Introduction: Approximately 33 million natural Christmas trees were used in the U.S. in 1998. Given a conservative wholesale value of $10.00 per tree, the value of the trees alone approaches $330 million. When associated products are added to the picture, total value is well above $0.5 billion. The National Christmas Tree Association estimates the average retail price for Christmas trees in 1998 at $3.45 to $6.30 per ft. Based on a standard 6to 7-ft tall (2 m) tree, the retail value of natural Christmas trees approaches $1.5 billion. About 25% of the live Christmas trees consumed in the U.S. are sold on Choose-N-Cut farms. This means that 75% of the trees experience some form of storage and shipment after harvest. Storage and shipment times can be several weeks for trees shipped between countries, or less than one day for trees sold in local markets. Natural Christmas trees quickly lose quality if handled improperly. People who grow, sell, handle or use Christmas trees should know something about tree keepability. This is true of the consumer who may use only one tree each year, as well as brokers or growers who handle thousands of trees. Many publications have been written concerning postharvest physiology, handling and keepability of Christmas trees. Despite this, there is often ignorance of the subject, resulting wasted trees, reduced tree quality, erroneous information or dissatisfied consumers. In this article, we provide a summary of information concerning Christmas tree keepability.
简介:1998年，美国大约使用了3300万棵天然圣诞树。按照每棵树10美元的保守批发价计算，光是这些树的价值就接近3.3亿美元。如果加上相关产品，总价值将远远超过5亿美元。美国国家圣诞树协会估计，1998年圣诞树的平均零售价为每英尺3.45美元至6.30美元。以一棵标准的6至7英尺高(2米)的树为基础，天然圣诞树的零售价值接近15亿美元。在美国消费的活圣诞树中，约有25%是在“选择- n - cut”农场出售的。这意味着75%的树木在收获后会经历某种形式的储存和运输。在国家之间运输的树木可能需要数周的储存和运输时间，而在当地市场销售的树木则不到一天。如果处理不当，天然圣诞树很快就会失去质量。种植、销售、处理或使用圣诞树的人应该了解树木的可持续性。对于每年可能只使用一棵树的消费者，以及处理数千棵树的经纪人或种植者来说，都是如此。许多出版物已经写了关于采伐后的生理学，处理和保存圣诞树。尽管如此，人们往往对这一主题一无所知，导致树木被浪费，树木质量下降，信息错误或消费者不满意。在这篇文章中，我们提供了一个关于圣诞树可保存性的信息摘要。
