摘要
摘要:瓜拉那是一种原产于亚马逊地区的植物,其果实被称为瓜拉那。瓜拉那的生产是由小农进行的,是农村和城市地区成千上万人的收入来源。杂草与瓜拉那竞争造成的干扰是制约瓜拉那生产的重要因素。尽管它具有重要的经济和社会意义,但对其管理的研究很少。因此,本研究旨在研究杂草干扰对不同时期瓜拉那产量的影响。本研究于2014年和2015年季节在美国莫萨姆斯进行。试验设计为随机区组设计,8个处理4个区组。处理包括4个不同时期(3 - 5月、6 - 8月、9 - 11月和12 - 2月)的控制或与杂草共存的组合。杂草群落由12科23种杂草组成,其中重要值指数最高的是雀稗(Paspalum virgatum),占55.74%。6 ~ 8月与瓜拉那共存的杂草产量最低(156.16 kg hm -1),而同期对照的产量最低(309.05 kg hm -1)。从6月到8月,杂草的干扰使瓜拉那的产量减少了50%。
ABSTRACT: Guarana is a plant native to the Amazon region that produces the fruit known as guarana. Guarana production is carried out by small farmers and is a source of income for thousands of people in rural and urban areas. The interference caused by the competition between weeds and guarana is an important limiting factor of its production. Despite its economic and social importance, there are few studies on the management of weeds in this species. Thus, this research aimed to study the effects of weed interference on guarana yield in different periods. This study was performed in Maués, AM, in the 2014 and 2015 seasons. The experimental design was a randomized block design with eight treatments and four blocks. Treatments consisted of a combination of four different periods of control or coexistence with weeds (March to May, June to August, September to November, and December to February). Weed community was composed of 23 weed species belonging to 12 botanical families, with Paspalum virgatum being the species with the highest importance value index (55.74%). Weed coexistence with guarana from June to August provided the lowest yields (156.16 kg ha-1 of grains) when compared to weed control in the same period (309.05 kg ha-1 of grains). Weed interference from June to August reduced guarana yield by 50%.
