Chestnut is afraid of heat, fear of dryness, fear of freezing, and fear of wetness. Although there are many storage methods, slight weight loss, germination and mildew deterioration will occur. Relevant measures must be taken to reduce losses and extend the shelf life. Mild and rotten corruption. The chestnut mold is mostly infected by Rhizopus spp. or Mucor sp. It is related to the disease resistance, maturity of harvesting and environmental conditions of the species. The prevention measures include: 1. Harvesting timely. Must be harvested after chestnuts have matured sufficiently to increase their disease resistance. 2. Strengthen ventilation management. Lowering the temperature appropriately to create a suitable low-temperature condition can reduce the chestnut fruit's respiration, reduce metabolism, and prevent deterioration of the mold. 3. Adding a certain amount of pine needles in the sand, basket racks, and freezer bags can inhibit mold growth. 4. Rapidly cool the newly harvested chestnut to reduce the chestnut fruit to less than 5°C. Not only can mold be avoided, mildew can be reduced, but also the storage period can be extended. Lose weight and air dry. The weight loss of Chinese chestnuts is mainly due to the low humidity and high temperature in the storage environment. The prevention method is to increase the humidity in the storage environment and reduce the storage temperature. Such as the sand regularly humidified; cold storage before washing with water, do not dry packing; using film bags and so on. Increasing the relative humidity of the warehouse and reducing the amount of ventilation is also an effective method. Prevent germination. Chestnut sprouting conditions are higher humidity and suitable temperature, to prevent its germination measures are: 1. Drug treatment. Using 0.1% longer than the time, or Qingshui or naphthalene acid dipping fruit, can inhibit the chestnut germination. It can also be prevented by waxing. 2. Saline treatment. When chestnuts are about to germinate 30 to 50 days later, they are soaked in a mixed solution of 2% salt and 2% soda ash for 1 minute. They can be stored in baskets or sacks before being dried, and then put in some pine needles to suppress germination. 3. Carbon dioxide treatment. Before germination, filling the film bag with 5% of carbon dioxide and 3% to 5% of nitrogen can effectively inhibit chestnut germination. Pest control. Chestnut is often rotted due to bruises such as chestnut weevil during storage. Can be used 40 ~ 60 g / cubic meter of bromide fumigation, processing time 3.5 to 10 hours. Or close treatment with 50 mg/L carbon disulfide for 18 to 24 hours. Smoke Alarms,Smoke Detector,Smart Smoke Detector,Ring Smoke Detector Guangdong Isafenest Co.,Ltd. , https://www.isfenest.com
