Cultivation techniques of double-film early maturing pumpkin

Western squash is a hybrid of Indian and Chinese squash, known for its high levels of calories and vitamin C. It also contains twice as much vitamin E as Chinese squash. The flesh is sweet and powdery, making it ideal for storage and transportation. It can be stored in cold storage at 7–10°C for up to four months. In recent years, farmers have started using small greenhouses with plastic film to cultivate small pumpkins. This method allows the pumpkins to be harvested as early as late May or early June, extending the market supply by over two months. With a yield of 2000–3000 kg per mu, the income can reach 6000–8000 yuan per mu. Here are the cultivation techniques: First, choose early-maturing, cold-resistant varieties with flat, round fruits weighing 1.5–2 kg. These should have sweet, dense flesh and good market value. Varieties like Dongsheng, Changshou, Chestnut Crystal, and Chestnut are recommended. Second, prepare strong seedlings. From late February to early March, seeds are soaked in warm water (40–50°C) for two hours, then wrapped in a damp cloth and kept at 25–30°C for 36–48 hours until they sprout. Sow them in nutrient-rich soil, cover with 1.5 cm of fine soil, and place a plastic sheet on top. Maintain daytime temperatures between 25–30°C and nighttime temperatures between 15–18°C. After the first true leaves appear, remove the topsoil and fill gaps with dry soil to keep the temperature around 20–25°C during the day and 13–15°C at night. Every 5–7 days, apply a 0.1% potassium dihydrogen phosphate solution using a watering can. Seedlings should be ready for transplanting after 30–35 days, with 3–4 true leaves and no legginess. Third, apply base fertilizer once. In early March, mix 2000 kg of composted chicken manure, 1000–1500 kg of chicken manure, 50–100 kg of cake fertilizer, and 30–40 kg of 45% compound fertilizer with 10–15 kg of potassium sulfate. Spread this evenly and form raised beds 2.5 meters wide and 20 cm high. Spray 100–50 kg of Dole mixed with water to control weeds. Cover the beds with 80–100 cm of plastic film and build an arch greenhouse using bamboo or thin green bamboo. Cover with non-dripping film and close the shed to raise the temperature. Fourth, transplant seedlings in late March to early April on sunny days. Plant one plant per hill, with 45–50 cm spacing between plants and 50 cm between rows. For two rows, use 90 cm row spacing. You can also intercrop cabbage or leeks in the empty spaces. Fifth, manage the field carefully. After planting, maintain a temperature of 20–30°C during the day and 15–18°C at night. If there's a cold snap, cover the greenhouse with 1–2 layers of shade netting at night. During flowering and fruit set, ventilate on sunny days to maintain 25–27°C during the day and 16–18°C at night. Once the outside temperature stabilizes above 15°C in late May, remove the greenhouse. Sixth, manage vine growth by pruning single or double vines, spreading them out to avoid shading and encourage root development. Perform artificial pollination in the morning (7–9 AM) when female flowers open, by placing male flowers directly on them. Seventh, manage fertilization. Apply diluted manure 1–2 times after planting to promote seedling growth. After the first female flower opens, add 10 kg of urea per mu to 1000 kg of livestock manure. When the first fruit begins to grow, apply 15 kg of urea and 5 kg of potassium sulfate, 50 cm from the root, to promote fruit enlargement. After harvesting the first batch, apply 15–20 kg of urea and 100 kg of cooked cake fat to support the second and third batches. Keep the soil moist to prevent premature aging. Eighth, focus on disease prevention. Common pests include viral diseases, powdery mildew, and leaf spot. Control viruses by managing aphids and spraying a 400-fold solution of probiotics mixed with 20 grams of high-quality bacteria. Use triadimefon at 1500 times dilution for powdery mildew and chlorothalonil at 500 times for leaf spot. Ninth, harvest after 37–40 days when the fruit is fully developed, with yellow flesh and a weight of about 1.5 kg. Harvest on a sunny day, cutting the stem with a knife and leaving 4–5 cm of stem. Also, you can pick tender pumpkins 15 days after flowering for consumption.
