Araceae breeding method

The propagation method of Aragonus is mainly based on tuber propagation, and it can also reproduce seeds.

First, tuber reproduction
After harvesting the tubers of Arisaema from September to October, they chose to grow strong, intact, medium and small tubers with no pests, and then dried and stored in the cellar for planting. Digging depth of 1.5m or so, depending on the size of the planting depends on the number, cellar temperature is maintained at about 5 °C ~ 10 °C is appropriate. Below 5°C, planting plants are susceptible to freezing damage; above 10°C, germination is easy to occur earlier. Plants are generally removed in the spring of the following year, and they can also be planted in the fall before freezing. Spring planting, in late March to early April, in the whole area, the spacing is 20~25cm, the spacing is 14~16cm, and the depth is 4~6cm. Then, put the buds up and put them into the hole, one for each hole. After planting soil covered with fertilizer and fine soil, if the drought once poured water. About half a month or so can emerge. Planting large tubers, you can cut two or more pieces, as long as each piece has a robust bud head, can be used for planting. But after cutting, the wound should be wiped with ash in time to avoid rot. Plant tubers after tuber cutting, small tubers, cover soil shallow, large tubers should be deep. Each acre requires about 45kg for planting, and about 20kg for planting.

Second, seed propagation Arisaema seeds mature in early August, after the collection of red berries, placed in water to wash away the pulp, remove the seeds, and immediately autumn broadcast. In the whole seed bed, dig a shallow ditch with a spacing of 15-20 cm, and evenly sow the seeds into the ditch, covering the soil flush with the surface. After the sowing, the water is poured once, and the seedbed is often kept moist. After 10 days, the seedlings can emerge. In winter, it is covered with glutinous rice, moisturizing and moisturizing to help the seedlings overwinter. After the seedlings are unearthed in the spring of the following year, the manure is pressed into the seedbed as a fertilizer. When the seedling height is 6 to 9 cm, the seedlings are planted at a plant spacing of 12 to 15 cm. Excess seedlings can be transplanted separately.
Attachment: Tissue Culture Medium for Arginine Tissue Culture This method is based on the tissue culture of Pinellia ternata. The difference is the selection of different media and the adjustment of the ratio of hormones.

Three harvesting and processing:

Harvested from late September to early October. Late, Nanxing tuber difficult to skin. When digging, pick the tubers on sunny days, remove the dirt, stubble and fibrous roots, and then put them into the basket and place them in running water. Repeat the scrub with the bamboo brush to remove the skin. Wash impurities. Uncleaned tubers can be scraped off with a bamboo knife. Then, fumigation with sulphur: for every 100kg of fresh southern star tubers, 0.5kg of sulfur is required. The degree of smoking through the heart, and then remove the sun, ready-made goods. Tubers can remain white after being smoked with sulfur
