Illicium anise, also known as star anise, anise, etc., is a plant of the genus Illicium in the family Illicaceae. The fruit is a well-known spice and is also used for medicinal purposes. The peel, seeds and leaves all contain aromatic oils and are important raw materials for the manufacture of cosmetics, liqueur, beer and food industries. Now they are mainly distributed in Fujian, Guangxi and other places. Due to the continuous development of the value of octagonal anise, more and more farmers are planting saplings. So how to plant and manage octagonal saplings?

1. Land selection and preparation

When planting anise, you should try to choose hilly or mountainous areas with higher altitudes, warmth and wind protection, convenient irrigation, short sunlight, and no frost damage. When the anise seedlings first come out, they are most afraid of strong light. They should be planted in a plot with shade. The branches of the anise are relatively fragile. After the plot is selected, it must be sorted in advance and the surrounding weeds must be cleaned up before sowing. Clean and organize before planting.

2. Sowing time

Generally speaking, star anise is more suitable for sowing between December and January of the following year, but in areas with spring cold and frost, the sowing date can be postponed appropriately. You can wait until the freezing period in February to March is over and the temperature is stable above 12-15 degrees before germination and sowing.

3. Sowing method

In the management of octagonal seedbeds, the borders can be made according to the ratio of 1 meter wide and 15-20 cm high, 3-4 cm deep and 15- The method of strip sowing is 20 cm and the distance between plants is 2-3 cm. The amount of sowing per acre is about 7 kg. After the seeds are sown evenly, sprinkle a thin layer of plant ash about 1.5-2 cm thick (mixed with plant ash is better), and then pour water once to moisturize. In order to prevent the rainwater on the hillside from washing out the seeds and seedlings, it is best to cover them with a layer of crushed straw or a layer of film after spreading them. This can not only improve the heat preservation and moisturizing performance of the seedbed, but also prevent the seedlings from being washed out by rainwater. Wash out the*.

4. Post-emergence management

After the anise seeds germinate*, the straw, straw and other coverings covering the seedbed should be removed in time, and shade should be built in a north-south direction. A shed (about 70 cm high in the south and about 100 cm high in the north), the light transmittance of the shed should be about 30-40%, otherwise the exposed anise seedlings will be exposed to direct sunlight for a long time and cause wilting or burns and death.

In addition, after the star anise sprouts, attention should be paid to keeping the seedbed border always moist to prevent the seedlings from dehydration and wilting. Generally, there is no need to water too frequently during the seedling stage. As long as the seedbed is not dry, watering is not necessary. If the seedbed is short of water and drought, you can pour small amounts of water in the morning or evening to keep the border surface moist. You can also use urea water or Diluted human feces and urine.

During the growth of seedlings, you can apply thin fertilizer once when the seedlings are 3-5 cm high and 10-15 cm high according to the moisture content and seedling potential. The top-dressing fertilizers are human excrement and cake fertilizer. Or mainly use quick-acting nitrogen fertilizer to promote seedling growth. At the same time, attention should be paid to regular shallow plowing and weeding during the seedling stage.

The above are the key points of planting technology and management of octagonal saplings. When planting octagonal saplings, attention should be paid to cultivating and weeding, shading and moisturizing, pruning branches, and preventing and controlling pests and diseases. In addition, star anise likes a moist environment away from light, so pay attention to shade and sun protection, and avoid direct sunlight. If pests and diseases are found, pesticides should be used for early control in time.
