1. Control the growth of tomatoes and prevent them from growing. After the occurrence of the length, 15% paclobutrazol 1500 times or 500 times foliar spray can be used to inhibit vegetative growth.
2. Avoid high temperature effects. When the temperature in the shed reaches 35 °C and lasts for more than 2 hours, it will cause the flower bud differentiation of the tomato to be blocked, especially the night temperature should not be too high, otherwise the stem will be long and the flower will fall easily.
3. Avoid excessive nutrient supply and insufficient nutrient supply due to partial application of fertilizer. Generally, the method is as follows: for example, the first ear is 3, the second ear is 3 to 4, the third ear is 4, and the upper ear is 4 to 5.
4. The ratio of the anthers should be reasonable. Pay attention to the temperature when you order the flower, and lower the concentration of the anther at the higher temperature.
