Cultivation techniques of shallot
Small shallots, also known as shallots and chopped shallots, are tender in texture and rich in fragrance. They can be planted all year round, but spring and autumn are the best.
Small shallots have strong cold resistance and high temperature resistance. Like green onions, they all like cold environment. The seeds of shallot can germinate when the ground temperature is about 5℃, and the suitable temperature for its germination is about 12℃ and 13℃.
The temperature in spring and autumn is relatively small for shallots to grow and develop. The shallots in this period grow with delicate taste and better quality. So, how is the rural chives planted? Let's take a look at it:
First, seed selection
The seeds of shallots are very small, so it is best to treat them before planting. You can soak them in warm water for 2 to 3 hours and dry them for later use. It can not only sterilize the seeds, but also accelerate the germination and emergence of the seeds.
We should choose fine varieties suitable for local growth characteristics, because it has strong adaptability and can be planted in general land. But it is best to choose soil with deep soil, loose and fertile soil and good air permeability. The shallots can be broadcast directly, or it is feasible to raise seedlings and transplant them.
Second, raise seedlings.
In the selected plots, we should dig deep, and apply organic fertilizer combined with appropriate amount of chemical fertilizer to meet the growth needs. It is best to choose plots where onions and garlic have not been planted for two or three years to avoid the aggravation of pests and diseases.
Third, fix seedlings.
Generally speaking, when shallots grow to about 15 cm, they can be transplanted and planted when they grow 2-3 leaves.
After planting, planting water should be poured in time in order to provide enough water for the seedlings to grow better and improve their survival rate.
Because the root distribution of shallot is shallow and the root absorption capacity is not good, we should pay special attention to water management. It is best to drip irrigation with small water instead of flooding irrigation with large water. Generally, water can be poured once a week.
The growth of shallots also needs nutrients, because there is a base fertilizer, so an appropriate amount of urea should be applied in combination with watering to avoid burning the roots.
Fourth, pest control.
Like other onion crops, shallot will be harmed by diseases and insect pests during its growth. Such as leaf blight and anthrax, once the disease occurs, it must be controlled by drugs in time.
On the issue of pest control, it is best to give priority to prevention and combine prevention with control, because once the disease occurs, no matter how good the medicine is, it will have side effects and affect the growth and development of crops.
Fifthly, harvesting.
When the seedlings grow to more than 30 centimeters, they can be harvested under normal circumstances. The harvest of shallots is usually carried out in sunny morning or evening.
In a word, chives are rich in nutrition and the planting area is expanding day by day. Only by mastering its planting techniques can we plant high-quality and high-yield chives.
