Measures taken: control the amount of fertilizer, adjust the types of fertilizer, reduce the amount of nitrogen fertilizer and increase some phosphorus and potassium fertilizers, among which ternary compound fertilizer is commonly used. At the same time, a small amount of fertilizer containing trace elements should be added appropriately, and it is best to apply less chemical fertilizer and more organic fertilizer. You can directly buy and process organic fertilizer, humic acid water-soluble fertilizer, flowers and so on. Especially in the fruit-bearing period, it can make the fruit bigger and the pulp fragrant.
2. Insufficient light: Ficus carica is a fruit tree that likes light. Compared with ground planting, potted figs always have some defects, because indoor lighting itself is limited by space and time, which is not enough. If not, let's take a look at the location again and see if the lighting time is very short. If fig trees are kept in a place with insufficient light for a long time, it is easy to cause thin branches, overgrowth or malnutrition, and it will also cause no fruit.
Measures taken: put it in the strongest and most abundant place on the balcony to ensure that the light is not less than 6 hours a day.
3. Pruning branches is not in place: figs grow rapidly. If the pruning is not in place and not in time, it will cause insufficient light and ventilation, then the fig tree will only grow leaves and will not bear fruit. Some friends are unwilling to prune in order to bear more fruits, which will only cause the fig tree to be closed, lack of light, poor ventilation and light transmission, and the branches grow too fast. All nutrients are used to grow branches, which will inhibit the transformation to reproductive growth, and then lead to the failure of long branches.
Measures taken: timely pruning. We'd better use "happy" potted plants. The method is simple. Cut the trunk into 40-50 cm to make side branches, leaving three thick side branches. Each side branch is cut and pulled out again. This pruning can not only control the height of the tree, but also has good ventilation and light transmission, and does not occupy space. Pay attention not to leave too many branches in each branch group, mainly the branches under the back. The newly grown branches should be picked in time to promote the transformation from vegetative growth to reproductive growth.
Extended data:
Figs bear fruit in two seasons. The first season is spring fruit, which basically grows when it sprouts, and the second season is autumn fruit, which grows in the axillary bud position with the growth of new branches. The main consumption of fruit in spring is the growth of nutrients accumulated by trees last autumn. If the nutrients were not accumulated enough last autumn, the fruit would fall easily. Autumn fruit relies on photosynthesis of leaves to provide nutrients. As long as the temperature is suitable, it will mature smoothly.
The name of fig was named because of the careless mistakes of the ancients. In fact, there is no fruit without flowers. Flowers are organs of sexual reproduction of plants, and they will not be "flowery but not real" or "solid but not flowery". Of course, solid fig trees naturally have flowers.
