How to plant Amorphophallus konjac how to plant Amorphophallus konjac
1. Amorphophallus konjac can be planted from March to April in spring and from August to September in autumn. Small tubers with a weight of 50-150g, complete shape, full bud eyes and no pests and diseases were selected as seeds. Before cultivation, the seed blocks were dried in the sun for 1-2 days, after the water was slightly dry, the seeds were soaked in 400 times solution of 50% carbendazim or 500 times solution of 50% thiophanate-methyl for 15-20 minutes, and then the seeds were sown after drying.

2. According to the row spacing of 40-50 cm and the plant spacing of 25-33 cm in the whole border, dig holes or plant in ditches, and plant/kloc-0 large seed stems and 2 small seed stems with buds in each hole. After planting, cover the buds with a layer of fine soil with a thickness of 3-4 cm, and finally cover the border with grass to keep warm and moisturize the seedlings, and plant 2000-3500 nests per mu.

3. After the konjac is sown, it is better to collect all kinds of crop straws, pods, dead leaves and other mulches, and spread the mulch evenly, evenly and tightly on the konjac ground to reach the standard of "no grass covered, no ground exposed". Generally, about 2000 kilograms of plastic film is needed per mu, and attention should be paid to removing non-corrupt plastic film after September.

4. Amorphophallus likes humidity. When planting konjac, always keep the soil moist. If there is a dry season, it is necessary to irrigate in time. Drainage should be done in time in rainy season to prevent root rot. After surviving cultivation or when konjac turns green and leaves are released in spring, combined with the first intertillage weeding, apply seedling-promoting fertilizer once, and apply decomposed human and animal manure 1000 kg per mu, or urea 5-1000 kg water. The second intertillage weeding was in May, the third in June and the fourth in August. Combined with intertillage, 2000-2500 kg of decomposed human and animal manure is topdressing per mu, or 25 kg of compound fertilizer is used to irrigate 2000 kg of water.
