1. Loosening the soil with large ridges: Cultivating loose soil in combination with the application of high-activity bio-organic fertilizer can significantly improve soil fertility and permeability. Root-breaking techniques help reduce plant growth potential, encourage root sagging, and minimize decayed roots. This practice also helps prevent long-term surface salt damage caused by excessive fertilizer use.
2. Planting roots and cultivating soil: Solanaceous vegetables are often affected by diseases such as root rot, blight, yellow wilt, and bacterial wilt. Applying Gaomei Shi organic humic acid liquid fertilizer or Kekesu fertilizer can effectively reduce root salt damage and suppress disease development. Additionally, this method supports stem growth and extends the fruiting period.
3. Removing old and diseased leaves: For crops like tomatoes, melons, and beans, removing old and diseased leaves is a highly effective strategy to reduce nutrient loss and control pests and diseases. It promotes healthier plant growth and improves overall yield.
4. Replenishing plant nutrients: Applying foliar sprays containing high concentrations of amino acids and humic acid fertilizers provides direct nutrient supply to the leaves. This enhances photosynthetic product accumulation, leading to higher yields and better crop quality.
5. Regular monitoring and control of epidemics: At this stage, plants grow rapidly and produce high yields. However, the high temperature and humidity environment creates favorable conditions for the quick spread of Phytophthora infestans. Therefore, it's essential to implement strict disease prevention measures to avoid serious losses.
6. Adding bio-organic fertilizer: Many farmers believe that potassium, calcium, and micronutrients are the most important for greenhouse vegetables. As a result, they often rely heavily on high-nitrogen and high-potassium compound fertilizers. However, after years of continuous cultivation, many greenhouses have accumulated significant amounts of inorganic salts. Only bio-fertilizers—such as phosphate-solubilizing bacteria, potassium-solubilizing bacteria, and actinomycetes—can break down these salts, improve fertilizer efficiency, and enhance fruit quality. As the saying goes, "farming without manure is like smashing." Bio-fertilizers improve soil structure, while organic fertilizers enrich the soil. By applying different formulas at various growth stages, farmers can achieve high yields, high quality, and high efficiency. During this time, due to high ground temperatures and humidity, harmful salts in the soil rise, causing an alkali return phenomenon. To counter this, it's recommended to apply bio-organic or chelating fertilizers.
7. Ventilation and moisture retention: Implement proper ventilation strategies based on weather conditions, crop type, and growth stage. For example, close vents early, open them late, and ventilate for half an hour during the night. This helps promote nutrient accumulation. During this short period, the air has high carbon dioxide levels and the outside temperature is low, making it ideal for cooling and reducing heat stress.
