Effect of Exogenous NO on Germination in Cabbage under Salt Stress [PDF]
, 2008 以硝普钠作为外源一氧化氮(nitric oxide,NO)供体,研究NO对盐胁迫下小白菜种子萌发的影响.结果表明:小白菜在5‰盐度下生长情况最好;较高盐度(15‰)下,种子萌发和生长受到明显抑制,30‰盐度完全抑制种子萌发.较低盐度海水可以作为植物生长的营养液,促进小白菜种子萌发;外加0.01 mmol/L SNP能够提高白菜种子的发芽率、发芽指数.In this paper,effect of NO on germination of Cabbage under salt stress ...

Shuitu Baochi Xuebao, 2007 在调查北京八达岭林区刺槐(Robinia pseudoacacia)、侧柏(Platycladus orientalis)及其混交林生长量、土壤理化性质、水源涵养能力、病虫害的基础上,研究其结构与功能关系.结果表明,混交林比纯林具有更好的生长量,土壤理化性质得到进一步改善,从而提高水源涵养能力.另外,混交林还能够提高林分抵抗病虫害的能力.采用混交的方式为:1行刺槐3行侧柏循环混交,刺槐株数不超过1/4.本项研究以期对北京市森林健康经营具有一定的指导意义.

Shuitu Baochi Xuebao, 2004 以黄土高原主要造林树种刺槐、油松为材料,以坡地常规造林技术为对照,研究了退耕坡地大鱼鳞坑覆膜打孔滴灌技术,使水通过滴灌管缓慢滴入土壤深处,避免了水分无效蒸发,可使刺槐造林成活率达到98 7%,油松达到91 4%,分别比对照提高了36 6%和38%。在降雨量相同的情况下可明显促进幼树生长,刺槐3年平均生长量比对照提高28 1%,油松提高39 3%,树冠投影面积增加2倍。在中强度降雨2次/a、总降雨量387 4mm情况下,25°坡地土壤侵蚀模数下降至2500t/(a·km2)以下。

Shuitu Baochi Xuebao, 2002 采用土钻法和盆栽试验研究了渭北地区主要造林树种的垂直根系分布特征及其抗旱性。结果表明立地条件对刺槐根系分布特征有明显的影响 ,林地土壤水分状况的差异是造成这种影响的关键所在 ;土壤种类、结构等对刺槐根系的分布特征也有很大的影响 ;不同树种在根系垂直分布特征方面存在着很大的差异 ,其中刺槐的根系分布最深 ;在一定的土壤干旱范围内 ,苗木可以通过提高根系活力来适应逆境 ,当土壤干旱超过一定的阈值后 ,树木根系将逐步丧失其活力和功能 ,最终导致地上部分的枯死 ;在供试的 4个树种中 ,山杏根系的抗旱性最强 ...
