竹类植物对盐胁迫的响应及栽培养护研究进展

Research Progress on Response of Bamboo Plants to Salt Stress and Cultivation and Conservation

土壤盐渍化是全球化的影响农业生产以及环境的重大问题,是农业发展以及林业发展的主要限制因素之一。分析了盐胁迫下竹类植物的生长发育情况,以及盐胁迫条件下植物叶绿素含量、叶片保水力、对植物光合作用和植物生长活力的影响,通过对比其他胁迫与盐胁迫条件下的竹类植物表型去鉴定竹类植物受到的不同胁迫危害。同时针对不同滨海地区的含盐量筛选出适合的竹种,分析了植物栽植前的盐碱土改良方法以及栽种前后的种植养护管理,为竹类植物在滨海沙地的广泛种植提供理论基础。

Soil salinization is a major problem affecting agricultural production and the environment in the globalization,and is one of the main limiting factors for agricultural development and forestry development.This study analyzed the growth and development of bamboo plants under salt stress,as well as the effects of chlorophyll content,leaf water holding capacity,photosynthesis and plant growth vigor under salt stress.The different stress hazards of bamboo plants were identified by comparing the phenotypes of bamboo plants under other stress and salt stress.At the same time,suitable bamboo species were selected according to the salt content in different coastal areas.The methods of improving saline-alkali soil before and after planting and the management of planting and maintenance were analyzed,which provided theoretical basis for the wide planting of bamboo plants in coastal sandy land.
