Cultivation Methods of Several Chinese Herbal Medicine

Dry Pinellia ternata

Land preparation is cold-resistant to drought and Pinellia ternata, and loose and fertile sandy or semi-sandy soil is the best, as well as general soil. Before ploughing, 100 mu of phosphorus and potash fertilizer was applied to 150 kg, and deep ploughing and fine harrowing was made to move from east to west to the border.

The sowing method is propagated with tubers, ditching with gouges according to row spacing of 21cm to 24cm, ditch depth of 4cm to 6cm, sowing bulbs according to plant spacing of 5cm to 7cm, then cover the soil flat and push it twice with a big hoe. If the land is moist, do not water, wait for the seedlings to grow, look at the soil moisture appropriate watering.

Field management, 1.5 cm apart in the border, planted a row of high straw crops in the east-west direction, such as corn (1720, 18.00, 1.06%) or sorghum, which is beneficial to the growth of Pinellia ternata. The seedlings of Pinellia ternata should be poured 2 or 3 times a year, and each time the seedlings can be watered, which is beneficial to seedling emergence and re-growth. Pay attention to watering during drought and drainage when it rains.

Harvest and processing according to different conditions, before and after Frost fall Festival or spring harvest planing in the following year. Dig out the bulbs, the large ones are processed into medicine, and the small ones are used for seed. Put the medicine into a sack, put it on the board or slate, rub it with water while rubbing, peel off, then pour it into a sieve and immerse it in water, bleach the residue, dry it and sell it.

Radix Astragali

The adaptability of Astragalus membranaceus is very strong, the general soil can be planted, drought-resistant, cold-resistant, with deep, loose and fertile soil.

The planting method can be sowed in spring, summer and autumn. Soak the seeds in warm water before sowing, fish out the seeds and put them in a basin after 6 hours, and then sow. Select sandy soil with good drainage and strong water permeability, apply sufficient bottom fertilizer and plough fine rake to make a wide border. After watering for 3 to 5 days, flatten the border surface with iron rake, open a ditch 1 to 2 centimeters deep according to the row spacing of 23 centimeters, sow the seeds into the ditch and push them with a big hoe. Then the border surface will be flat and thin, and the seedlings will emerge in 6-7 days.

The field management kept the soil moist before emergence, watered less and loosened the soil after emergence, and the seedling height was 6-7 cm according to the distance of 10-13 cm. It is 1720cm high for topdressing, 10kg for chemical fertilizer per mu and 25kg for fermented cake fertilizer. When it is about to blossom, the water demand will gradually increase, so the watering times can be increased appropriately. There are generally no diseases and insect pests, such as too much Rain Water, you can pay attention to drainage.

Harvest and processing after the autumn of the current year or the next autumn, the aboveground stems and leaves withered and harvested. Mix the soil, remove the Reed stems, dry them, tie them into small handfuls and sell them.

Radix Isatidis

The growth habit is not strict to the soil, and the soil can be planted in cold and warm areas. Afraid of waterlogging, like the sun, can be continuous cropping.

Cultivation management uses seed propagation, spring sowing and summer sowing. Spring sowing: from March to May, choose good drainage, loose and fertile soil, according to the row spacing of 18-20 cm, draw a ditch 15 cm deep. Spread the seeds evenly into the ditch, cover the soil, step on the foot once, or push it twice with a big hoe and water it flat. It usually takes about 18 ℃ and emerges in 7-10 days. Summer sowing: from June to July, the method is the same as spring sowing, and seedlings emerge in 4-5 days.

The height of the field management seedling is about 6 cm, and the plant distance is about 5 cm. From Lesser Fullness of Grain to Mangzijie, 15 kg of ammonium nitrate and 15 kg of superphosphate can be applied per mu, watering after burying the soil, the Summer Solstice cutting leaves in the summer festival, and 10 kg urea when watered 4-5 days after leaf cutting.

Harvest and process spring sowing Radix Isatidis to cut the leaves once in the summer, cut off the leaves from the base and dry them in the sun for a day or two. Cold Dew to Frosts Descent planed the roots, dried them and used them as medicine. If sown in summer, the leaves will be cut and dried when planing, and the root planing season will be the same as above.

Honeysuckle

Honeysuckle is a perennial shrub of honeysuckle family. It can grow all over the country and is unharmed at minus 35-40 ℃.

The characteristic stem of the plant is erect, with a height of 1 m to 1.5 m in the same year after planting. If it is found to be overgrown, it should be cut off to facilitate more lateral branches. The more lateral branches, the higher the yield. 500 plants were planted per mu, and the survival rate was more than 98%.

The flower buds were picked once in the first half of the year, once before and after the Mid-Autumn Festival, and dried in a ventilated and dry place after harvest. After planting, the flower was in full bloom in the second year, and maintained for many years, yielding 100kg dry flowers per mu. Winter planting before freezing, spring planting flowering to 6.1 node, according to row spacing 1.5 meters, plant spacing 1.2 meters, digging small holes for cultivation. You can survive by pouring some water. Hillsides, wasteland and sandy beaches can grow.

Field management at the end of autumn every year, remove the dead branches and leaves at the base of the flower stump and peel off the cork of the branches and stems, which can reduce the harm of diseases and insect pests in the coming year. The 30 cm soil around the flower pier is turned deep, and 5kg of soil fertilizer is applied to each pier, and 0.1 kg of calcium superphosphate is applied conditionally, which is formed into a groove shape which is high all around and low in the middle. After fertilizing the flower pier in the mountain, the flower pier will be shaped into a fish phosphorus pit or basin according to the topography to facilitate the accumulation of rain and snow. After picking the first stubble flowers, quick-acting fertilizer should be applied in time to increase the yield of the second and third stubble flowers.

Winter shearing is generally carried out after all the leaves fall off in winter to before sprouting in the following spring. Winter shearing mainly grasps the principle of "strong branches are cut lightly, weak branches, heavy branches, and branches are all cut"; strong branches should be lightly cut and generally retain 8-10 buds; weak branches should be heavier and 3-5 pairs of buds should be retained; thin, weak, diseased and winding branches should be completely cut off. The shearing of plants with good water and fertilizer conditions and strong growth should be retracted and renewed, mainly by thinning and deletion, and by the method of "major operation" to transform and renew the old flower stump. For the young flower plants after planting, it is mainly to cultivate the plant type, generally leaving 3 to 5 main poles first, and the layout of the main rod should be reasonable, and the top tip should be cut short to promote its thickening.

Summer shearing has a great effect on the yield increase of the second and third stubble flowers, the yield is significantly increased when properly pruned, and the flower picking time is relatively concentrated, which is convenient for picking. Generally, after picking the flowers in the previous stubble, the top tip of the vigorous branches should be cut off to control the top dominance to facilitate the germination of new branches; for the twigs with weak growth and yellowing leaves, all the twigs that affect ventilation and light should be cut off.

It can be picked 15-20 days after harvest and processing. The upper part of the bud is enlarged and bluish white is the suitable time for picking, and the delay will lead to the opening of flowers, affecting the quality and yield of goods. Picking should be in the early morning and morning every day, and the postharvest flowers should be processed and dried in time.
