以狗牙根品种运动百慕大和天堂328为材料,采用双因素随机区组设计,研究施用不同浓度(0、0.4 l/hm~2、0.8 l/hm~2和1.2 l/hm~2)、不同频率(3d、6d和10d)抗倒酯对草坪草狗牙根的高度、叶长、叶宽、节间长、叶色、地上生物量、根长、地下生物量及根冠比的影响.结果表明:外施抗倒酯能降低运动百慕大和天堂328的高度、叶长、节间长,减少地上生物量;同时,提高叶色评分,增加地下生物量,提高根冠比;对两种狗牙根的叶宽和根长无显著影响.

In order to reduce the prune times, cost of management and maintenance, and provide a theoretical basis for the application of trinexapac-ethyl, two Bermudagrass (Cynodon spp.) cultivars, Tifsport and Tifgreen were used to investigate the effects of different trinexapac-ethyl concentration(0, 0.4, 0.8 and 1.2 l/hm~2)and frequency(3, 6 and 10 d)on the growth performance, biomass and root/shoot ratio by randomized plot design. The results showed that the height, leaf and internode length and aboveground biomass could be reduced by the application of the trinexapac-ethyl, at the same time, the le...
