Abstract
This paper sets out to investigate 1) the impacts climate change and 2) the effects organic supplements, have on the growth performance of creeping bentgrass. The adaptability of this cool-season grass in eastern China will be examined, based on data collected from both the phytotron and the test-sites situated on-site of 4 standard golf courses in eastern China. The evaluation of the experiments is based on the observations of the characteristics and adaptabilities of 15 selected turfgrass varieties from three major U.S. seed companies put through the ''summer stress'', with specific indicators for comparison of acclimatization such as the root-length and the biomass of the chosen subjects. The adaptability of the subjects was put through a further test of their receptivity to a variety of common organic supplements.n the phytotron, the subjects were put through the simulation of the passing of a sub-tropical monsoon season typified by the symptomatic post-season spike in temperature. The performance of the organic supplements was inconclusive within the set parameters. On the other hand, the on-site experiment has produced more determinate and promising results. With discrete climatic conditions, the differences in the combinations of the temperatures and humidity of the 4 golf courses have significant and varied effects on root-length and bio-mass of these subjects and interacted heavily with the turfgrass varieties. As for the subjects’ receptivity to the organic supplements, with the sole exception of worm casts administered in isolation, there were notable effects on the overall production yield.
