Propagation and Cultivation Management of Asarum

Propagate with seeds and ramets.

1. Select the sandy loam with deep soil layer, rich humus and good drainage. It is best to choose under the sparse forest within the 30 °slope. Applying 2500-5000kg farm manure as base fertilizer, ploughing 25-30cm in the autumn of the first year, then ploughing in spring, leveling and fine, making a high border with a width of 1.2m 2.

2. Seed propagation

The main results are as follows: (1) the fruit of seed collection changes from purplish red to pink white, and the pulp is soft and mature. Pick as you ripen, rub the pericarp in clean water after harvest, remove the seeds, and sow them a little dry. The seed was sown immediately after seed collection, and the germination rate was 80%. After ripening treatment, the seed was sown, and the germination rate was 95%.

(2) seed storage seeds have the habit of Hypocotyl dormancy, which needs to go through embryo morphological development and low temperature to break Hypocotyl dormancy before germination. If the seeds cannot be sowed in time after harvest, the fresh seeds should be buried with 3-5 times of clean wet river sand, checked every 10 days, and the seeds should be stirred up and down for 40-50 days, not later than the end of July, that is, the seeds should be taken out for sowing. If the seeds are stored in a dry environment after harvest, the vitality will gradually decrease after 5 days, and the germination rate will be lost after 60 days of dry storage.

(3) sowing and transplanting sowing, strip sowing and hole sowing can be used. Sow the seeds with 10 times fine sand and sprinkle them on the border. The strip was sown on the border, the row spacing was 10cm, and the radiation was 4cm. Acupoint sowing line distance 13cm, acupoint spacing 7cm, each acupoint sowing 7-10 tablets. After sowing, it is covered with fine soil, and then covered with grass to keep the soil moist.

After sowing, Asarum can be transplanted after 2-3 years of cultivation. The buds were not germinated or unearthed in early spring, and the row spacing was 20cm and the plant spacing was 7-10cm. Asarum can be directly grown in situ for 3-4 years before harvesting products. The use of seed direct seeding has many advantages, which can increase the yield and reduce the occurrence of sclerotia industrial disease. At the same time, without transplanting, it not only occupies less land, but also saves manpower and material resources, reduces costs and increases benefits.

3. Ramet propagation after ripening in June, the root of the mother plant was dug out and ramet was carried out. Each plant must have 1-2 buds with fibrous roots. According to row spacing 15-20cm, plant spacing 10cm planting, compaction after covering soil, watering.

Cultivation management:

1. Asarum seedlings are small, grow slowly and are easy to suffer from early famine. Always keep the border surface free of grass, loosen the soil easily, and loosen the soil after rain or watering to prevent soil consolidation.

2. Topdressing Asarum is a fertilizer-loving plant, which is planted in barren soil and grows very slowly without fertilization. When watering in May and July every year, ammonium sulfate or calcium superphosphate was dissolved in water and applied to the border mainly by compost or barnyard manure after autumn.

3. Planting in the shaded field needs a shed for shading, and the height of the shed is about 1cm. There is no shade and full light in early spring. Starting from the beginning of June, the shade is covered with straw or straw curtains, generally requiring a shade degree of 50% Mel 60%, and the curtain length and width is limited to crossing the border surface 30cm.

4. in late October every year, after the local upper part withered, the fermented fertilizer and about 5 times of humus soil were mixed and spread on the border to fertilize and supplement the soil washed down by Rain Water to prevent Asarum root from being exposed. it can also protect the bud safely through the winter.
