- 摘要:
- 在有限水分条件下，对盆栽石楠苗木的生长率和存活期、叶片和土壤水分水势动态变化进行研究。结果表明：（1）保水剂能提高土壤田间持水量10.8%～93.2%；（2）在停止供水后，有保水剂处理的土壤含水量、水势下降缓慢，保水剂用量越大，效果越好；（3）苗木叶片相对含水量、叶片水势下降延迟，苗木的生长受到抑制的时间延后，保水剂用量越大，效果越好；（4）保水剂处理延长苗木的生存期3.5～38.5d。
- Abstract:
- Under limited water condition,the study was carried out on survival time and growth efficiency of Photinia serrulata seedlings and dynamics of water content and water potential of soil and leaves in the pot experiment. The following results were obtained:(1)The hydrogel increased the full field water content by 10.8%~93.2%;(2)Water content and potential of soil with hydrogel reduced slowly and the effect increased with the increase of hydrogel content under no water supply condition;(3)Relative water content and water potential of leaves decreased slowly and the seedling growth was retarded later with the increase of hydrogel;(4)Seedlings survival time was prolonged by 3.5~38.5 d by the application of hydrogel.
