摘要
利用泥炭基质和重迎茬土壤(CK)进行黄瓜栽培试验,测定不同基质对黄瓜株高、茎粗、根长鲜重等生长指标及对枯萎病发生情况的影响。结果表明:泥炭栽培的瓜苗在根长及株高上较对照差异显著,侧根量比对照明显增多;泥炭培养基能有效减少苗期猝倒病及枯萎病的发生;泥炭栽培的黄瓜单株产量明显高于对照;泥炭处理的黄瓜PAL、CAT、SOD酶活比同期对照高出33.05%～62.25%、12.56%～43.79%、13.09%～72.82%。说明泥炭培养基对黄瓜表现出良好的促生及抗病作用。
Used two matrix of peat matrix and common garden soil（CK） for cucumber cultivation experiment, determined different substrates cucumber on the influence of plant height, stem diameter, root growth such as fresh weight index and the influence of the blight disease resistance. The results showed that the cultivation in peat had significant difference in root length and plant height than CK, lateral root volume increased significantly than in CK; The peat medium can effectively reduce the seedling sudden fall ill and the occurrence of blight;The peat cultivation of cucumber plant yield significantly higher than those of control yield per plant;The peat processing cucumber PAL, CAT, SOD enzyme activity over the same period to high contrast, 33.05% ～ 62. 25%, 12. 56% ～ 43. 79%, 13. 09% ～ 72. 82%. It showed peat treatment expressed good growth and disease resistance than CK
