通过控制不同生物炭添加量和降水量,分析土壤理化性质及黑麦草(Lolium perenne L.)的各项生长指标,探究不同添加量的生物炭对缺水植物生长促进的直接与间接作用。结果表明:生物炭的添加可以提高土壤的田间持水率、土壤中速效磷的含量以及土壤的pH;干旱条件下,增加生物炭的用量能促进黑麦草植株的增高,但高剂量的生物炭抑制黑麦草的生长;生物炭加入并不能持续性的保持土壤中的水分,高浓度(>15%)的生物炭反而增大土壤中水分的流失,但由于生物炭中钾元素为植物对抗干旱提供了必要条件。适当添加生物炭(5 ...

Absorption, Accumulation and Physiological Responses to the Phenanthrene Treatments by Perennial Ryegrass (Lolium perenne L.) [PDF]
多环芳烃污染是近年来受到广泛关注的一个环境问题,但是由于相关研究开展较晚,目前对于多环芳烃污染的植物修复、农产品安全等方面的机理研究仍不充分。 本文以多年生黑麦草(LoliumperenneL.)为研究对象,以菲为多环芳烃的代表,采用溶液培养的手段,探讨了植物对多环芳烃的吸收、积累和体内运输以及植物生长、根系分泌、体内解毒酶的响应,研究结果如下: (1)黑麦草对菲的吸收、积累、运输:黑麦草能够从溶液中吸收菲,并且能够将根系吸收的菲向地上部分运输;黑麦草根系和地上部分吸收菲的浓度与溶液中菲的浓度有关 ...
