How long does the star anise tree species bear fruit?

The shortest fruiting time of star anise tree is 3-4 years and the longest is 5-8 years. 8-18 years of afforestation and 6-15 years of fast-growing forest are the first fruit stage of middle and young star anise, starting from 19 years and from 16 years to the full fruit stage of star anise senescence. Under normal circumstances, the full fruit period of star anise of soft branch type can be as long as 60-70 years, and that of hard branch type is 40-50 years, if all aspects of habitat conditions are superior. It can prolong the full fruit period.

Planting environment of star anise tree

Star anise tree is a negative tree species, which is suitable to be planted on loose and acidic sandy soil with short sunshine time, lush vegetation, deep soil layer, good drainage and rich humus. The north slope of hilly and mountainous area with undulating topography and shelter from wind should be selected for forest management, and the land with deeper soil layer is more loose and more convenient for drainage and irrigation.

The star anise tree blossoms but does not bear fruit

1. Woodland environment: keep the star anise forest ventilated, transparent and clean, remove weeds and shrubs, and avoid competing with star anise for fertilizer and glory.

2. Forest land reclamation: forest land reclamation is carried out in order to increase soil permeability and promote new root germination. Woodland with slope less than 25 degrees can be completely reclaimed, and woodland with slope greater than 25 degrees should be reclaimed.

3. Reasonable close planting: it is appropriate to keep 30-45 plants per mu and the canopy interval of adult plants is 1-2 meters, and to adopt the principles of removing inferior quality, keeping strong, densely retaining and thinning reasonably.

4. Reasonable pruning: heavy pruning is appropriate for trees that are too dense and with little fruit, sparse ones with little or no pruning, proper heavy pruning of inner chamber branches in the lower part of the crown, light pruning of branches in the middle and upper parts of the crown and outer edge, heavy pruning of abnormal growth and development, heavy cutting of disease and insect branches and dry branches, well-developed light shears, and ring cutting of star anise which is more vigorous.

5. Rational fertilization: the amount of fertilizer application is mainly compound fertilizer, about 4 kg per plant, which is applied twice a year according to the actual tree potential, the first time should be from late October to early March of the second year, and the second time is from June to August.

6. Flower and fruit protection: spray anti-falling element and foliar fertilizer during flowering and fruit setting period. When Xiehua is 70-80%, use one package of anti-falling element and one package of potassium dihydrogen phosphate and spray 60kg of water.

7. Prevention and control of diseases and pests: pay attention to inspection in daily management, timely control of diseases and pests, and spray with 500 times dichlorvos or dimethoate every year from March to April and June to July.
