摘　　要：对狗牙根草坪施用油茶饼粕有机肥,研究不同施肥处理对草坪的外观质量、抗病虫性、分蘖数、叶片养分含量、叶绿素含量以及草坪土壤效应的影响。试验结果表明,茶粕有机肥对草坪的生长具有良好的效果:明显改善了草坪的色泽和质地,提高了草坪的密度和均匀性;已脱茶皂素并已发酵的茶粕能快速增加草坪的分蘖数,未脱茶皂素的茶粕能有效地预防病虫害;茶粕有机肥的施用促进了草坪草全氮、全磷、全钾养分以及叶绿素含量的增加,改善了土壤的理化性质。30 g/m2施肥量对草坪各项生长指标的促进作用要比15 g/m2施肥量好。Camellia cake organic fertilizer was applied to turf grass Cynodon spp. Rich. to study the influence of different fertilizer treatments on the appearance quality of turf, resistance to diseases and pests, tiller number, leaf nutrient contents, chlorophyll content and soil effect to turf. The results show that Camellia cake organic fertilizer had a good biological influence on growth of turf grass Cynodon： the turf＇s color, texture, density, and uniformity have been significantly improved; the number of tillers has been quickly increased by applying Camellia cake which had been removed tea saponin and fermented, while the pests and diseases have been effectively prevented by applying Camellia cake which had not been removed tea saponin; the nutrients of total nitrogen, total phosphorus, total potassium, and chlorophyll content have been promoted, and the physical and chemical properties of soil have been improved by applying Camellia cake. The fertilization amount of 30 g/m2 had a better promotion to the growth of turf grass Cynodon than the fertilization amount of 15 g/m2.
