Illicium verum is relatively easy to maintain. Its leaf life is generally1-3 years. Young trees and strong leaves have a longer life span, while old trees and sick leaves have a shorter life span. It is of great significance to take appropriate measures to protect leaves for tree growth and increase yield.
Cultivation method of Illicium verum
The cultivation of Illicium verum L. is to water every 2 ~3 days, spray water on the leaves in summer and autumn, use 50g compound fertilizer of nitrogen, phosphorus and potassium every 15 days, give light all day in spring, autumn and winter, use supplementary light for 2 hours every day in continuous cloudy days, avoid light at noon in summer, and maintain in a ventilated environment to prevent anthrax infection.
1. Humidity:
Illicium verum likes to grow in a humid mountain climate, which requires a lot of water. Generally, the annual rainfall is required to be 1000-2,000mm, and it is required to be evenly distributed. According to the general records of the producing areas, more than 80% of the rainfall is concentrated in May-September, and less in1-3 months, only about 50cm per month.
2. Terrain:
Terrain has a great influence on the growth of Illicium verum, because it is directly related to sunshine, temperature, humidity, rainfall, soil physical and chemical properties and soil depth, and these factors are closely related to the development of Illicium verum. From a large terrain, the mountainous area with overlapping mountains is the best place for Illicium verum to grow, because it has the environmental conditions needed for Illicium verum to grow, such as humidity, low wind and less sunshine, which are not available in low mountains and platform areas.
3. Trim:
The young Illicium verum has strong apical dominance. When the young forest grows to 2_4 years, it is generally as high as 1.8_2 meters, so it should be cut off to promote its branching, and the branch structure should be reasonable. The upper and lower branches should be staggered and empty, so as to ensure good ventilation and light transmittance of the tree. Its branches and leaves have strong germination ability, and it is suitable to cut off some long branches, pests and diseases every winter.
4. Soil:
Illicium verum likes to grow in loose, moist and well-ventilated soil. In dry or over-watered soil with poor ventilation, it grows poorly, and the place with too shallow soil layer is unfavorable for its growth. Because Illicium verum bears fruit all the year round and flowers in half a year, the soil is required to have sufficient nutrients and water. Sandy loam with rich humus content, loose and good structure in forest land is the best.
Matters needing attention in the maintenance of octagonal wood
Care should be taken to prevent the Illicium verum from suffering from anthracnose. In daily maintenance, the maintenance environment needs frequent ventilation. Once it is found to be infected, the infected branches should be cut off immediately, and the whole plant should be sprayed with 400 times solution of 80% wettable powder of benomyl, and then sprayed with 50% benomyl 1500 times solution once a week for one month.
