Non-pollution Production Technology of Three-membrane Watermelon
The selection of production bases is based on areas with a better ecological environment, free from pollution sources within 1500 meters. The soil has a medium texture, good drainage, and meets the standards for pollution-free watermelon cultivation. Farmland, soil, and irrigation water quality are all suitable for producing high-quality, safe watermelons.
Soil preparation involves deep plowing in winter, followed by the application of 5–6 tons of high-quality, harmless compost per 667 square meters. Before freezing, high-yield ditches are dug, and full-layer fertilization is applied. A one-time fertilization method is used to save time and labor while improving fruit quality. Organic manure such as pig or sheep manure (4–5 tons), decomposed chicken manure (1–2 tons), and cake fertilizer (soybean, peanut, or cotton) are mixed with water and applied. Diammonium phosphate and compound fertilizer are added, then the soil is thoroughly mixed and filled into the ditch. At the bottom, crop straw (wheat or corn) is layered with soil to enhance fertility and moisture retention. After filling, water is poured along the ditch, and the soil is cultivated to warm it up and prepare for planting.
Watering is done three times during the growth cycle: planting water, vine promotion, and fruit expansion. Watering should be done on sunny mornings, avoiding flood irrigation to prevent disease spread and conserve water. The frequency depends on the growth stage, soil moisture, and weather conditions.
For seedling cultivation, high-quality, disease-resistant varieties are selected. Seeds are treated with carbendazim or mancozeb before sowing in greenhouses. Seedlings are kept at optimal temperatures (20–30°C during the day, 10–25°C at night). Healthy seedlings have thick hypocotyls, short internodes, and dark green leaves.
Before planting watermelons, choose plots not used for melons in the past two years to reduce soil-borne diseases. Planting schedules vary depending on the crop type—three-membrane watermelons are planted in mid-December, transplanted in mid-February, and harvested in April. Two-membrane watermelons are planted in mid-February, transplanted in mid-March, and harvested in June. Spacing is 1.7m between rows and 0.5m between plants, totaling 900–1000 plants per 667 square meters.
Straw mulching and protective coverings are used to control pests and diseases. Three-membrane watermelons are covered with large arch sheds, small arches, and plastic films to manage humidity and temperature. Bermuda sorghum is planted alongside to provide shade and support. Insect traps, mechanical weeding, and proper ventilation help control pests.
Temperature and humidity management is crucial for disease prevention. After transplanting, initial sealing helps raise ground temperature. Once seedlings acclimate, gradual ventilation is introduced, keeping daytime temperatures around 28–30°C and nighttime temperatures above 15°C.
Vine management includes retaining one main vine and 1–2 side vines, while burying others to improve air circulation. High-quality plant ash is applied before flowering to disinfect and strengthen the plants. Artificial pollination or bee introduction enhances fruit set. Fruits are carefully selected, and paper bags are used to protect them from damage.
Chemical pesticides are used sparingly, following strict guidelines. Preventive measures are prioritized, and biological pesticides with low toxicity are preferred. Spraying is avoided 20–25 days before harvest, and insecticides are stopped 10 days prior.
Harvesting occurs 25–28 days after planting. Watermelons are picked with fresh leaves, washed, and stored in shaded areas for 2–3 days to reduce pesticide residues and improve marketability. After harvesting, the soil is cleared to prevent disease transfer and support the next crop.
The watermelon industry in Mengsi Town, Wenshang County, covers 850 hectares, producing 4000kg per 667 square meters for three-membrane watermelons and 3200kg for two-membrane ones. With an output value of 8000–12,000 yuan per acre, it significantly outperforms traditional farming methods. Products are popular, in high demand, and exported to numerous cities across China.
