Many vegetable farmers in the cultivation of over-season tomatoes when the use of more fruits in the early stage, leaving 5 to 6 fruit per panicle method, to suppress the tree, inhibit plant growth, promote fruit setting. The results are counterproductive. The nutrition of the lower tomato fruit is more, resulting in insufficient nutrient supply to the upper part of the plant and poor fruit set. Therefore, the vegetable farmer should remove the excess fruit from the lower part of the plant, generally in two separates, the first time when the fruit grows to the bean size, and remove the fruit that is too large, too small or obviously deformed. The second time when it grows to the size of the grape, it is mainly to remove the deformed fruit and reduce the nutrient consumption, so as to promote the upper flowering and fruit setting of the tomato.
Many people think that the summer temperatures are high and they can keep more fruit. In fact, excessive planting of fruit in the lower part of the plant, excessive nutrient consumption, will seriously affect the growth of stems and leaves and roots, resulting in insufficient supply of nutrients absorbed from the soil, less accumulation of photosynthetic products, falling in the trees, and fruiting and fruiting of the late tomato stage. Will be greatly affected.
Suggestion: The first ear does not leave, timely removal. The reasons are as follows: 1. It is easy to fall off the tree, which is not conducive to late high-yield. 2. Due to the high temperature of nursery, the first flower buds are poorly differentiated, and they are prone to malformation in the later period. 3. The first spike flower was used to test the anther concentration, and the appropriate spot flower concentration was tested for the subsequent spikelet flowering. 4. The first flower of each ear is 1 to 2 days earlier than other flowers of the same ear, so the first flower is not. If the first panicle flower is used, the flowers are prone to malnutrition. If the plants are very prosperous, the first panicle should be 2 to 3, the second panicle should be 3 to 4 and the third panicle should be left 4. The fourth panicle or above ear can retain 4 to 5 fruits.
