耐降解保水剂在黄蝉上的节水栽培研究

Water-saving Research of Allemanda neriifolia with Water Retaining Agent of Weathering Degradation

采用60COγ射线辐射聚合得到保水剂,将该保水剂与市面保水剂进行抗紫外线能力的对比,并用于黄蝉节水试验。结果表明：辐射聚合得到的保水剂抗紫外线能力强,在保水剂吸水50、100倍,距离12 cm的15 W紫外灯辐射下,辐射聚合得到的保水剂300 min才失去保水能力,而市面保水剂在90 min就失去保水能力;辐射聚合得到的保水剂用于黄蝉盆栽节水栽培,黄蝉生长情况好,可减少浇水量,节水率在50.0%-63.9%之间。

The water retaining agent adopted by 60COγ rays radiation polymerization was compared with the market one on the aspect of antiultraviolet ability and in water-saving test of Allemanda neriifolia.It turned out that the anti-ultraviolet ability of the water retaining agent by radiation polymerization was much stronger.Under the condition of 50 times and 100 times absorping,12 Centimeter apart from 15 Watt uviol lamp,the water retaining agent by radiation polymerization losed water capacity untill 300 minutes,but the market one in only 90 minutes.Using the water retaining agent by radiation polymerizaion in water-saving culture could improve the water ratio of soil,reduce the times of watering,made the Allemanda neriifolia high quality,save the water resource,and the rates of saving water got 50.0%～63.9%.
