Fritillaria thunbergii is a perennial herb of the genus Fritillaria in Liliaceae. Its bulb can be used medicinally because of its shape. How much is the price of Fritillaria in 2020? What are the high-yield planting techniques?

1. How much is the price of Fritillaria in 2020?

As of March 16, the price of Xinjiang Fritillaria in Bozhou Pharmaceutical City is 20 yuan per jin, that of Xinjiang in Anguo market is 22.5 yuan per jin, and that of Huocheng County in Xinjiang Uygur is 31 yuan per jin. The above are all reference prices, and the specific prices are subject to the actual local selling prices.

2. High yield planting techniques of Fritillaria thunbergii

1. Land selection and preparation

Fritillaria thunbergii is a perennial plant. Because the cultivation cycle of Fritillaria is long, the selection of land is one of the keys to cultivation. In the soil, the nutrition is provided by the renewal of the bulb and most fibrous roots, and the soil fertility is consumed in the case of highly close planting.

When planting Fritillaria, humus soil or sandy loam with deep soil layer, loose soil and good drainage should be selected for cultivation. Avoid saline soil and clayey soil. It is better to be close to the water source to facilitate irrigation. The soil is turned deep into 25CM, leveled and raked fine, making a border 1.2m wide, 15CM high, and the ditches on both sides of the border are reserved for drainage. Combined with soil preparation, it is necessary to apply sufficient base fertilizer, 3000-4000 kg of rotten farm manure and 40 kg of superphosphate per mu. The border can be slightly higher in the middle and lower on both sides to prevent stagnant water on the border during the rainy season.

2. Sowing seeds

Fritillaria mostly uses strip sowing. When sowing, first apply 3CM thick farm manure in the ditch, put 3CM thick fine soil, and then put the selected bulb into the fine soil, flatten the fine soil, and then cover the top with 2CM thick mature farm manure as capping fertilizer.

3. Field management

Ploughing and weeding: pull up the grass as soon as there is grass in the field to prevent weeds from competing for water and fertilizer. The depth of weeding is not harmful to the bulb. There were 2 or 3 times of weeding in growing period and wilting period. Before emergence, treatment of soil with 50% atrazine 0.15 kg per mu and 200 kg water can control a variety of annual broad-leaved or Gramineae weeds.

Water management: Fritillaria is a plant in early spring. In case of drought in spring, water should be irrigated once or twice, irrigation should be thoroughly, and soil consolidation should be prevented by loosening the soil. After entering the rainy season, the field should be well drained to prevent the bulb from rotting.

Topdressing: the growth period of Fritillaria is relatively short, so it is necessary to apply quick-acting fertilizer. The leaves were fertilized for the first time before spreading, and 10 kg of ammonium nitrate was applied per mu. The first and middle of May is the peak growing season of Fritillaria thunbergii, which can be applied with calcium superphosphate and diammonium phosphate, watering after fertilization, and loosening the soil in time after water infiltration. Spread 2~3CM barnyard manure on the border in mid-September. It is better to plant Fritillaria with rotten pig manure after withering every winter, and avoid alkaline fertilizers such as Kang cave soil and firewood ash. Capping dung is applied twice a year. The first time before freezing, the application of agricultural fertilizer should be fragile, spread flat on the border surface about 3CM thick; the second time in the summer into summer dormancy after the application of head fertilizer. Attention should be paid to the application of capping fertilizer after sowing.

4. Remove the buds

After the Fritillaria budding, if there is no seed, it should be removed in time. If you want to keep the seed, you can sparse the bud properly. Generally, it is appropriate to keep 1 or 2 flowers per plant. Fritillaria bulb is used as medicine, and removing flower buds can effectively reduce the waste of nutrition and improve the yield and accumulation of effective substances. In the field of Fritillaria without seeds, the buds should be removed in time at the budding stage, and the sooner the buds should be picked, the better.

5. Shading

Fritillaria prefers cool and humid climate. when the temperature reaches 20 ℃ in early June, the aboveground part of the plant dies and the underground bulbs move. During this period, the bulb should complete the formation of regeneration buds, the differentiation of flower buds, the differentiation of axillary bud primordia and the further differentiation and growth of seed shellfish under cool and humid conditions. Therefore, it is necessary to plant shading crops or set up shading nets in time to meet the suitable ecological conditions for a series of differentiation of Fritillaria bulbs.

Shading can prevent the rise of ground temperature and weeds, and improve the field multiple cropping index. Before the plant withered on the ground, corn or beans can be planted on both sides of the border, shade crops can be sown in strips or holes, and sowing should not be too dense or too deep.

Fritillaria thunbergii is a traditional Chinese medicine in China, and artificial cultivation has high economic benefits. Interested growers must understand the local natural conditions before planting, so as to avoid blindly planting and causing losses.
