What nutritional value does the Boyang No. 9 melon have?

Every 100 grams of Boyang No. 9 melon flesh contains 90-93 grams of water, 9.8 grams of carbohydrates, 29-39 milligrams of vitamin C, and also contains small amounts of protein, fat, minerals and other vitamins, etc. The soluble solids content in the center is 12%-13.5%, and the soluble solids content at the edge is 10.5%. It is a hybrid, thin-skinned type, with suitable sweetness, a crisp texture, a delicate fragrance, relatively thick flesh, and a well-proportioned fruit shape.

I. Key Points of Boyang No. 9 Melon Cultivation Techniques

It is suitable for cultivation in Tianjin, Shandong, Hebei, Henan, and Jiangsu in overwintering greenhouses, early spring greenhouses, spring and autumn greenhouses, and open fields. The key cultivation points are as follows:

1. Grow strong seedlings, using nutrient pots or plug tray seedling production.

2. Apply sufficient base fertilizer and use nitrogen, phosphorus, and potassium fertilizers reasonably.

3. Cultivation methods: In protected cultivation, single-vine or double-vine pruning can be used. For single-vine pruning, 2000-2200 plants/mu; for double-vine pruning, 1400-1600 plants/mu. The fruit-setting node position depends on local cultivation habits. For open-field cultivation, the plant spacing is 40 cm × 110 cm. Pinch the growing tip at 4-5 leaves and keep 2-3 secondary vines. Grafting is recommended to increase disease resistance and raise yield.

4. Management during the fruit-setting period: After fruit set, promptly apply fruit-swelling fertilizer together with watering, strengthen water and fertilizer management, and control watering when entering the ripening stage to improve fruit quality. In the middle and late stages of fruit setting, promptly remove lower old leaves to facilitate ventilation and light penetration.

5. Pest and disease control: Focus on prevention. If pests or diseases occur, promptly use pesticides for treatment.

II. Precautions for Growing Boyang No. 9 Melon

1. Improper soil, climate, or cultivation management may cause losses.

2. Excessive use of nitrogen fertilizer can easily lead to overly vigorous plant growth, difficulty in fruit setting, and bitter flesh, etc.; swelling agents can easily lead to deformed fruit, poorer quality, and a prolonged development period, etc.; improper concentration of flower-dipping chemicals can easily lead to fruit cracking and bitter flesh, etc.

3. Pay special attention to the control of fungal diseases such as powdery mildew and downy mildew, and bacterial diseases such as bacterial fruit blotch.

4. Harvest at the proper time. When overripe, the flesh color will become orange-green and the flesh will soften. Avoid bringing unripe melons to market.
