What kind of environment does yam like to grow in and what is the requirement of yam for soil

Orchids like humidity and grow better in humid environment. However, the humidity inside and outside the basin should be distinguished, and the air humidity should be maintained at about 40-70%. The humidity in the basin needs to be slightly lower, keeping three wet and seven dry. In daily maintenance, whether "dry cultivation" or "wet cultivation" needs to consider the maintenance environment and growth status of orchids. According to the specific situation of specific treatment, such as spring and autumn wet, summer and winter dry; Wet cultivation in the north, dry cultivation in the south, etc.

1. Growing Environment

Yam mainly grows in valleys and slopes between 150-1500 meters above sea level. It likes light. Long time of light can make its branches and leaves more luxuriant, but it is not conducive to the development of tubers. Therefore, if it is planted artificially, it is necessary to control the light time.The suitable temperature of this plant in the seedling stage is 15-20 C, while the adult plant should grow in the environment of 25-28 C. If the temperature is lower than 20 C, the growth of the plant will slow down.

2. Soil Requirements

Yam is generally planted in deep soil, because its tuber is vertical growth, the longest can grow to about 1 meter, if the soil is too shallow, growth will be limited, only some flat and block species can be planted in shallow soil.It should be noted that loose and fertile soil helps the roots to breathe and provide nutrients for their growth.

3. Planting Methods

1. Bulbil: Bulbil grows on the stem of yam and is its plant bud, which can be used for reproduction.Generally, when harvesting, they need to be collected and stored in wooden boxes, but to prevent rat damage, and pay attention to ventilation.In addition, breeding with bulbils requires a year of cultivation in order to obtain root tubers for sowing.

2. Reed head: The reed head is a section at the top of the yam tuber, with a terminal bud on it. Generally, it is cut off at the time of harvesting and kept in a wet place.In spring, the reed head is planted in the soil, and after proper watering, it can germinate and grow into a new plant.It should be noted that reed heads used for many years will deteriorate, so they usually need to be renewed every 2-3 years.
