How to grow pumpkins in Taizao Huali? (with key techniques of greenhouse cultivation and open field cultivation in early spring)

Taizaohuali is a variety of pumpkin, very early maturity, is a high-yield tender pumpkin. The plant grows steadily, and it is not easy to run vines and overgrow to affect fruit setting. Generally, it can set 3-5 fruits continuously. Under the condition of large fertilizer and water, each plant can harvest 12-15 melons, and the weight of single melon is 500-700 grams. In recent years, many growers have begun to plant this variety, so how do you plant Taihua Li pumpkin? What are the technical points of greenhouse cultivation and early spring open field cultivation?

1. Key points of extremely early maturity cultivation of Taihuali pumpkin in greenhouse

1. This variety can withstand short-term low temperature of about zero degree, and low temperature and short sunshine can promote the differentiation of female flowers, so this variety can be used for extremely early cultivation of tender pumpkin, early selling price, and improving economic returns.

2. Sowing in late December, keeping the soil dry in the greenhouse is conducive to improving the low temperature, watering the nutrient bowl with hot water, germination method is the same as open field cultivation, sowing 1-2 seeds/bowl. Heat line laying, seedling management and other open field cultivation seedling management.

3. The seedling age is about 60 days. After seedling training, select strong seedlings with dark green leaves and thick rhizomes, and transplant them to the greenhouse in sunny days. There are 3 compartments in the greenhouse, the width of the compartment is about 1.5 meters, each compartment is planted with 2 rows, the plant spacing is about 40 cm, and the area with low temperature can be added with small arch shed and double-layer insulation. After transplanting, the shed is sealed for about 7 days, and the seedlings are kept warm and slow, and the wind is the same after the seedlings are slow. The vine is about 1 meter long and tied to the upper frame, removing the small arch shed.

4. Remove the lower lateral branches and old leaves, pollinate with male flowers, or spray fruit spirit. Under normal weather conditions, it will be listed in early April.

5. Pay attention to the prevention and treatment of pests and diseases.

2. Key points of cultivation techniques of early flowering pumpkin in early spring

1. Choose paddy and upland rotation, soil planting with convenient irrigation, high ridge cultivation, herringbone cultivation, ridge width 1.6 meters, ridge depth 0.3 meters, ridge width 0.4 meters. After successful seedling raising, two longitudinal furrows are opened at 0.3m away from the furrow on the ridge surface, base fertilizer is applied in the longitudinal furrows, then plastic film is covered, holes are drilled on the plastic film according to the row spacing of 0.9m and the plant spacing of 0.4m, melon seedlings are transplanted in the holes, and 1800-2000 plants are planted per mu. Climbing cultivation ridge surface width of about 1.5 meters, ridge width of 0.3 meters. 0.3 m deep, 1 m plant spacing perforated transplanting, planting a row per row, planting about 550 plants per mu. Furrows were opened 0.3 meters away from the furrows and basal fertilizer was applied. Basal fertilizer per mu about 4000 kg farm manure and 50 kg compound fertilizer.

2. Seedling in the middle and late February, seedling in a nutrient bowl in a greenhouse, soaking seeds in warm water at 55 ° C for 4 hours, then wrapping them with wet gauze and placing them at about 30 ° C for germination, sowing the seeds in a nutrient bowl after white exposure, covering about 1 cm of nutrient soil, sowing 1-2 seeds per bowl. Cover plastic film, can also build small arch shed insulation. Remove the mulch after emergence. After the temperature rises again, remove the small arch shed.

3. After the vine falls, the vine is about 0,5-1 meters long, and the bamboo pole about 1.8 meters long is used to set up the herringbone frame and tie the vine to the frame. All the lateral branches below 5-6 nodes of melon vine are removed, and the upper lateral branches are left according to the situation. The main vine and the vine can bear melon at the same time. The lateral branches above 5 nodes cultivated by climbing can grow freely, and 3-4 roots can be left to bear melon.

4. 7 days before planting, the seedlings were cultivated in shed water control, and planted in late March and early April, and planted in sunny days. Before flowering, apply 0.5% potassium dihydrogen phosphate foliar fertilizer 1-2 times according to the situation. After fruiting, harvest 1-2 times according to the situation, and then apply 10-15 kg compound fertilizer per mu.

5. In rainy season in spring, pay attention to drainage. Summer and autumn temperature is high, easy to drought, can divert water into the ditch, fast irrigation fast discharge, also known as irrigation running horse water. Pay attention to pest control.
