Abstract

It is necessary to carry out replanting  activities  to increase  the production and productivity of oil palm plants.  Rejuvenation of oil palm plantations can be done through an inserting system  and totally rejuvenation system. The population propagation of horn beetles  growed faster  in oil palm plantations with inserting rejuvenation system than in totally rejuvenation system. This study aimed to obtain an accurate information on the population of horn beetles in oil palm plantations. The research has been conducted on  July-August 2020  in Talang Bukit Village as an inserting system area Talang Datar Village as a totally rejuvenation area, Bahar Utara District, Muaro Jambi Regency, Jambi Province. An unformated trial was carried out as an experimental design and the location determination was purposively chosen  for there were plants under study and showed a uniform condition at that location.  the sampling locations based on oil palm plantation rejuvenation systems, namely: (1) inserting rejuvenation system, and (2) totally rejuvenation system. There were 15 / Ha population at oil palm plantation with inserting rejuvenation system,  while there were 3 horn beetles/Ha in totally rejuvenation system. The percentage of horn beetle attacking was 22,22 in  inserting rejuvenation system while it was only 3.70%. in the  totally rejuvenation system.Key words: population, horn beetle,  rejuvenation, oil palm
为了提高油棕的产量和生产力,有必要开展再植活动。油棕种植园的恢复可以通过插入系统和全面恢复系统来实现。在插入返老还老的油棕人工林中,角甲种群繁殖速度比完全返老还老快。本研究旨在获得油棕种植园中角甲种群的准确信息。该研究于2020年7月至8月在占比省Muaro Jambi县Bahar Utara区Talang Bukit村作为插入系统区Talang Datar村作为全面复兴区进行。采用非格式试验作为试验设计,有目的地选择研究植物的位置,并在该位置显示出统一的条件。采样地点基于油棕种植园返青系统,即:(1)插入返青系统和(2)完全返青系统。插入式复壮油棕人工林有15只/Ha,完全复壮油棕人工林有3只/Ha。插入回春系统中,角甲攻击率为22.22%,而只有3.70%。在完全恢复活力的系统中。关键词:种群;角甲虫;返老还童
