松柏柽柳盐碱地造林试验

Afforestation Experiment of Conifer Tamarisk in Saline Alkali Land

以2年生松柏柽柳裸根截干苗和营养钵苗木为试验材料,研究了不同盐碱地类型、不同苗木类型对松柏柽柳造林成活率和苗木生长情况的影响,并通过灌水和施用土壤改良剂研究了不同土壤改良处理对土壤全盐含量和松柏柽柳苗木生长的影响。结果表明,松柏柽柳在干旱盐碱地的造林成活率比下湿盐碱地高且苗木生长量较大,营养钵苗木造林成活率高于裸根截干苗;适宜的土壤改良措施为灌水量120 kg/株,土壤改良剂10 kg/株。

The effects of different saline alkali land types and different seedling types on the afforestation survival rate and seedling growth of Conifer tamarix were studied, taking 2-year-old Conifer tamarix bare root pruned seedlings and nutrient bowl seedlings as experimental materials. The effects of different soil improvement treatments on the total salt content of soil and the growth of Conifer tamarix seedlings were studied through irrigation and application of soil conditioner. The results showed that the afforestation survival rate of Conifer tamarix in arid saline alkali land was higher than that in wet saline alkali land which growth of seedlings was larger. The appropriate soil improvement measure was 120 kg/plant of irrigation water and 10 kg/plant of soil conditioner.
