course maintance characteristic. Using Stimpmeter to measure the green speed of Beijing Willow Golf Course, and make sure how much the green maintenances affect the green speed. The maintenances is about mowing , rolling, coring. The results were: The investigation of green speed in whole year show that average green speed of Willow Golf Course was fast (230cm) according to the USGA Green Speed Chart. Green speed increased on every mouth Except August and September. The greatest average green speed of the whole course was in October, and the Stimpmeter reading was 238.3 cm.. The uniform of green speed on the Willow golf course was worse in Spring. It would be better In Summer and Autumn. With the more maintains conduct the more consistent green speed was. The greatest green speed was on 9Am and after that, green speed had drop a little, then it was hold on 13pm. Mowing height and mowing type had magnificent different on affect green speed. The green speed would increase large after mowing. Mowing could increase the uniform of the green speed. Green speed would decrease 5% with the mowing height 0.5mm lower. Double cutting could enhance the green speed better than mowing. Green speed was the biggest with double cutting at 3mm mowing height. The research of 4.5mm,4mm,3.5mm mowing height show that the green speed will decrease 5% when the mowing height drop 0.5mm. Mowing can make the green speed more consistent. Double cutting could increase green speed in 10cm. There was no different with different measure direction on green. Rolling could increase green speed about 50cm. On the second day the green speed would drop 40 cm , then it was steady after the third days . the more time rolling the green the higher the green speed was. Core operation could increase green a letter , but it had not different in statistic . If the green had topdressing and rolling after core, it could make the green speed 70cm higher then without that. Grooming could increase green speed about 2cm, But it was not different in statistic.
