Detailed Explanation of Tomato Color-Break Stage Management Techniques
Tomato is a vegetable that many people enjoy eating very much. It can be stir-fried or served cold, and it is a vegetable with very high nutritional value, welcomed by many people. Because the tomato planting area is still relatively large now, and when growing tomatoes, management work is very important. This is especially true during the color-break stage. So how should tomatoes be managed during the color-break stage? Let's take a look together with the editor below!
1. Scientific Fertilization
The tomato color-break stage is a very important growth period. This period directly affects the yield and quality of tomatoes. Therefore, we must first do a good job of fertilization. When fertilizing, organic fertilizer should be the main type, combined with various nutrient elements. Most importantly, an appropriate amount of potassium fertilizer should be applied as a top dressing. An appropriate amount of potassium fertilizer is very beneficial for the expansion and coloring of tomato fruit. It should be noted that potassium fertilizer should be applied before the color-break stage, because the plant cannot absorb potassium fertilizer immediately; it takes a certain amount of time to be fully absorbed and utilized. If it is applied during the color-break stage, then it will basically have no effect.
2. Temperature Regulation
During the tomato color-break stage, temperature regulation is relatively important. Appropriately increasing the temperature helps tomatoes color up. However, the degree of temperature increase must be paid attention to. Tomato fruit generally ripens from the bottom upward, so if the temperature is changed for only one or two trusses of fruit, then it is very unfavorable for the overall growth. Moreover, if the temperature remains too high for a long time, then tomatoes are prone to excessive vegetative growth, flower and fruit drop, and various other phenomena. Therefore, during the tomato color-break stage, keeping the daytime temperature at around 28 degrees and the nighttime temperature at around 15 degrees is sufficient.
3. Reasonable Leaf Thinning
After tomatoes enter the middle and late stages of growth, leaf thinning work should be done well. Reasonable leaf thinning can improve the plant's ventilation and light penetration and promote fruit coloring. However, the degree of leaf thinning must be controlled well, and excessive leaf thinning must not be done. During the tomato color-break stage, the main targets for leaf thinning are useless leaves such as old leaves and yellow leaves on the lower part of the plant and diseased leaves on the whole plant. There are also some leaves that block sunlight. The leaves below the reddening fruit must not be removed. Otherwise, it will affect the plant's photosynthesis, leading to reduced nutrient accumulation, which will not only affect fruit coloring but also hinder fruit expansion.
4. Pest and Disease Control
Finally, of course, pest and disease control work should be done well. Humidity inside the greenhouse will rise somewhat, so the incidence of diseases will also increase accordingly. Therefore, during the color-break stage, we should focus on doing a good job of pest and disease control, such as gray mold and early blight. First, ventilate reasonably to remove moisture, and then spray appropriate chemicals for prevention. After a disease occurs, pay attention to promptly checking exactly what disease it is. Then take corresponding measures and choose the corresponding chemicals for control. When spraying chemicals, they can be used together with some foliar fertilizers such as chitosan and amino acids, which can effectively enhance leaf resistance.
