Due to its growth characteristics, green onions can be divided into autumn onions, summer onions and spring onions depending on the season of planting. The sowing time of different seasons of onions is different. The following is a brief introduction of the sowing time and growth management of different seasons of green onions.
First, planting time
Spring onions: The sowing time of spring onions usually depends on the defrosting of the soil. The suggestion here is to sow immediately after thawing so that it can be harvested before the summer.
Summer onions: Sowing time for summer onions is generally between the end of July and the beginning of August each year, because it is within three volts, so this season's onions are often called scallion.
Autumn onions: The sowing time of autumn onions is generally selected at the beginning or middle of September each year. Because the temperature is low at this time, it usually takes a second year of growth before it can be marketed.
Second, growth management
1, soil quality
The growth of green onions still has certain requirements on the soil, such as the soil is loose, and the fertility is sufficient. Not only that, the soil needs to maintain a certain humidity at all times, but in the seedling stage, in order to prevent the problem of the onion, it is necessary to control the surface soil, so we should pay attention to the drainage capacity when selecting the soil.
2, temperature
Green onions are crops that are relatively tolerant to low temperatures, so the temperature requirements are not high. However, in the seedling stage, it is necessary to pay attention to maintaining a certain ground temperature, otherwise it is easy to frostbite. And some green onion varieties are not resistant to high temperatures, and the high quality environment tends to cause such onions to be of poor quality and low selling price. So try to understand the varieties of onions in advance and keep a reasonable temperature.
3, moisture
Green onions are good water crops, so it is better to grow in areas with high depreciation. Therefore, we can water more during the growth period of the green onion, but pay attention to the shallow pouring, only need to let the surface soil wet. Rainy areas should pay attention to drainage, reduce watering, and avoid the occurrence of decay of roots of green onions.
4, lighting
Green onions are not very light-sensitive, and usually only need to maintain medium-intensity light.
5, nutrients
In the process of planting green onions, fertilizers such as nitrogen, phosphorus and potassium are needed to provide nutrients. For some trace elements, they can also be provided by the land itself.
