新型有机发泡基质块培对微型月季扦插成活率及叶片光合特性影响

Effect of New Organic Sponge Growing Media Block on Cutting Survival Rate and Photosynthetic Physiological Characteristics of Rosa hybrida

以3种基质材料制成的新型模制有机发泡基质块为试材,并与未加工成型的3种原料基质进行对比,采用扦插繁育方法,研究了新型基质块对3种微型月季扦插成活率和植株叶片光合特性的影响。结果表明:3种模制有机发泡基质块(A1、A2、A3)及进口专用无土栽培基质原材(A5)与未加工成型的国产草炭和有机废弃物基质(A4、A6)之间对3种微型月季扦插成活率和叶片光合特性的影响都达到1%极显著差异水平;2种新型基质(A1、A3)对3种微型月季的互作效应达到1%极显著差异水平,品种B1"维克多"月季在新型发泡基质块A1、A3基质培的扦插成活率比未加工原料A4、A6分别提高了(A1B1>A4B1)42.73%、(A3B1>A6B1)98.27%,品种B2"吉吉"月季分别提高了(A1B2>A4B2)80.03%、(A3B2>A6B2)107.38%;品种B3"米酷"月季分别提高了(A1B3>A4B3)39.68%、(A3B3>A6B3)123.58%。基质块之间A1、A2、A3差异不显著,3种基质块与未加工的进口专用基质A5之间对扦插成活率和叶片光合生理特性的影响差异也不显著,说明用废弃物和国产草炭加工成型的新型基质块质量已达到了进口专用基质水平;3种微型月季品种之间扦插成活率和叶片光合生理特性也存在显著差异,均表现为B1("维克多")、B2("吉吉")>B3("米酷")。

The new molded organic sponge matrix block applications made three kinds of raw materials cuttage,three kinds of Rosa hybrida were used to study its impact on the survival rate of photosynthetic productivity and plant leaf cuttings,and with three kinds of raw material molding to do comparison.The results showed that between three kinds of molded organic sponge matrix blocks（A1,A2,A3）and imported raw materials dedicated soilless growing media（A5）and unprocessed shaping domestic peat and organic waste matrix（A4,A6）impact on the three kinds of Rosa hybridacuttings survival rate and leaf photosynthetic characteristics reached 1%significant difference level;two kinds of substrates（A1,A3）for three kinds of miniature rose interaction effect at 1%significance level,species B1‘Victor＇in the new sponge matrix blocks A1,A3 media culture cutting survival rate than unprocessed raw A4,A6 were increased（A1BI〉A4B1）42.73%,（A3B1〉A6B1）98.27%,B2variety‘Gigi＇were increased（A1B2〉A4B2）80.03%,（A3B2〉A6B2）107.37%;B3species‘Miku＇were increased（A1B3〉A4B3）39.68%,（A3B3〉A6B3）,123.58%.Between matrix blocks A1,A2,A3 difference was not significant,the impact of the difference between the three kinds of matrix blocks and imported special matrix A5 unprocessed cutting survival rate of leaf photosynthesis rate and physiological characteristics were not significant,indicating that use of waste and domestic new sponge matrix block peat processing quality reached the level of imported special matrix;cutting survival rate and leaf photosynthetic physiological characteristics also existed between the three kinds of miniature rose varieties,significant differences were expressed as B1（‘Victor＇）,B2（‘Gigi＇）B3（‘Miku＇）.
