近年来,采用草帘和聚乙烯薄膜配合覆盖冻藏堆,提高保藏效果,取得了显著地经济效益。但是,由于草帘既是易燃物,又怕雨湿,并且年耗损量大,且不利于安全防火。而珍珠岩具有防寒、保温隔热的作用,为此特于1982/83和1983/84两个制糖期,进行利用膨胀珍珠岩配合草帘和聚乙烯薄膜覆盖甜菜冻藏保管堆的捂冻效果试验观察。现将试验结果介绍如下。
In recent years, the use of straw curtain and polyethylene film with frozen piled heap to improve the preservation effect, and achieved significant economic benefits. However, since straw curtains are both flammable materials, they are afraid of rain and wetness, and consume a large amount of annuals, and are not conducive to safety and fire protection. The perlite has a cold, thermal insulation effect, especially for the 1982/83 and 1983/84 two sugar period, the use of expanded perlite with straw curtain and polyethylene film covering the custody of sugar beet frozen Effect test observation. Now the test results are as follows.
