Edible Gardening 0 views
Characteristics: The growth period (from emergence to maturity) is 120 days, and the tuber dormancy period is long, making it a late-maturing variety. The plant type is semi-erect, with a plant height of 60-70 cm. The seedlings have strong growth vigor, and the plants are luxuriant, with green stems, dark green leaves, and white corollas, and they do not set fruit naturally. Tuber formation is concentrated, with 3-5 tubers per plant. The tubers are large and uniform, with the rate of large and medium tubers above 95%. The tubers are oval, with light yellow skin, light yellow flesh, and relatively deep eyes. Storability is slightly poor. It is highly resistant to late blight. In regional trials, the yield was 1598.3 kg per mu, an increase of 39.2% compared with the control. Suitable range

Suitable range: Suitable for planting in arid areas and high-cold, humid, and semi-shaded areas.

Cultivation points: The usual planting density is 4500 plants per mu, and about 3000 plants per mu for early and poor soils. Sun the seed potatoes before sowing, cut and plant at the same time, and never pile them up for a long time after cutting. Plant relatively deep and hill up high, apply topdressing early, and manage for early promotion and rapid growth.
