We should use relatively loose, breathable, well-drained and organic sand from the beginning of seedling cultivation. Adequate fertilizer and water supply should be provided during the whole growth period, but it is not advisable to accumulate water in the basin for a long time. It should be in a sunny environment all year round. In addition to the hot sun exposure in summer, other times should also be properly shielded and receive as much light as possible. After the seedlings are planted, two or three main branches should be properly selected, and other messy branches should be trimmed. Short cutting, trunk cutting and branch storage can be used to make the main branches of plants grow more lateral branches. During the whole growth period, these lateral branches grow to a certain length. When there are about 5-6 leaves, the core and top can be removed, so that the bud tips in the axils of the remaining leaves can fully grow and develop. In a year, fruitless plants usually have two leaf bud germination times. Later, when the side branches appeared again, the same method was used to remove the core and the top.

In order to reduce the odor, you can also add some orange peel, which will greatly reduce the odor of nutrient solution. After July and August every year, nutrient solution is often used, and appropriate amount of potassium dihydrogen phosphate can be added to effectively improve the flower bud differentiation ability of plants. When fertilizer, water, light and wind are adequate and suitable, combine with proper pruning and topping. The management of potted citrus reticulata should have sufficient fertilizer, water and light, combined with proper pruning and topping. Can not let its branches grow freely, reluctant to be cut off. Boron fertilizer should be sown before germination. Adult trees are 10g per year, and young trees under 3 years are 5g per year. It is required that the boron fertilizer contains more than pure boron 1 1%.

Add appropriate amount of sand and mix well. Sprinkle evenly on the tree tray. Organic fertilizer and boron fertilizer should not be mixed, because organic fertilizer is divided into dry and wet, and boron fertilizer is difficult to mix evenly. Correctly identify boron fertilizer, so as not to identify the unused pure boron content, the unused pure boron content is lower than 1 1%, the unused manufacturer or manufacturer with unknown address, and the unused trademark boron fertilizer. Flowering and fruiting need a lot of nutrition. Therefore, it is necessary to ensure that citrus has enough light and collect energy through photosynthesis. If there is too little light, citrus will bloom abnormally and bear no fruit.
