The method and time of transplanting leek

There are two methods of transplanting leek: pinch planting and single plant transplanting. After the row spacing is determined, the holes are opened according to the hole spacing in the ditch, the hole depth is 10~13cm, 30 plants are planted when the hole distance is 17~20cm, and 15 plants are planted when the hole spacing is 7~9cm. Single plant planting is to open the ditch of 10~13cm according to the predetermined row spacing, and put the leek plant evenly according to the 1~2cm plant spacing in the ditch. When transplanting, it is generally transplanting from late July to early August.

Points for attention in transplanting Chinese chives:

1. Soil preparation: leek is afraid of waterlogging, so try to choose high dry land with deep soil layer and good drainage and irrigation. The front lane must avoid onion and garlic vegetables, otherwise the performance of repeated cropping is serious. Deep ploughing of leek should be carried out before planting, and then the ridges should be built according to the local climatic characteristics. Generally, high border cultivation is adopted in the south, with a width of 1 to 1.5 meters and a height of 10~15cm. Flat border cultivation is adopted in the north, with a width of 1.3 to 1.5 meters, a length of about 10 meters, a ridge width of 20cm and a high 12~15cm. Those cultivated in small arched sheds are generally built into a wide bed of 2 to 2.5 meters.

2. Fertilization: leek is a fertilizer-loving vegetable and has higher requirements for nitrogen and phosphorus fertilizer, so some human manure can be applied before planting, generally using 10000 kilograms per mu of land.

3. Watering: three days before seedling planting, the leek should be lightly watered once in order to raise the seedling. At the same time, the length of leek should be controlled at about 8~10cm, which can reduce leaf water evaporation and slow down the seedling quickly.

4. Reasonable close planting: general row spacing 30~35cm, the number of seedlings planted per mu is about 80 000 ~ 100000, if it is a variety with upright plant type, such as Jinjiu No.1, 791, etc., the row spacing is generally in 25~30cm, and 100000 ~ 120000 seedlings per mu.

5. Planting forms: there are two main types of open field leek: furrow planting and border planting, in which the row spacing of furrow planting is generally 30~35cm, the cluster spacing is 4~7cm, each clump has 2 ~ 3 plants, and the soil sealing depth is 2 ~ 3 cm with leaf sheath exposed to the ground. The row spacing of furrow planting and flat bed cultivation is 25~30cm, the cluster spacing is 7~10cm, each clump has 2 to 3 plants.

The above is the detailed introduction of the transplanting method and time of leek and the matters needing attention in transplanting. I hope it will be helpful to everyone.
