Leek is a perennial herb of Liliaceae. Leek is cultivated once and harvested for many years. However, with the extension of growth time after planting, the root system of leek will be longer and need to be transplanted. So what are the transplanting methods of leek roots with old roots?
Transplanting time of old root leek root
It is most suitable to transplant leek roots from late June to early July. The transplanting time of leek roots is generally in summer, and it can also be judged by the growth of plants. When the number of leaves is 4 to 5, or the height of the plant is about 17 cm, transplanting should be carried out.
Transplanting method of old root leek root
1, land selection
Because the transplanted leek will not be replanted for 2 13 years as long as it does not weaken, fertile loam should be selected for land selection, fermented farmyard manure should be applied, and deep ploughed into the ground to level the border surface for later use.
In land selection, we should pay attention to the selection of plots where leeks, onions, garlic and green onions have not been planted for three years to prevent the spread of some pests and diseases caused by continuous cropping.
2. Cut the tip of the blade and fibrous root.
After planting leek, in order to reduce water evaporation, most leaves are cut off, while the tip of fibrous roots is cut off, leaving only a small part of stem roots, about 2-3 cm long. This is to promote the development of new roots and dry them in the sun.
Trenches with a depth of 10 to 13 cm shall be excavated according to the predetermined row spacing. If you have plant ash at home, you can topdressing in the ditch. Plant ash is not only a natural potash fertilizer, but also can protect the underground roots of Chinese chives from ground maggots.
Plant leeks evenly in the ditch at a spacing of 20 cm, leaving eight or nine for each pier, with a maximum of 10. Too dense will affect each other and compete for limited resources, and the leeks will be as thin as hair, which will affect the taste of food.
Step 3 cover the soil
After transplanting, it is advisable to cover the soil without burying tillering nodes. When covering soil, it should be noted that the Leek Valley after covering soil is 5-6 cm lower than the row spacing. This is for irrigation convenience and later soil cultivation. After stepping on the soil and watering it, the transplanting work is over.
Water leeks twice a week after transplanting. When leek seedlings grow to 15-20 cm, a small amount of urea or other fertilizers can be applied after watering to promote their rooting.
In order to support and strengthen the roots, it is best not to harvest them in those years, let them grow freely, and supply water and fertilizer in time and properly. In this way, you can eat fresh leeks in the next spring.
How long can the old leek roots be cut after transplanting?
After transplanting the old leek roots, cut them at least half a year later. After transplanting, it is necessary to accumulate nutrients as much as possible, which is very helpful for the growth of leeks and grows stronger.
The transplanting time should also be selected, and July and August are the most suitable. If you transplant it at this time, let it grow naturally in autumn and winter, and don't cut it. You can cut it in the next spring, and the longer you cut it, the longer it will be.
