随着人们物质文化生活水平的提高,种植花草树木已成为千家万户的迫切需要。花木的邮售不仅弥补了地区限制、品种残缺的不足,亦可满足爱好者求异求新的需要。然而,笔者在多年的购花实践中认为邮售花木存在以下几个问题需要探讨。一、邮寄中的温度。邮售花木一般从经济角度出发,根本没有调温设备,在邮途中只能靠自然温度调节。因此,在得不到养分补充的情况下,我认为减缓其体内养分的消耗是保持其较强抗逆性和生理机能的有效方法。花木的邮寄是短期贮藏过程,邮寄温度可适当偏离其最适温度,以降低花木的自身消耗。但不能超过其极限温度。温度偏高,花木呼吸作用快,不耐贮藏。特别是有的花木受过病、虫害侵染,加上采挖、修剪、包装、邮途中受到机械损伤,在特殊的温度、湿度、空气等条件下病虫害就发展、蔓延,从而带来较大的损失。例如:笔者1992年 With the improvement of people’s material and cultural life, planting flowers, trees and trees has become an urgent need for every household. The sale of flowers and trees not only makes up for the lack of regional restrictions and varieties, but also meets the needs of lovers seeking new ones. However, in my many years of practice of purchasing flowers, I think the following problems need to be discussed in the postal sale of flowers and trees. First, the temperature in the mail. Post sales flowers and trees generally from an economic point of view, there is no temperature control equipment, mail only by natural temperature regulation. Therefore, in the absence of nutrient replenishment, I think reducing the consumption of nutrients in the body is an effective way to maintain its strong resistance and physiological function. Tile mailing is a short-term storage process, mailing temperature can be deviated from its optimum temperature, in order to reduce their own consumption of flowers and trees. But can not exceed its limit temperature. High temperature, flowers and trees fast breathing, intolerance storage. In particular, some flowers and trees suffer from disease and pest infestation, coupled with excavation, pruning, packaging, mail mechanical damage, under special conditions of temperature, humidity, air and other pests and diseases on the development and spread, resulting in larger loss.
