全地下自然通风果品贮藏库是我国传统的贮藏方式之一,它具有投资少、不耗电、易建造、管理简单、贮藏效果好等优点,非常适合我国的国情,是许多水果产区的主要贮藏手段之一。“六五”期间,国家曾拨款在河北、山东及辽宁等地建造了上千座大型自然通风库,由于当时对果品库热工环境缺少系统深入的研究,建库时无据可依,单凭经验进行,大部分库建成后均存在通风不良、贮藏初期库温过高,果品腐烂严重,致使大部分库弃用。同时也限制了这一贮藏技术的进一步推广应 The whole underground natural ventilation fruit storage is one of the traditional storage methods in our country. It has the advantages of less investment, no power consumption, easy construction, simple management and good storage effect, which is very suitable for the national conditions of our country and is the main part of many fruit producing areas One of the means of storage. During the period of the Sixth Five-Year Plan, the state has allocated thousands of large-scale natural ventilation reservoirs in Hebei, Shandong and Liaoning. Due to the lack of systematic and deep research on the thermal environment of the fruit store at the time, Based on experience, most of the warehouses have poor ventilation after they are built. The storehouse temperature is too high in early storage, and the decay of the fruits is serious, resulting in the abandonment of most of the warehouses. It also limits the further promotion of this storage technology
