大叶黄杨扦插池育苗技术 总被引:3,自引:0,他引:3
大叶黄杨(别名:冬青卫矛、法国冬青、四季青、日本卫矛、万年青、正木)卫矛科卫矛属,是黄杨的一个变种,有金边大叶黄杨、银边大叶黄杨、金心大叶黄杨和斑叶大叶黄杨等,灌木或小乔木,体态丰满,生长缓慢,枝叶繁密,叶革质、有光泽,更具美丽花纹或斑点,枝条柔韧,易于绑扎造型,可修剪成圆球形、花篮形等点缀园林,四季常青,苍干虬枝,能和金雀、迎春、桧柏媲美,别具风格,对各种有毒气体(二氧化硫、氯气、氯化氢等)及烟尘有很强的抗性。 相似文献

<正>大叶黄杨(Evonymus japonicaL.)为卫矛科卫矛属植物。它四季常绿,花叶有多个变种、色泽秀丽,树姿优美,耐修剪,耐捆扎,是优良的城市园林绿化树种,又是较好的盆景制作材料。大叶黄杨的繁殖主要靠无性繁殖,形式有压条、靠接和扦插。前2两种繁殖方法,繁殖的速度慢、繁殖的数量少,而采用扦插繁殖,不仅技术简单易学,而且成活率高(达92%)、繁殖时间短、成本低、效益高,可进行大批量生产和集约化经 相似文献

大叶黄杨播种育苗技术研究 总被引:4,自引:0,他引:4
试验采用营养袋播种育苗方式进行大叶黄杨不同覆盖方式、不同基质的对比试验。结果表明:不同覆盖方式对大叶黄杨种子的发芽率具有极显著影响,以谷皮+塑料小拱棚的发芽率最高,达87.7%;不同基质对大叶黄杨播种苗的生长量具有极显著影响,以混合基质(黄心土∶粗河沙∶草木灰+0.5%钙镁磷肥=1∶1∶1+0.5%)最优,苗木平均高、地径、主根长度分别达14.5 cm、0.22 cm、19.0 cm,≥5 cmⅠ级侧根平均条数达3.6条/株。 相似文献

The stem bark of Euonymus japonicus Thunb. led to the isolation of three new glycosylsphingolipids (1–3), 1-O-[-L-rhamnopyranosyl-(1 → 2)-β-D-glucopyranosyl]-(2S,3R,9E)-2-N-[(2R)-hydroxystearoyl]-octadecasphinga-9-ene (euojaposphingoside A, 1), 1-O-[β-D-glucopyranosyl-(1 → 2)-β-D-glucopyranosyl]-(2S,3R,4R,11E)-2-N-[(2R)-hydroxydocasanoyl]-octadecasphinga-11-ene (euojaposphingoside B, 2), 1-O-[β-D-glucopyranosyl]-2′-O-[β-D-glucopyranosyl]-(2S,3R,4R,11E)-2-N-[(2R)-hydroxytetracosanoyl]-octadecasphinga-11-ene (euojaposphingoside C, 3) along with three known glycosylsphingolipids (4–6), 1-O-[β-D-glucopyranosyl]-(2S,3R,9E)-3-hydroxymethyl-2-N-[(2R)-hydroxynonacosanoyl)-tridecasphinga-9-ene (4), 1-O-[β-D-glucopyranosyl]-(2S,3R,9E,12E)-2-N-[(2R)-hydroxytetracosanoyl] octadecasphinga-9,12–diene (5), 1-O-[β-D-glucopyranosyl]-(2S,3R,5R,9E)-2-N-[tridecanoyl] nonacosasphinga-9-ene (6), lupeol (7), stigmasterol (8), sitosterol (β and α) (9,10) and β-carotene (11). The structure of all the compounds was achieved by spectroscopic and chemical data analysis. The antiplasmodial, antileismanial and cytotoxic activity of all compounds was tested. 相似文献

In order to prevent severe pollution by de-icing salt on greenery along urban roads, a half lethal dose (LD_50)for a plant population was confirmed through stress simulation of chloride de-icing salt on Euonymus japonicus, with an ianalysis of physiological changes, statistics on mortality rate on plant populations and mathematic modeling during a 30- day subacute toxicity test. The results indicate that a significant positive correlation in the early stages and a significant negative correlation in the later stages were observed between the amount of chlorophyll a and b in plants and a cumulative dose of de-icing salt. The amounts of free proline in plants and the dose of de-icing salt were positively correlated Over the entire period. No significant correlation in the initial stage, but a significant negative correlation in later stages was observed between the soluble protein and the dose of de-icing salt. LDs0 of this chloride agent on E. japonicus is 5 kg.(L·m2)-1 over 30 days. 相似文献

通过田间对比试验,对大叶黄杨叶片在冬季自然降温条件下相对电导率、可溶性蛋白含量等生理生化指标的变化规律进行了详细的研究。结果显示:1)在自然降温条件下大叶黄杨各层叶片的相对电导率先急骤上升后缓慢下降;中层叶片电导率增加缓慢,数值低于上、下层;经处理后的大叶黄杨叶片电导率增幅小于对照。2)随着气温的下降,大叶黄杨叶片细胞中可溶性蛋白含量在1月达到最高值后又快速下降;2种处理的中层叶片比上、下2层叶片中可溶性蛋白质含量变化较小;对照的可溶性蛋白质含量较处理1的增幅小。 相似文献
