<正> 长期以来,小粒种咖啡单产很低,产量在100~200斤/亩间徘徊,主要原因是栽培管理技术落后和选育种工作跟不上。为此,我们从1980年开始对小粒种咖啡早熟、高产综合栽培技术进行了系统研究。试验的1.53亩小粒种咖啡定植第二年就能投产,并取得亩产600.3斤干豆的高产,以后连续两年亩产都在710斤以上。这充分表明小粒种咖啡的丰产潜力是很大的,关键在于科学的种植和管理。现将几年来对早产高产综合栽培技术的结果概述如下: 相似文献

<正> 我省在五十年代末和六十年代初小粒种咖啡生产中普遍采用每亩种植222株以下的密度,单位面积干豆产量较低。八十年代初,潞江农场在1958年建立的2.4亩适当密植试验的基础上,采用亩植400株左右的密度,获得了高产。近年来,国外一些咖啡植区进行小面积高密度栽培试验结果亦获得了高产。在云南低海拔咖啡植区环境条件下,小粒种咖啡究竟以何种种植密度为宜?我们于1981—1985年布置了小粒种咖啡不同种植密度试验,试验结果如下: 相似文献

云南小粒种咖啡高产栽培中存在的问题与对策 总被引:2,自引:0,他引:2
云南省的咖啡产量占全国的90%以上,占全球产量的0.4%左右,其单产是世界最高,云南出产的咖啡产品逐渐享誉海内外,截至2012年,云南种植面积达6.67万hm2。但目前云南小粒种咖啡栽培中尚存在着盲目种植、资金投入不足、缺乏科学栽培和管理技术、病虫害严重等问题。藉此提出合理选址,科学种植,拓宽投融资渠道,保障资金投入,加强科学栽培与管理,有效防治病虫害,加强政策扶持等高产栽培的对策与措施。 相似文献

Coffee leaf rust (CLR), caused by Hemileia vastarix, is one of the most serious diseases of coffee plantations and cause great losses in coffee production. We aimed to examine coffee varieties, shade, age of coffee plants, coffee plant density and soil properties in relation to CLR infection. To do this, we established a total of 75 plots in three agroforestry coffee plantations in the central Peruvian Amazon. We gathered data there in 2011 (dry season) on the presence/absence of CLR; coffee variety; age and density of coffee plants, and also took hemispherical photographs to determine canopy openness. In 2014 (wet season), we again gathered data on the same variables. In 2012, we collected soil samples from a subset of the plots. At all plantations, coffee variety had a significant effect on CLR incidence, with the Catimor variety infected less frequently than Caturra. Coffee plant age had a significant positive effect on CLR incidence. Increasing coffee density also increased CLR incidence for some of the studied plantations/seasons. Comparing those plots from which data were collected in the dry and wet seasons, we found that CLR presence was significantly higher in the wet season. The effect of shade on CLR incidence was not clear. Catimor and Caturra varieties showed opposite trends of CLR incidence in response to shade quantity in most cases (Caturra variety CLR incidence was decreasing with shading increase and Catimor CLR incidence decreasing with decreasing shading). Finally, the soil properties did not affect CLR incidence. 相似文献

ABSTRACT The biophysical characteristics of the farm and farmers’ socioeconomic factors have been used to explain adoption of technologies in Africa. However, agricultural technology adoption requires that we also understand the psychological factors that can encourage or discourage farmer adoption of technologies. The aim of this article is to assess the psychological drivers of farmers’ intentions to adopt agroforestry technologies on their farms. We obtained data from 400 smallholder farmers in the Mt. Elgon region of Uganda. The Theory of Planned Behavior was used as the main framework. Quantitative data were analyzed using structural equation modeling to assess the impact of a set of psychological factors on farmers’ intention to integrate trees in coffee. The intention of farmers to integrate trees in coffee plantations was mainly driven by their evaluation of the benefits of shaded coffee (attitude) followed by beliefs about their own capability (perceived behavioral control). However, social pressure (subjective norm) was insignificant, implying that smallholder farmers tend to deny the influence of other people’s behavior on their actions. Therefore, farmers’ positive evaluation of shading coffee and the perceived capability to overcome tree planting barriers reinforced their intention to integrate trees in coffee. This renders attitude and perceived behavioral control as reliable predictors of farmer tree planting behavior, especially in the context of developing countries. 相似文献
