根据《江西省第二次土壤普查技术规程》提出的“六统一”技术标准要求,其中统一取样方法要求整段标本按土种采取,以备将来进行土种鉴比和进入陈列馆作为培训班的实物标本讲解,提高广大干群认土、用土的科学知识。过去制作整段土壤标本,一般都是用木盒厚层法,这种标本造价较高,而且笨重,不易运输保存。这里介绍的木板胶、粘法是在华东师范大学陈家琏同志研制的基础上进行改革而成的。用这种方法制作的土壤整段标本,同木盒厚层土壤剖面标本一样,可把野外模式搬到室内来,能真实地反映土壤剖面整段性状和土体原有构型,有利于观察土壤颜色、性
According to the requirements of the “six unified” technical standards proposed in the “Technical Regulations for the Second Soil Census of Jiangxi Province”, the unified sampling method requires that the entire sample should be taken according to soil type in preparation for the future assessment of soil type and access to the exhibition hall as a training course Of the physical specimen to explain, improve the vast majority of cadres to recognize soil, earth with scientific knowledge. Past production of the entire soil samples are generally thick wooden box method, the higher cost of such specimens, and bulky, not easy to transport preservation. The wood glue and sticking method introduced here are made on the basis of the research and development made by Comrade Chen Jiaxiong of East China Normal University. In this way, the entire soil sample, like the thick-walled soil profile samples of wooden box, can be used to move the field pattern to the interior and truly reflect the whole section of the soil profile and the original configuration of the soil so as to be observed Soil color, sex
