Soilless cultivation of muskmelon has gained significant traction in China in recent years. This method offers high-quality produce, premium pricing, and the advantage of not being limited by land availability or the challenges of continuous cropping. As a result, it has seen rapid development in more economically advanced regions. Currently, successful implementations have been reported in provinces such as Guangdong, Guangxi, Hainan, Shanghai, Fujian, Zhejiang, and Jiangsu, where it has generated considerable economic returns.
The key techniques involved in soilless muskmelon cultivation include careful selection of planting seasons and varieties, appropriate growing methods, seedling management, transplantation practices, pruning, and disease control. For instance, due to the plant's sensitivity to cold, fully enclosed automated greenhouses allow for year-round production. However, in areas without adequate heating or insulation, choosing the right season with minimal rainfall, ample sunlight, and a significant temperature difference is crucial. In regions like the Jianghuai Plain, Shanghai, and Zhejiang, planting should occur before the rainy season, while in Guangdong, autumn is preferred due to drier conditions, and in Hainan, the dry season is ideal.
Selecting disease-resistant, high-quality, and visually appealing melon varieties is essential due to the high investment and cost associated with soilless farming. The two primary cultivation methods are hydroponics and matrix culture. Hydroponics involves allowing roots to float in nutrient solutions, while matrix culture uses solid substrates like peat, perlite, or coconut coir, with nutrients added through irrigation.
Deep-water culture, widely used in southern China, is particularly effective for muskmelon. This technique ensures stable nutrient levels, better oxygenation, and optimal root growth. The system includes planting tanks, floating boards, reservoirs, and a circulation mechanism. Nutrient solution management requires regular monitoring, with adjustments made based on temperature and plant growth stages.
Matrix culture, although simpler and less costly, requires careful attention to nutrient balance and substrate quality. Organic substrates, such as those used in ecological soilless systems, reduce the need for frequent nutrient additions but require more precise management.
Seedlings are typically started in nutrient cups or trays, with transplanting occurring once they develop two true leaves. Proper spacing is important to ensure good light and air circulation, which helps prevent disease and improves yield.
Pruning techniques, such as single-vine training and fruit thinning, help optimize fruit size and quality. Protective measures, including the use of net bags for supporting fruits, are also common.
Disease prevention is critical in soilless systems. Common issues include bacterial blight, powdery mildew, and root rot. Preventive measures include maintaining dry stems, proper pruning, and using fungicides and bactericides when necessary. Timely application of treatments like thiophanate-methyl or colloidal sulfur can significantly reduce the risk of crop loss.
Overall, soilless muskmelon cultivation represents a promising approach that combines technological innovation with traditional agricultural practices, offering both environmental and economic benefits. With continued research and refinement, this method is likely to become even more widespread in the future.
