How much is konjac per jin after removing the intestinal sand? Detailed explanation of cultivation methods

Konjac is also known as juruo, ghost taro, and so on. It is a perennial herbaceous plant of the genus Amorphophallus in the Araceae family. China has a long history of cultivating and eating konjac. So, how much is konjac per jin? How is konjac cultivated?Let's find out together!

1. How much is konjac per jin?

Fresh konjac sells for about 2 yuan per jin on the market, but it also varies depending on the place of origin and quality. Konjac seeds are about 5-10 yuan per jin. In China, konjac is mainly distributed in Sichuan, Yunnan, Guizhou and other parts of the southwest and western Hubei. Konjac resources are very abundant around the Sichuan Basin. The Daba Mountains and the Jinsha River valley are both important white konjac production areas in China.

2. Categories of konjac

Konjac has two categories, white konjac and flower konjac, and China has 18 varieties. Konjac has high pharmacological value and edible value, and is also used in health products and chemicals.

3. How is konjac cultivated?

1. Soil selection

The growth of konjac has relatively strict requirements for light, watering, and fertilizer. To plant konjac, you should choose soil that is loose in texture, rich in nutrients, and good in drainage and aeration. Before sowing, remove stones, weeds, and other foreign matter from the soil.

2. Seed selection

① Disinfection of seed corms: First, prepare a large number of high-quality seed corms. Next is sunning the seeds. After sunning them for a full two days, soak them in 500 ppm streptomycin sulfate for half an hour. After removing them, wait until they are dried and sow immediately.

② Sowing method: When sowing, the seed corms and fertilizer must be kept separate. Open the furrow first, then place the seeds, cover with a layer of soil, and then place the fertilizer. After the konjac sprouts, spray agricultural streptomycin once to prevent pests and diseases.

3. Fertilization method

Konjac has a large fertilizer demand during the growing period, especially potassium fertilizer, followed by nitrogen fertilizer. Before planting, sufficient base fertilizer needs to be applied, and fertilizer is applied after the seedlings emerge. The ratio of konjac's demand for the three fertilizers nitrogen, phosphorus, and potassium is 6:1:8. The fertilizer demand also differs at each stage of the konjac growing period. The demand is not large during the seedling emergence stage, but is relatively large during the tuber expansion stage.

4. Field management

① Mulching management: Collect fruit shells, dead leaves, and so on from various crops, chop them up, and evenly and densely cover them over the soil where konjac is planted. On average, about 2 kg of mulch is used per mu, and after September, remove the mulch that has not rotted.

② Weed removal: Because the konjac root system is relatively shallow, weeds should be pulled by hand as much as possible. When pulling them, be careful not to step on the underground rhizomes.

③ Clearing ditches and earthing up: Konjac cultivation requires resistance to drought and waterlogging. If heavy rain occurs during planting, check promptly, dredge ditches and drain water, and ensure there is no water accumulation. At the same time, also pay attention to placing the fine soil from the ditches onto the ridge surface. Earthing up 2-3 times before the growing period can promote the growth of the corms.

5. Pest and disease control

The main diseases of konjac include soft rot, root rot, leaf blight, and so on, with soft rot being more common. After 70% of the konjac has emerged, drench the konjac plants once with oxalic acid at a pH value of 4. After 15 days, use 1000 IU agricultural streptomycin 1000-fold solution combined with 70% thiophanate-methyl 800-fold solution for a second spray control. After another month, use 20% thiodiazole-copper emulsion 500-fold solution for a third spray control. Alternate the two methods for spray control of soft rot.

The main insect pests of konjac include underground pests, sweet potato hornworms, and bean hornworms. You can use cypermethrin 800-fold solution or 80% dichlorvos emulsifiable concentrate 800-1000-fold solution, and omethoate emulsifiable concentrate 800-fold solution alternately for spray control.
