Now that the cold dew has passed for several days, the temperature in various places is gradually dropping, like some cold areas have frost in the morning, so for friends who grow sweet potatoes and green onions, one of the most concerned questions is when to harvest? Another is how to store after harvest? Of course, there are also some families who do not grow their own and buy some in the late autumn and early winter to preserve. So, when exactly is the best time to harvest green onions and sweet potatoes? And how do you store it? Today, I will share my years of experience in preserving sweet potatoes and green onions for your reference.
When to harvest the green onions
The green onions referred to here are winter storage green onions based on edible green onions, and the harvest time varies with the climate and temperature of various places. It depends on the local temperature. If the harvest is early, the green onion leaves and green onion white will continue to grow, which will lead to a decrease in yield, and if the harvest is late, the green onion white will lose water and become soft and empty, which will also affect the yield and quality. In general, the Northeast and Northwest regions are in the period from the autumn equinox to the cold dew, and the North China region is around the time of the cold dew to the frost fall. In other words, when the average temperature of the day drops to about 10 degrees Celsius, the growth of green onions has basically stopped, and it is a good time to harvest.
How to store green onions after harvesting
1. Vertical placement
After the green onion is harvested, due to the excessive moisture, if it is stored immediately it is easy to lead to rot, it needs to be dried for a few days, let the outside dry a little, and then five or six trees are bundled, after the bundling, find a cool, airy and dry place, and place the green onion upright, or the root is placed upright, when the temperature is high, you can take it away and dry it after a few days, and then put it upright. In winter, when the temperature is too low, you can find something to cover it, as long as it is not frostbitten, so that it is generally stored until the Spring Festival.
2. False implantation
Fake planting method to preserve green onions is especially suitable for indoor preservation, like the average family will not save too much, then you can fake plant green onions into pots or other containers. To put it simply, it is to find a larger flower pot, or foam box, etc., fill the bottom of the pot with a layer of soil or river sand, put the green onion root down and place it in the pot, and then fill in a little soil or river sand after the placement, so as not to let the green onion lodging. If the soil is too dry, you can water less water after transplanting, keep the soil moist, and then put it indoors. If you save it this way, the green onions will continue to grow and will not rot until spring.
When are sweet potatoes harvested
Sweet potato harvest time has a great impact on yield and quality, the northern region is generally harvested in the first frost, that is, around October, and some places in the south are harvested in November, and the specific harvest time needs to be determined according to the growth and temperature changes. Generally, the average temperature should not be lower than 10 degrees, and if it is lower than 10 degrees, it is easy to freeze damage.
How to store sweet potatoes
In fact, the preservation of sweet potatoes is very simple, the older ones know, in the sixties and seventies, at that time, many areas took sweet potatoes as a staple food, every family will save thousands of pounds of sweet potatoes, there are cellars stored in the cellar, there is no cellar, at that time every family in the countryside has a kang, put the sweet potatoes on one end of the kang, and cover the surrounding and above with soybean leaves or leaves, and can be eaten until the spring of the year. And now that there are fewer cellars and no more ondols, how should they be preserved?
Now there are generally not as many as before, such as home preservation of sweet potatoes, you can find a few cartons, select the sweet potatoes that are not damaged, put them in a carton, and then put them in a warm place indoors, and you can find something to cover it when it is cold. Because sweet potatoes are afraid of cold and not afraid of heat, pay attention to the temperature should not be too low when storing, not lower than 12 degrees, and the temperature of storing sweet potatoes is required to be more than 12. Again, sweet potatoes are afraid of cool breezes, so they should be kept away from doors and windows when placed indoors.
