滨海盐碱地改土造林技术研究

由于自然和人为原因,滨海地区土壤盐渍化问题日益严重,极大地制约了当地的经济发展。受土地条件苛刻、树种单一、病虫害严重、技术不配套等多种因素影响,滨海盐碱地绿化造林的质量和数量受到很大影响。结合文献搜集以及野外调查、实验,提出了滨海盐碱地造林改土降盐措施及绿化造林技术。研究结果表明,轻度盐碱以及造林树种对盐碱要求较低时,可采用基本降盐碱措施结合密植混交,在重盐碱地区和造林树种对盐碱要求较高时,可增加微区降盐改土措施。

Study on the Technique and Method of Amelioration and Forestation in Coastal Alkali-Saline Land

Because of natural factors and artificial factors,the problem of soil salinization in coastal area is becoming serious,and greatly restricts the development of local economy.The quality and quantity of forestation in the alkali-saline soil are affected greatly in virtue of low land conditions,few tree species,severe pests,the unqualified technique,and so on.Combining with field investigation and experiments,the measures of reducing soil salinity and forestation technique were put forward.The results indicat...
