The latest course of high-yield planting techniques of Anemarrhena anemarrhena

Anemarrhena anemarrhena, also known as Anemarrhena anemarrhena, is cultivated all over the country. It has a strong ability to resist drought and cold. It is a perennial herb that can grow in arid mountains, deserts and wastelands. It is the preferred variety for greening mountain areas and wastelands. It can be sown in all seasons throughout the year, but it is mainly sown in spring or summer. Anemarrhena anemarrhena is a commonly used traditional Chinese medicine, which is widely used by the society.

Land selection and preparation

Choose humus or sandy loam with sunny, well-drained and loose soil, apply 2000,000kg of rotten barnyard manure, 4050kg of cake fertilizer and 30kg of phosphate fertilizer per mu, and spread them evenly into the ground. The cultivated land is 20 cm deep, leveled and made a bed with a width of 130 cm.

Planting method

1. Seed propagation: Anemarrhena anemarrhena seed matured one after another before and after Greater Heat. After harvest, threshing and removing impurities, store in a ventilated and dry place for backup. Seed propagation can be sowed in spring and autumn. Spring sowing in April; autumn sowing from October to November. In the finished border, cut a trench 2 cm deep according to the row spacing of 30ml / 35cm. Spread the seeds evenly into the ditch, cover the soil, hold flat, suppress slightly, and water. Keep the ground moist and emerge in about 20 days. About 1.5 kg of seeds are needed per mu. The germination rate of autumn sowing is high and the emergence of seedlings is neat.

2. Root-splitting propagation: planted in spring after thawing, before germination, and after withered and yellow stems and leaves on the ground in autumn. In the whole border, the hole is opened according to the row spacing of 30ml / 35cm, the plant spacing of 15cm / 20cm and the hole depth of 7cm. Cut off the remnant leaves and fibrous roots of the underground rhizome of Anemarrhena anemarrhena, break the rhizome with bud head into a small segment of 7cm long, put a section in each hole, and put the bud head up. Cover the soil and water. You can also pour water once before planting, and then prepare the land for border planting, but the border surface should not be too wet to prevent rotting roots. It is necessary to plant 90 kilograms of roots per mu.

Field management

After sowing, keep the soil moist and emerge in about 20 days. When the seedling height is 3 Mel 4 cm, loosen the soil and weed, and when the seedling height is 7 mi 10 cm, set the seedling distance by 15 mi 20 cm. If the climate is dry in the seedling stage, it should be watered properly. Anemarrhena anemarrhena cultivated with rhizome ramet grew slowly last year and should be watered. The growth is exuberant in the second year, so it is necessary to increase the watering times appropriately. In the year of root planting and the second year of seed direct seeding, 20 kg of calcium superphosphate and 10 kg of ammonium sulfate were applied per mu when the seedling height was 15 mi 20 cm. After trenching between rows, the fertilizer is buried in the soil after application combined with loosening the soil. If there is no need to leave seeds, the scape should be cut off in time. In the hot and rainy season, attention should be paid to eliminating stagnant water.

Pest control

Anemarrhena anemarrhena has a strong ability to resist diseases, and generally does not need to use pesticides for special control. The main pests are grubs, which harm seedlings and rhizomes. Use conventional methods to prevent and cure.

Harvesting and processing

1. Harvest

Both domestic and wild Anemarrhena anemarrhena are ploughed in spring and autumn. After thawing in spring, before sprouting, and from withered and yellow stems and leaves on the ground in autumn to before freezing. Dig out the underground roots with picks, and remove the stems, leaves, whiskers, roots and soil as fresh Anemarrhena. The fresh mother which is picked and planed at the right time in spring and autumn has high drying rate and good quality. Wild Anemarrhena anemarrhena is generally harvested in autumn. Because it is not easy to find before germination in spring, but picking and planing after germination has a certain impact on the quality of goods. For the harvest time of Anemarrhena asphodeloides, it takes 4-5 years to propagate with seeds and 4 years with rhizomes.

2. Mao Zhimu

① drying method. Put the harvested fresh Anemarrhena anemarrhena on the sunny open field or on the drying table, and beat it while piling it up, tipping over every 7 days, repeated many times until it is dried. It usually takes about 60 won for 70 days.

② drying method. Put the fresh Anemarrhena anemarrhena on the hot Kang in the drying room, turn it while baking, make it heated evenly, when it is semi-dry, take it out and put it on the drying table, pick out the ones with high humidity to continue baking, and then dry them when they are 80% or 90% dry, and select them again. In this way, it can be dried after two in and two out. Baking should not be done in haste to prevent burning.

3. Anemarrhena asphodeloides meat

The meat of Anemarrhena asphodeloides is scraped and dried while it is fresh. If there is plenty of sunshine, it will be dried for 3 days.
