How does traditional Chinese medicine calamus grow with soil? Can I get hydroponic culture? What if the leaves turn yellow?

Calamus is also called white calamus, Tibetan calamus. Born near marshes, streams, or paddy fields. Chinese traditional culture can be used to ward off disease spirit grass, Dragon Boat Festival has the calamus leaves and moxa bundle inserted under the eaves of the custom. Therefore, more and more people began to plant calamus, so how to cultivate calamus with soil? Can you grow water? What if the leaves turn yellow?

1. How to cultivate calamus?

1. Reproductive methods

Usually when breeding calamus, we must understand its reproduction mode, it can be reproduced by means of bead division, this reproduction mode should be carried out in September to October every year, reproduction, you can take out the big spider, remove the withered old leaves, and then divide the plant into multiple, piglets can be planted in the flowerpot watering enough water.

2. Soil

Acorus calamus is a kind of hygrophilous plant growing at the water's edge. When planting at home, we must choose the culture soil with good drainage, and keep the pot soil moist. In addition, the vitality of Acorus calamus is particularly strong, and it grows very fast. During the cultivation period, it is necessary to change the pot in time. It is most appropriate to change the pot once a year. The time of changing the pot should be in the spring of each year.

3. Fertilization method

Acorus calamus L. has strong adaptability in growing season and can be managed extensively. Acorus calamus likes nitrogen fertilizer, decomposed bean cake water fertilization is the best, can avoid burning seedlings, nitrogen fertilizer can promote its growth, late need to apply topdressing 2-3 times, and combined with fertilization weeding. Nitrogen fertilizer should be used mainly in the early growth stage of calamus, phosphorus fertilizer and potassium fertilizer should be applied before heading and flowering to enhance the immunity of calamus. Pay attention to each fertilizer must be buried in the soil surface about 5 cm, pay attention not to be too close to the roots, avoid burning roots. Before overwintering, we should clean up the dead branches and leaves on the ground, and clear the pathogens of diseases and insect pests.

4. Reproductive methods

sowing

The collected ripe red berries are cleaned, sown indoors in autumn, kept in moist soil or shallow water, germinated one after another in early spring at about 20 DEG C, and then cultured separately. When the seedlings grow strong, they can be transplanted and planted.

Ramet

In early spring (around Qingming) or during the growth period, dig out the underground stem with a shovel, wash it clean, remove the old roots, stems and dead leaves, stems, and then cut the underground stem into several pieces with a sharp knife. Each piece retains 3-4 new buds for reproduction. In the growth period for sub-planting, the plant roots will be dug up, washed, remove 2/3 of the roots, and then divided into blocks, in the sub-plant to maintain good tender leaves and buds, new roots.

2. Can the calamus be cultured?

Acorus calamus is a plant that likes shade and humidity in nature. From this point of view, water cultivation is better than mud cultivation. Indoor viewing is mainly based on hydroponic cultivation. As long as the water is not dried up, the life span can reach decades.

hydroponic method

Acorus calamus with large old roots is suitable as the target material for hydroponic cultivation. It is better to have the old roots higher than the mud surface and meander like a dragon walker. It is OK to group the scattered small plants into a group, wrap them with palm skin and place them in a basin. However, the roots of small plants are very short. You can string these calamus into a group with enameled wire. It is necessary to pay attention to not damaging the old roots, and then surround them with enameled wire for several circles.

Cultivation can be based on personal preferences, plant size, choose a medium depth of watertight flower, will clean the calamus stem section, trim off the old roots and long roots, first soak in potassium permanganate solution for 2 hours sterilization disinfection, will be filled with pebbles while fixing the plant in the pot, horizontal surface can touch the roots, do not soak the leaves, and finally placed in a place with sufficient light on it, do not make sunlight exposure.

3. What should I do if the calamus leaves are yellow?

1. Yellow water

Water yellow calamus likes water, generally watering does not affect the growth of calamus, but if the cattail basin used has no bottom hole, or the plant material is impermeable, the ponding in the basin becomes waterlogging, causing soil hypoxia, the cattail root rot, cattail leaf yellow. In addition, the southern days back to the south, plum rain days should also pay attention to this kind of weather rainy continuous, air humidity is extremely high, transpiration reduced, calamus also easy to appear yellow leaves. In case of yellow water, first of all, reduce the watering frequency and watering amount, place the calamus in a ventilated place, and replace it as soon as possible if it is a cattail pot or planting material problem.

2, drought yellow

Generally, we raise calamus for beauty, more small pots, small space and less plant material, if the weather is sunny and hot, two or three days without watering will appear drought problem, for calamus, this is to be close to life, immediately yellow face to you to see. Drought yellow first to water as soon as possible, but at this time the physiological function of calamus has not recovered, not easy to irrigate more, keep the soil moist can, let calamus gradually adapt.

3, dry yellow

Different from drought yellow, dry yellow is caused by too little air humidity, which is easy to occur indoors in midsummer or in the north with heating. Due to the low air humidity, transpiration is strong, acorus is easy to yellow leaves scorched tip. Dry yellow first to increase the amount of watering, and then you can consider making a basin or sand basin, put a brick at the bottom of the basin, water should not be over the brick, calamus basin on the brick, artificially create a small environment, increase air humidity, sand basin similar. If it is summer, pay attention to shade, or put calamus in a cool and ventilated place.

4, burning yellow

Acorus calamus is a shade-loving plant, generally placed in a place with scattered light, winter and spring season can be properly exposed to the sun, but if it encounters strong direct sunlight, the acorus will appear yellow leaf coke tip, at this time pay attention to put back to a cool and ventilated place.

5, alkali yellow

Acorus calamus likes weak acid growth environment, if the water quality is alkaline, or long-term sitting basin, salt accumulation in the basin soil, then the cattail leaves naturally turn from green to yellow, usually try to use clean water, do not sit basin for a long time. If alkali return serious, can be neutralized with ferrous sulfate solution, but considering the actual situation, I think it is better to change the soil directly on the basin to save trouble.

6, frozen yellow

Acorus calamus likes to grow in an environment of 15-25 degrees Celsius. It grows slowly below 10 degrees Celsius. It should be taken back indoors or added warm facilities below 5 degrees Celsius. Some people say that zero or even zero may not be dangerous, but why take that risk? For example, last winter, many people's calamus were frozen. If there is frozen yellow, the yellow leaves should be removed as soon as possible and placed in a warm environment to regenerate the roots and leaves.

Calamus leaves appear yellow, even withered phenomenon, we first have to find its cause. Once the cause is found, it should be timely prescribed medicine, in order to change the leaves of calamus from yellow to green as soon as possible. Moreover, the reasons for the yellowing of calamus leaves are not only the same, so we must take it seriously and investigate it carefully in order to solve this problem perfectly.

The above is to sort out some of the breeding index points for everyone, I hope to help you.
