红枣营养丰富,含有糖、蛋白质,铁、钙、维生素等成份,有较高的经济价值。我国河北、山东、河南、陕西、甘肃、山西等地枣树最多,栽培历史也很悠久。2000多年前撰成的我国第一部记传体通史《史记》中就有“安邑千树枣”的记载(安邑在山西省运城县境内),可见当时栽培枣树之盛。稷山县是我国红枣的主要产区之一,这里生产的板枣品种优良,含糖量高达71.5％,畅销国内外。但是,多年来红枣生产中的重要技术问题——快速干制,一直没有得到解决。每到红枣收获季节,常因绵绵秋雨,造成大量霉烂,离晾枣棚很远的地方就可闻到酸臭的烂枣味。1975年仅稷山县桃村大队就烂掉鲜枣25万多斤,烂枣率高达50％以上,损失6万余元。群众看着一堆堆烂 Jujube nutritious, containing sugar, protein, iron, calcium, vitamins and other ingredients, have a higher economic value. China’s Hebei, Shandong, Henan, Shaanxi, Gansu, Shanxi and other places most jujube, cultivation history is also very long. The record of “An Yi Chizhu jujube” (Anyi City in Yuncheng County, Shanxi Province), which was written more than 2,000 years ago in China, the first general biography and biography history in China, shows the flourishing date tree at that time. Jishan County is one of the main producing areas of Chinese jujube. The varieties of jujube produced here are of excellent quality and the sugar content reaches as high as 71.5%, which are sold both at home and abroad. However, the important technical issue in jujube production over the years - rapid drying has never been solved. Every jujube harvest season, often due to cotton rain, resulting in a large number of rotten, far away from the drying date shed can smell sour rotten taste. In 1975 alone Jashan County Taocun brigade rotten 250,000 kilograms of fresh dates, rotten dates as high as 50% or more, the loss of 60,000 yuan. The crowd looked piles of rotten
