(1) Pay attention to watering after fertilizer and water management, keep the soil moist, loosen the soil and weed after survival, and water the dry land in times of drought. Before germination in early spring every year, human excrement should be topdressing once to promote the growth of spring shoots. Apply it again before the buds form. In order to promote bud differentiation and more pregnant buds. After flowering, phosphorus and potassium fertilizer are applied again, and each plant is applied with 1 ~ 1.5 kg of calcium superphosphate or 0.5 kg of ammonium phosphate granular fertilizer and 0.5 kg of plant ash, which is beneficial to flower protection and fruit expansion. In late autumn and early winter, winter fertilizer can be applied again after defoliation, and each plant can be applied with 15 ~ 20 kg manure, burnt mud ash or garbage fertilizer, and the rhizosphere trunk base should be earthed to keep warm and prevent freezing. Every fertilization should be applied in the open-loop ditch around the root marker and covered with soil. If the soil is dry, it is best to water it after application.

(2) Pruning and shaping should be carried out when the trees are young. When the height of the tree is 80 ~ 100 cm, the top of the trunk should be cut off, which is called topping to promote the growth of branches. After that, several vigorous branches should be selected and cultivated into backbone branches to make them evenly matched, and the rest branches should be cut off to form a crown skeleton. Generally, pruning is mostly carried out in winter, and there are two kinds of pruning: thinning and cutting. Thinning is mainly to cut off branches that are too dense. The pruning method of "three hits one, five hits two" is often adopted, and at the same time, delicate shoots, branches with pests and diseases, and branches that are improperly planted and disturb the tree shape are cut off. Short-cutting is to cut short those branches that grow too strong to inhibit excessive growth and keep the tree balanced and beautiful. When pruning, pay attention to those branches that are full of growth and have oval buds, and leave them to blossom and bear fruit in the next year. Cut branches of pests and diseases should be burned in time.

(3) In the first few years after intercropping, the plants are still small and the gaps between plants are large, so crops such as peanuts, beans or potatoes can be intercropped to improve the land utilization rate and increase income.

(4) After growing in the old garden for a certain number of years, the growth potential of Evodia rutaecarpa gradually weakened and the yield decreased. The trunk is often eaten by insects, which makes the branches hollow, causing the branches to break or die. At this time, the seedlings sprouting from the roots of the old trees can be cut off, pruned again, and carefully cultivated gradually, so that the new Evodia rutaecarpa garden can grow again.
