First, choose disease-resistant varieties such as improved Jinchun 2 and Bomei 8. These cultivars have been specifically bred to resist common pests and diseases, making them ideal for sustainable and healthy crop production.
Second, nursery planting is crucial. After preparing the seedbed, plant seedlings in a timely manner. The best time to plant is around March 20th, within a 5-7 day window, depending on local weather conditions. It's recommended to plant in the early morning when the sun is gentle to reduce transplant shock. Avoid overloading the seedlings during planting, and ensure proper spacing for optimal growth. During the acclimatization period, maintain a stable greenhouse temperature but avoid excessive heat buildup. At midday, when temperatures rise, briefly ventilate the greenhouse to prevent overheating and improve air circulation.
Third, prepare the greenhouse before planting. (a) Soil treatment: Before planting, deeply till the soil to a depth of 30-40 cm, exposing it to sunlight to kill pathogens and weeds. Remove any leftover roots, leaves, or weeds from the previous crop. For greenhouses that have been used multiple times, it’s important to treat the soil to prevent future issues. Use organic manure, biological bacterial fertilizer, or silicon-calcium fertilizer to enrich the soil and promote healthy root development. (b) Greenhouse warming: 15-20 days before planting, cover the greenhouse with plastic film to raise the temperature. Additionally, disinfect the structure using insecticidal and fungicidal sprays to eliminate any lingering pests or diseases. (c) Land preparation and base fertilization: After plowing the field, apply 5,000 to 7,500 kilograms of well-decomposed organic fertilizer per 667 square meters to provide essential nutrients for the growing season.
Fourth, manage the vine growth period effectively. Spray bactericides such as Amisida, Cisco, OK Music, chlorothalonil, azithromycin, or aquamycin every 5-7 days to prevent fungal infections. Also, apply miticides like Mite Immediately or avermectin to control mites. To support cucumber growth, spray growth promoters before the peak production period. Fertilize every 10-15 days using high-potassium and calcium fertilizers, or specialized cucumber fertilizers to ensure balanced nutrition and strong plant development. Regular monitoring and timely intervention are key to achieving a successful harvest.
