鲜食枣产业是我国红枣产业的有机组成部分,从制干枣向鲜食枣转型是我国红枣产区摆脱危机的途径之一。文章以山西临猗鲜食枣的发展为例,采用逻辑分析、比较分析等方法对其研究。结果表明,优势光热资源和良好的立地条件是鲜食枣发展的基本前提;鲜食枣产业是一个典型的资金密集型产业;鲜食枣产业是一个典型的精耕细作劳动密集型产业;鲜食枣产业是一个典型的市场高效率型产业。最后,提出鲜食枣产业发展的建议:适度规模发展是产业健康发展的基础;品质管理是产业健康发展的生命;提高设施大棚的机械化、智能化管理水平和增强鲜食枣产业的社会化服务水平是产业健康发展的保障。 相似文献

为了优化河北省枣产业市场结构,促进河北省枣产业发展,运用哈佛学派SCP分析范式,从枣产业市场集中度、产品差异、市场壁垒3方面入手分析河北省枣产业市场结构.结果表明：枣产业市场集中度较低;产品差异化程度较低;粗加工企业进退壁垒低,精深加工企业进退壁垒高.据此提出优化枣产业市场结构的对策建议：扩大枣产品生产供给能力,推动枣产业集群发展;大力推进品牌战略,提高产品差异化程度;提高枣精深加工能力和核心竞争力;出台激励政策,完善质量检测体系. 相似文献

Physio-Biochemical Changes in Jujube Fruits(Zizyphus jujuba Mill. cv. Lingwuchangzao) at Mature Stage 总被引：3，自引：0，他引：3
The changes of physiological and biochemical indices in jujube fruits during the late development were investigated from 6-year-old jujube trees (Zizyphus jujuba Mill. cv. Lingwuchangzao). The results showed that the flesh firmness decreased slowly from white-green stage to full-red stage, being significantly related with the developmental maturity of jujube fruits negatively, the correlation coefficient reached -0.980 3**. The contents of ascorbic acid and titratable acid in jujube fruits were significantly related with the developmental process of jujube fruits negatively or positively, the correlation coef-ficients were -0.973 1** and + 0.974 6** respectively. The contents of soluble solids, total sugar, and sucrose increased with jujube ripening, while the relative sweetness of jujube fruits showed the same variation pattern, the correlation coefficients were 0.996 6** , 0.988 0** , and 0.982 8**, respec-tively. Befcre white-green stage during fruit development,the accumulation d moncsaccharide was predom/nant in jujube fruits, following a fast accumula-tion of sucrose, indicating that the main component of sugars is sucrose at the crisp-ripe stage. Furthermore, the starch content of the flesh reached the peak at about thirty percentage of jujube maturity, being 51.54 mg/100 g · FW. The respiratory rates varied between 10 mg/(kg·h) and CO2 26 mg/(kg·h) after fruit turning red and before softening, indicating a non-climacteric respiratory type. 相似文献

新疆骏枣氨基酸营养价值评价 总被引：1，自引：0，他引：1
为了初步探明新疆主栽骏枣氨基酸差异性及营养价值,为合理优化利用骏枣资源提供理论依据。以山西交城骏枣为参照,通过模糊识别法、系统聚类法,对新疆11县市骏枣氨基酸指标数据进行分析。结果表明新疆不同产区供试骏枣的氨基酸总量较高,且各产区骏枣中所含缬氨酸(Val)、亮氨酸(Leu)、苏氨酸(Thr)、赖氨酸(Lys)、苯丙氨酸(Phe) 5种必需氨基酸含量间存在较大差异;不同产区骏枣中氨基酸蛋白模式贴近度基本一致;新疆骏枣氨基酸比值系数分(SRC)整体优于交城骏枣,不同产区骏枣氨基酸中Val的氨基酸比值系数(RC)值最低,为第一限制性氨基酸;不同产区经聚类可分为3类,骏枣蛋白质品质评价较好的为阿瓦提县、策勒县和阿克苏市。新疆11县市骏枣蛋白质中氨基酸组成各具特点,且阿瓦提县、策勒县、阿克苏市骏枣蛋白质组成更符合人体蛋白营养需求,宜深化利用。 相似文献
