After vegetables are transplanted, many seedlings show signs of vigorous growth, characterized by thin and weak stems, excessive internode elongation, low root mass, weak roots, and shallow root systems. Therefore, to control the excessive growth of vegetables, adjustments should be made from the seedling stage. Specifically, control can be achieved through the following aspects:
Control Techniques for Vegetables in Hot Weather
-
Temperature Regulation in Greenhouses: During hot seasons, excessively high night temperatures can cause plants to grow vigorously. An effective method to reduce night temperatures is to decrease the heat storage of walls and soil during the day. This can be achieved through shading, watering, and planting climbing vegetables to provide shade.
-
Modest Fertilization: Farmers can delay the original watering time by 2 days and pay attention to the amount of water applied, ensuring thorough watering to avoid excessive irrigation. In summer, when evaporation is high, it's recommended to water moderately and cultivate properly to avoid excessive water control, which can affect normal plant growth.
-
Timely Fruit Retention and Proper Pruning: Based on plant growth, for vigorously growing plants, fruits should be retained earlier, and fruit harvesting should be postponed appropriately to compete for plant nutrients and reduce nutrient flow to the plant. Conversely, weak plants should be harvested earlier. Pruning of vigorously growing plants should be done later.
-
Selection of Appropriate Growth Control Agents: Choosing suitable growth control agents such as Flower King No.3 can induce plant cell transmembrane signal conversion, forcing vigorous nutrients to flow back, weakening the dominance of shoot growth rapidly. The main nutrient flow shifts towards fruit development, enhancing fruit expansion vitality, avoiding leaf enlargement, and improving field permeability.
In summary, when vegetables exhibit excessive growth, management should be focused on the above aspects. Do you have any other questions about growth control?
