How do you grow Pearl Zucchini? Here is a detailed introduction.
Pearl Zucchini is an ultra-early-maturing first-generation hybrid, and was an award-winning variety in the 1997 All-America Selections. Its fruit is round and spherical, with dark green, glossy skin and grayish-green speckles. It is a new zucchini variety with great development potential.
1 Characteristics and traits
This variety is an ultra-early-maturing first-generation hybrid. It can be harvested 36 days after sowing, reaching market 10 days earlier than the currently main domestic variety, "Early Green First Generation" zucchini. The plant has strong growth vigor, a dwarf bush habit with no vines, and an average plant height of 70-80 cm. The fruit is round and spherical, with dark green, glossy skin and grayish-green speckles. The flowers are yellow and trumpet-shaped. 5-7 days after flowering, young fruit of about 300 g can form. After entering the harvest period, more than 3000 kg per mu can be harvested cumulatively over 1 month of picking.
2 Key cultivation points
① Raising strong seedlings: Soak plump seeds in 55°C hot water for 35 minutes, then remove and drain off the water. Place them in a small porcelain bowl, cover with a moistened piece of cloth, and keep at 25-30°C to promote germination until the seeds split and show white. Then place them into 8 cm x 8 cm nursery pots prepared with nutrient soil, water thoroughly, and maintain the temperature at 25-30°C. A seedling age of 20 days is sufficient. When the seedlings grow more than 2 cotyledons, pay attention to ventilation and hardening off the seedlings.
② Transplanting management: Keep 2000-2200 plants per mu. Because Pearl Zucchini has a well-developed root system, base fertilizer should be applied deeply: 800 kg of decomposed farmyard manure per mu, 5000 kg of diammonium phosphate, and 2500 kg of biological potassium fertilizer. In greenhouse cultivation, because the pollination rate is low, use 15-20 mg/kg of 2,4-D to dip flowers daily from 6 to 7 o'clock. After dipping flowers, strengthen ventilation in the greenhouse and loosen the soil in time. Do not water before the fruit sets.
③ Pest and disease control: The main diseases are Phytophthora blight, powdery mildew, and viral disease, and prevention should be the priority. For chemical treatment, spray 25% metalaxyl wettable powder at 800 times, or 40% fosetyl-aluminum plus mancozeb at 200-300 times. The main insect pest is aphids, which can be controlled by spraying 10% Yibianjing at 300 times on the leaves.
