How much is a jin of yam seeds? Detailed planting methods

AbstractPlanting methods for yam seeds: suitable for planting in loose, fertile soil with a deep soil layer. First soak the yam seeds in clean water for about 6 hours, then dig a 30 cm trench, and dibble the yam seeds every 1 m. The soil needs to be kept moist, and the temperature needs to be controlled at around 20°C. The current market price of yam seeds is about 3.5 yuan/jin.

I. How to plant yam seeds

1. Choosing soil

(1) Yam seeds have a relatively strong ability to adapt to the environment, and generally their 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 seeds like to grow on mountain slopes at an altitude of 150-1500 m, under forest in valleys, and in shrubland or among weeds beside streams and roadsides. They are a short-day and warmth-loving crop. The suitable temperature for growth at the seedling stage is 15-20°C, and the suitable temperature during the vigorous growth period is 25-28°C. Growth slows below 20°C.

(3) Yam seeds are suitable for planting in loose, fertile soil with a deep soil layer, but flat-shaped varieties and block-shaped varieties can also grow in shallower, more clayey soil. They are drought-tolerant but not waterlogging-tolerant, and are not suitable for planting in soil where the groundwater level is too shallow or which is relatively damp. The suitable water content for sandy soil and loam is about 18%.

2. Treating the seeds

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

3. Sowing the seeds

If sowing yam seeds in a field plot, you also need to dig a 30 cm trench, properly loosen the soil with a tool, and you can dibble the yam seeds every 1 m, or you can also plant the yam seeds directly with potting soil, planting the seeds at a depth of 5 cm.

4. Management work

When sowing yam seeds, sufficient organic fertilizer needs to be applied in 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, and the temperature needs to be controlled at around 20°C, which can speed up seed germination.
