Where is the main production area of star anise? How do you raise seedlings when planting?

The main production area of star anise in China is planted in Guangxi, Taiwan, Fujian, Guangdong, Guizhou, Yunnan, Zhejiang and other provinces. Among them, Guangxi is the main production area of star anise. The selection of octagonal nursery land should first consider the principle of on-site seedling cultivation and convenient transportation.

The garden should be at the foot of the mountain or on a gentle slope, preferably freshly opened. It is best to cultivate the soil of bare-root seedlings with a certain degree of sandiness, and the soil for seedlings is loose, so that the damage to the root system of seedlings will not be too great. You can also use seedling cups to raise star anise seedlings.

The main production areas of star anise are in Guizhou, Yunnan, Guangdong, Fujian and Guangxi; Choose a very suitable soil, preferably sandy soil, remove the long grass, then make the drainage ditch, apply the base fertilizer, and then you can raise the seedlings.

For anise, its main production area is Napo County in Guangxi; When planting, you must choose high-quality varieties, and pay attention to the relevant fertilization, watering treatment, and also choose fertile and loose soil.

Star anise is a well-known condiment, the main production area of star anise is in Guangxi, you must pay attention to moisture, sunlight and temperature when planting seedlings.

It is not recommended to plant star anise in the northern region, because star anise is suitable for growing in the environment of 20 30, and the average annual temperature in winter in the northern region is below 0, so it is not recommended to plant star anise in the northern region. In the process of growing the anise tree, it needs to be watered with unpolluted river water or natural water, and applied well-rotted organic fertilizer to make it grow vigorously.

The north can not plant star anise, because the star anise tree is suitable for growing in the environment of 20 30, in more than 10 can be successfully wintered, and the winter temperature in the north is below 0, the growth rate of star anise will be relatively slow, and need to do a good job of keeping warm measures to make star anise smoothly overwinter, so it is not recommended to plant star anise in the north region, and it is recommended to choose the warm area in the south when planting star anise.

The anise tree is suitable for living in a humid environment, and during the growth of the anise tree, it can be watered with unpolluted river water or natural water to ensure that the soil is in a slightly moist state. When watering, water should be poured directly on the soil to avoid direct contact with the leaves of the anise tree.

In the growth process of the anise tree, it is also necessary to ensure the sufficiency of nutrients, so in the process of maintenance, it is necessary to apply phosphorus and potassium fertilizer or well-rotted farm fertilizer to supplement nutrients during the vigorous growth period of the star anise tree. During the flowering and fruiting period of the star anise tree, nitrogen, phosphorus and potassium fertilizers are mainly inorganic fertilizers to improve the yield of the star anise tree.

In the growth process of the anise tree, it is also necessary to prune it properly, choose sharp scissors when pruning, sterilize and disinfect with alcohol, and cut off the poorly growing branches on the anise tree to reduce the consumption of nutrients. You can also cut off the branches that grow too densely on the anise tree to improve the ventilation and light transmission of the anise tree.

Seedling breeding method of star anise.

1, seed collection: the selection of excellent varieties, generally choose 20-50 years old, vigorous growth, high yield of the robust mother tree as the object of collection, in mid to late October star anise fruit from green to yellow, the fruit petals have not yet cracked when the fruit can be picked, and the small fruit, achene, irregular fruit removal, tree selection and fruit selection, good varieties and strong seedlings are the basis for octagonal afforestation to obtain high yield and high yield, where too early or too late to collect the fruit, its seed quality is poor, not suitable for seeding.

2. Seed treatment: The fruits recovered by the star anise are spread indoors to dry, turned 1-2 times a day to prevent them from heating, and the corners of the shed can be collected after 3-4 days, and the seeds can also be peeled with a knife or a thin wood chip knife (do not hurt the seed coat). In areas without frost, it is advisable to collect and sow with seeds.

If you choose to sow in the spring, you should do a good job of thermal insulation and moisturizing, generally to choose fine sand for sand storage, if you need to transport far, then use fine sand seeds for the proportion of 5 1 packed into a box and consigned to the destination after pouring out and putting it into the indoor shade drying, with the method of sand storage for thermal insulation and moisturizing, when the temperature rises to 10-15, you can carry out sowing seedlings.

3. Land selection: Octagonal nursery land is better to choose a well-drained, fertile and deep yellow mud mountain, leave about 30 cm of sidewalk between the furrows, dig 17-20 cm high, 18-20 cm deep, 1 meter wide furrow, apply turf marl or compost tons of hectares.

4, sowing method: generally for frost-free areas, chain pure choice in December to January of the following year into the forest sowing is better, frost areas, should wait for the temperature to rise to more than 12 when the sowing in 2-3 months as well, it is advisable to choose the strip sowing method, the plant spacing of the furrow is 2-3 cm, the depth is 3-4 cm, the row spacing is 15-20 cm, the sowing amount is generally 90-120 kg hectares, after sowing cover the burned turf mud, mixed with centimeters of yellow fine mud, and then cover 1 layer of thatch and drenched with water.
