Seed price and planting method of seven leaves and one flower

A flower with seven leaves is also known as Hua Chong Lou, seven leaf lotus, iron lamp stand and so on. it is a herb of the family Liliaceae, born under hillside forests and in shady and humid places of thickets, and distributed in Xizang, Yunnan, Sichuan, Guizhou and other places in China. Rhizome medicine has the effects of heat-clearing and detoxification, detumescence and pain, drying the liver and calming the liver. Let's take a look at the seed price and planting method of the seven-leaf flower.

How much is a flower seed with seven leaves per jin?

The price of seven leaves and one flower seed is about 500 yuan to 600 yuan per jin, but it varies greatly due to seed quality, purchase time, purchase market and so on. The seven-leaf flower likes temperature, humidity and shade, but it is also resistant to cold and drought, afraid of frost and sunlight, and likes to be planted in sand and loam with high contents of organic matter and humus, especially in riverside, riverside and back shade mountain. Seed planting is the main method in production, and direct seeding is usually best used, but seed breeding and transplanting can also be used in order to save seeds and dense planting and high yield.

The sowing method of seven leaves and one flower

1. Direct broadcast in the field: after the direct broadcast of seven leaves and one flower in the middle and late May, the row spacing is 30cm 35cm, the plant spacing is 20cm 25cm, the depth is 3cm, the narrow moisture is 130cm, and the soil moisture is 150cm. The seeds were soaked in cold for 24 hours before sowing, and sowed with plant ash. 2-3 seeds were planted in each pond. After sowing, the fertile soil covered with fine manure and fine soil was 2-3 cm. The dry soil should be watered in time and germinated in 7-10 days.

2. Seedling raising and transplanting: seven leaves and one branch flower seedling transplant in early April in dry land or vegetable garden with water. Before digging the soil, it is best to disinfect the soil first, and then dig the surface soil layer repeatedly. After leveling the soil surface and opening a sowing ditch about 5 cm deep according to the row spacing of 15 cm, sowing in the ditch according to the plant spacing of 5 cm, then covering the soil with 3 cm, covering fine dung 2 cm, watering thoroughly and covering the plastic film. The seedlings can emerge in 7 days, and the seedlings will be transplanted to the field according to the direct seeding specifications after raising seedlings for one month.

The planting method of seven leaves and one flower

The main results are as follows: 1. Seedling replenishment: seven leaves and one flower were carried out in the direct seeding field in the middle and last ten days of May, while checking the pond to make up for the deficiency. Before the seedlings should be watered, the seedlings should be pried with wooden sticks, and the root water should be watered when replenishing the seedlings, so as to make full use of the seedlings to ensure the whole seedling and sufficient density.

2. Weeding in middle ploughing: the growth of the aboveground part of the flower with seven leaves is weak, so we should pay special attention to loosening the soil and weeding, weeding and loosening the soil in time after seedling or transplanting, so as to do frequent hoe and shallow hoe to avoid root injury and affect growth.

3. Rational fertilization: the basic fertilizer of seven leaves and one flower accounts for 70.80% of the total fertilizer, and the amount of topdressing in the later stage can only account for about 20% of the total fertilizer. After the seedlings are unearthed every year, human fecal water is applied once, no or less chemical fertilizer is used, and chemical nitrogen fertilizer is prohibited.

4. Watering and drainage: seven leaves and one flower like a wet environment, the border surface and soil layer should be kept moist, watering in time in dry season, spraying water at regular intervals, and timely ditch drainage in rainy season to prevent diseases caused by stagnant water in the field.

5. Cutting off the flower bolts: in order to reduce the nutrient consumption and supply the nutrients to the underground tuber growth when planting the seven leaves and one branch flower, when the flower bolts appear from May to June, all the flowers should be cut off in time to increase the yield.

6. Shading management: the transmittance of 40-50% for the whole growth period of seven leaves and one flower is better. Shading measures should be taken after emergence and transplanting. Shading net should be used in places with conditions, and shading with branches can be adopted in places without conditions.

Disease and pest control of seven leaves and one flower

1. Blight disease:

[harm] is a disease in the seedling stage, which is serious in low temperature and rainy days from April to May. At the initial stage of the disease, yellowish-brown watery spots appear at the base of the stem of the seedlings, and spread around the base, causing the seedlings to wither, and in serious cases, the seedlings die and fall.

[prevention and treatment] strengthen field management, carry out soil disinfection, pull out diseased seedlings after the disease, disinfect the seedling bed and spray Dysen zinc solution.

2. Sclerotinia disease

[harm] the disease occurred in May every year when the rain was high and humid, and the base was damaged by soft rot, followed by white filaments, followed by black-brown particles around the disease, and finally the whole plant died and lodged.

[prevention and control] clear the ditch and drain in time to reduce the humidity in the field. Remove the diseased plant in time and spread lime in the disease center. The pesticide topiramate or procuril was sprayed for 2 or 3 times, and in severe cases, chlorothalonil was sprayed.

3. Black spot

[harm] the disease starts from the leaf tip or leaf base, producing round or subcircular spots, and sometimes the disease spreads to the flower axis, resulting in leaf blight and stem blight.

[prevention and treatment] pay attention to drainage and dehumidification, reduce air humidity, reduce the incidence of the disease, and spray 5% bacteriological detergent or 50% methyl thiophanate suspension at the initial stage of the disease.

4. Stem rot

Most of the damage occurred in the seedbed stage, and the harm was more serious in the high temperature and rainy field stage. Firstly, the yellow-brown disease spot appeared at the base of the stem. After the disease spot enlarged, the leaf tip lost and sagged under the water, and in severe cases, the stem base wet rot fell.

[prevention and treatment] 50% carbendazim wettable powder was sprayed on the seedling bed before transplanting, and 95% dimethazone wettable powder was used to irrigate the pond at the initial stage of the disease, once every 10 days, continuous irrigation for 2 or 3 times.

5. Beetles

[harm] the adults harm the leaves, bite the roots with the larvae, and affect the plant growth.

[control] at night, torches are used to trap and kill adults, and trichlorfon is sprayed with fresh vegetable leaves to trap and kill larvae.
