在试验中吸水剂使用的比例范围内,侧柏用吸水剂造林的效果一般比油松的效果好.在吸水剂使用比例相同,保蓄水分数量大体相同的情况下,年龄较小的苗木蒸腾耗水少,有利于延长存活日数而得以成活.出圃的裸根苗失水迅速,根系失水更快.以吸水剂水凝胶沾根可以延缓苗木失水进程,较长时间保持生活力.在北京地区春季的气候条件下,沾根的苗木在8h以内栽植完毕为宜.在雨季直接把吸水剂施入植穴,保蓄的水分较少,虽可提高成活率,但效果较用泥团裹根或裸根补水栽植的效果差.
In the proportion of the water-absorbing agent used in the experiment, the effect of afforestation by the water-absorbing agent of oriental arborvitae is generally better than that of the pine oil.In the case of using the same proportion of the water-absorbing agent and having the same amount of stored water, the younger seedling Transpiration water consumption is small, is conducive to prolonging the survival time and survived.Pen nude root seedlings quickly dehydration, root loss of water faster.Water absorbent hydrogel roots can delay the process of seedling water loss, a long time to maintain viability. In the spring climate in Beijing, the rooting seedlings planted within 8h is appropriate.In the rainy season directly to the water-absorbing agent into the hole, save less water, although can improve the survival rate, but the effect than with mud Wrapping or bare root hydration planting effect is poor.
