Do star anise trees have leaves all year round

The leaf life span of star anise trees is generally l 3 years, the leaf life span of young trees and strong trees is longer, and the leaf life span of old trees and diseased trees is shorter. Taking appropriate measures to preserve leaves is of great significance for tree growth and yield improvement.

Scientific fertilization. Constant, medium and trace organic compound fertilizers are beneficial to leaf growth, and can strengthen leaves, that is, the leaves are thick and green; It can protect the leaves, that is, prolong the life of the leaves. The leaves of single application of yuan or ternary inorganic compound fertilizer are green but not thick or thick.

Proper fertilization. According to the growth characteristics of the star anise tree, fertilization should be based on shallow application, diligent and thin application, maintain nutrient balance throughout the year**, avoid deep furrow fertilization, avoid heavy fertilizer, and avoid fertilization in the case of drought and water shortage, otherwise it will cause leaf decline or cause defoliation due to root impact.

3. Spray foliar fertilizer. Foliar fertilizer has a significant effect on strengthening leaves and preserving leaves, especially in winter and spring when defoliation is more serious, spraying 2 or 3 times of foliar fertilizer can reduce defoliation. Foliar fertilizer should be mainly organic or compound type, such as Gaomeishi, Xinzhixin, Feiba, etc.

4. Strictly control the number and amount of inhibitory hormones. Most inhibitory hormones have a definite effect on flower promotion, flower preservation, and fruit preservation, but they also have certain damage to leaves, so they should be used with caution. Generally, the number of times of use throughout the year should not exceed 3 times, and the concentration should also be strictly controlled, and the amount of wine sprayed should be sprayed until the leaves are moist but not dripping.

It is best to add foliar fertilizer and spray to reduce the degree of damage to the leaves.

Yes, the octagonal tree is an arbor with a height of about 10-15 meters and a tower-shaped crown. Leaves: The leaves of the anise tree are generally alternate or spiral-arranged, with obovate-oval or inverted-lanceolate shapes and a dark green surface.

Flowers: The flowers of the anise tree are solitary in the leaf axils and are pink or crimson in color. Fruit:

The aggregate fruit is radiating in the shape of a star and is reddish-brown in color. Seeds: The seeds are oblate-oval in shape, reddish-brown or gray-brown in color, and shiny.

Hello, the octagonal tree does not bear fruit in the following situations: 1 is that the nutrient storage in the tree in the early stage of the ulnar core is insufficient, there is not enough nutrients for the octagonal tree to bloom and bear fruit, it needs to be supplemented with nutrients in time, and then bloom and bear fruit in the next year; 2. The octagonal tree flowering and fruiting caused by the poor development of the flower's organs and the fact that the pollen tube does not extend into the ovary are caused by the digging of the lingkey, and there is no good way to remedy the bright sun.

Planting anise trees in the field will bear fruit.

The shortest fruiting time of star anise tree planting is 3-4 years, the longest is 5-8 years, afforestation 8-18 years, and 6-15 years of fast harvest forest is the first fruit period of the middle and young age of star anise, starting from 19 years of life, and the fast growth of the forest from 16 years to the full fruit period of plant senescence for star anise, under normal circumstances, the full fruit period of the soft branch type of star anise can be as long as 60-70 years, and the full fruit period of the hard branch type is 40-50 years.

The initial stage also needs basic inputs, including land, management, labor, etc., the initial yield of octagonal is not high, the general yield of autumn fruit per mu is about 1000 kg, according to the current market yield of tens of thousands of yuan, but the planting situation in each region is different, the purchase price of octagonal land may be lower.

The anise tree does not bear fruit when it blooms.

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

2. Woodland hoeing: hoeing and reclamation of woodland to increase soil permeability and promote the germination of new roots, the woodland with a slope of less than 25 degrees can be fully reclaimed, and the woodland with a slope of more than 25 degrees should be reclaimed.

3. Reasonable dense planting: It is advisable to maintain 30-45 trees per mu and the crown interval of mature forest plants is 1-2 meters, and the principle of removing the inferior and leaving the good, removing the weak and retaining the strong, and going dense and thinning is adopted for reasonable thinning.

4. Reasonable pruning: the trees that are too dense and have less fruit are properly re-pruned, the sparse ones are less pruned or not pruned, the lower part of the crown is properly re-pruned, the middle and upper parts of the crown and the outer edge of the branches are lightly pruned, the growth and development is abnormal, the diseased and insect branches and dry branches are heavily pruned, the healthy light pruning is carried out, and the star anise of the tree is more vigorous and the ring is circumferentially cut.
