摘要
针对园艺基质草炭的斥水性,结合国外专利技术,研究了国外常用湿润剂分析纯OP-10(壬基酚聚氧乙烯醚)、工业用OP-10和分析纯聚山梨醇酯80的施用对斥水性基质草炭的湿润时间与渗透率的影响。结果表明:3种湿润剂均能很好的增强草炭的可湿润性,其中分析纯OP-10的效果最好,其次是工业用OP-10,SP的效果最差。渗透速率试验结果表明:工业用OP-10的添加能够显著提高草炭的渗透速率,同时还能够提高灌溉效率,其中2%浓度即可达到最佳效果。综合考虑效果与成本,认为工业用OP-10的应用前景最好。
This experiment was conducted to study effects of applying three different wetting agents on the infiltration rate and wetting time of water-repellent substrate-peat. After application of three infiltration agents-Analytical Nonylphenol polyoxyethylene ethers （OP-10）, OP-10 for industry use and Analytical PolysorbateS0（SP）, the results showed that all the three wetting agents improved wetness of peat, in which OP-10 got best results, and SP worked most weakly. Taking into account the costs, OP-10 for industry use have a brighter prospect, which not only increased the infiltration rate but also enhanced irrigation efficiency, and concentration 2 % received best results comparing with other treatments.
