Seed price and planting method of Radix scrophulariae

Radix scrophulariae, also known as Yuanshen, Black Ginseng, Chongtai, etc., is a tall herb of Scrophulariaceae, which is often born in bamboo forests, streams, jungles and tall grass. It is distributed in Zhejiang, Sichuan, Hubei, Guizhou, Hunan, Jiangxi and other places in China. Its root medicine has the effects of clearing heat and cooling blood, nourishing yin and reducing fire, detoxification and knot. Let's take a look at the seed price and planting method of Scrophulariae.

How much is the seed of Radix scrophulariae per jin?

The price of seeds of Radix scrophulariae is about 3040 yuan per jin, but it varies according to the quality, variety, producing area and market of the seeds. Radix scrophulariae commonly used seed bud, seed, ramet, cuttage and other propagation, generally used seed bud propagation, the seed reproduction rate is low, but the seed reproduction growth is fast, the product can be produced in one year, and the disease is less. In the harvest of Radix scrophulariae, disease-free, robust, white buds with a length of 3 cm and 4 cm were selected to be used as breeding materials from the top and bottom of the Reed head. Winter seeds were used in the south and spring seeds were used in the north.

Sowing method of Radix scrophulariae

1. Sowing time: Radix scrophulariae is planted in the south and divided into spring sowing and autumn sowing, spring sowing is carried out in February, autumn sowing is carried out in October to early November, spring sowing can be harvested in the same year, but the quality is relatively poor, autumn sowing grows fast, and the quality and yield are better than spring sowing.

2. Sowing method: Radix scrophulariae uses sunny border to raise seedlings, and after the border is done, the seeds are sowed evenly or striped, sifted with a sieve, covered with seeds and covered with a layer of straw or wheat straw, which is convenient for moisture conservation and heat preservation.

3. Post-sowing management: remove the cover grass before the seedlings come out, pay attention to moisturizing until the seedlings come out, and often pull the grass. After the seedlings come out, the seedlings should be 2 or 3 times. Because the seedlings are very thin and weak, a small amount of fertilizer should be applied, and the seedlings can be planted to the field when the seedling height is 6 cm.

Planting method of Radix scrophulariae

1. Land selection and preparation: the deep sandy loam is selected for planting Radix scrophulariae, and planted on the sunny hillside of barren hills. it is better to plant legumes and Gramineae in the previous crop. The root of Radix scrophulariae is very deep in the soil and has a strong ability to absorb fertilizer, so it needs deep ploughing and sufficient base fertilizer.

2. Intermediate ploughing and weeding: when there is grass, it is pulled out, but it is not easy to loosen the soil too deep when weeding, so as to avoid harming the root mass. From April to June, there are 3 or 4 times of weeding and weeding. After June, the plant has grown up and no longer need pine, but there is still grass to pull up.

3. Timely topdressing: in addition to applying sufficient base fertilizer, Xuanshen applied phosphorus and potassium fertilizer twice before sealing ridges, and applied some barnyard manure or compost, opened small holes or ditches next to the plant, covered with soil, and cultivated the soil at the root.

4. Reasonable seedlings: in the second year after planting, many seedlings will grow from the roots, so that the roots will be expanded, the yield will be increased, and the excess strains will be removed in time, generally leaving only 2-3 strains.

5. timely topping: Scrophularia will bolt when it grows to a certain extent, and if it is used as a commercial harvest, it will not be used as a seed, so that the nutrients will be concentrated in the root tuber and promote the root production and expansion.

6. Watering and drainage: Radix scrophulariae is more resistant to drought and not resistant to waterlogging. When the drought is particularly serious, it is appropriate to pour water to make the soil moist, but it is not easy to flood, and rainy water should be drained in time during the rainy season.

Disease and insect control of Radix scrophulariae

1. Spot blight

[harm] the rainy season is more serious, which occurs widely in the north and south, and the leaves die in the heavy ones.

[prevention and treatment] before and at the initial stage of the disease, spray 1-100 Bordeaux solution or 65% Dyson zinc 500-fold solution, once every 7 days and 10 days.

2. White silk disease

[harm] damage to roots and rhizomes, disease occurred from June to September, Rain Water was often serious, the roots rotted, and the diseased plants wilted and withered rapidly.

[control] before planting, use 1000 times vacuoles of 50% bacilli for 5 minutes and then dry and plant.

3. Ground tiger

[harm] harms the roots and buds of Radix scrophulariae.

[prevention and control] 100 grams of methomyl EC and 1 kg of water can be diluted and sprayed on 100 kg of fresh grass or vegetables to become poison bait.

4. Red spider

[harm] harms the leaves, causing white spots, yellow leaves and drying up.

[prevention and treatment] at the initial stage of the disease, 0.2-0.3 degree stone-sulfur mixture was sprayed to prevent and cure the disease.
