It is precisely because of the lack of light that photosynthesis cannot be carried out and swollen and developed nutrients cannot be transformed. Orange trees like an environment with plenty of scattered light. If you stay in a dark environment for a long time, it will cause plants to grow in vain and affect the normal flowering of plants. It is necessary to strengthen the illumination of plants and keep them in a well-lit place to avoid strong sunlight in summer.

It is necessary to strengthen the illumination of plants and maintain them in a well-lit place. It may be caused by insufficient nutrition and needs topdressing in time. Phosphorus and potassium fertilizer are mainly applied before flowering. It may be caused by soil discomfort, so it is necessary to change the soil in time and replace it with brand-new soil for re-maintenance. Fertilize in time before and after flowering, and give priority to phosphorus and potassium fertilizer before flowering to ensure that the roots of plants absorb enough nutrients and promote the growth and flowering of plants.

Maintenance of orange trees

Potted citrus reticulata needs frequent pruning in the cultivation process, which can increase the lighting effects. If the branch of the main branch is too long, it can be truncated to avoid the top effect, and a branch can retain about 6 side branches. Because the pot is small, the soil is small and the nutrition is limited. Through pruning, the rational distribution of nutrients in the tree can be adjusted, so that limited nutrients can be supplied to buds and leaves in a concentrated way, and more fruit branches can be formed, thus achieving the purpose of full flowering and fruiting.

When the number of flower buds in orange trees is large, the flowers should be thinned during bud pregnancy and the fruits should be thinned after physiological fruit drop. If there are few buds, you can leave more flowers. At the same time, artificial pollination is to spray water during the flowering period to prevent it from raining during the flowering period. Don't spray water on the blooming flowers, which is not conducive to pollination and is easy to cause rotten flowers. If diseases and insect pests occur in citrus reticulata, it will also cause plants not to bloom. The common disease is anthrax. After discovery, the plants should be sprayed with carbendazim solution in time for control.
