How to cultivate Fangfeng with High yield

Fangfeng is nicknamed Guan Fangfeng. It is a perennial herb of Umbelliferae, which is used in medicine by root. Mainly produces Heilongjiang, Jilin, Liaoning, Inner Mongolia and other places. The plant height is 50-70 cm. The roots grow strongly and vertically. Wild in grasslands, forest margins, sandy soils. Resistant to cold and drought. Avoid excessive dampness and waterlogging. As wild prices rise year after year. Fangfeng artificial planting has high yield and stable income, so it is a good project for the development of planting.

Cultivation techniques:

Land selection and preparation:

Fangfeng is a deep-rooted plant. During soil preparation, 2000-3000 kg of soil fertilizer and 20 kg of superphosphate must be applied to increase soil fertility and promote root development. Make a 1.3 m wide border or 0.5 m wide ridge and set aside. It is better to plant in large areas by ridging and direct seeding. 2 seed propagation: Fangfeng can be sown in spring, summer, autumn and early winter. Sowing in winter sows before the soil freezes, and seedlings emerge in early spring. For sowing in spring and summer, soak the seeds in 30-40 degrees water for 48 hours, then mix them with three times of wet sand at a suitable temperature for 10-12 days before sowing or sowing when the seeds just open their mouths, sow and compact evenly in the ridges with a depth of 3 centimeters. The sowing amount is about 2.5 jin per mu. In case of drought, it should be watered in time and keep moist during seedling emergence. The suitable row spacing for border planting is 30-35 cm.

Field management:

When the height of the border seedling is 5-6 cm, the seedling should be fixed by 8-10 cm, and when the seedling height is 10-15 cm, the seedling should be fixed by 6-7 cm. 2 weeding and cultivating soil; weeding in time to prevent herbs from growing together, generally sealing ridges in July and August, and applying ammonium carborate 20-25 kg to promote seedlings. When annual Fangfeng growth is small, soil can be cultivated once after autumn to protect roots for overwintering. The following year, manure water is applied, and 20-30 kg of calcium superphosphate is applied to strengthen roots. 3 bolting; annual or biennial growing plants should be removed in time to promote root growth.

Pest control:

1. Powdery mildew was prevented and treated with Baume 0.2-0.3 degree stone sulphur. two。 When pests, choose anti-toxic and pollution-free pesticides to kill insects. Make the product free of pesticide residues in line with the GAP production standards. Harvest processing: autumn and winter harvest, according to the growth situation, the root length is 30 cm, the thickness is more than 1.5 cm, it is harvested when it is too premature, the root is Lignification too late, remove the residual stems and leaves, soil, and remove the fibrous root when the root is semi-dry, and tie it into small handfuls according to the length and thickness. Just dry in the sun. The yield per mu is about 300-500 kg.
