Second, what are the key points for perilla planting?

1. Select the place

Perilla is very adaptable, but if we are growing commercially, we still need to choose a plot that is more suitable for perilla growth. The light should be sufficient, the drainage performance should be good, try not to choose clay. After selecting the land, turn the land 15 centimeters deep and flatten the bed.

2. Sowing seeds

Perilla is sown in spring, generally in March in the south, and a month and a half later in the north than in the south. When sowing, dig a ditch 3 cm deep in the border, 60 cm away, and then sow the seeds evenly and cover the soil. Hole sowing can also be carried out, the row spacing can be slightly smaller, the plant spacing is between 25 and 30 centimeters.

3. Transplanting

The way of transplanting is generally carried out under poor planting conditions. Add plant ash to the seedbed before sowing, water it thoroughly, and then sow the seeds. Keep the seedling bed moist during seed germination, wait until the seedlings grow to 3 to 4 centimeters, and water once the day before transplanting, so that the survival rate of seedlings will be higher. Transplanting should be done when the sun is not strong. In order to slow down the seedlings. After the transplanting is completed, we have to apply some organic fertilizer with a low concentration. If the weather is dry, you can water it every 2 to 3 days, and water less at other times.

1. Topdressing

The growth time of perilla is not long, usually only two and a half months. Therefore, fertilization is mainly based on nitrogen fertilizer to increase the nutrients of plant vegetative growth. Generally speaking, topdressing is carried out twice during the growth of perilla, and the first time is when the plant grows to 30 centimeters high, farm manure or chemical fertilizer can be used. Carry out the second topdressing before sealing the ridge and be careful not to touch the leaves.

2. Watering

Perilla should be watered in time if there is a lack of water at the beginning of planting, and as little as possible in the subsequent growth process. When you encounter more cases of Rain Water, you should pay attention to drainage to prevent fallen leaves.
