The latest propagation method of shoot stem

Belamcanda chinensis is usually propagated by seeds and rhizomes. The production cycle of seed reproduction is long, but the reproduction coefficient is high. The harvest of rhizome reproduction is early and effective, but the reproduction coefficient is low. Long-term planting will also lead to germplasm degradation. Therefore, it is advisable to use two methods alternately in production. Let's take a look at the propagation methods of Belamcanda chinensis together.

Growth Habits of Belamcanda chinensis

Belamcanda chinensis likes warm and sunshine, drought and cold resistance, and is not strict with soil requirements. It can be cultivated in hillside dry land. It is better to cultivate fertile and loose sandy loam with high terrain and good drainage. Neutral loam or slightly alkaline loam is suitable. Low-lying land and saline-alkali land are avoided.

Rhizome propagation of Belamcanda chinensis

1. Rhizome treatment: in late January, dig out the rhizome for seed, select the rhizome with strong growth, bright yellow and no diseases and insect pests, cut the root segment of 4 cm long according to every 2~3 buds and part of fibrous roots (properly prune the long fibrous roots for planting survival), after the incision heals, soak the seed rhizome in ABT4 rooting powder solution with concentration of 50 ppm for 3 hours and plant it, so as to promote the dormant buds on the rhizome to germinate and sprout early. The experiment proved that the seedling emergence of treated rhizomes was 10 days earlier than that of untreated rhizomes, and the seedling emergence rate of rhizomes was increased by 30%.

2. Planting method: When Belamcanda chinensis is planted, holes are dug according to the row spacing of 25 - 30cm and the plant spacing of 20 - 25cm on the arranged ridge surface, the depth of the holes is 15cm, the bottom of the holes should be flat, the subsoil should be loosened, the mixed fine soil should be applied into the opened planting holes, and then 1 - 2 sections of seed roots should be planted in each hole, and then 6 - 7cm thick fine soil should be covered, slightly compacted and watered thoroughly.(It is best to apply decomposed human and animal excrement and urine water), then cover the fine soil and the ridge surface, then cover the plastic film, about 50 days can emerge, at this time to break the film in time to release seedlings, prevent high temperature burning seedlings.

Seed propagation of Belamcanda chinensis

1. Seed collection: usually from late September to early October, when the shell turns yellow and is about to crack, the fruit stalk is cut off and dried indoors.

2. Germination treatment: Harvested seeds should not be exposed to the sun, otherwise the hardness of seed coat will be increased. Belamcanda chinensis seeds have post-ripening property and must be treated at low temperature and humidity to complete physiological post-ripening. Spring seeds must be treated at low temperature to germinate. Autumn seeds should be mixed with 3 times wet sand and buried outdoors. The size and depth of pits depend on the number of seeds. Keep wet and not be frozen. The seeds should be dug out and sown in the following spring. Autumn seeds should be soaked in warm water at 40~50℃ for 24 hours, and then dried and 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 in September ~ October, generally furrow sowing is adopted, on the well ridged surface, furrows are fixed according to the row spacing of 25 cm ×30 cm, the depth of furrows is about 5 cm, the bottom of furrows should be flat and loose, soil miscellaneous fertilizer is applied in each hole, the thin soil is about 2 cm thick, then 5~6 seeds promoted to bud are sown, the soil is covered and compacted after sowing, proper amount of watering is carried out, the grass is covered for moisture preservation, the seed quantity per mu is 2~3 kg, and the seedlings can emerge about 20 days after sowing.

② Open field seedling: spring sowing is carried out in March, autumn sowing is carried out in September ~ October, the ridge surface is irrigated thoroughly before sowing, after water infiltration is dry, the row spacing is 20 cm, the depth is 6 cm, and the sowing width is 10 cm, then the germinated seeds are evenly sown into the ditch, covered with fine soil mixed with soil and miscellaneous fertilizer with a thickness of 5 cm, or the seeds prepared in advance are sown into the seedbed, covered with fine fertilizer soil with a thickness of 5~6 cm, slightly suppressed after sowing, covered with grass for moisture preservation, and the seed amount per mu is 8~10 kg.

③ Temperature seedling: usually to make Belamcanda seeding year to extend the growth period, can use plastic small arch shed temperature, can sow early early emergence, with plastic small arch shed seedling can be carried out in January, according to the conventional operation method, first mixed sand storage crack seeds sowed into the seedbed covered with a layer of thin soil, spray warm water every morning and evening, about 1 week can emerge, strengthen fertilizer and water management after emergence, to the middle and late March can be planted in the field.
