How to Grow Arisaema? Key Points of the Latest Cultivation Techniques and Methods Tutorial
Arisaema is a Chinese medicinal herb with a long history of cultivation in China, possessing effects such as detoxification and swelling reduction, phlegm resolution and wind dispelling, and is commonly used to treat neuritis, hemiplegia, infantile convulsions, tetanus and other diseases. Moreover, the cultivation range of Arisaema in China is also very wide; basically, except for the northwest and the Xizang region, it is grown in various places. So how can you cultivate high-yield, high-quality Arisaema? Let's take a look below at the key technical points of Arisaema cultivation that the editor has brought to you.
1. Seed treatment
Seed treatment of Arisaema plays a very important role in its cultivation process; it basically determines the survival rate, yield and quality of Arisaema cultivation. First, we need to divide the seed corms of Arisaema into three grades: large, medium and small; then use thiophanate-methyl mixed 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 corms, namely 24 hours, 12 hours and 12 hours. Finally, remove the soaked seed corms and place them in a ventilated and shaded place for storage, keeping the temperature at 5 to 7 degrees, turning them once every half month, and by early spring they can be sown.
2. Planting time
Arisaema can be sown in early spring, but if the winter temperature is not lower than minus 3 degrees, sowing is also possible. The sowing time is generally from November to December in late autumn, but among these, spring sowing of Arisaema 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 Arisaema include seed propagation and seed corm propagation, but the seed growing period is very long, and the yield is not high, so seed corm propagation is still the most commonly used. Before planting, it is necessary to choose soil suitable for Arisaema cultivation, carry out land preparation and apply sufficient basal fertilizer; next is soil treatment and disinfection; finally, sow. When sowing, seed corms of different grades should be planted separately. Large seeds are generally planted at a row spacing of 25 and a plant spacing of 15 cm; the row spacing for medium seeds is generally 20 and the plant spacing is 10 cm; the row spacing for small seeds is the same as that for medium seeds, but the plant spacing is generally 5 cm.
4. Field management
Field management is the most important part of Arisaema cultivation techniques. In the early stage before emergence and after emergence, water appropriately and carry out hilling and weeding. By the middle and late stages of growth, the soil humidity needs to be appropriately reduced to prevent the plants from rotting. Next, it is best to carry out intercropping, so that appropriate shading management can be provided; 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, watering with manure and urine water; the second topdressing is in the middle growth stage of Arisaema, 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 the tuber can be promoted.
The most important thing in Arisaema cultivation techniques is to understand the growth habits of Arisaema; next is to master the cultivation techniques well and reasonably apply the professional knowledge you have mastered to achieve the greatest economic benefit. The above are the key points of Arisaema cultivation techniques that the editor wants to share with you today, hoping to help all friends who grow it.
