Do tomatoes need toppings? Because tomatoes grow and bear fruit at the same time, if they are not topped, they can really make tomato plants grow taller, but they will transport nutrients to the top to supply the growth of terminal buds, thus weakening the nutrient accumulation of fruits. For topping tomato, it is only for infinite growth type, not for limited growth type. In the process of tomato cultivation, it is also necessary to remove the lateral buds to prevent the plants from growing too densely.
How tall are tomatoes? When the tomato grows to 1-2 meters, it can be topped and topped, the lateral branches need to be trimmed properly, and the redundant leaves under the inflorescence should be cut off.
What is the toppings of tomatoes? If the topping is too short and the plants do not grow enough upward, the lateral branches may grow very large, and the nutrients are uncoordinated, and the topping is too long, which does not hinder the upward movement of nutrients. From the experience of planting, when the stem has 5-6 ears of fruit, it can be topped. Basically, a single tomato can leave 5-8 ears, the first ear is controlled at 3-4 fruits, and the other ears are controlled at 4-5 fruits.
Don't pick too many leaves when topping tomatoes. Generally 2-3 leaves are better, which can protect the wound from animals or accidental typhoid fever. The fixed leaves can photosynthesis, provide nutrients for the healing of the top and help the healing of the top.
How long can tomatoes grow new leaves after topping? Tomatoes can grow new leaves after topping for a period of time, and the growth rate of tomatoes is still relatively fast. When will the tomatoes be ready? Tomatoes need topping, and topping is generally suitable in May-June in summer, which is when tomatoes grow faster.
Tomato topping method step 1, tomato topping occurs in May and June. The weather is very hot and the light is very strong at this time. At this time, it is best to leave three leaves on the top ear of tomato, which can block the sun for the fruit, avoid sunburn and fruit cracking, and also play a role in nutrient supply.
2. In addition, according to the different tomato planting habits and tomato shaping habits, the methods of topping and coring are also different. For example, tomato plants with single stem pruning method are generally topped when the tomatoes grow to 1.5 meters. Tomatoes with double-dry pruning method can generally be topped and pitted after leaving enough effective ears.
3. The topping method of tomato with multiple topping and branch retention management is relatively simple. Generally, topping can be carried out when the basic branch grows and the two inflorescences grow, and topping can be carried out after the lateral branches grow well to keep the branches strong. Generally, tomatoes with this shaping method can keep 4 fruiting branches.
Precautions for topping tomatoes 1. Reduce root damage, because the more times the seedlings are divided, the more serious the damage to the roots will be, which will easily lead to premature root aging.
2. Avoid the formation of aging seedlings. Too many times of seedling division, the root mass can never be fully expanded and the absorption capacity is weak, which leads to the inhibition of seedling growth due to insufficient nutrient supply. If the seedlings are suppressed for too long, they will form old seedlings.
3. Reduce other injuries to tomato seedlings, such as easy starvation when seedlings divide. Seedling separation during flower bud differentiation will have a bad effect on flower bud differentiation.
