试验于2011年和2012年两季开展,选择种植在埃及伊斯梅利亚省私人果园有10年树龄的‘卡拉玛塔’橄榄树为试验材料,调查了坐果初期叶面喷施不同浓度(0.125%、0.25%和0.5%)的腐植酸肥Actosol?(含20%腐植酸+氮磷钾1∶5∶6)对橄榄树的影响;并对橄榄树的产量和果实质量(包括平均果实体积大小、重量、长/直径、果肉/核比和湿润程度等),以及果实化学性质(果油和果酸含量)进行了记录。结果表明,在盛花期,施加一剂量的腐植酸肥Actosol?(150 cm3)于‘卡拉玛塔’橄榄树滴灌喷头下方的土壤中;在坐果初期,叶面喷施0.5%的腐植酸肥Actosol?,橄榄树产量最高且果实的理化性状最好。
The experiment was carried out in 2011 and 2012, and the ’Calamata’ olive tree planted in private orchards in the province of Ismailia, Egypt, with 10 years of age, was selected as the test material to investigate the effects of spraying different concentrations of 0.125%, 0.25% and 0.5%) of humic acid fertilizer Actosol? (Containing 20% humic acid + NPK 1: 5: 6) on the olive tree; and olive tree yield and fruit quality Size, weight, length / diameter, pulp / nuclear ratio and degree of wetness, etc.) as well as the chemical properties of the fruit (fruit oil and fruit acid content) were recorded. The results showed that at the full flowering stage, a dose of humic acid fertilizer Actosol® (150 cm3) was applied to the soil below the ’Calamata’ olive-tree drip irrigation nozzle. At the early stage of fruit setting, foliar application of 0.5% humic acid fertilizer Actosol ?, The highest yield of olive trees and the best physical and chemical properties of the fruit.
