摘要
施用N、K、Ca和杀真菌剂对高羊茅 (FestucaarundinecesSchreb .cv .Pixie)越夏影响的研究结果表明 ,施氮肥可以打破高羊茅的夏季休眠 ,促进植株生长 ,促进植株对N、K的吸收 ,增加植株叶绿素含量 ,提高草坪质量 ,而不会明显降低草坪草的抗热性。但施氮肥后褐斑病等病害加重 。
Nitrogen, potassium, calcium and fungicide were used to study the effects of oversummer on tall fescue (\%Festuca arundineces \%Schreb. cv. Pixie). The results suggested that nitrogen could break the summer dormancy of tall fescue, enhance its growth, increase uptake of N and K, increase the content of chlorophyll, accordingly improve turf quality, without significantly decreasing heat tolerance. However, nitrogen aggravated the occurrence of brown patch. Through spraying fungicide, this occurrence could be controlled.
