What are the methods for storing perilla seeds and raising seedlings?

Perilla has a rather distinctive aroma and a mild pungent taste, with a unique flavor that some people really enjoy eating. The price of perilla on the market is not cheap, and demand for perilla is fairly high, so more and more farmers are growing perilla. So how should perilla seeds be stored? What are the seedling-raising methods? Let's take a look together below.

1. How should perilla seeds be stored?

Perilla seeds have a dormancy period of up to 120 days. To break the dormancy of freshly harvested seeds, the seeds must be placed in a 3 degrees Celsius environment for 5 days, and soaked in gibberellin to promote germination. Seed germination is light-dependent. Harvested seeds should not be stored dry. After air-drying them in a cool place for 2-3 days, mix the seeds with an equal amount of river sand, maintain suitable moisture, put them into a basket and bury it in the soil to promote germination.

2. What are the seedling-raising methods for perilla?

1. Planting time

The growth period of perilla is generally about 120 to 160 days. Perilla is usually planted in spring. In northern regions, sowing is generally done in April, while in southern regions sowing is mostly done in March. If a protected cultivation model is used, the planting time is relatively more flexible, and growers can plan the sowing time according to local climate conditions and the intended time to market.

2. Sowing and seedling raising

Perilla seeds have a relatively high germination rate, so germination-promoting work is generally not carried out. Growers with the means can dry the seeds in the sun for two days before sowing to achieve a disinfecting effect. In addition, carbendazim wettable powder can be used to dress the seeds. Perilla can be sown by direct seeding, or raised as seedlings first and then transplanted. For regions with lower temperatures and drier weather, the seedling-then-transplant method can be used, as this can improve the survival rate of the seeds. Growers who raise seedlings and transplant should thin the seedlings once after the perilla seedlings sprout, doing so when the young seedlings have grown 2 true leaves. When the seedlings have grown to about 5 cm, they can be transplanted and established.

For growers using direct seeding, the planting plot needs to be prepared and fertilized before direct seeding. The base fertilizer should be mainly organic fertilizer, used together with chemical fertilizer, with the amount applied according to soil fertility. Use 3000 to 4000 kg of decomposed organic fertilizer per mu, and about 30 kg of urea. After direct-seeded perilla emerges, thinning is needed twice, in the first week and the second week after emergence respectively. The first thinning should keep a plant spacing of 5 to 7 cm, and the second should keep 10 to 14 cm, ensuring the plants have enough growing space later on.

3. Field management

From two months to 3 months after sowing perilla, its growth speed increases. At this time, it is necessary to ensure sufficient water and fertilizer for perilla. Growers need to topdress according to the situation, mainly with nitrogen fertilizer, which can be done together with watering, and can also be combined with foliar fertilizer spraying. As for pruning, if it is leaf-type perilla, the differentiated flower buds at the top need to be removed in time to reduce nutrient loss and extend the leaf harvest time.

The above is an introduction to perilla. Perilla has a variety of uses. Besides being edible, perilla also has medicinal value, and perilla seeds can also be used as oil material. Growers can choose suitable perilla varieties according to their planting needs.
