A vigorous and early-maturing hybrid cucumber. The first female flower appears on the 3rd–4th node, with fruit setting mainly on the main vine. Fruits are uniform light green, around 23 cm in length, crisp and non-bitter with excellent eating quality. The variety shows strong resistance to major diseases and good tolerance to environmental stress. Suitable for spring–summer and summer–autumn cultivation. Average yields reach over 4,000 kg per mu( 666.7m² ) in spring–summer and over 2,000 kg per mu( 666.7m² ) in summer–autumn seasons.

Cultivation Practices

• Seedling age: approximately 30 days.
• Transplanting under plastic film with small tunnels.
• Planting density: 2,500–3,000 plants per mu.
• Apply abundant basal fertilizer, frequent topdressing, and timely pest and disease control.
• Frequent harvesting is recommended.
• Under low temperatures in early stages, hormonal flower treatment may be used to improve fruit set.

Recommended Planting Areas

• Suitable for Chongqing and the middle and lower reaches of the Yangtze River, and for early-spring protected cultivation in Jiangsu, Zhejiang, and Shanghai.
• In Chongqing, nursery raising is recommended in large (or medium) plastic tunnels or electrically heated seedbeds from January 21 to February 20.
• In other regions, trial planting is required before large-scale introduction under similar climatic and ecological conditions.

Fruits are long and cylindrical, straight with pointed tips. The fruit surface is a glossy dark purple without significant color variation between sun-exposed and shaded sides. The area beneath the calyx is deep purple. On average, fruits are about 36 cm in length and 6 cm in diameter, with an average weight of approximately 400 grams per fruit. The flesh is loosely textured with good quality.

Key Cultivation Practices:

• Early Spring Cultivation: Use 20–30 grams of seeds per mu (1 mu ≈ 666.7 m²), with a final planting density of 2,200–2,800 plants per mu.
• Timely Harvesting: Especially for the first and second fruits, early harvesting is recommended to promote the development of middle and upper fruits.
• Pest and Disease Management: Monitor and control key diseases and pests such as bacterial wilt, Fusarium wilt, Phytophthora blight, brown spot, and red spider mites.

Recommended Planting Regions and Seasons:

• Suitable for Chongqing and the middle and lower reaches of the Yangtze River, including Jiangsu, Zhejiang, and Shanghai.
• For early spring cultivation, sow seeds between October 11th and 20th.
• In other regions with similar climatic and ecological conditions, trial planting is recommended before large-scale cultivation.

Cultivation Guidelines

In the Yangtze River Basin (Spring Cultivation):
Sow seeds between October 11 and 20. Transplant seedlings grown in greenhouses around March 5 of the following year.

Autumn Cultivation:
Sow seeds between May 1 and June 10, and transplant between June 21 and July 10.

Northern Regions:
Adjust sowing and transplanting schedules based on local climate conditions and cultivation practices.

Recommended Growing Areas:
Particularly suitable for Chongqing and surrounding regions.

Trial Introduction:
In other areas with similar climatic and ecological conditions, planting is recommended only after successful trial introductions.

*Note: 1 mu ≈ 666.7 square meters or about 0.165 acres.

Recommended Planting Regions & Seasons

• Suitable for cultivation in Yunnan, Guizhou, Sichuan, Chongqing, the Yangtze River Basin, and Jiangsu-Zhejiang-Shanghai regions.
• In the Yangtze River Basin, sow in seedbeds from January 21 to February 20, transplant in greenhouses in late February or under plastic mulch in early to mid-March.
• For other regions with similar climate and ecological conditions, trial planting is advised before large-scale cultivation.

Key Cultivation Practices
Recommended planting density is 2,000 plants per mu (approx. 30,000 per hectare), with 66 × 50 cm spacing. Train vines onto trellises promptly. When 3–4 young fruits appear, perform successive pinching, remove lateral branches, and retain the main stem to promote fruit setting. During low temperatures, hormone treatment or manual pollination with male flowers can improve early fruit set.

Adaptability
This variety is highly adaptable and demonstrates high yield, stability, and strong resistance to stress under proper cultivation and management.

Cultivation Practices

1. Planting density: 3,000 plants per mu.
2. Bed width: 1 m, single row planting. Row spacing 50 cm, plant spacing 40 cm.
3. In rainy seasons, ensure timely drainage through ditching. Prevent pests and diseases. Harvest promptly for best quality.

Main Cultivation Practices

1. Transplant seedlings at about 30 days old using plastic mulch plus small tunnel covering.
2. Planting density: 2,000–2,500 plants per mu (≈30,000–37,500 plants/ha). Apply abundant base fertilizer and frequent topdressing; implement timely disease prevention. Harvest frequently. Under low temperatures in early stages, use hormone spraying to improve fruit set.

Suitable Regions and Sowing Season

1. Adapted to Chongqing and the middle and lower reaches of the Yangtze River, including Jiangsu, Zhejiang, and Shanghai.
2. In Chongqing and surrounding areas, sow in large/mid-sized plastic tunnels or electric-heated seedbeds from January 21 to early February.
3. In other regions with similar climatic and ecological conditions, trial planting is recommended before large-scale cultivation.
