日光温室甜樱桃高产高效栽培技术 总被引：1，自引：0，他引：1
甜樱桃又称大樱桃,是春季上市的果品,其果实色泽鲜艳、营养丰富,被誉为"果中珍品",因其上市较其它水果更早,亦有"春果第一枝"之称。樱桃投资少产值高,是当前落叶果树中经济效益最高的树种。在我国目前栽培面积小,产量低;经济价值高。美国农民称大樱桃为"宝石水果",称甜樱桃种植为"黄金种植业(Gold Plantation)"[1]。国内林果部门对大樱桃栽培技术方面的研究较多,但由于大樱桃发展较晚,关于其栽培技术方面的研究较少。因此,分析研究大樱桃栽培技术,对发挥地域优势,发展高效生态农业意义极大。为正确引导甜樱桃产业的健康持续发展,对甜樱桃生产现状、存在问题进行了分析,并提出了发展对策。 相似文献

广西水果产业竞争力分析 总被引：1，自引：0，他引：1
水果是广西的支柱产业,不断提高广西水果产业竞争力,有利于农民收入翻番,解决"三农"问题,构建和谐社会,促进全面建设小康社会。在竞争优势理论分析的基础上,提出水果产业竞争力的概念。把影响广西水果产业竞争力的因素概括为:1)要素条件,包括自然资源、地理位置、生产规模;2)需求条件,包括国内消费需求、国际贸易和消费需求;3)相关和支持产业,包括加工业、运销业、信息业和监管业;4)经营主体。结果表明:要素条件是广西水果产业发展的优势,需求条件既是广西水果产业发展的机遇也是挑战,相关和支持产业是广西水果产业发展的劣势,经营主体薄弱、分散是广西水果产业发展的最大障碍。在此基础上,提出提高广西水果产业竞争力的对策建议:多措并举,鼓励规模经营;接二连三,促进产业发展;紧抓品质,提升市场竞争力;创新思路,强化产业服务。 相似文献

Ecosystem services (ES) concepts and approaches have become more appealing to practice, such as municipal/urban planning, environmental policies and governance to address sustainable development. Inclusion of this concept in the planning or policy discourses is the first step for further implementation on the ground. Using China’s capital, Beijing, as the case study, this article analyzes how ES (or similar concepts) have permeated China’s urban development history since 1949 when the New China was established and how this has to be with China’s urban green space development. The results show: (1) There were no explicit references to “ecosystem services” per se, but overlapping concepts such as “functions”, “values” and “benefits” can be found in planning documents and, importantly, the lack of the concept per se has not affected the detailed services that emerged in all plans. (2) Among the three ES sections, only cultural services run from the beginning to end although the included services kept changing. Other sections show considerable variation and less continuity – the focal services of each stage changed over time. (3) Through the ES lens, some general patterns regarding China’s urban development can be found such as regulation services gradually become valued for their own sake. The patterns found in Chinese planning documents are then compared with some western regions. This study reveals limitations of the past and opportunities for the future to inform urban development decision-making. Adaptation of old and incorporating new ES concepts can improve the quality of plans and foster cities’ ability to learn from past patterns for future sustainability. 相似文献

We examine the potential role of perennial woody food-producing species (“food trees”) in cities in the context of urban sustainable development and propose a multifunctional approach that combines elements of urban agriculture, urban forestry, and agroforestry into what we call “urban food forestry” (UFF). We used four approaches at different scales to gauge the potential of UFF to enhance urban sustainability and contribute to food security in the context of urbanization and climate change. First, we identified 37 current initiatives based around urban food trees, and analyzed their activities in three categories: planting, mapping, and harvesting, finding that the majority (73 %) only performed one activity, and only 8 % performed all three. Second, we analyzed 30 urban forestry master plans, finding that only 13 % included human food security among their objectives, while 77 % included habitat for wildlife. Third, we used Burlington, Vermont as a case study to quantify the potential fruit yield of publicly accessible open space if planted with Malus domestica (the common apple) under nine different planting and yield scenarios. We found that 108 % of the daily recommended minimum intake of fruit for the entire city’s population could be met under the most ambitious planting scenario, with substantial potential to contribute to food security even under more modest scenarios. Finally, we developed a Climate–Food–Species Matrix of potential food trees appropriate for temperate urban environments as a decision-making tool. We identified a total of 70 species, 30 of which we deemed “highly suitable” for urban food forestry based on their cold hardiness, drought tolerance, and edibility. We conclude that substantial untapped potential exists for urban food forestry to contribute to urban sustainability via increased food security and landscape multifunctionality. 相似文献

The success or failure of an investment project in fruit production also depends on the selection of the fruit species and variety. When selecting the variety for the creation of a new orchard it is necessary to perform the synthesis of different data and to look at all aspects of the investment. This paper presents the application of DEX multi-criteria decision making. The model was applied on 7 varieties of plum from the western Balkans region that were assessed by experts from “The association of agricultural economists of Western Balkans” using the Delphi method.By applying this model it has been shown that the ’Stanley’ is the most suitable for starting a new orchard while the varieties ’?a?anska ljepotica’ and ’?a?anska rodna’ are also very suitable for starting new fruit orchards and they have also received the value attribute “very acceptable”.Using this model all strong and weak sides of the observed plum variety were shown. For the final selection it is necessary to conduct research at a specific micro location where all characteristics of that area would also be taken into consideration. 相似文献
