高寒地区土壤生物炭改良和增温对暴马丁香生长量的影响分析
|
摘要
为促进在高寒地区暴马丁香的生长,利用生物炭对土壤进行不同程度的改良,同时辅以不同程度的土壤增温,确定最适宜暴马丁香生长的土壤改良和土壤增温方式。结果表明:不同程度的土壤改良方式和土壤增温处理对暴马丁香的生长均有促进作用,其中,以30%～40%比例的生物炭进行土壤改良,同时辅以2～3℃的土壤增温处理时,暴马丁香的各项生长量达到最大值,树高、胸径、冠幅的最大增量依次为23.39 cm、1.5 cm和21.17 cm,为该地区土壤改良的最佳方案。
In order to promote the growth of Syringa reticulata in severe cold district, the effects of soil improvement methods and soil temperature on the growth of Syringa reticulata were studied. Results shows that different degrees of soil improvement methods promoted the growth of Syringa reticulata. Among them, when the soil was improved from 30% to 40% of biochar, and supplemented with soil temperature of 2-3 ℃, the growth of clove reach the maximum value,the growth of Syringa reticulata reach the maximum, the height of the tree, the diameter of the breast and the increase in crown width is 23.39 cm, 1.5 cm & 21.17 cm, which is the optimal solution for soil improvement in the region.
