Onion storage methods

Onion is a perennial herb of Liliaceae. The main edible part is bulb, the meat is fresh and sweet, and the nutritional value is rich. It belongs to a kind of main vegetable in our country, and its planting area is also relatively large. After the onion is ripe and harvested, if it can not be put on the market in time, then it needs to be stored well. So how do you store onions? The following editor has brought you the storage method of onions, let's have a look!

1. Indoor storage

After the onion is harvested, wash the soil from the bulb and dry it until the onion skin dries gradually. Another part of the pseudostem and leaves were removed. Choose high-quality onions to remove bad onions such as disease spots and insect eyes to ensure that the stored onions meet the storage standards. Then put the onions into the net stack, and then put the net stack in a ventilated room, which should be kept dry. Hide it to a height of about 90 centimeters and turn it every half a month or so. When the temperature gradually drops, you can stop turning the heap, if the temperature is too low, then you should also do a good job of covering and anti-freezing.

2. Outdoor storage

If it is stored outdoors, then we must first choose the storage plot. The land should be in a place where it is dry, drained and irrigated normally and can be protected from wind and light. Eat bamboo poles or wood mats on the ground, and then spread a layer of grain straw or fodder on the bamboo. Then stack the onions that need to be stored on it, keep the height of the storage at about 1.6 meters, and do a good job of sun and rain protection. Because the onion moisture is more, so if the temperature and humidity is larger, then every 10 days or so to turn the pile properly, otherwise easy to heat retting. Then turn every 2-3 weeks, according to the climate, hot and humid conditions to control the number of times and time.

3. Hanging and hiding method

Hanging storage is also a common storage method for onion storage. Use string to weave the harvested and dried onions into a braided shape. Then use bamboo and wood to build a horizontal frame indoors, and then hang the onions directly on the horizontal frame. Hanging storage is conducive to ventilation during storage, and easy to check, can reduce decay. This storage method is suitable for producing areas with small planting area and low yield. When hanging and storing, we should pay attention to control the temperature, and keep the lowest temperature above minus three degrees Celsius. If the temperature is too low, then do a good job of heat preservation.

The above is a brief introduction to the storage methods of onions. In addition to the above storage methods, controlled atmosphere storage and cold storage are the main storage methods of onions. We should choose reasonable storage methods according to planting area and yield to ensure planting efficiency. That's all for today's introduction. This article is for reference only.
