利用盆栽土培试验研究了不施肥、单施无机肥(每千克土施纯N 0.36 g,纯P 0.12 g,纯K 0.36 g,氮磷钾分别以分析纯尿素、磷酸二氢铵及氯化钾为肥源)、单施有机肥(每千克土施用腐熟鸡粪8 g,其N量等同无机肥处理)及有机+无机肥配合施用对种... 利用盆栽土培试验研究了不施肥、单施无机肥(每千克土施纯N 0.36 g,纯P 0.12 g,纯K 0.36 g,氮磷钾分别以分析纯尿素、磷酸二氢铵及氯化钾为肥源)、单施有机肥(每千克土施用腐熟鸡粪8 g,其N量等同无机肥处理)及有机+无机肥配合施用对种植在武汉地区新垦土壤上的冷季型草坪草苇状羊茅Festucaarundinaces生长状况、叶绿素含量和抗寒性的影响。结果表明,施肥处理均能促进草坪草初期生长,与不施肥处理相比,无机肥、有机肥及无机+有机肥配施在播种后25 d时叶片数分别增加86.5%,91.3%和84.7%,距播种60 d时3个施肥处理的分蘖数分别是不施肥处理的4.86,3.41和6.03倍。无机肥施用对越冬期草坪草叶绿素含量和提高抗寒性的效果明显好于有机肥及不施肥处理,在播种100 d时单施无机肥处理的叶绿素分别比单施有机肥和不施肥处理高24.3和42.5个SPAD值;脯氨酸(Pro)高出4.69和4.33倍,丙二醛(MDA)分别是单施有机肥和不施肥处理的51.6%和31.3%,电解质渗透率分别是后2个处理的15.3%和19.2%。在所有施肥处理中,无机、有机肥配施对草坪草生长效果最好,但在对抗寒性的影响上该处理与单施无机肥处理无明显差异。试验结果还表明,不施肥处理生长状况极差,越冬后土地裸露严重。说明合理施肥是提高武汉地区草坪草成坪质量及抵抗冬季低温胁迫的重要措施。 展开更多

[Objective]The aim of this study was to explore the feasibility of three kinds of urea formaldehyde foam substrate in tall fescue establishment as well as to study on evaluation of turf quality.[Method]The visual estimates,ecological quality estimates and utility quality estimates were used as the 1st level indicators,and the density,color,texture,uniformity,green period,cover degree,biomass,emergence energy,growth rate and turf-forming time were used as the corresponding 2nd level indicators.With T.L.Satty's method Analytic Hierarchy Process(AHP) and the fuzzy synthesis evaluation method,the weight ratio of matrix was obtained and the synthetic evaluation result was accorded with facts,then it could be regarded as the satisfying value of weight.[Result]The quality of three covering soil treatments was better than that of uncovering treatment and conventional treatment,the quality synthetic evaluation of F1 was the best,which was about 0.770.[Conclusion]Urea formaldehyde foam substrate showed high quality for turf establishment,which could be further spread and applied. 展开更多
