How to grow dried onions

Spring onions are the ingredients we often use, with tender green leaves and white onions, which can add flavor to the dishes. Usually we buy home onions, onions are easy to dry, so, how to grow dried onions?

First, how to grow dried onions?

Prepare a medium-sized flowerpot and choose loose and fertile soil to put into the pot. Prepare the onions, remove the outer layer of the onions, insert the onions directly into the flowerpot and water them thoroughly, and place the balcony for maintenance. Usually pay attention to keep the soil moist, about a week or so will see the green buds grow out.

Second, what are the growth habits of onions?

The adaptability of spring onion is strong, which is mainly affected by temperature, moisture, light, climate, soil, fertilizer and so on.

1. Temperature

Spring onion originated in the semi-cold zone, has a wide range of adaptation to temperature, likes cold and cold and is not resistant to hot, and can obtain better yield and quality under cold and warm conditions. The most suitable temperature range for green onion growth is 13-25 ℃, the highest temperature can withstand 45 ℃, the cold resistance of spring onion is strong, and the lowest tolerance is-20 ℃. The vernalization temperature is 2-7 ℃, and the time to complete vernalization is 7-10 days.

two。 Moisture content

Spring onion has the growth characteristics of drought tolerance and not waterlogging tolerance. Spring onion leaves are tubular and waxy on the surface, which can effectively reduce water evaporation and play a role in water conservation and drought resistance. Although spring onions are resistant to drought and waterlogging, because of their short roots and poor water absorption capacity, they should be irrigated and drained in time in each growing period, especially in the years with more Rain Water, and the stagnant water in the field should be eliminated in time to avoid too much water in the field for too long, resulting in retting and rotting roots. Therefore, attention should be paid to the appropriate moisture environment to meet the needs of plant growth and avoid the lack of water or excessive water affecting good growth.

3. Light

Spring onion is a crop that is not tolerant to shade and does not like strong light, and the requirement for light intensity is moderate. After normal vernalization, light intensity and light time can grow and blossom normally. In each growing period of onion, suitable light conditions can promote plant growth, make onion white and sturdy, and increase yield.

4. Soil

Spring onion has strong adaptability to soil, and is suitable for planting in the soil with pH value between 6.9 and 7.6, but because of its short root system, small root group and underdeveloped, it is suitable to choose the land with fertile soil, deep soil layer, suitable light and good drainage and irrigation. If the pH value of soil is too high or too low, it will hinder seed germination and affect the normal growth of onions.

5. Fertilizer

Spring onions like fertilizer, especially the demand for nitrogen element is large, sufficient nitrogen fertilizer can effectively improve the yield and quality of onions. Followed by potassium, phosphorus, calcium, magnesium, boron, manganese and other nutrient elements. The amount of nitrogen and potassium absorbed in the peak growth period is about 1RU 0.9; the absorption amount of N and K in the leaf sheath stage is about 1Ru 1.2; the largest amount of phosphorus is needed in the seedling stage, which meets the supply of phosphate fertilizer at this stage, which can ensure that the spring onion seedlings are healthy, grow vigorously, and achieve growth and income.

Whether it is planting with dried onions or seeds, it is easier to cultivate onion leaves by mastering its growth habits.
