果蔬贮运过程中常常会发生病变腐烂现象,造成贮藏损失。病害发生的种类概括起来可分为2大类:一是由于贮运环境条件不适宜引起的生理病害,如冷害、冻害、气体伤害和药害等;二是由于病原菌侵染引起的侵染性病害。此外还有由于外部机械力及虫害造成的机械损伤。其中尤以侵染性病害造成的损失最为严重,而生理性病害和机械损伤更易加剧侵染性病害的发生和发展,因此均应尽量避免。一、生理病害1、冷害低温通常对果蔬贮运是有利的,但不适宜的
During storage and transportation of fruits and vegetables, diseased rot often occurs, causing storage loss. The types of diseases can be summed up in two broad categories: First, due to improper storage and transportation of environmental conditions caused by physiological diseases, such as chilling injury, frost damage, gas injury and injury; Second, due to infection caused by pathogen infection Diseases. There are also mechanical damage due to external mechanical forces and pests. In particular, the most serious loss caused by infectious diseases, and physiological diseases and mechanical damage more likely to aggravate the occurrence and development of infectious diseases, it should be avoided. First, the physiological diseases 1, chilling injury Low temperature is usually beneficial to the storage of fruits and vegetables, but not suitable
