When to plant perilla cultivation techniques

Direct seeding: generally sowing before and after the Qingming Festival, using strip sowing (the row spacing is 40 cm into a shallow trench with a width of 10 cm and a depth of 3 cm, and the seeds are evenly sown into the ditch) or hole sowing (digging holes according to the row spacing of 25-30 cm, plant spacing of 25 cm). Seedling transplanting: in the whole seedling border, the seeds are scattered evenly into the ditch, and 2-3 strong seedlings are planted in each hole after planting, and the finished products are zigzag, covered with soil and watered. Daily management: loosening soil and removing seedlings, timely topdressing, reasonable irrigation and drainage.

When it comes to perilla, I believe we all know that we often eat fish or some meat like to put perilla to pick up fresh, but also many people like to eat fried perilla, the consumption rate is very high. So do you know how to plant perilla? Let's get to know it with the editor.

When will perilla be planted

Perilla is propagated by seeds, divided into direct seeding and seedling transplanting. Generally speaking, perilla is carried out in spring, in the south in mid-March and in the north in April, because the weather is not very warm at this time, so it should be covered with film after sowing.

Cultivation techniques of perilla

1. Direct seeding: generally sowing before and after the Qingming Festival, using strip sowing or hole sowing. Strip sowing: on the ready border, open a shallow trench with a width of 10 cm and a depth of 3 cm according to the row spacing. Sow the seeds evenly into the ditch, cover the soil 1-1.5 cm, and slightly suppress, so that the seeds are closely combined with the soil, using about 0.5 kg of seeds per mu. Hole sowing: dig holes according to row spacing 25-30 cm, plant spacing 25 cm, cover a layer of thin soil after sowing, with seeds of about 300 grams per mu.

2. Seedling transplanting: on the whole seedling border, open a shallow ditch horizontally according to the row spacing of 15-20 cm, mix the seeds with fire soil ash before sowing, and spread them evenly into the ditch, using about 1 kg of seeds per mu, and cover with a layer of thin soil after sowing. Cover the border with a layer of plastic film or rice straw after covering the soil, and remove the mulch after the seedlings are unearthed. When the seedling height is 5 cm, keep the plant spacing 3-5 cm. When the seedling height is 10-15 cm, it can be planted out of the nursery when it has 4 pairs of true leaves. Planting should be carried out in a cloudy or sunny afternoon, and the seedling bed should be watered one day before the seedling, so that the roots can take soil and not hurt the roots. To plant along with planting, dig holes according to the row spacing of 25 cm × 30 cm on the finished border bed, and the diameter and depth of the hole are about 10 cm each. In the hole, an appropriate amount of fire-soil ash is applied and mixed evenly with the subsoil, and then 2-3 strong seedlings are planted in each hole, and the finished products are shaped, covered with soil and watered. About 10,000 seedlings are needed per mu.

Field management

1. Loosen the soil and remove seedlings. Weeding should be done frequently before plant growth and ridge sealing, and attention should be paid to inter-seedling and weeding in direct seeding area. when the height of strip sowing seedlings is 15 cm, the seedlings should be fixed by 30 cm, and the excess seedlings should be used for transplanting. The plants in the direct seeding field grow fast, and if the density is high, the plants grow too long, and few of them are unbranched or branched. The seedling field was loosened and weeded twice from planting to ridge closure.

2. Topdressing. Perilla frutescens for a long time is relatively short, the whole grass can be harvested two and a half months after planting, and the whole grass is used as medicine, so it is mainly nitrogen fertilizer. Concentrate fertilizer before closing ridges.

Topdressing when the seedling is 30 cm high, 1000 kg of human feces and urine or 8 kg of ammonium sulfate per mu, 10 kg of superphosphate, loosening the soil and cultivating the soil to bury the fertilizer. Apply fertilizer again before the ridge is closed for the second time, the method is the same as above. But be careful not to touch the leaves this time.

3. Irrigation and drainage. After sowing or transplanting, it will not rain for several days, so it should be watered in time. Pay attention to drainage in the rainy season, dredge the operation road, and prevent stagnant water from disorderly roots and defoliation.

The main value of perilla

1. Perilla leaf has the effects of clearing heat and detoxification, inhibiting fungal growth, raising blood sugar, blood coagulation, promoting intestinal peristalsis, sedation and sleeping. It can treat systemic rubella, pruritus, verruca vulgaris, uterine bleeding, uterine ptosis and other diseases. It can also be used for the treatment of bronchitis, chronic bronchitis and other diseases.

2. Perilla leaves play a role in regulating qi, and can also relieve depression and stop vomiting. For those with wind-cold symptoms, spleen and stomach qi stagnation, chest tightness and vomiting, perilla can be used to relieve symptoms. For those who are cold, perilla leaves can be used with patchouli every time; those who are too hot can be used with Coptis chinensis; those with partial qi stagnation and phlegm knot are often used with Pinellia ternata and Magnolia officinalis, and the effect is obvious.

3. Perilla leaves can also be detoxified and can be used to relieve abdominal pain, vomiting and diarrhea caused by eating fish and crabs. it can be used alone or with ginger and Angelica dahurica.

4. Perilla leaves are pungent in taste, warm in nature and rational in qi. Perilla leaves are often used to treat cold, cold, fever, cough, asthma and other diseases. Perilla can disperse the surface cold, strong perspiration, with ginger together, the effect is better. It is also taken with Wu almond, Qianhu, etc., if you have both qi stagnation and chest tightness, you can take it with Wu Xiangfu, tangerine peel and so on, such as Xiangsu Powder.

5. Perilla leaves can be used for pregnancy vomiting, fetal movement, chest and abdomen tightness. Often compatible with tangerine peel and Amomum villosum, it can achieve the effect of stopping vomiting and calming the fetus. If pregnant women use perilla to stop vomiting and calm the fetus, they need to be guided by a doctor.

The above is the perilla planting method summarized by the editor. I hope it can be helpful to everyone! In fact, if the consumption rate of perilla is relatively high at home, you can choose to plant some perilla in March or so. The survival rate of perilla is very high. It is very good to plant, so you don't have to worry about it.
