During the color change of the tomato fruit, remove the yellow leaves, old leaves, and diseased leaves in time to avoid unnecessary nutrient consumption and increase the light to promote the color change of the fruit. However, in the summer with high temperature and strong light, the leaves around the fruit should be picked less and replanted. This is because most of these leaves are functional leaves, which are responsible for the important mission of photosynthesis, which is the key to determining tomato quality and yield, and it can also prevent The fruits are sunburned, so it is not advisable to remove them all hastily. In particular, it should not be removed excessively, but should be removed in an appropriate amount, focusing on nutrition to delay leaf senescence and improve leaf function.
Regarding how to pick and raise, it is recommended that vegetable farmers pay attention to the following points:
The leaves around the fruit are guaranteed to be "multiple but not crowded." Sunburn is caused by direct sunlight on the fruit. To prevent sunburn, you must ensure that there are leaves around the fruit, especially the upper leaves.
Most of the nutrients required for root growth are supplied by the middle and lower leaves. After all the leaves at the lower part of the fruit are removed, the leaves of the plant are greatly reduced, which reduces the formation of photosynthetic products, which is likely to cause insufficient nutrient supply for the plant. Second, the lower leaves are missing. The occlusion and direct sunlight around noon will cause the ground temperature around the root system to rise, which is not conducive to the growth of the root system. Therefore, do not remove all the leaves of the lower part of the tomato fruit, just reserve one or two functional leaves appropriately, and do not squeeze them to ensure photosynthesis of the plant, promote fruit expansion and color change.
Yellow leaves are heavily maintained. Plants in the middle and late stages of growth or weak growth should pay special attention to the maintenance of leaves, especially the maintenance of yellow leaves. It is recommended that vegetable farmers regularly spray amino acids, chitin, alginic acid or total nutrient foliar fertilizer to maintain the leaves , Improve plant resistance and disease resistance.
If leaf yellowing is severe, cytokinin or spraying of biostimulant products should also be used to delay leaf senescence and promote leaf return to normal.
