Suitable growth environment for yam planting conditions

Yam Planting Conditions

Chinese yam likes an environment with plenty of sunlight, but cannot tolerate direct sunlight. It is commonly found on hillsides, under forests in valleys, in bushes or weeds by streams and roadsides. It is suitable for planting in well-drained, loose and fertile loam, and avoids waterlogging.

Huaishan planting climate

The suitable growth temperature for yam seedlings is between 15-20 degrees, and they can withstand short-term low temperatures of 0 degrees. The suitable growth temperature for the aboveground stems and leaves is between 25-28 degrees, and should not exceed 40 degrees. The most suitable temperature for the formation and hypertrophy of yam tubers is 20-24 degrees.

Chinese yam planting area

Only soil that is a mixture of sand and loess is suitable for growing yam. It is generally distributed in areas with an altitude of 350 to 1,100 meters. It mostly grows on hillsides, under forests in valleys, in roadside bushes, by streams, and in weeds.

It is mainly distributed in Japan, North Korea, Zhejiang, Hunan, Hubei, Jiangxi, Fujian, Hebei, Northeast China, Taiwan, Anhui, Shandong, Jiangsu, Yunnan, Guangxi, Guizhou, Henan and western Guangdong in China.

Huaishan planting time

The sowing time of yam needs to be arranged according to the climate of the planting site. It can generally be planted from April to July. The earliest time is April in spring. The germination time is 15 days after planting. During this period, the growth is faster and the germination is more uniform. Those planted in April can be harvested in December of the same year to January of the following year.

The latest sowing time is July 20-30. Seedlings will emerge 20 days after planting. It is the dry season, so the seedlings are weak and the germination is uneven. Those planted at the end of July can be harvested in April of the following year.

Key points for planting yam

After filling the yam roots into the ditch, make a flat frog about one meter above the ditch, and dig a ten-centimeter ditch in the middle. Then water it and wait for the water to seep into the soil. Then plant it at a distance of fifteen to twenty centimeters. Generally, about four thousand can be planted per acre.

Huaishan needs to be weeded in time during the early growth stage, generally once every half a month. After the stems and vines are on the rack, you can stop removing the weeds, but you need to use some soil to support the rack so that the rack forms a convex shape.

Huaishan is a relatively drought-resistant plant, but if you want a higher yield, you need to water it in time, usually when you apply fertilizer for the first time. If it doesn’t rain and the soil is whitish, you need to water it more than twice.
