Black Pi Dong is the largest melon cultivar cultivated in South China, with an annual planting area of ​​more than 800,000 mu. At present, the main cultivars of black melon goose are still farmers, because the market demands for product quality are increasing day by day, and the pests and diseases in the food areas are serious. Therefore, it is difficult for farmers to meet the production needs, and urgently need the replacement of disease-resistant and high-quality varieties.
The Institute of Vegetables of Guangdong Academy of Agricultural Sciences selected and produced the first black hybrid melon “Black You Da†in our province. The variety has high yield (6,778 kg per mu, which is 13.87% higher than that of local farmers), and it is resistant to wilt disease and disease. The melon shape is beautiful (fruit cannonball shape, melon length 58-75cm, horizontal diameter 25cm, green skin, shallow ditches, smooth skin, meat thickness 5.5-6.5cm), neat, good quality (dense meat, soluble solids content High, adaptability, and other advantages, suitable for the market and production of Guangdong black-skin gourd demand.

2. 1.8 meters spacing, 0.8-1 meter away from spring plants, 50-70 centimeters from autumn plants, and about 500 acres per plant.
3, the entire growth period requires sufficient fertilizer and water. Basal fertilizer is mainly farmyard manure such as chicken cow dung. It requires 1000 kg of farmyard manure in Mushi.

Reduce water consumption 10-15 days before harvest to improve storage and transportation performance of wax gourd.

Epidemic diseases: rotation for crop rotation; bed soil disinfection, 25% metalaxyl powder 8g/m2; additional base fertilizer, appropriate control of water, after the melon grass mating or racking melon or padding, the rainy season appropriate early harvest. Chemicals control: Ank 1500 times, 77% can kill powder 400 times, Jin Lei Duo Mi 1500 times, spraying and irrigating roots at the same time for better results.
Zinc deficiency symptoms: Antai WP spray 600 times.
Hummer: 1500 times more efficient and powerful, 100 times the sea is out of insects, 600-800 times better in winter, vegetables like 1000 times, killing 1000 times.
Whitefly: 10% bufalin EC 1000 times, special effects for whitefly; 25% methyl ciprofloxacin 1000 times, effective for adults, eggs, and nymphs.
