The main points of the latest course on planting techniques and methods of Tiannanxing

Rhizoma Arisaematis is a traditional Chinese medicine with a long history of cultivation in China. It has the effects of detoxification, detumescence, phlegm and dispelling wind. It is often used to treat nerve paralysis, hemiplegia, infantile convulsion, tetanus and other diseases. Moreover, the scope of cultivation of Arisaema in China is also very wandering, basically dealing with northwest and Xizang areas, lower than all over the country. So how do you cultivate high-yield, high-quality Arisaema? Let's take a look at the technical points of Arisaema cultivation brought to you by Xiaobian.

1. Seed treatment

The seed treatment of Rhizoma Arisaematis plays a very important role in its planting process, which basically determines the survival rate, yield and quality of Rhizoma Arisaematis planting. So first we need to divide the seed stem of Arisaema into three levels: large, medium and small; then use methyl thiophane mixed with appropriate amount of carbendazim and abamectin to soak seeds. The soaking time needs to be determined according to the size of the seed stem, which is 24 hours, 12 hours and 12 hours respectively. Finally, take out the soaked seed stems, store them in a ventilated and cool place, keep the temperature at five to seven degrees, turn them over every half month, and wait until early spring to sow.

2, planting time

Arisaema can be sown in early spring, but if the winter temperature is not lower than minus three degrees, it can also be sown. Sowing time is generally late autumn November to December, but it is best to sow in spring. Generally, when the low temperature reaches eight degrees or more, it can be sown in spring.

3. Cultivation methods

Arisaema planting methods have seed reproduction and seed stem reproduction, but the seed growth period is very long, and the yield is not high, so the most commonly used or seed stem reproduction. Before planting, it is necessary to select soil suitable for planting in the south, and carry out soil preparation and apply sufficient base fertilizer; secondly, soil treatment and disinfection; finally, sowing. When sowing, the seed stems of different levels should be planted separately. The large seeds are generally planted at intervals of 25 rows and 15 centimeters between plants; the row spacing of the medium seeds is generally 20 centimeters and the plant spacing is 10 centimeters; the row spacing of the small seeds is consistent with that of the medium seeds, but the plant spacing is generally 5 centimeters.

4. Field management

Field management is the most important in the cultivation technology of Rhizoma Arisaema. In the early stage of emergence and after emergence, appropriate watering, and weeding. When it is in the middle and late stages of growth, it is necessary to appropriately reduce the humidity of the soil to avoid plant decay. Second, it is best to carry out interplanting, so that appropriate shade management can be carried out. Of course, if the temperature is high, physical cooling is also needed. When the seedlings grow to about 18 cm, the first topdressing is carried out, and the manure and urine water are used for irrigation; the second topdressing is the middle stage of the growth of Arisaema, and the phosphorus and potassium fertilizer are used for loosening the soil. Finally, when the spathe grows out, it should be removed in time, so that several nutrients can be used to promote the growth of tubers.

The most important thing in the cultivation technology of Arisaema is to understand the growth habits of Arisaema, followed by mastering the cultivation technology and reasonably using the professional knowledge to achieve maximum economic benefits. The above is the planting technical points of Arisaema that Xiaobian wants to share with you today. I hope it can help you plant friends.
