How many years does it take for yam beans to grow?

Generally speaking, it takes two years for yam grown with yam beans to grow yam beans . However, the yield of yam grown with yam beans is low in the first year, and the yield is highest in the second year. The production period of yam beans is generally within 5 years . Generally, growers can use yam cuttings and yam beans in rotation for planting .

According to the growth habits of yam, if you want to plant yam, the temperature during the sowing period needs to be kept above 10 degrees , and it takes about six months from planting to harvesting of yam. The sowing time is generally chosen in spring .

How to Plant with Yam Beans

Planting time

Yam beans need to be harvested in October in autumn, and large, disease-free yam beans should be selected as seeds. After harvesting, yam beans need to be placed in moist sandy soil for storage, and can be sown in the spring of the following year.

Soil treatment

①Soil pH

The land for yam planting needs to be high, with deep soil, good drainage, and sandy, neutral or slightly acidic soil.

Secondly, pay attention to choosing plots that have not been planted with yam in the past three years to avoid repeated cropping. The plots need to be deep-turned and frozen before winter or in winter to promote soil maturation and reduce soil diseases and insect pests.

② Line spacing

The planting plot needs to be furrowed and made into ridges, and the furrow depth needs to be about 70 cm. The ridge width needs to be determined according to the planting situation. It can be planted in single rows or double rows. The width of the double row ridge is about 90 cm.

③Base fertilizer

About 4,000 kg of decomposed organic fertilizer, 100 kg of plant ash, and 50 kg of superphosphate are needed per mu. Fertilizers are applied to the topsoil layer of 10 to 30 cm. When digging trenches and making ridges, put the excavated topsoil on one side for later use. Put the soil below 30 cm on the other side, and fill the topsoil when filling the trenches. The soil at the bottom of the trench is filled on the upper part of the trench, and the ridge height is about 30 cm.

Yam Planting

When the temperature stabilizes above 10 degrees in spring, you can sow. When sowing, dig a 10-centimeter-deep furrow on the ridge. Put the seed block in, cover it with about 3 centimeters of soil, and keep the soil moist. The spacing between plants is controlled at about 15 to 20 centimeters, and the planting volume per mu is controlled at about 5,000 to 6,000 plants.
