【摘要】 2007-2008年在东莞峰景高尔夫球场设置不同修剪高度,用草坪宁71号控制光鳞水蜈蚣Kyllingabrervifolia,确定草坪修剪高度对草坪宁71号防除海滨雀稗Paspalum vaginatums中莎草效果及对海滨雀稗草坪草叶色、长势的影响。结果表明:草坪宁71号1 kg/hm2分别喷施在光鳞水蜈蚣5-7叶期,草坪修剪高度为10、15、20、25、30和35 mm,药后14 d,对光鳞水蜈蚣株防效分别为93.9%、83.4%、80.8%、74.1%、58.3%和39.7%。药后28 d,对光鳞水蜈蚣株防效分别为100%、99.5%、96.8%、94.2%、80.7%和75.5%;对光鳞水蜈蚣鲜质量防效分别为100%、99.7%、98.1%、94.1%、91.6%和90.6%。草坪宁71号1 kg/hm2对海滨雀稗草坪中的光鳞水蜈蚣的防效随修剪高度的降低而提高,以修剪高度25 mm以下为好。对草坪色泽、生长势均无不良影响。2008年在中信汕头高尔夫球会示范性试验,进一步证实,海滨雀稗草坪修剪25mm以下,用草坪宁71号防除光鳞水蜈蚣的效果达85%以上。更多还原

【Abstract】 The study was conducted to determine the effects of mowing height on Kyllinga brervifolia control with CaoPingNing 71# and leaf color,growth vigor of seashore paspalum(Paspalum vaginatum) in Dongguan Hill View Golf Club during 2007 and 2008.The results showed that applied Caopingning 71# at 1 kg/hm2 to control K.brervifolia at the mowing height of 10 mm,15 mm,20 mm,25 mm,30 mm and 35 mm at 5-7 leave stage,the control effectiveness was 93.9%,83.4%,80.8%,74.1%,58.3% and 39.7% respectively,after 14 days. 28 days after the control effectiveness was 100%,99.5%,96.8%,94.2%,80.7% and 75.5%,respectively.K.brervifolia fresh weight control effectiveness was 100%,99.7%,98.1%,94.1%,91.6% and 90.6%.The effectiveness was improved with the decreasing mowing height of seashore paspalum,and the best mowing height was below 25 mm.There was no bad effect of 1 kg/hm2 Caopingning 71# applied to different mowing height of seashore paspalum on leaf color and growth vigor.The trial demonstrated in Citic Shantou Golf Club in 2008.It was further proved that effectiveness of K.brervifolia control with CaoPingNing 71# were more than 85% in the mowing height below 25 mm for seashore paspalum.更多还原
