The city green turf grasses are under seriously stress for the shading of tall buildings, trees and shrubs, and lead to the recession of turf grass, so the author studied for this problem; Taking three cold-season sods as test material, including Festuca rubra Pernille、Poa pratensis Kentucky and Agrostis Regent. Effects of different concentrations of uniconazole (S3307) on shade-tolerance of three turf grasses under shading situation were studied by testing long-term growth and physiological characteristics of them.; After treated with S3307, the contents of chlorophyll and soluble sugar increased, plant height decreased, leaves width and thickness increased. All of these indicated that S3307 can evidently improve shade-tolerance of three turf grasses with different shade-tolerance, the optimal concentration of uniconazole is 100~200 mg/L; The results are very useful and meaningful for improving quality of turfgrasses under shading situation.
高大建筑物、乔木及灌木遮荫会使用于城市绿化的草坪草受到严重胁迫,造成草坪草衰退,针对这一难题进行了研究;以耐荫性不同的冷季型草坪草匍匐紫羊茅派尼、草地早熟禾肯塔基、匍匐翦股颖摄政王为试验材料,研究了不同浓度的外源激素稀效唑(Uniconazole, S3307)处理对3种遮荫草坪草生理及生长变化的长期调控作用;经稀效唑处理,3种草坪草叶片叶绿素含量和可溶性糖含量增高,植株株高变低,叶片变宽、变厚,不同耐荫性草坪草的耐荫能力均得到显著提高,最适的处理浓度范围100~200mg/L;这在生产实际中有重要应用价值,特别对提高受遮荫胁迫的草坪质量具有重要意义。

The two catalysts supported on USY zeolites with surface acid amounts of 626 and 203μmol/g, respectively, showed excellent sulfur tolerance, while the catalysts of higher and lower acid amount showed decreased sulfur tolerance. Energy dispersive spectroscopic analysis proved that the support with a large acid amount adsorbed more sulfur, which might lead to the lower sulfur tolerance of the catalyst.
结果表明硫含量为200μg/g时,载体酸量为626和203μmol/g的两个催化剂的耐硫性最好,而载体酸量更低和更高的催化剂的耐硫性较差,表明载体的酸量太大或太小都不利于催化剂的抗硫性。X射线能量散射分析表明,酸量大时S在酸性位吸附很多,这可能导致催化剂中毒。

The microorganisms was domesticated by adding a certain amount of lead in the soil, and three lead-tolerant strains including Pb-R-1, Pb-R-2 and Pb-H-3 accordingly originating from 300 mg/L, 750 mg/L and 900 mg/L lead medium were isolated with a series of PDA medium of different lead concentrations. Through the identification, Pb-R-2 was confirmed as Aspergillus sp., Pb-R-3 as Penicillium sp. The trials of transferring culture showed that all strains had the stable heredity of lead tolerance in different composition PDA medium.
