How to plant Chinese yam (seed), with detailed planting techniques

Selection of soil: suitable for growth in loose, fertile, deep soil. Seed treatment: Soak yam seeds in clean water for 6 hours. Sowing seeds: need to dig a 30 cm trench, can be separated by 1 meter dibbling yam seeds. Management work: keep the soil moist, the temperature needs to be controlled at about 20℃. Harvest time: The suitable harvest time is from late October to November.

1. Selection of soil

1. Chinese yam has strong adaptability to the environment, and the requirements for soil are generally not very strict. Coarse sand, pastoral soil and organic fertilizer can be used as the matrix for planting Chinese yam seeds. Such soil drainage is better, which can avoid root rot after seed rooting and germination.

2. Chinese yam likes to grow on hillsides and valleys at altitudes of 150-1500m, as well as in shrubs or weeds by streams and roadsides. It is a short-day, thermophilic crop. The suitable temperature for seedling growth is 15-20℃. The suitable temperature for vigorous growth is 25-28℃. The temperature below 20℃ grows slowly.

3, suitable for growth in loose, fertile, deep soil layer, but flat and block species in the shallow layer, more viscous soil can also grow, drought resistance, but not waterlogging, not suitable for planting in the groundwater table is too shallow, or relatively wet soil, sandy soil and loam suitable water content of about 18%.

II. Treatment of seeds

The method of planting yam seeds is relatively simple. After preparing 1 part of soil suitable for growth, it is also necessary to buy some excellent yam seeds. Generally, yam seeds can be soaked in clean water for about 6 hours, and then the seeds are dried in a cool and ventilated place, and then planted.

III. Sowing seeds

If the plot is planted with yam seeds, it is also necessary to dig a 30 cm trench, loosen the soil with appropriate tools, and sow the seeds of yam at intervals of 1 meter, or directly plant the seeds of yam with pot soil, and plant the seeds at a depth of 5 cm.

IV. Management

Every time the yam seeds are sown, it is necessary to apply enough organic fertilizer as base fertilizer in the soil, which is conducive to promoting the seeds to take root and germinate better. At the same time, appropriate amount of water is sprayed on the soil every day to keep the soil moist. The temperature needs to be controlled at about 20℃, which can accelerate the germination of seeds.

V. Harvest time

The suitable harvest time of yam is from late October to November. When all the stems and leaves of yam wither, tubers can be harvested. Tubers are mainly stored in heat preservation and anti-freezing. The suitable temperature is about 2-4℃ and the relative humidity is about 80-85%. Generally, they can be stored, buried or stored in cellars. In the warm south and Yangtze River basin, they can be listed as soon as they are harvested. The zeroes must be mature before they can be harvested.
