Detailed Explanation of Jack-in-the-pulpit (Arisaema) Planting Techniques and Management Methods
Jack-in-the-pulpit (Arisaema) is a traditional Chinese medicinal herb with a long history of cultivation in China. It has effects such as detoxification and reducing swelling, resolving phlegm and dispelling wind, and is commonly used to treat diseases such as nerve paralysis, hemiplegia, infantile convulsions, and tetanus. Moreover, the cultivation range of jack-in-the-pulpit in China is also very extensive; basically, except for the northwest and Tibet regions, it is cultivated in various places. So how can you cultivate high-yield and high-quality jack-in-the-pulpit? Let's take a look at the key technical points of jack-in-the-pulpit planting that the editor has brought to you below.

1. Seed treatment
Seed treatment of jack-in-the-pulpit plays a very important role in its planting process, as it basically determines the survival rate, yield, and quality of jack-in-the-pulpit cultivation. First, we need to divide the seed stems of jack-in-the-pulpit into three grades: large, medium, and small; then mix thiophanate-methyl with an appropriate amount of carbendazim and abamectin to soak the seeds. The soaking time needs to be determined according to the size of the seed stems, which are 24 hours, 12 hours, and 12 hours respectively. Finally, remove the soaked seed stems and place them in a ventilated and cool place for storage, maintaining the temperature at 5 to 7 degrees, turning them once every half month, and by early spring they can be sown.
2. Planting time
The sowing time of jack-in-the-pulpit can be in early spring, but if the winter temperature is not lower than minus 3 degrees, it can also be sown. The sowing time is generally from November to December in late autumn, but spring sowing of jack-in-the-pulpit is still the best. Generally, when the low temperature reaches above 8 degrees, spring sowing can be carried out.
3. Planting methods
The planting methods of jack-in-the-pulpit include seed propagation and seed stem propagation, but the growth period of seeds is very long, and the yield is not high, so seed stem propagation is most commonly used. Before planting, it is necessary to select soil suitable for jack-in-the-pulpit cultivation, carry out land preparation, and apply sufficient base fertilizer; secondly, carry out soil treatment and disinfection; finally, sow. When sowing, seed stems of different grades should be planted separately. Large seeds are generally planted at a spacing of 25 cm between rows and 15 cm between plants; medium seeds are generally planted at a row spacing of 20 cm and a plant spacing of 10 cm; the row spacing of small seeds is the same as that of medium seeds, but the plant spacing is generally 5 cm.
4. Field management
Field management is the most important part of jack-in-the-pulpit planting techniques. In the early stage before emergence and after emergence, water appropriately, and carry out hilling and weeding. In the middle and late stages of growth, appropriately reduce soil moisture to prevent plant rot. Secondly, it is best to carry out intercropping, so that appropriate shading management can be carried out. Of course, if the temperature is relatively high, physical cooling is also needed. When the seedlings grow to about 18 cm, carry out the first topdressing, irrigating with manure and urine water; the second topdressing is in the middle stage of jack-in-the-pulpit growth, applying phosphorus and potassium fertilizer by loosening the soil and trench application. Finally, when the spathe grows out, remove it in time, so that nutrients can be concentrated and the growth of tubers can be promoted.
The most important thing in jack-in-the-pulpit planting techniques is to understand the growth habits of jack-in-the-pulpit. Secondly, it is necessary to master the planting techniques well and reasonably apply the professional knowledge acquired to achieve maximum economic benefits. The above are the key technical points of jack-in-the-pulpit planting that the editor wants to share with you today, hoping to help all planting friends.
