How to plant Fritillaria thunbergii

Fritillaria thunbergii has a long history in China, and it is a famous kind of traditional Chinese medicine. Fritillaria pinnatifida sells very well in the market, which must be mainly due to its effectiveness. So now many people want to plant Fritillaria thunbergii, but before planting, how much do you know about its planting technology?

How to plant Fritillaria thunbergii

1. Land selection: the cultivated plots of Fritillaria thunbergii should choose fertile soil with flat topography and good drainage, such as mountain black soil, oil sand, and land not suitable for yellow soil, especially waterlogged land.

2. Soil preparation: the soil preparation of Fritillaria thunbergii is cultivated first and then cultivated, and other crops are interplanted at the same time. The specific method is to strike ridges in spring, need two ploughs and one ridge, and flatten the ridge tip with a rake after ridging, so as to increase the thickness of furrow soil layer. The ridge can cultivate grain or cash crops normally, and the ridge can be reserved for the cultivation of Fritillaria thunbergii.

3. Cultivation time: start cultivation after planting and harvest, no more than one month at the latest, cultivation is too late, which affects the differentiation of underground regeneration buds in the current year and the emergence rate of seedlings in the coming year. The specific time is from mid-June to early-mid-July.

4. Planting method: shovel the soil in the furrow to about 3 cm, 20-30 cm, sow the seed into the ditch, and then cover the soil, usually with the soil on the second ridge to cover the first furrow, in this order, the thickness of the covered soil is about 3 cm. Finally, it is evenly covered with rotten farm manure (pig manure, cow manure, sheep manure, deer manure and horse manure, etc.) with a thickness of about 1.5-2 cm. In the past, the cultivation of Pingbei had the habit of applying bottom fertilizer, but in recent years, it was easy to appear in the case of high temperature and drought, such as fever and electric crack, which affected the seedling preservation rate. The cultivation of Fritillaria thunbergii plot nutrients can not only preserve soil moisture, but also improve the soil structure, which is beneficial to the high yield of Fritillaria thunbergii.

Planting technique of Fritillaria thunbergii

1. Seed planting. Choose to grow 4-5 years strong plants, usually to strengthen the fertilizer and water management system, and insert some Artemisia sticks or branches next to the plant as a frame, so that the tendrils climb on them, so as to avoid wind break. It blossoms and bears fruit in May, and the aboveground plants gradually wither in late May (Lesser Fullness of Grain), but the fruit is not yet ripe, so you can put it away with the fruit and store it in a ventilated place for later ripening, pay attention to mildew prevention. Dry until the fruit changes from green to yellow, when the fruit cracks, pick the fruit and rub out the seeds to be sown.

2. Cultivation methods. After applying the bottom fertilizer and laying the border soil, the cultivation was planted with horizontal strips, the row spacing between large and medium shellfish was 5 cm, the plant spacing was 5 cm, the row spacing of Beckham was 5 cm, and the plant spacing was 3 cm. After sowing and planting, 4cm humus soil will be covered according to the planting size, and then hold flat. Then cover the bed with 2cm cover dung to ensure that the soil is loose, maintain moisture, increase soil fertility, alleviate the change of soil temperature, and protect Fritillaria thunbergii safely through the winter.

Why is Fritillaria pinnata rich in water?

1. Fertilization: from the beginning of winter every year, barnyard manure with a thickness of about 3cm should be covered on the border surface to play the dual role of fertilization and heat preservation and cold protection, which can promote early emergence of seedlings. Winter manure often uses pigsty manure, mule manure and green manure. Cow dung is prone to worms and poor fertilizer efficiency, so it is generally not used. Plant ash, Kang cave soil and other alkaline fertilizers are easy to cause Fritillaria rot, which is strictly prohibited.

2. Watering: the spring drought should be watered in time so as not to affect the emergence of seedlings, and watering depends on the weather after emergence. After watering, the soil is easy to harden and should be loosened in time; when the rainy season comes, it is necessary to dig a ditch to eliminate stagnant water so as to prevent Fritillaria from rotting.

Common insect pests of Fritillaria thunbergii and their control

1. Rust. Control methods: clear the garden and eliminate weeds and diseased bodies in the field. Spray 300 times of rust sodium solution before flowering, once every 7 days.

2.Sclerotinia sclerotiorum. Prevention and control methods: crop rotation, selecting high border planting with good drainage, and strengthening field management. The fertilizer should be rotten. Pull out the diseased plant and disinfect the acupoint with lime in time. The root was irrigated with 1000 times of carbendazim. Seeds are used to propagate in areas with serious disease to prevent seed planting from carrying bacteria.

When planting Fritillaria, we must do a good job of site selection, and then plant it at the right time, and the distance depends on the planting distance. After planting, it is also necessary to strengthen the management of fertilizer, water, insect pests and so on. Only by doing these well can its growth be guaranteed.
