黑龙江省位于全国的最北部,冬季最低气温达—40℃以下。蔬菜季节性生产同长年消费的矛盾极为突出,冬春淡季达七个多月,冬春两季城市居民所需要的蔬菜,主要靠秋菜贮藏来解决。目前,全省大、中城市商业菜库,每冬都要贮藏上亿斤蔬菜,以保证淡季市场供应和平抑物价。但是由于蔬菜贮藏期长,防冻问题一直没有得到彻底解决,因此每年都有几百万斤蔬菜遭受冻害损失。在菜库应用推广了远红外线辐射升温机后,蔬菜的冻害问题才宣告 Heilongjiang Province is located in the northernmost part of the country, and the minimum winter temperature is below -40°C. The contradiction between seasonal vegetable production and long-term consumption is extremely prominent. The winter and spring off-season reaches more than seven months. The vegetables needed by urban residents in winter and spring are mainly determined by the storage of autumn vegetables. At present, the large and medium-sized cities in the province’s commercial vegetable banks store billions of kilograms of vegetables every winter to ensure that the market supply in the off-season can be kept at a level that suppresses prices. However, due to the long shelf life of vegetables, the problem of antifreeze has not been completely solved, so millions of kilograms of vegetables are lost every year due to freezing damage. After the application of the far-infrared radiation heating machine in the vegetable store, the problem of freezing injury of vegetables was announced.
