摘要
为了提高乌兰察布地区油松容器苗在立地条件差、土壤贫瘠环境下的成活率和生长量,试验分别采用常规整地、集水整地和菌根菌剂造林技术对油松容器苗进行栽植处理.3年间观察并测定苗木成活率、生长量以及土壤水分指标,通过隶属函数值法评价不同造林技术的抗旱性.结果发现:3年试验期间(2014-2017年),相比常规整地和集水整地造林技术,菌根菌剂造林技术能够显著提高试验区油松容器苗的成活率和生长量;采用菌根菌剂处理的样地土壤水分明显高于常规整地和集水整地;将集水整地和菌根菌剂造林技术相结合,油松容器苗成活率、生长量和土壤水分指标均优于其他3种单独造林技术.此外,不同造林技术的抗旱性评价由高到低为:集水整地与菌根菌剂造林技术结合＞菌根菌剂造林技术＞集水整地造林技术＞常规整地造林技术.
Abstract
In order to improve the rate of survival and the increment of Pinus tabuliformis container seedling planting in the poor area in Ulanqab,the study planted the seedlings in three ways,normal land preparation method,afforestation by water-harvesting and afforestation by mycorrhizal fungi inoculation.From 2014 to 2017,seedling survival rate,growth and soil water index were observed and measured,and evaluated the drought resistance of different afforestation techniques by subordinate function value.The results show that during 2014-2017,mycorrhizal fungi inoculation could obviously improve the survival rate,growth and soil water index compared with the other two afforestation methods.Combined the afforestation by water-harvesting and mycorrhizal fungi inoculation,indexes were better than other three afforestation methods.In addition,drought resistance evaluation of different afforestation methods ranged from high to low:afforestation by water-harvesting and mycorrhizal fungi inoculation＞mycorrhizal fungi inoculation＞water-harvesting＞normal land preparation method.
