Old leek has been transplanted for several months.

The old leek is generally transplanted from late July to mid-August, and should be completed before the Mid-Autumn Festival, and if the leek is very thin and short, it can be transplanted in the early spring of the following year. Old chives generally adopt the method of deep trench transplanting, pay attention to seedling emergence and planting density, and should also repair border drainage and irrigation to do a good job of field management.

First, the old leek has been transplanted for several months.

It is better to transplant old leek before the Mid-Autumn Festival from July 20 to August 15. If the leek is relatively thin and short, it can be transplanted in the early spring of the following year. Transplanting should be avoided in winter. If the leek is not planted in summer, it can be transplanted when it grows to 18-20 cm.

2. Transplanting methods of old leek

1. Deep trench transplanting

Old leek transplanting, generally use a single row of deep trench transplanting, ditch planting can be with the growth of the plant, continue to cultivate the soil, between the rows into a deep trench, before planting the soil thoroughly, as much water as possible, and then dig out the leek, remove the front end of the root, leaving 2-3 cm long roots, and should be cut off 2/3 of the leaves. Dig a deep trench with a row spacing of 40 cm and a depth of 15 cm, and then plant seedlings at a distance of 1-1.5 cm per plant.

2. Seedling emergence and planting

The seedlings should be raised 3 days before planting, and a small amount of water should be poured before the seedlings to prevent root damage, and the thin seedlings in the leek seedlings should be removed. The number of seedlings should be planted on the same day, and if it is not well planted on the same day, it must be completed within the next day.

The planting density of leek should be reasonably close planting, if the density is too low, it will affect the yield, if the density is too high, then affect the quality, generally have strong tillering ability of leek, and plant shape loose varieties, should not be too close planting. If the tillering ability is weak and the plant type is erect, it can be planted closely.

3. Border repair, drainage and irrigation

Transplanting leek should pay attention to the soil that is easy to drain and irrigate, because leek is afraid of flood, and deep ploughing should be carried out before planting, which can make the soil soft, hold the ground flat and build a ridge on the border surface. If the cultivation is in the south, because there are too many Rain Water, high wow cultivation is needed. If there is less Rain Water in the north, it is suitable for flat bed cultivation. The method of flat bed cultivation is 2-3 plants per clump, generally 25-30 cm between rows and 7-10 cm between clumps.

4. Field management

When burying the soil, the depth of the soil can not cover the lobular nodes. After planting, it should be watered twice in a row, and the soil should be thinned in time. When the leek grows to 15 centimeters, it should be fertilized once, and then fertilized again after 20 days. Watering should be controlled after the beginning of autumn, and watering before freezing should be paid attention to in winter.

Leeks have high requirements for fertilizer, they should use sufficient nitrogen and phosphorus fertilizer, and enough organic base fertilizer should be used before planting. After using organic fertilizer, remember to turn the soil and mix the fertilizer with the soil evenly. If it is not the manure used, but straw compost, diammonium phosphate can be used as supplement.
