In order to ensure the production of high-quality, disease-resistant, and high-yield crops, it is essential to select grafted seedlings from varieties such as No. 1 Xintaimici or other similar types. The rootstocks used for grafting should be carefully chosen, such as white or black pumpkin seeds, depending on market demands. Before sowing, it's important to disinfect both the seeds and the seedbed to promote the growth of healthy, disease-free seedlings.
Before planting, apply a generous amount of organic fertilizer combined with biological fertilizers. For example, use 7-10 cubic meters of well-rotted chicken manure, cow dung, or compost, along with 2-3 kg of biological nitrogen fertilizer. Additionally, add 4-5 kg of potassium fertilizer (mixed with fine soil at a ratio of 10-20 times) to enhance soil fertility and support plant development.
It is also crucial to clean the greenhouse thoroughly before fumigation. Remove all residual plants, leaves, and weeds from the previous crop. Before planting, use bactericidal agents like chlorothalonil or dichlorvos to treat the greenhouse, reducing the risk of pests and diseases by lowering their population.
For planting, create high ridges with a bottom width of 90 cm, an upper width of 70 cm, and a height of 12 cm, arranged in a north-south direction. The distance between the two ridges at the base should be 30 cm, and the top spacing should be 50 cm. Plant two rows of seedlings on each ridge, with a row spacing of 50-27-30 cm, and leave a watering ditch in the center. After planting, cover the ridges with mulch (width 0.9-1 m), make holes for the seedlings, and water through the film. This method helps increase ground temperature, ensures proper moisture, and reduces humidity, thus preventing diseases.
Scientific topdressing and reasonable watering are key to promoting plant growth. Fertilizing not only supplies necessary nutrients but also helps raise soil temperature, encouraging strong plant development.
When planting, you can use Harvest No. 1 to irrigate the roots, which promotes root establishment and enhances seedling resilience. After the fruit sets, apply Jianzhibao bio-fertilizer or Hezhen brand bio-organic fertilizer, applying water twice. From the flowering stage onward, spray Harvest No. 1 diluted 800 times every 5-7 days to improve plant resistance, increase yield, and enhance fruit quality.
Watering should be done carefully. Avoid watering before the fruit sets to encourage root development. Once the plant grows to about 10 cm, start watering, initially once every 10-15 days, then every 6-8 days later. Watering should be done on sunny days, and after watering, raise the greenhouse temperature to 32-35°C before ventilating and dehumidifying to prevent disease outbreaks.
Comprehensive pest and disease control is essential. In addition to measures like cultivating disease-free seedlings, adjusting plant density, reducing humidity, and controlling nutrition, it's important to use effective, low-toxicity pesticides such as polyoxomycin, Wuyincin, streptomycin, and avermectin. During rainy or foggy days, use high-efficiency, low-molecular chemical aerosols for timely fumigation to prevent disease spread.
