Where is calamus grown, and what is the planting technology and cultivation area of calamus?

Acorus tatarinowii (Latin scientific name: Acorus tatarinowii) is a grass-like perennial herb belonging to the Araceae family, and its rhizomes have a scent. The leaves are entire, arranged in two rows, the fleshy spike inflorescence (Buddha flame inflorescence), the peduncle is green, and the Buddha flame bract is leafy.

Rhizomes are often used medicinally. It grows at an altitude of 20 to 2,600 meters above sea level, and is mostly found in the crevices of mountain streams or between the gravel of mountain ravines (sometimes it grows in water). The flowering and fruiting period is from February to June.

It is distributed in Asia, including northeastern India, northern Thailand, China and other countries.

Cultivation method of stone calamus:The propagation of the calamus mainly depends on the rhizome. In the spring, the rhizomes are dug out and those with fibrous roots and some leaves are selected for planting.

When planting, keep a suitable distance according to the principle of wind and light, and it is recommended to plant 2-3 rhizomes in each pit, and bury and compact the soil around the rhizomes after planting. After these tasks are completed, watering is also carried out, and generally the first watering should be sufficient.

The roots of the wild stone iris in the countryside can be sold for 18 yuan a catty, and the girl's mother digs the wild stone iris from the ditch back to the ground to plant!

Stone calamusPlanting techniques and cultivation areas: Usually in September and October, the plants are divided into 5 10 after removing the dead yellow leavesTillerssmall plants, then planted with watering. The row spacing of the plants is about 30 cm, and it can grow into a dense plant in one or two years.

It is found on the rocks of valley streams or in forest wetlands, and is common in marshes. The suitable temperature for growth is 18-25, and when it is lower than 15, the plant grows slowly. Plants stop growing when they are below 10. In winter, the south can overwinter outdoors, and the north needs to be overwintered.

Precautions for the planting of calamus.

Acorus can receive light, but does not like strong light, so it is best to place it in a position with light of medium intensity in home farming. Remember to move the position of the plant at noon when the light is too strong to prevent the leaves from being damaged and burned by too much light.

Calamus is a moisture-loving plant, of course, stone iris is not unexpected, watering is a very important part of the maintenance process, it is best to ensure that the plant potting soil is thoroughly moist throughout the year, and friends with conditions can place a shallow dish with water and stones under the pot, so as to better create a moist growth environment.

Planting soil: When planting calamus, you need to choose a deep layer of soil with a leeward and sunny layer. Rhizome propagation:

In the spring of each year, small rhizomes are dug up and buried in the soil, and 2-3 plants are planted in each hole. Thin fertilizer and frequent filial piety cover: During the growth period, it is necessary to apply well-rotted human feces or nitrogen fertilizer.

Pest control: Spray trichlorfon on calamus for control.

1. Plant the soil

When planting calamus, it is necessary to plough 20-30 cm of land, remove the stones, and then spray potassium permanganate into the soil for disinfection to reduce the probability of infection.

2. Rhizome propagation

When propagating calamus, it is necessary to dig out the small root system that grows too much from under the lush mother plant in March and April every spring, it is best to choose lateral roots with fibrous roots and leaves, and then plant them according to the row spacing of 30 cm and the plant spacing of 15 cm, and plant 2-3 rhizomes of calamus in each hole.

3. Apply thin fertilizer frequently

Acorus needs sufficient nutrients in the growth process, when cultivating calamus, it is necessary to apply decomposed human manure and nitrogen fertilizer once a month during the growth period of the plant to make its growth rate faster, and it is necessary to spray potassium dihydrogen phosphate or urea to it before harvesting.

4. Prevention and control of pests and diseases

Acorus is easy to be infected by locusts, when cultivating calamus, it is necessary to observe the growth state of the plant regularly, and the seedlings with serious disease can be pulled out in time, so as not to worsen the situation, and to spray trichlorfon every other week, spray 2-3 times in a row, so that the calamus grows healthily.

In the cultivation area, the stone iris is suitable for growing in a shady and humid environment, next to the dense forest at an altitude of 20 1600 meters; Sowing propagation, seeds can be collected from the mature mother plant, and then evenly sown to the surface of the soil, and the seedlings can be transplanted after growing to 10 cm; In the later management, when the temperature is lower than 4 in winter, a film needs to be built on the top to avoid frostbite on the leaves.

Acorus is suitable for growing in shady and humid environments, mostly under dense forests or beside wetland streams at an altitude of 20 to 1600 m. It can grow vigorously in sandy soil with deep soil layer, sufficient nutrients and strong air permeability. If the soil is too poor, it will cause the iris to grow poorly.

Acorus can be propagated by sowing seeds, fruits can be collected from the mature mother plant, after the seeds are taken out, they are evenly sown on the surface of the soil, and covered with a layer of 1 2 cm of thin soil, and a small amount of water is poured into the soil, so that the soil is in a slightly moist state, so that the seeds can germinate as soon as possible, and when the seedlings grow to 10 cm, they can be transplanted.

Acorus has strong adaptability to the environment, itself has strong cold resistance, can grow vigorously in the environment of more than 4 in winter, if the room temperature is lower than 4, it is necessary to cover a layer of film above it for warmth, in addition, it is necessary to often poke open the film to breathe, to avoid the plant growing in decline.

In order for the calamus to grow vigorously, it is also necessary to ensure that the nutrients are sufficient. Fertilization is mainly based on the application of nitrogen fertilizer, generally need to apply 2 3 times of thin nitrogen fertilizer every 1 2 months, and need to apply phosphorus fertilizer and potassium fertilizer before flowering. In addition, it is necessary to regularly remove the weeds generated in the field to avoid competing with the plants for nutrients and causing the plants to grow poorly.
