Perilla planting method how to plant perilla

With the perilla entering the market, the cultivation of perilla has gradually become a large-scale cash crop from a weed that can be seen everywhere in the countryside. people pay more and more attention to the cultivation methods and planting techniques of perilla. Friends who don't know much about it might as well learn it together.

Perilla planting method

Perilla has strong adaptability, lax soil requirements, good drainage, sandy soil, loam, clay loam, front and back house, ditch edge, fertile soil cultivation, good growth. Vegetables are the best crop in the previous crop. Fruit trees can be planted under young forests. Spring sowing, the difference in sowing time between the north and the south is one month, March in the south and mid-late April in the north. Direct seeding in the border strip sowing, according to the row spacing of 60 cm ditch depth of 2-3 cm, evenly sow the seeds into the ditch, sow and cover the thin cheese. Hole sowing: row spacing 45 cm, plant spacing 25-30 cm, shallow cover soil. Watering immediately after sowing, keep moist, sowing rate 15-18.75 kg per hectare, direct seeding labor-saving, fast growth, early harvest, high yield.

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. For direct seeding and seedling raising, topdressing when the seedling is 30 cm high, loosen the soil and bury the fertilizer well. Apply fertilizer again before the ridge is closed for the second time, the method is the same as above. Perilla should be harvested in sunny days, with sufficient aroma and convenient drying. Perilla leaves should be harvested from late July to early August, when perilla is not in bloom. While collecting seeds, pay attention to the selection and retention of improved varieties. Select plants with strong growth and high yield, wait until the seeds are fully mature before harvesting, drying and threshing for seed use.

Harvest standard of perilla

In order to avoid the loss of yield caused by bird damage and scattered seeds, as soon as it matured at the top of the perilla plant, some fallen leaves of the whole plant were harvested immediately, bundled together and dried in the shade to promote ripening and yield increase. After it is fully dry, hit and thresh with a wooden stick on the cement floor or cloth, so that there is no soil and no miscellaneous wind, put it in a woven bag and store it in a dry place in the wind.

The stem turns yellow and the seeds can be harvested after a small amount of late fall when the plant is shaken. Early harvest is not good for grain ripening, low 1000-grain weight and low oil content. Too late harvest is very easy to thresh and cause yield loss, so we must grasp the harvest time. Cut from the root and tie it up at harvest. Spread out and dry and beat with a stick or sickle mallet. Perilla has fewer diseases and insect pests, and most of the diseases are rust, which are easy to occur in the seedling stage. there are orange spots on the back of the susceptible cotyledons, and the cotyledons are ruptured after enlargement, falling leaves seriously and affecting fruiting. Aphids are the most common insect pests, and if they occur, common aphid control agents can be used to control them.

The origin of perilla

Perilla is mainly located in Southeast Asia, Taiwan, Jiangsu, Anhui, Henan, Jiangxi, Hunan and other central and southern regions, the Himalayas, Japan, Myanmar, the Korean Peninsula, India, Nepal also introduced this kind, while North America also has growth. Perilla is suitable for planting in the frozen temperate zone, the soil requirements are not strict, the edge of the village, the land, good drainage, sandy soil, loam, clay soil, before and after the house, the edge of the gully, fertile soil cultivation, good growth.

Preservation method of Perilla frutescens

1. Keep in the refrigerator

Fresh perilla, washed, slightly dried, packed in a fresh bag, stored in a fruit and vegetable box in the refrigerator, can be kept fresh for a week or so.

2. Bottle preservation

Perilla can also be stored like flowers, trimming the end of the stem and putting it in a bottle filled with water. Cover it loosely with a plastic bag to keep it fresh for at least a week.

3. Sun-drying and preservation

After washing the perilla, remove the leaves and spread them in a cool and dry place. after drying, seal them with a fresh bag and store them in a dry environment.

4. Foam box preservation

Put the perilla leaves in a foam box, cover and preserve them to isolate them from the oxygen in the air, inhibit the aerobic respiration of perilla leaves, and help to keep them fresh.

Because perilla itself is a kind of weed, the viability of perilla is very strong, the requirement for soil is relatively low, and it is relatively difficult to plant. In addition to planting perilla requires certain technology, the harvest and preservation of perilla is also an important factor affecting the planting efficiency of perilla.
