To grow high-quality tomatoes, it's essential to go beyond just applying basic fertilizers and include phosphorus and potassium supplements. Timely pruning, proper use of plant growth regulators, disease prevention, and controlling humidity are all crucial factors. Additionally, scientific management is necessary to prevent fruit drop and boost overall yield. One commonly used substance is the spotted flower hormone, particularly 2,4-D (dichlorophenoxyacetic acid). It's important to carefully control the dosage based on environmental conditions.
The concentration of 2,4-D depends on the temperature inside the greenhouse. When the temperature is above 15°C, a concentration of 10 mg/L is recommended—this means adding 1 to 14 drops of the original solution to 1 liter of water, then shaking well. If the temperature is below 15°C, increase the concentration to 15 mg/L, which requires 18 to 19 drops per liter of water. After mixing, it’s a good idea to add a small amount of red pigment as a visual marker to avoid confusion during application.
To further protect the plants from diseases like gray mold, especially during flowering or pollination, you can mix 50% Sikronin or Nylon into the 2,4-D solution. This helps in maintaining healthy crops and improving productivity. Always follow safety guidelines when handling these chemicals and ensure proper ventilation in the growing area. With careful attention and proper techniques, you can significantly enhance both the quality and quantity of your tomato harvest.
