Planting techniques of Fritillaria thunbergii

Fritillaria thunbergii, also known as Pingbei, is a perennial herb, its bulb can be used as medicine, with heat-clearing and lung-moistening, antitussive and phlegm-relieving effects. Due to the lack of wild resources, there are also artificial planting, some farmers through planting it to achieve prosperity, so how to plant Fritillaria thunbergii? Let's get to know it.

1. Land selection and preparation

Wild Fritillaria prefers a cold and humid climate and generally grows under early forests or in loose, fertile, humus-rich soil on the banks of rivers. Therefore, artificial planting should choose fertile and loose sandy loam, while clay loam, sandy land and low-lying land should not be planted, so as not to affect its growth. In the first year of autumn and winter, the soil is turned deep about 20 cm, and basic fertilizer is applied at the same time. Generally, 4000-5000 kg of rotten farm manure is applied per mu. After mixing it evenly with the soil, the plastic rake is used to make the bed ready.

2. Methods of reproduction

The reproduction of Fritillaria thunbergii is mainly through seed reproduction and bulb reproduction, and bulb reproduction is generally used in production. The number of years of seed reproduction is longer and too time-consuming. The bulbs are harvested every summer from June to July, large ones are used for medicine and small and medium-sized ones are planted on the border surface after autumn according to the row spacing of 1.5 cm, while the trumpet is trenched on the border surface and scattered evenly into the ditch.

3. Field management

Before seedling emergence in early spring, the field should be cleared in time to facilitate seedling emergence, and after seedling emergence, it is necessary to loosen the soil and weed in time, so that there are no weeds in the field and promote the growth of seedlings, especially in summer, when weeds are overgrown, it is necessary to avoid competing with seedlings for water and fertilizer. In order to achieve high yield and high yield, fertilization is essential. From the beginning of every winter, the border should be covered with a layer of 3 cm thick mature farm manure, which plays the role of fertilization and heat preservation and cold protection. In the spring and summer drought should be timely watering, to keep the soil moist, in order to facilitate seedling emergence. After emergence, the soil should be watered according to the dry and wet soil and weather conditions, and the soil should be loosened in time after watering, so as not to harden the soil and be disadvantageous to root growth.

4. Diseases and insect pests

During the cultivation of Fritillaria thunbergii, rust and Sclerotinia sclerotiorum are mainly harmed. Rust usually occurs in April, which leads to perforation of leaves, withering leaves and withering plants; the control method is to clear the garden thoroughly, eliminate weeds and diseased plants, and spray sodium rust before flowering. The effect is better. Balanced bar mainly harms the bulb, when the disease occurs, the bulb appears black spots, which seriously causes the whole bulb to blacken and the aboveground plants wither and yellow. the prevention and control methods endanger reasonable crop rotation, select plots with good drainage, and remove the diseased plants in time when the disease occurs. Lime disinfection was applied to the disease holes, and the surrounding plants were irrigated with carbendazim.

The above is the introduction of planting technology of Fritillaria thunbergii. I hope it can help you. If you want to know more about it, please follow us.
