滨海重盐碱地柽柳造林新模式探讨

New Mode Study of Tamarix chinensis Forestation in Binhai Saline Alkali Land

利用柽柳耐水湿、耐土埋的生理特性,采用节水容器栽培等相关技术,结合柽柳育苗过程进行系列造林试验。结果表明:苗木根系插入装淡水的小口塑料瓶后,再栽植的造林模式,在淡水缺乏的滨海重盐碱地造林不仅具有成活率高、成林快、幼林保存率高等优点,而且对于增加土壤有机质、降低地下水位、抑制土表返盐、丰富盐碱地植被种类等方面也具有明显的成效,是节水高效、成本低廉的滨海重盐碱地柽柳造林的新模式。

By using relative technology of water-saving container, cooperating Tamarix chinensis seedling process for series of affores- ting testing,we explored a new water-saving and low cost mode of Tamarix chinensis forestation in Binhai saline alkali land. This mode applied in fresh water shorted severe saline alkali land has advantages of high survival rate, fast foresting, high existing rate of young forest; and it has obvious effects to increase soil organic matters, decrease the underground water level, prevent salt back to soil surface, enrich the variety of vegetation in saline alkali land.
