Controlling cherry tomato growth with growth regulators is a commonly used means of control, but improper application can cause problems such as small fruit and low commodity quality. The master Zhu of Xiqing Village, Tianliu Town, Shouguang City, Shandong Province, adopted the method of pressing vines to effectively control the plant growth.
Pressure vines can weaken the apical dominance, inhibit vegetative growth and regulate plant growth. In his greenhouse, it can be seen that the lower part of the tomato plant is clearly bent. Master Zhu introduced that the lower vines are mainly used to prevent the seedlings from growing in length and rushing to grow early, usually when the plants are 40 centimeters long. The press vines can directly overwhelm the stems of the plants from the bottom of 20 to 30 cm and fix them with soil. Under the premise of inhibiting the apical dominance of the plant, the characteristics of the tomato susceptible to adventitious roots are also fully utilized. The increase of the root coefficient and increase of the absorption of nutrient elements are conducive to the formation of strong seedlings.
The crushed vines in the middle are mainly used to regulate the balance between vegetative growth and reproductive growth, and are performed at the point of 3 to 4 spikes. This vine can bend or overwhelm the upper 20 cm of stems. In addition to dwarfing plants and regulating growth, the plants can be adjusted at the same height for easy management.
