When is the best time to plant chives (planting and transplanting methods and time of broad-leaf chives)

Chives are a very common vegetable in our lives, and they are quite delicious when eaten with fried eggs.

It is not expensive in the market and is rich in nutrition, so many people buy it, especially broad-leaf leek, which has a good taste and can be fried or used as stuffing.

At present, the prospects of growing chives are good and profitable. So when is the best time to plant chives? Let me tell you.

When is the best time to plant chives?

Chives can be planted in spring, summer and autumn, but the best time is between March and May in spring .

At this time, the climate is conducive to growth, it can germinate quickly, and management is also easier. If the temperature can be well controlled, it can be planted in all seasons.

It is recommended to germinate the seeds before planting. Soak them in warm water and wait for the radicle to extend before sowing. Sow them by broadcasting and cover with a thin layer of soil. Water them appropriately and cover them with plastic film to keep them warm and moist. Seedlings will emerge soon.

2. What are the environmental requirements for growing leeks?

1. Temperature

Leek is cold-resistant but not heat-resistant, and has a wide temperature adaptability range. The optimum temperature for germination is 15-18℃, and the optimum temperature for growth is 15--25℃.

2. Lighting

The light intensity is moderate, and it has the ability to tolerate weak light. Leeks are relatively shade-tolerant, and the growth of leaves requires moderate light intensity. Too strong or too weak light will affect the quality and yield of leeks.

Chives are long-day plants. The plants that have undergone vernalization pass through the light stage under long-day conditions, and bolting, flowering and fruiting also require a longer number of daylight hours.

3. Moisture

The growth of leeks requires lower air humidity, generally 60%-70%, and higher soil humidity, generally 80%-95%. Therefore, sufficient water should be supplied during cultivation to keep the soil moist.

4. Soil and nutrition

Leek has a strong adaptability to soil and can be cultivated on sandy loam and clay, but it is best to grow in soil with a deep soil layer, rich in organic matter, and strong water retention. Leek has a certain adaptability to saline-alkali soil, and mature plants can grow normally in soil with a salt content of 0.25%.

Leek likes fertilizer and tolerates fertilizer, so it requires sufficient basal fertilizer during cultivation. In spring and autumn, topdressing should be done in stages, mainly nitrogen fertilizer, with phosphorus and potassium fertilizer, which will help increase yield and improve quality.

Leek planting technology

1. Seedling cultivation

After sowing, keep the soil moist, water lightly once when the seedlings are about 5 cm tall, and loosen the soil in time. After 10 cm, you can combine watering with topdressing with decomposed manure or urea 2-3 times, and flush with water with crystal trichlorfon 0.5-1 kg per mu to kill pests such as leek maggots.

When the seedlings are 15 cm tall, control irrigation to prevent them from growing too tall and falling over. Weeds should be removed in time. When the seedlings are about 12 cm tall, use 0.5-0.75 kg of 25% herbicide per mu to prevent weeds.

Or after sowing and before seedlings emerge, spray 0.15 kg of 33% herbicide emulsion per mu to treat the surface. The seed rate per mu of field is 0.5 kg.

2. Planting

Choose a plot of land with loose, fertile soil and convenient irrigation and drainage. Leek is a fertilizer-tolerant vegetable, and applying sufficient base fertilizer is one of the important measures to make leeks grow tall and thick and produce high yields.

Apply 1500-2000 kg of decomposed farmyard manure per mu, add appropriate amount of phosphorus fertilizer, level the land and make ridges. The ridge width is 2-3 meters. Transplant in late June to early July. Apply base fertilizer into the planting ditch.

Before planting, cut off the ends of the fibrous roots of the chives and arrange them into small bunches even with the bulbs. Plant in flat beds with a row spacing of 50 cm and a hole spacing of 16-26 cm. It is appropriate to plant 6-8 plants in each hole. When planting, it is best not to bury the leaf sheaths. After planting, tamp down the soil and water in time.

3. Field management

When the new leaves of leek are out, water should be poured to slow down the seedling growth, and inter-cultivation should be carried out to conserve moisture, so as to keep the soil dry and moist. After the fall, when leek grows most vigorously, it is necessary to fully supply fertilizer and water.

Later, the temperature gradually decreases, the plant grows slowly, and the surface of the soil is kept moist. In the year when leeks are planted, the management is mainly to apply fertilizer to promote growth.

4. Harvesting and harvesting

Leeks can be harvested all year round, but it is best to harvest them in the early morning . It is best to cut to the yellow leaf sheath 3-4cm above the bulb.

Each subsequent cutting should be slightly higher than the previous one to ensure normal growth. The yield is low in the first 1-2 years after planting, the 3-6 years are the peak growth period with the highest yield, and it enters the aging stage after 10 years.
