茶行业的兴起为茶园园林的建设带来了新的机遇,随着人们对茶的关注度不断提升,茶园园林的建设量越来越多,而且茶园园林建设的技术性也不断凸显。在现代茶园园林的设计规划中,采用计算机应用软件逐渐成为了一种趋势,并且也起到了十分明显的效果,大大减轻了设计人员的工作量,与此同时,计算机应用软件的不断创新和增多也促进了茶园园林整体设计效果的提升,据此本文就以计算机应用技术入手,对其在现代茶园园林的设计规划中应用进行了分析研究。 相似文献

风景园林设计与茶文化有着紧密的关系,茶类植物作为园林景观植物,在园林中有着很重要的地位。因为茶树物种丰富,叶型多类,植株类型也不少,具备作为园林观赏植物的特点,所以关于它的资源利用从很久前就开始了。本文通过茶文化与园林文化的探究,对茶类植物在园林设计中的相关配置和利用方式进行了分析和展望。 相似文献

[目的]筛选适宜克拉玛依地区种植的北美海棠品种。[方法]从北京植物园种苗中心引进的6个北美海棠品种,于2004年4月―2007年11月在三圃基地内种植,观察各品种的生物学和物候学特征、耐寒、耐热、耐旱、耐荫性、抗病性及繁育方式,并进行推广示范试验。[结果]引种的6个北美海棠品种在克拉玛依气候土壤条件下均能正常生长、发育、开花、结果;钻石、雪球、绚丽、凯尔斯和霍巴5个北美海棠品种表现出较强的抗寒、耐热、耐旱和抗病性,但草莓果冻海棠在耐寒、耐热和抗病性方面表现不佳,不适宜在克拉玛依地区推广种植。[结论]除草莓果冻海棠,其他5个引种北美海棠品种均具有很高的观赏和推广应用价值。 相似文献

Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) is an invasive species that has become an important orchard pest in the Mid-Atlantic region of the US. Adults and nymphs feed on tree fruit. Feeding injury from adults has been characterized but the injury from nymphs has not been examined systematically. Since the four plant-feeding instars of H. halys (second through fifth) differ substantially in size, it is plausible that the effects of their feeding on fruit injury and injury expression may differ among them. We compared feeding injury at harvest from young nymphs (second plus third instars), older nymphs (fourth plus fifth instars), and adults that were caged on ‘Smoothee Golden’ apples and ‘Redhaven’ peaches in early June (peach and apple), late July (peach), and late August (apple). Individual apples and peaches were caged at fruit set and assigned to the following treatments (n = 28/treatment): 1) control (no H. halys), 2) young nymphs or 3) adults early in the season, and 4) young nymphs, 5) older nymphs or 6) adults later in the season. Fruit in each treatment were exposed to 3–4 young nymphs, two older nymphs or 1–2 adults placed in the cages for 96 h and evaluated for external and internal feeding injury within 36 h after harvest. No injury was recorded from unexposed peaches or apples. The percentage of injured fruit and number of injuries per fruit varied significantly among the exposed treatments. Early season feeding by young nymphs yielded the least injury to peaches and apples. In apples, the highest percentage of injured fruit and number of injuries per fruit were caused by late season feeding by adults. In peaches, early season adult feeding produced the highest percentage of injured fruit and injuries per fruit. More internal than external injury was recorded on peach and no such difference was observed on apple. The implications of these findings on H. halys management in fruit orchards are discussed. 相似文献

为明确不同浓度40%溴酰·噻虫嗪SC对苹果绵蚜的田间防效及苹果品质的影响,2018年在云南昭阳区苹果主产区果园,采用以清水灌根为对照,40%溴酰·噻虫嗪SC 500倍液、750倍液、1000倍液在落花期至幼果形成期灌根处理进行防控苹果绵蚜效果评价。结果表明,3个浓度的40%溴酰·噻虫嗪SC溶液均可持续降低苹果绵蚜虫落数,增加虫口减退率,对苹果绵蚜均有较好较长的防效,其中750倍液40%溴酰·噻虫嗪SC对绵蚜防效最好,500倍液和1000倍液的防效次之;品质分析表明,40%溴酰·噻虫嗪SC处理可增加苹果可溶性固形物和可溶性蛋白含量,而可溶性糖、可滴定酸和维生素C含量显著降低。从降低农药施用量及保证苹果品质出发,生产中建议以750倍液、1000倍液40%溴酰·噻虫嗪SC防治苹果绵蚜为佳。 相似文献

A reduction in the number of wounds of pears and apples which developed blue mould (Penicillium expansum) infection was associated with reduced spore concentration. An experimental ultraviolet irradiation treatment of water in a fruit-handling system reduced both spore numbers and fruit rots, but not to a level which would suggest that the technique is worth pursuing to a commercial application stage. 相似文献
