Fruit and vegetable preservative

Abstract

The invention discloses a fruit and vegetable preservative. The fruit and vegetable preservative comprises the active ingredients of prochloraz and thidiazuron, wherein prochloraz is a prochloraz active compound or prochloraz manganese salt or prochloraz copper salt, prochloraz accounts for 10wt%-70wt% of the fruit and vegetable preservative, thidiazuron accounts for 0.02wt%-5wt% of the fruit and vegetable preservative, the balance of auxiliary components which are allowable to use and acceptable in farm chemicals is complemented, and the weight ratio of prochloraz to thidiazuron is (5-500):1. The fruit and vegetable preservative disclosed by the invention can be prepared into a suspending agent, a suspoemulsion, wettable powder and water dispersable granules by known methods. The fruit and vegetable preservative disclosed by the invention is used for storage and preservation of vegetables and fruits after harvesting by complexing prochloraz and thidiazuron, has good mildew-proof and sterilization effects for the vegetables and the fruits, can prolong the storage period of the vegetables and the fruits, realize a prominent green-retaining effect and ensure the storage quality of the vegetables and the fruits, has no chemical residues, and is safe and convenient to use, low in cost and easy to operate and popularize.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping, and in particular relates to a fresh-keeping agent for fruits and vegetables. Background technique [0002] The seasonality of fruit and vegetable production is strong, and the harvest period is relatively concentrated. Most of the fruit and vegetable products have high water content, soft tissue, and are not resistant to storage and transportation. After fruits and vegetables are picked, affected by respiration and transpiration, nutrients and water are easily consumed and lost, and the quality, flavor and appearance deteriorate, and they are also easily infected by harmful organisms such as bacteria and molds. However, there are many links from production to sales of fruit and vegetable products. If the post-harvest treatment of fruits and vegetables is not paid attention to, a large amount of losses will often be caused during the circulation and transportation of fruit and vegetable pro...
