How to store pears in spring? Four methods to help you extend their shelf life

I. Chemical fumigation method. The fumigation method mainly prevents and controls diseases that invade the fruit. First, seal the pears with plastic film, then place a fumigant (such as acetaldehyde) inside the sealed plastic film so that the fumigant concentration inside the plastic film reaches 0.5% and is maintained for 180 minutes, or so that the fumigant concentration inside the plastic film reaches 1% and is maintained for 120 minutes.

II. Medicinal solution soaking method. This method mainly prevents pears from being infected by pathogens after harvest. Soak the pears in a 400-fold dilution of 4% Nongkang 120 fruit tree-specific solution for 50 minutes, then remove and air-dry, then package and store.

III. Calcium enrichment treatment method. Soak the pear fruit in a 1%-5% calcium chloride solution for 1-5 minutes. According to experts, calcium enrichment can inhibit the respiration of pears, reduce ethylene production, and reduce the occurrence of black heart disease in Ya pears and red flesh disease in Xuehua pears. At the same time, it can also improve the resistance of pears to carbon dioxide and improve the storage effect.

IV. Coating treatment method. Apply a fruit-specific coating agent to the surface of the pears, and after the coating agent dries, a thin film forms. This film can, to a certain extent, hinder gas exchange and water evaporation of the fruit, improving the storage effect.
