Whether it is frozen or refrigerated depends mainly on personal needs. If it needs to be preserved for a short time, it will be refrigerated. If it needs to be preserved for a long time, it should be frozen. Generally, the temperature of cold storage is about 4- 15 degrees Celsius, which has little effect on the freshness of corn, so the freshness of corn can be kept to the maximum in a short time. As long as it is kept at about 1 week, it is recommended to put it into cold storage.
The temperature in the freezing room is below 0℃, which has the greatest influence on the taste and nutritional components of corn, but it can also inhibit the growth and reproduction of bacteria, so it needs to be preserved for several months, so you can choose to freeze it. Peel the corn before freezing. There is no need to peel off all the skins. Leaving a little skin can keep the corn fresh for a long time.
growing environment
Corn likes light and is not tolerant of shade, so it is a short-day plant. Corn likes temperature, the suitable growth temperature is 22-30℃, the seed germination temperature is 6- 10℃, the jointing stage temperature is 15-27℃, the flowering temperature is 25-26℃, and the filling temperature is 20-24℃.
Corn is a thermophilic crop, which needs higher temperature during the whole growing period. The biologically effective temperature of maize is 65438 00℃. Seed germination needs 6- 10℃, which is slower than 10℃, and 16-2 1℃ has strong vitality. The optimum temperature for germination is 28-35℃, and the germination is stopped above 40℃. The seedling stage can withstand short-term low temperature of -2 ~ 3℃. It needs 15-27℃ at jointing stage and 25-26℃ at flowering stage.
