耐降解保水剂在播植草坪上的应用

The Application of Decomposition Resistant Water Retaining Agent to Grass-seed Sowing

采用^(60)Coγ射线辐射聚合自制的保水剂,与市售保水剂进行了抗紫外线能力的比较并用于草种播植节水试验。结果表明,辐射聚合自制的保水剂抗紫外线能力强,在保水剂吸水50倍、距离12cm的15W紫外灯照射下,经300min才失去保水能力,而市售保水剂仅90min就失去保水能力;辐射聚合自制的保水剂用于草种播植,草坪草的生长质量好,可提高土壤的含水率,减少草坪浇水次数,节约水资源及劳动力,节水率为66.6%左右。

Adopting 60CO-γ rays radiation polymerization to get water retaining agent. Then, comparing this water retaining agent with the market water retaining agent on the aspect of anti-ultraviolet ability, and using it for water-saving test during grass-seed sowing. The results showed that the anti-ultraviolet ability of the water retaining agent gotten by radiation polymerization is much stronger. Under the conditions that water retaining agent absorbing 50 times water, and 12 cm apart from 15 W of uviol lamp, the water retaining agent gotten by radiation polymerization lost water retaining capacity till 300 min, but the market water retaining agent lost their capacity in 90 min. Applying the water retaining agent gotten by radiation polymerization to grass-seed sowing can improve the water ratio of soil and reduce the watering times of grass, and the grass grow well. Therefore, this water retaining agent could save water resource and labor force, and the rate of saving water was around 66.6%.
