本研究于2011年,2012年间进行。选择种植在埃及北西奈省私人果园沙土上的10年生“皮夸尔”橄榄树。试验研究了4月到6月期间,每棵果树灌溉滴头下的土壤中施加不同浓度(150 cm3,75 cm3和50 cm3)的Actosal(腐植酸20%+氮磷钾1∶5∶6)的作用。在生长季末,记录产量(千克/棵)和果实质量:平均果实大小(体积)、重量、形状指标(长/直径)和果肉/核比,以及果实化学特性:果油和果酸含量。试验数据表明,在盛花期的第一周,在每棵“皮夸尔”橄榄树土壤中一次性施加150 cm3腐植酸肥Actosol后,果树产量最高(千克/棵),同时果油和果酸含量也比分两次土壤施加(盛花期和盛花期后一个月分别施加75 cm3)腐植酸高,或者分3次施加(盛花期施加50 cm3,盛花期后一个月,以及盛花期后两个月分别施加50 cm3)腐植酸高。施加Actosal后与对照组相比,大部分果实质量参数会明显下降。
This study was conducted in 2011 and 2012. Choose the 10 year old Picquier olive tree planted on the sand of private orchards in North Sinai Province, Egypt. The experiment studied that from April to June, Actosal (humic acid 20% + NPK 1: 5: 6) with different concentrations (150 cm3, 75 cm3 and 50 cm3) Role. At the end of the growing season, yield (kg / tree) and fruit quality were recorded: average fruit size (by volume), weight, shape index (length / diameter) and pulp / kernel ratio, and fruit chemistry: fruit oil and fruit acid content. The experimental data showed that in the first week of full flowering, fruit trees produced the highest yield (kg / tree) after applying 150 cm3 of humic acid fertilizer to each “Picquar” olive tree soil at the same time. The acid content was also higher than that of two soil applications (applying 75 cm3 in full bloom and one month after full bloom), or applying 3 times in full bloom (50 cm3 in full bloom, one month after full bloom, and two Months were imposed 50 cm3) humic acid high. After applying Actosal, most of the fruit quality parameters decreased significantly compared with the control group.
