Planting techniques and yield per mu of Amorphophallus

Generally speaking, konjac is a semi-natural plant in rural areas. if you plant one plant, you will send out a lot of plants. after being dug up, you will leave some small seed balls in the field, which can be continued. Moreover, it is a perennial root plant, which dies above ground in winter, sleeps underground, and can grow in the coming year. There is usually no management. However, if planting in a large area, it is necessary to do a good job in cultivation management. Planting konjac does not know what the yield is, which is also a matter of concern to everyone.

1. Output

If you use a generation of konjac seeds to plant, generally one mu of land uses about 100 kilograms of seeds, one kilogram is about 140 seeds. Well, about one mu of land has produced about 4000 jin of second-generation konjac. If you continue to plant, the second generation of taro seed, about a konjac seed is about 100g, planting 3000 plants per mu, one mu can produce 6000 jin of konjac.

2. Planting conditions

Generally, white konjac is planted at medium altitude, while flower konjac is suitable for planting at medium and high altitude. Suitable for planting under the woods, with humus soil, moist environment, shade but light. It is mainly suitable for planting in mountainous areas, and should be planted on non-sunny slopes. It will generally require a higher humidity in the environment, which is beneficial to plant growth. It is required to have a deep and loose soil, which is beneficial to the growth of bulbs.

3. Seed ball treatment

Choose a good, full, no incomplete, no disease and insect harm, there are strong bud eyes of the seed to plant. Use 800 times solution of agricultural streptomycin to soak the seeds for sterilization and disinfection for about half an hour. You can also use a mixture of lime and grass ash to apply to the surface of konjac, and then air for a day or two to disinfect. After that, you can sow the seeds, or you don't have to plant a whole ball, just cut off the budding holes separately with a knife, and the incisions are glued with lime and straw before sowing.

4. Planting method

To determine the planting density, if the seed ball is about 500 grams, the plant spacing is 30 cm, the row spacing is 40 cm; the seed ball size is about 300 grams, the plant spacing is 25 cm, the row spacing is 35 cm; the seed ball is about 100 grams, the plant spacing is 20 cm, the row spacing is 30 cm. Apply basic fertilizer, generally apply 2000 jin of farm manure per mu, but also apply 50 jin of potash fertilizer and 60 jin of compound fertilizer. Furrow sowing, 4 cm covered with soil, covered with pine needles.

The yield per mu of konjac will also be affected by planting management and planting conditions. Under normal planting, the planting method with considerable yield can be used for reference. Planting conditions must be taken into account.
