Abstract Even though mango productivity in Ethiopia is low due to moisture stress, there is no report on how such constraint could alleviate using Cocoon water-saving technology. Cocoon is small water reservoir technology which uses for plant growth in dry season. The objectives of this study were to introduce and evaluate effectiveness of water-saving techniques on mango seedlings survival and growth in Mihitsab-Azmati watershed, northern Ethiopia. In this experiment, five treatments of water-saving techniques with mango seedlings were evaluated. These were: Cocoon sprayed by tricel (T1), Cocoon painted by used engine oil (T2), Cocoon without tricel and oil (T3), manually irrigated seedlings (T4) and mango seedlings planted during rainy season (T5). The survival and growth performance of mango seedlings were recorded at six months and one-year after transplanting. Data on plant survival, height, number of leaves per plant, shoot length, stem diameter and crown width were subjected to analysis of variance and t-test. There were significant differences in the treatment effects on mango seedlings transplanted survival, plant height, number of leaves per plant, shoot length, stem diameter and crown width measured at six months and one-year after transplanting. The lowest survival rate (20 %) was found during both data collection time in T5. Six months after transplanting, the highest growth parameters were measured from T1 whereas the lowest was from T5. However, one-year after transplanting, the highest growth parameters were measured from T3. Plant heights increments between the two measurement periods for T3, T2, T1, T4 and T5 were 45.1, 38.5, 24.8, 9.8 and 7.0 cm, respectively; indicating that T3 performed better than the other treatments. The t-test on mean differences between the same growth parameter measured at 12 and six months after transplanting also showed significant differences. The Cocoon water-saving technology was superior in improving mango seedlings survival and growth in the study area. This study generalized that Cocoon seems promising, sustainable and highly scalable with mango seedlings at large-scale in the study area conditions. However, this technology should not be assumed to perform uniformly well in all environmental conditions and with all tree species before demonstrated on a pilot study.

节水技术对生长性能的影响 P节水技术对埃塞俄比亚北部拉玛地区 Mihitsab-Azmati 流域芒果 (Mangifera Indica L.) 幼苗生长性能的影响

摘要 尽管由于水分胁迫,埃塞俄比亚的芒果产量较低,但没有关于如何使用 Cocoon 节水技术缓解这种限制的报道。Cocoon是一种用于旱季植物生长的小型蓄水技术。本研究的目的是介绍和评估节水技术对埃塞俄比亚北部 Mihitsab-Azmati 流域芒果幼苗存活和生长的有效性。在本试验中,对芒果幼苗的五种节水技术处理进行了评价。它们是:用三氯乙烯喷洒的茧 (T1)、用旧发动机油喷洒的茧 (T2)、没有三氯乙烯和油的茧 (T3)、人工灌溉的幼苗 (T4) 和雨季种植的芒果幼苗 (T5)。在移栽后6个月和1年记录芒果幼苗的成活和生长性能。对植物存活、高度、每株叶数、枝条长度、茎直径和冠宽的数据进行方差分析和 t 检验。移栽后6个月和1年的芒果幼苗移栽成活率、株高、单株叶数、枝条长度、茎粗、冠宽等处理效果存在显着差异。在 T5 的两个数据收集时间内都发现了最低的存活率 (20%)。移植后 6 个月,最高生长参数从 T1 开始测量,而最低生长参数从 T5 开始。然而,移植一年后,最高的生长参数是从 T3 开始测量的。T3、T2、T1、T4 和 T5 的两个测量周期之间的株高增量分别为 45.1、38.5、24.8、9.8 和 7.0 cm;表明 T3 的表现优于其他治疗。在移植后 12 个月和 6 个月测量的相同生长参数之间的平均差异的 t 检验也显示出显着差异。Cocoon节水技术在提高研究区芒果幼苗成活率和生长发育方面具有优势。这项研究概括了 Cocoon 在研究区域条件下大规模种植芒果幼苗似乎是有前途的、可持续的和高度可扩展的。然而,在试点研究证明之前,不应假设该技术在所有环境条件下和所有树种下均表现良好。分别为 0 厘米;表明 T3 的表现优于其他治疗。在移植后 12 个月和 6 个月测量的相同生长参数之间的平均差异的 t 检验也显示出显着差异。Cocoon节水技术在提高研究区芒果幼苗成活率和生长发育方面具有优势。这项研究概括了 Cocoon 在研究区域条件下大规模种植芒果幼苗似乎是有前途的、可持续的和高度可扩展的。然而,在试点研究证明之前,不应假设该技术在所有环境条件下和所有树种下均表现良好。分别为 0 厘米;表明 T3 的表现优于其他治疗。在移植后 12 个月和 6 个月测量的相同生长参数之间的平均差异的 t 检验也显示出显着差异。Cocoon节水技术在提高研究区芒果幼苗成活率和生长发育方面具有优势。这项研究概括了 Cocoon 在研究区域条件下大规模种植芒果幼苗似乎是有前途的、可持续的和高度可扩展的。然而,在试点研究证明之前,不应假设该技术在所有环境条件下和所有树种下均表现良好。在移植后 12 个月和 6 个月测量的相同生长参数之间的平均差异的 t 检验也显示出显着差异。Cocoon节水技术在提高研究区芒果幼苗成活率和生长发育方面具有优势。这项研究概括了 Cocoon 在研究区域条件下大规模种植芒果幼苗似乎是有前途的、可持续的和高度可扩展的。然而,在试点研究证明之前,不应假设该技术在所有环境条件下和所有树种下均表现良好。在移植后 12 个月和 6 个月测量的相同生长参数之间的平均差异的 t 检验也显示出显着差异。Cocoon节水技术在提高研究区芒果幼苗成活率和生长发育方面具有优势。这项研究概括了 Cocoon 在研究区域条件下大规模种植芒果幼苗的前景、可持续和高度可扩展性。然而,在试点研究证明之前,不应假设该技术在所有环境条件下和所有树种下均表现良好。在研究区条件下大规模种植芒果幼苗具有可持续性和高度可扩展性。然而,在试点研究证明之前,不应假设该技术在所有环境条件下和所有树种下均表现良好。在研究区条件下大规模种植芒果幼苗具有可持续性和高度可扩展性。然而,在试点研究证明之前,不应假设该技术在所有环境条件下和所有树种下均表现良好。
