How to plant yam seeds? With detailed planting techniques

SummarySelect soil: It is suitable for growing in loose, fertile soil with a deep soil layer. Treat seeds: Soak the yam seeds in clean water for 6 hours. Sow seeds: Dig a 30 cm trench, and the yam seeds can be sown in spots 1 m apart. Management: Keep the soil moist, and the temperature needs to be controlled at around 20°C. Harvest time: The suitable harvest time is from late October to November.

I. Select soil

1. Yam has a relatively strong ability to adapt to the environment, and generally its requirements for soil are not very strict. Coarse sand, garden soil, and organic fertilizer can be used as the substrate for planting yam seeds. This kind of soil has good drainage and can prevent the roots from rotting after the seeds take root and sprout.

2. Yam likes to grow on mountain slopes at an altitude of 150-1500 m, under valley forests, and in thickets or weeds beside streams and roadsides. It is a short-day, thermophilic crop. The suitable temperature for seedling growth is 15-20°C, and the suitable temperature for the vigorous growth period is 25-28°C. It grows slowly below 20°C.

3. It is suitable for growing in loose, fertile soil with a deep soil layer, but flat-shaped varieties and block-shaped varieties can also grow in relatively shallow and relatively clayey soil. It is drought-tolerant but not waterlogging-tolerant, and is not suitable for planting in soil where the groundwater level is too shallow or which is relatively moist. The suitable water content for sandy soil and loam soil is about 18%.

II. Treat seeds

The method of planting yam seeds is relatively simple. After preparing 1 portion of soil suitable for growth, you also need to buy some high-quality yam seeds. Generally, the yam seeds can be soaked in clean water for about 6 hours, then placed in a cool and ventilated place to dry, and then planted.

III. Sow seeds

If sowing yam seeds in a plot, you also need to dig a 30 cm trench, properly loosen the soil with a tool, and the yam seeds can be sown in spots 1 m apart. Alternatively, you can also plant yam seeds directly in potting soil, planting the seeds at a depth of 5 cm.

IV. Management

Each time yam seeds are sown, sufficient organic fertilizer needs to be applied to the soil as a base fertilizer, which helps promote better rooting and sprouting of the seeds. At the same time, spray an appropriate amount of water onto the soil every day to keep the soil moist. The temperature needs to be controlled at around 20°C, which can speed up seed germination.

V. Harvest time

The suitable harvest time for yam is from late October to November. When the stems and leaves of the yam have all withered, the tubers can begin to be harvested. Tuber storage is mainly for heat preservation and freeze prevention. The suitable temperature is about 2-4°C, and the relative humidity is about 80-85%. Generally, pile storage, pit storage, or cellar storage can be used. In the warm South and the Yangtze River Basin, they can be harvested and brought to market at any time. Bulbils must be harvested only after they mature.
