Breeding methods of Anemarrhena anemarrhena

Anemarrhena anemarrhena, also known as Anemarrhena anemarrhena, is a perennial herb of the genus Anemarrhena in Liliaceae. it can be sowed in all seasons throughout the year, mainly in spring or summer. In recent years, in order to shorten the growth cycle, many places have also adopted the method of ramet breeding. Let's take a look at Anemarrhena anemarrhena's breeding method.

The growth habits of Anemarrhena asphodeloides

Anemarrhena anemarrhena is a perennial herb with warm climate, cold and drought tolerance, and sandy loam with loose, fertile and well-drained soil is better. It is not suitable to plant in shady slope and low-lying land. It germinates when the average daily temperature is more than 10 ℃ in spring, the period of vigorous growth is from April to June, the expansion and filling period of underground rhizome is from August to September, the plant withered in November and the growth period is 230 days.

Ramet propagation of Anemarrhena anemarrhena

The ramet propagation of Anemarrhena anemarrhena should be carried out before sprouting in early spring or after the plant enters the dormant period in late autumn. the 2-year-old rhizome is dug out, cut into segments with whisker roots, 2-3 buds in each section, planted in a trench with a plant spacing of 5 cm × 20 cm, and the ditch depth is 1-5 cm. The cut propagation materials are laid flat in the ditch, covered with soil, pressed and watered. When planting in late autumn, in order to survive the winter safely, the soil above each plant is 6 cm-7 cm thick, and the soil pile is leveled the following spring to facilitate the unearthed growth of new buds. In order to save breeding materials, it can also be combined with harvest to cut off the bud head of the planed rhizome as propagation material, to propagate separately, and its rhizome is processed for human medicine.

Seed propagation of Anemarrhena anemarrhena

1. Seed collection and storage: after sowing, Anemarrhena anemarrhena began to produce flower stems in the second year, only 1 flower stem in 2-year-old plants and 5-6 flowers in 3-year-old plants. The number of flowers on each stem was about 150-180, and the fruit matured about 60 days after flowering. For seed collection, robust plants without diseases and insect pests should be selected for seed collection. The fruit ripening period is from mid-August to mid-September, and the fruit is easy to fall off. Therefore, when the fruit is just ripe, it should be picked in sequence, rub out the seeds after harvest, winnow the impurities and store them for use.

2. Seed selection: the experiment shows that the germination rate of Anemarrhena anemarrhena seeds is not high, and the germination rate of the seeds collected in the previous year is 40% 50%, so the seeds with storage time of less than 2 years should be selected for sowing.

3. Soak and promote germination: soak the seeds in the first and middle of March, soak the seeds in 60 ℃ warm water for 8-12 hours, remove and dry the outer skin, mix well with twice the moist fine sand, dig a shallow pond in the sunny warm place, pile the seeds in the pond, cover the soil 5cm-6cm thick, and then cover them with agricultural film. The seeds are compacted with soil around, and the temperature suitable for germination is higher. The time of germination is related to the temperature at that time. The average temperature begins to germinate at 13 ℃-15 ℃, about 25-30 days. When the temperature is 18 ℃-20 ℃, it germinates in 14-16 days. When the germ of most seeds just protrudes the seed coat, it can be sown into the field, and the sowing amount per mu is about 3 kg.

4. Sowing time: Anemarrhena anemarrhena can be sowed in autumn or spring, autumn sowing before freezing, spring sowing in April.

5. Sowing method: in the pre-arranged border surface, the furrow spacing is 20 cm, and the ditch depth is 2 cm. The budding seeds are mixed with ammonium sulfate at the proportion of 1:5, then sprinkle evenly into the ditch, cover the soil flat, slightly suppress, and keep the soil moist. As long as the soil moisture is good and the temperature is normal, seedlings can emerge in about 10-20 days.
