The price and planting method of dried seeds

Belamcanda Belamcanda is a perennial herb of Belamcanda genus of Iris family. It is distributed in tropical, subtropical and temperate regions all over the world. Its rhizome is medicinal. It can clear away heat and detoxify, eliminate inflammation, reduce swelling and pain, relieve cough and phlegm, and is used to treat tonsillitis and lumbago. Let's take a look at the price and planting method of Belamcanda Belamcanda seeds.

How much is a kilo of Belamcanda seeds?

The price of Belamcanda chinensis seeds is about 80~120 yuan per catty, but the price varies greatly due to the quality, variety, origin and market of seeds. The germination rate of seeds is 90%. The germination begins at 10~14℃, the optimum temperature is 20~25℃, and the germination decreases at 30℃. But the seed reproduction emergence is slow, not neat, lasting about 50 days.

Sowing method of Belamcanda chinensis

1. Seed collection: Belamcanda chinensis usually cuts off the fruit stalk when the shell turns yellow from late September to early October, and puts it in an indoor ventilated place to dry and thresh it. If the seeds are stored in wet sand after harvest, the germination rate is high and fast, but if the seeds are dried after harvest, the germination rate is slow.

2, seed treatment: Belamcanda chinensis seeds soaked in water for a week before sowing, after removing the empty shriveled particles, remove the water, put in the basket with a sack cover tightly, often drench water to keep wet, the temperature at 20℃ about 15 days began to show white buds, a week later 60% of the buds can be sown.

3. Sowing method: direct seeding and seedling transplanting can be used for seed reproduction of Belamcanda chinensis, and the sowing time is different due to open field and plastic film mulching.

① Open field direct seeding: spring sowing is carried out before and after Qingming, autumn sowing is carried out from September to October, trenching and fixing holes are carried out on the prepared ridge surface, soil miscellaneous fertilizer is applied, fine soil is covered, 5~6 seeds which have been promoted to bud are sown, soil covering is compacted, watering, grass covering is used for moisture preservation, and the seed amount per mu is 2~3 kg.

② Open field seedling: spring sowing in March, autumn sowing in September ~ October, before sowing, first irrigate the ridge surface with water, after water infiltration dry, ditch, seed germination evenly sowed into the ditch, covered with fine soil mixed with soil fertilizer, slightly suppressed, covered with grass moisture preservation, seed amount per mu 8~10 kg.

3. Warming seedlings: Warming seedlings can sow early and emerge early. First, sow the seeds stored in the sand mixture into the seedbed and cover them with a layer of thin soil. Spray warm water once a day in the morning and evening. The seedlings can emerge in about 1 week. Strengthen fertilizer and water management after emergence. They can be planted in the middle and late March.

The cultivation method of Belamcanda chinensis

1. Soil preparation: apply manure 20000 kg/ha to the planting plot of Belamcanda chinensis, till 20 cm, apply potassium sulfate compound fertilizer and ammonium dihydrogen phosphate 750 kg/ha respectively at the bottom of the ditch, rake and level the furrow, irrigate the furrow first when the land is dry, and then sow when the topsoil is loose.

2. Reasonable rotation: Belamcanda chinensis can adopt the method of water-drought rotation in the farmland where weeds seriously occur in dry fields such as crabgrass, purslane and field convolvulus, so that the above weeds cannot survive, and the underground stems of some perennial weeds can be drowned.

3. Loosening and watering: keep the ridge surface wet before emergence of Belamcanda chinensis in spring, loosen soil and weed in time after emergence, water and loosen soil in time after emergence, keep the soil surface loose, moist and free of weeds, pull grass only after planting and sealing in June, and cultivate soil in time at the root to prevent lodging.

4, timely weeding: after planting Belamcanda generally four times in the first year, the first time in the emergence, after May, July, November each time. The following year and later, it will only be conducted once in March, June and November respectively.

5, reasonable topdressing: Belamcanda in the early and middle growth of fertilizer, fertilizer control later, more fertilizer or compost, 37500~60000 kg per hectare plus calcium superphosphate 225~375 kg, topdressing should be 3 times a year, respectively in March, June and winter.

6. Bolting and topping: Belamcanda chinensis blooms in early July, and bolting and flowering consume a lot of nutrients. Therefore, in addition to planting, other plants must be plucked in time when bolting, so that their nutrients are concentrated for rhizome growth, so as to increase yield.

7. Harvesting and processing: Belamcanda chinensis seeds can be harvested after 3 years of reproduction. Harvest when the stems and leaves of the plants wither in late November. Dig out the rhizomes, remove the stems and leaves and soil, dry them to half dry and rub the fibrous roots, and then dry them completely. It is better to have thick and large rhizomes, yellow colors, no soil and no roots.

Pest Control of Belamcanda chinensis

1. Belamcanda rust

[Harm] Autumn damage plant leaves, brown raised rust spots, rust powder after rupture, early adult plants, seedlings occur late.

[Control] Spray 95% sodium rust 400 times solution at the beginning of the disease, once every 7~10 days, and spray 2~3 times continuously.

2. Root rot of Belamcanda chinensis

[Harm] Belamcanda root rot occurs frequently in rainy seasons in spring and summer, and is induced by using germ-bearing seedlings or insufficiently decomposed farm manure.

[Prevention and control] After finding diseased plants, spray the plants with Bordeaux mixture of 1:1:120 in time. Seriously diseased plants should be uprooted with soil and burned outside the field. The roots of diseased plants should be disinfected with lime.

3. Borer

[Hazard] Borer is the main pest of medicinal plants such as Belamcanda chinensis. The adult is about 20 mm long, with yellow brown head and white long hair.

[Control] Spray 50% carbaryl powder during the incubation period of overwintering eggs, 1.5~2.5 kg per mu, and spray 90% trichlorfon 800 times solution when larvae harm leaf sheaths in early May.

4. White grubs

[Harm] White grubs mainly bite rhizomes and tender stems, causing serious damage. During the day, they can be found in the rhizosphere of damaged plants or 3~6 cm below the soil nearby.

[Control] The manure applied should be fully decomposed, preferably high temperature compost. It can be trapped in the field with black light or electric lamp. Put the insect container under the lamp, and add a little kerosene to the small amount of water.

5. Ground tiger

[Harm] The ground tiger is also called cutting insects, ground silkworms, etc. The larvae harm the stems of Belamcanda chinensis on the ground, often biting off the stems from the ground to cause the plants to die, resulting in lack of seedlings and broken strips.

[Control] Pest serious plots can be irrigated with 700 times solution of 59% phoxim emulsifiable concentrate or 800~1000 times solution of 80% wettable trichlorfon powder, and the effect is better.
