黄瓜嫁接苗快速生根技术研究

Research on Rapid Rooting Technology in Grafted Cucumber Seedlings

以黄瓜嫁接苗根系为研究对象,分别采用土培法和雾培法对其进行生根,对比分析了嫁接苗初生根时间、根长、根体积、根系数量、根重、根系活力、伤流液体积。结果表明:与土培生根法相比,采用雾培法生根黄瓜嫁接苗根系生长发育提前2d,生根率提高3.78%,根系活力提高31%,根长、根数量、根体积、根干重分别是土培生根法的1.44、1.49、2.38、1.72倍,伤流液体积是土培生根法的1.52倍,因此与土培生根法相比,采用雾培生根法黄瓜嫁接苗根系生长更早,根系活力更强,根系生长更快速,更有利于黄瓜嫁接苗的生长发育。

Treating grafted cucumber seedlings＇ root system as research object,soil culture and fog culture methods were conducted to treat root.Comparing and analyzing the time of grafted seedlings＇ primary roots,root length,root volume,root number,root weight,root vigor and bleeding sap volume.The results showed that compared with soil culture rooting method,using fog culture method,the growth of grafted cucumber seedlings was advanced 2days,the rooting rate increased 3.78%,the root vigor increased 31%,the root length,root number,root volume and root weight respectively were 1.44,1.49,2.38 and 1.72 times of soil culture method,the bleeding sap volume was 1.52 times of soil culture method.Therefore,compared with soil culture rooting method,using fog culture rooting method the grafted cucumber seedlings＇ root grew earlier,the root vigor was more powerful,the root grew more rapidly,all these were more conductive to grafted cucumber seedlings＇ growth and development.
