Cultivation techniques of Illicium verum with high yield and good quality

Star anise is a very good seasoning, which is often used in various seafood or aquatic products. It can be paired with a very good taste. Cooking can increase the aroma of dishes and make people more appetizing. So there is a great demand for star anise in the market. So what methods should we master to grow high-yield star anise?

1, land selection

Illicium verum is a shade-loving crop, which is most suitable for planting Illicium verum in the leeward position. The soil is loose and deep, rich in humus, and the slope is slightly acidic, so as to produce high-quality Illicium verum and improve the yield.

Step 2 plant

Illicium verum is planted in winter and spring, preferably when it rains. Before planting, yellow soil must be used as pulp, properly drained, stirred into paste and made into pulp roots. After the pulp penetrates the roots, complete the planting in time, keep the seedlings planted correctly, keep the roots stretched, do not go against the mountain, plant deeply, tamp by layers, prevent the roots from nesting, and replant them in time when missing seedlings are found.

3, intertillage weeding

In the process of Illicium verum planting, if weeds appear, intertillage weeding should be carried out in time to reduce the consumption of water and nutrients. At least 1-2 intertillage weeding should be carried out in octagonal garden every year, 1-February 1 time, and may-June1time, and chemical weeding can also be carried out with herbicides.

4. Fertilization management

Illicium verum must strengthen fertilization management to maintain nutrient balance in the body and achieve the goal of high and stable yield. It is necessary to scientifically prepare nutrient requirements and apply fertilizer reasonably to meet the needs of reproductive growth and nutritional growth of Illicium verum, and the amount of fertilizer applied and the ratio of fertilizer are different. Spring fertilizer and summer fertilizer promote the vigorous growth of Illicium verum, and Woye high nitrogen water-soluble fertilizer is the main fertilizer, and water-soluble fertilizer can be applied in the later stage.

5, pest control

Illicium verum is prone to spot blight and red wax scale, so it is necessary to strengthen planting management and reduce the source of overwintering bacteria. After the onset, the red wax scale can be killed by spraying Bordeaux solution or 65% zineb 500 times solution and using 0.2-0.3 degree sulfur mixed solution.
