How many kinds of medicinal materials are harvested once a year?

The medicinal materials collected once a year include Gastrodia elata, Pinellia ternata, Radix Angelicae Dahuricae, Radix Saposhnikoviae, Ranunculus ternatus, Radix Isatidis and other varieties. 1, Gastrodia elata: The planting time is generally from June 1 1 to June 1 of the following year, and it is suitable for planting in February-April in spring. The yield per mu of conventional planting is generally about 400-500 kg. 2. Pinellia ternata: It should be planted in February-March in the south of the Yangtze River and April-May in the north. The yield per mu of conventional planting is generally around 150-200 kg.

First, Gastrodia elata

1, the planting time of Gastrodia elata in winter is generally 1 1 to the following year 1, the planting time in spring is generally from February to April, and the annual harvesting time is generally10-12 (the growth will stop in September). Harvesting and processing before it snows in winter can improve the quality of gastrodia elata.

2. If the gastrodia elata is harvested too early, the gastrodia elata is immature, and the yield after harvesting is low, and the quality will also be affected; If the harvest is too late, it will be vulnerable to freezing injury and underground pests and rodents.

3. Under the condition of conventional planting, the output of gastrodia elata is generally about 400-500 kg/mu.

Second, Pinellia ternata

1. This medicinal material is widely distributed in the Yangtze River Basin, Northeast China and North China, and also distributed in Tibet, generally growing below 2500 meters above sea level.

The planting season of this medicinal material needs to be decided according to the local climate. Generally, it is suitable for planting in February-March in the south of the Yangtze River and April-May in the north.

3. The harvesting period is usually in summer or autumn, and can be excavated after the stems and leaves wither and drop seedlings (the harvesting period is between the awn seeds and the summer solstice). In the case of conventional planting, the output of dry goods is generally around 150-200 kg/mu.

Third, angelica dahurica

1. This medicinal material can be sown in spring or autumn, but autumn sowing is suitable, in which the autumn sowing time is around the Millennium in Henan, from the Millennium to the autumnal equinox in Sichuan, from the summer to the Millennium in Hebei, and before the cold dew in Zhejiang 10 day.

2. In the area with high temperature, it is suitable to sow from autumnal equinox to cold dew. If the seeds are sown too early, the plants will easily grow too vigorously in the same year, and some plants will germinate in advance in the second year, resulting in lignification of the roots and loss of medicinal value; If sowing is too late, it will be difficult to germinate because of less precipitation and low temperature after winter.

From March to July, seeds can mature one after another. When the peels turn yellow-green (yellow-white in Henan), they will be harvested together with the fruit sequence. In the case of conventional planting, the yield is generally around 500-600 kg/mu.

Fourth, wind protection.

1. This medicinal material can be planted in spring or autumn. If it is sown in spring, the sowing time in North China is the first half of April, and the sowing time in the Yangtze River basin is from late March to mid-April. For example, sowing in autumn can be done before freezing in North China (seedlings can emerge in the following spring) and in the Yangtze River basin in September-65438+10.

2. After sowing, it can generally be harvested at the end of June, 65438+ 10 to mid-June 165438+ 10 (or before spring germination), and management should be strengthened in the later stage of planting. The output of conventional dry goods is generally around 150-300 kg/mu.

Five, Ranunculus ternatus

1, and the planting time is generally March-June+065438+1October, so we should choose fertile and loose moist soil for planting, and harvest the fruits when they are ripe (generally May-June).

2. Dry the fruit in the sun, thresh it, and then screen out the seeds, which can be used for sowing, but usually it will not emerge until September, and the finished product will not be harvested until May of the following year.

3. In conventional planting, the yield per mu is generally around120-150kg/mu.

Six, Banlangen

1. After planting, it can be harvested in June10-1(after the overground part withers). When harvesting, dig a deep ditch about 50 cm deep from one side of the planting bed, and then dig forward in sequence until the roots are dug out.

2. After digging the roots, shake the soil, then wash it and dry it for a while, then tie it into small bundles and dry it thoroughly.

3. Under conventional planting, the yield of dry roots is generally about 600 kg/mu, and it can reach 800- 1000 kg/mu at high yield.
