梅园改建及新增的景点建筑设计清芬轩1960年4月，梅园扩建工程正式启动。拆除了老园东西侧围墙，新老园子在规划上不作分隔，强调相互问的引连、交融，寻求两者过渡、渗透、交替、脱卸的结合点。经多次踏勘、反复推敲， 相似文献

中国北方城市梅花应用探析 总被引：1，自引：0，他引：1
梅花,是我国的传统名花,是中国园林中最具特色的植物造景材料之一,但是,由于气候等方面的原因,梅花在我国北方的应用非常有限,本研究筛选出了普遍适合我国北方气候的梅花品种,并分别探讨了我国北方城市梅花在专类园、公园、风景区、道路广场、庭院居室等地方的应用问题,希望可以将极具中国特色的梅花更加合理更加广泛的应用于我国北方城市园林的建设中,从而丰富北方城市冬季景观,有利于弘扬我国博大精深的梅文化。 相似文献

为制定合理的核桃园管理制度,以新疆林业科学院佳木试验站6个核桃园为对象,研究了不同树龄及管理措施对核桃园土壤化学性质的影响。结果表明:土壤有机质和速效氮含量以树龄最高且不施肥的1号核桃园最高,其值分别为23.97和86.67 mg/kg;土壤全氮和全磷含量以施肥量最高且采用免耕法的5号核桃园最高,其值分别为1.13和0.82 g/kg;土壤速效磷及全钾含量以树龄及施肥量较高且采用落叶覆盖的3号核桃园最高,其值分别为61.5和62.59 g/kg;土壤速效钾含量以施肥量最高且采用少耕法的4号核桃园最高,其值为158.93 mg/kg。基于隶属函数法的土壤肥力质量综合指数评价结果显示,6个核桃园土壤质量综合指数由大到小依次为5号(0.81)、1号(0.71)、4号(0.56)、3号(0.37)、6号(0.20)、2号(0.02);基于主成分分析法的土壤质量评价结果显示,6个核桃园综合排名为:5号(1.97)、1号(1.02)、4号(0.31)、3号(0.10)、6号(-1.44)、2号(-2.10)。2种评价方法结果一致,且土壤质量与有机质含量基本呈正相关。从土壤质量来看,高施肥量及免耕法的管理措施较利于土壤持续利用,其次落叶覆盖的无人为干扰的树龄最高的核桃园土壤质量也较好。 相似文献

Pollen contamination was evaluated using control-pollinated seedlings pollinated with polymixes of orchard pollen and pure wildstand and wind-pollinated orchard seedlings. At age 7, seedlings pollinated with contaminate pollen were the shortest across all four sites, but had survival levels (83%) similar to open-pollinated (84%) and pure orchard seedlings (86%). Open-pollinated seedlings had intermediate heights while pure orchard seedlings were tallest. The level of pollen contamination in open-pollinated seedlots was estimated to be 26%. Survival for all pollen sources combined was similar at the two high-elevation sites (84%) and low-elevation sites (86%). Using a yield model to compare volume/ha at rotation age for open-pollinated orchard seedlings and pure orchard seedlings, differences were small and increased due to site index (SI; from 3 to 6?m3/ha) but not due to planting density. Equivalent discounted benefits at rotation were 27 vs. 54 C$/ha at the two extreme site indices (18 vs. 25), respectively. These projected reductions due to pollen contamination are magnified by the large area that is regenerated annually with orchard seed of coastal Douglas-fir and contamination can cause a reduction in benefits of up to C$748,500 per year at the highest SI at a planting density of 1111 trees/ha. 相似文献

To explain the high background pollination rate detected in earlier studies, this study investigated the flowering phenology of a Scots pine seed orchard with respect to airborne pollen occurrence during 1992 and 1993. The receptive period of the female strobili and the shedding period of the male strobili were observed visually. Airborne pollen was monitored with Rotorod traps located inside and outside the seed orchard. There was no time gap in the onset of flowering between the earliest female and male strobili in 1992. Female flowering began 3 days earlier than male flowering in 1993, and the earliest strobili were probably pollinated by pollen transported long distance from more southerly areas. The almost simultaneous peak in pollen occurrence inside the seed orchard and in surrounding pine stands indicates that the seed orchard clones are not temporally isolated from sources of contamination. However, pollen concentrations inside the seed orchard were higher than those in the surrounding stands. Therefore, flowering phenology cannot sufficiently explain the observed pollen contamination rates in this seed orchard. 相似文献

Mating system parameters and pollen contamination were estimated in an 11-year-old Pinus brutia Ten. clonal seed orchard, located in Antalya, Turkey, with the aid of isozymes. Isozyme analysis was performed on both maternal
(megagametophyte) and embryo tissues of seeds collected from the seed orchard and the surrounding natural stand. Fourteen
loci encoding nine enzyme systems were assayed. Based on a multilocus estimator, the proportion of viable seeds originating
from outcrossing (tˆm) in the seed orchard was found to be 0.947; the remainder (0.053) was due to selfing. We estimated that 85.7% of the orchard
seed resulted from pollen contamination by trees in surrounding stands. This may be related to the young age and subsequent
low pollen production of the orchard. Only 9% [i.e., 1.0−0.857 (contamination)−0.053 (selfing) = 0.090] of the orchard offspring
was due to cross-pollination among clones within the orchard. Due to the high level of pollen contamination, it is estimated
that genetic gain in this seed crop is less than 57% of that expected if all offspring resulted from random mating among orchard
clones (i.e., no contamination). 相似文献

The effects of top pruning on subsequent seed and pollen cone production in lodgepole pine (Pinus contorta Dougl.) grafted clones in two seed orchards were evaluated. In the older orchard (14 years old), three pruning regimes were applied: an untreated control, a moderate pruning where 25% of the crown was removed and a severe pruning where 40% of the crown was removed. In the younger orchard (ten years old), only a control pruning and a severe pruning (50% of crown removed) were applied. Five-year seed cone production was lower in treated ramets compared to controls in both orchards. However, when cumulative seed cone yields were adjusted for reduced tree heights after pruning, differences were no longer significant in the older orchard. Strong clonal variation was observed in seed cone yields in both orchards. Pollen cone development was less variable among treatments in the older orchard. In the younger orchard, controls consistently produced heavier pollen crops. Pruning recommendations for similar orchards are made and results discussed for reducing the impacts of losses in seed cone yields.Deceased 相似文献
