不同种衣剂处理对黄瓜生长及其根际微生态的影响
Effects of different coating agents on cucumber growth and the rhizosphere microecology
摘要
Abstract
To specify the application security of three seed coating agents on cucumber,the effects of three seed coating agents of Carbendazim·Thiram,Thiram·Carbofuran and Thiram·Carbofuran· Triadimenol on seeds germination, seedling growth and development and its rhizosphere soil microecology were studied by tray experiment. The results showed that all the seed coating agents affected seeds germination and seedling growth and development to different degrees.Carbendazim· Thiram and Thiram·Carbofuran had no significant influences on germination rate,germination vigor and germination index of cucumber;Thiram·Carbofuran·Triadimenol had no significant influence on the seeds germination rate,while it significantly reduced the germination vigor and germination index. The three seed coating agents influenced shoot growth and development of seedling-stage at different levels:Carbendazim·Thiram significantly reduced leaf area; Thiram·Carbofuran significantly increased plant height and stem diameter; Thiram·Carbofuran·Triadimenol significantly reduced plant height. The three seed coating agents significantly inhibited root development and activity of cucumber,compared to the control, fresh weight of roots and root activity reduced by 9. 58% to 34.90% and 46. 73% to 71. 37%,respectively. The three seed coating agents affected enzymatic activities and microbes in cucumber rhizosphere substrate.Compared to control,Thiram·Carbofuran· Triadimenol significantly reduced the activities of urease,phosphatase, and catalase in cucumber rhizosphere by 23. 56%,36. 90% and 25. 35% respectively;Thiram·Carbofuran and Thiram· Carbofuran·Triadimenol significantly reduced bacterial density of cucumber rhizosphere,while increasing fungal density.关键词
